PEST CONTROL

SUBSTRATE

Contender Gardens is using two types of substrate and fertilizer: a soilless substrate Using Dutch Master Nutrients.  An Organic amended soil, using CPG Nutrients.

Because Contender Gardens’ highest priority is R & D, when growing new strains, these two mediums and feeding methods allow us to discover how to grow each strain to full potential.

 

BIOLOGICAL CONTROL AGENTS

BENEFICIAL INSECTS WE USE:

Aphidius Colemani

Aphidius Colemani

Aphidius colemani

Target Pest: Aphids

Description: Aphidius species are a group of native parasitic wasps, frequently found parasitizing aphids in greenhouses and outdoor crops. Adults are tiny (2-3 mm long), dark colored wasps that do not sting. The larvae develop entirely inside the host aphid, which eventually become rigid mummies when the larvae pupate. Aphidius is an outstanding searcher, and can locate new aphid colonies even when aphid populations are low.

Use in Biological Control: When aphid populations are high, Aphidius colemani alone will not provide adequate control, but they work well in conjunction with Aphidoletes and ladybugs to provide control. Effectiveness may be reduced in late summer when "Colemani" itself may be attacked by naturally occurring hyperparasites. These are even smaller parasitic wasps that will parasitize the Colemani as well as the aphid, and will emerge instead of the Colemani. While this can be damaging to a biocontrol program, modern processes can ensure that this is a rare situation. 


Aphidoletes Aphidimyza

Aphidoletes Aphidimyza

Aphidoletes aphidimyza

Target Pest: Aphids

Description: Aphidoletes larvae are voracious native predators of over 60 species of aphids. The larvae are legless maggots about 3 mm long, and orange in color which make them easy to spot in foliage. Adults are small midges resembling mosquitos that are nomadic (they will seek out heavy aphid populations to lay eggs near) and can be hard to find. They are most easily spotted in the evening, and may be found hanging (unstuck) from spider webs were mating often takes place.

Use in Biological Control: Aphidoletes are used to control aphids indoors in commercial greenhouses and interior plantscapes. They may also be used outdoors in zoos, orchards, shade trees, roses, home gardens, and botanical gardens.

Optimum conditions for Aphidoletes are 70-77° F (21-25° C) and relatively high humidity (70%). This is especially important for the pupal stage, which must not dry out. If aphids are present in outdoor plants in late summer, a release of Aphidoletes at this time helps reduce the overwintering aphid population, while establishing overwintering predator populations that will be active early the following spring. 


Green Lacewing Larva

Green Lacewing Larva

Green Lacewing Larva

Chrysoperla rufilabris

Target Pests: Aphids, Mites, Thrips, Moths, and other soft bodied insects

Description: Green lacewing adults are green or brown, about 0.5 – 0.75 inches (1-2 cm) long. They have transparent, finely veined wings that are longer than their body. Adults are active at night and feed only on pollen and nectar, which they need in order to lay eggs. Larvae are spindle-shaped with pincher-like mouth-parts. Lacewing larvae are often referred to as alligators due to similarities in appearance.

Use as Biological Control: Lacewings come supplied as either eggs, larvae or adults. Adults will travel around to find aphid populations, but larvae are the only predatory form of this species. Further, while aphids are their main target, they will also attack other soft-bodied insects (e.g. moths, scale, thrips, mealybugs, etc.). Because larvae are fierce predators, they may begin to cannibalize when packaged in close proximity to each other. If larvae are purchased in bottle form, they must be distributed immediately upon receipt. 


Amblysieus Andersoni

Amblysieus Andersoni

Amblyseius andersoni Slow Release

Target Pests: broad mite (Polyphagotarsonemus latus), cyclamen mite (Phytonemus pallidus), two-spotted spider mite (Tetranychus urticae), red spider mite (Tetranychus cinnabarinus), tomato russet mite (Aculops lysopersici), rust mite (Eriophyidae)

Description: Andersoni occurs naturally throughout Europe and North America. It is primarily found in areas of grape and apple production, but also in soft fruit, peaches, deciduous ornamentals and conifers. Andersoni feeds on many types of small arthropod prey and pollen.

An adult Andersoni is beige and less than 1 mm long. Females lay about 35 eggs during its lifetime. Young larvae have 6 legs; while the next 2 nymph stages have 8 legs (like an adult).

Use in Biological Control: Andersoni is a predatory mite that can be used to control a range of mite pests. This predator is ideal for vegetables, hardy ornamentals and fruit crops. It controls the red spider mite, two-spotted spider mite, fruit tree red spider mite and the russet mite.

It is active at lower temperatures than other predatory mites, which means they can be introduced much earlier in the growing season than some other predators.


Amblysieus Cucumeris

Amblysieus Cucumeris

Amblyseius cucumeris Slow Release

Target Pests: Broad mites, Hemp Russet mites, Cyclamen mites, Western flower thrips, Onion thrips, and Bamboo mites

Description: Cucumeris is a species of predatory mite that feeds on immature stages of thrips. It also feeds on pollen, two-spotted mites and other species of mites. Adults are pear-shaped, tan in color, and less than 0.5mm (1/50th in.) long. Eggs are round, transparent, and 0.14mm in diameter.

Use as Biological Control: Cucumeris is mainly used to control western flower thrips on greenhouse vegetable and flower crops. Cucumeris will also feed on pollen in the absence of thrips, which makes for great use as a preventative measure. Optimum conditions are 68-77°F (20-25°C) with relative humidity of 66-70%. 


Amblysieus Fallacis

Amblysieus Fallacis

Amblyseius (Neoseiulus) fallacis on bean leaves

Target Pests: Two-spotted spider mite (Tetranychus urticae), Broad mite, Hemp Russet mite, European red mite (Panonychus ulmi), Spruce spider mite (Oligonychus ununguis), Southern red mite (Oligonychus ilicis), Bamboo mite (Schizotetranychus celarius), Cyclamen mite

Description: Fallacis is a native predatory mite that feeds on several different mites, including spider mites and rust mites, as well as other small insects. Fallacis may also feed on pollen, and can survive for periods on pollen alone, which makes them an excellent preventative insect. It is one of the most important biological control agents in North American berry and orchard crops. Adults are bout 0.5mm long, with pear-shaped bodies. They are tan to light orange in color, shiny, with long legs. Immature Fallacis are cream colored and semi-transparent. Eggs are oval and about 0.3mm long.

Use as Biological Control: Fallacis is used to control two-spotted spider mites (and other mites) on greenhouse peppers, field strawberries, raspberries, currants and mint. In British Columbia, Washington, and Oregon, Integrated Pest Management (IPM) programs for field berry crops are based on using Fallacis as the primary control for spider mites. Fallacis is more resistant to pesticides than most biological controls, and a strain highly resistant to pesticides is available commercially. Unlike other predatory mites, such as the Persimilis, Fallacis can remain in areas with low levels of spider mites by feeding on other small arthropods and pollen. Fallacis feeds and reproduces over a wide range of temperatures (48-85°F). They do best where there is a dense plant canopy and when relative humidity is over 50%. Fallacis can reproduce at lower temperatures than other predatory mites and displaces them in cooler growing areas in the Northern United States.


Amblysieus Swirskii

Amblysieus Swirskii

Amblyseius swirskii Slow Release

Target Pest: Whiteflies, Thrips, Broad mites, Hemp russet mite

Description: Amblyseius swirskii adults have 8 legs and the body is a whole unit as opposed to segmented. It has relatively few hairs on its back, 20 pairs at most. A. swirskii cannot be distinguished from a number of other predatory mites such as A. cucumeris, A. californicus, or A. andersoni with the naked eye. The differences in appearance are subtle and can only be seen under microscope. The color of A. swirskii is dependent on what the mites have been eating. This can vary from dark red to purple, to light yellow. With thrips and whitefly as prey, the color tends to be a kind of light orange. The mites feed by piercing small arthropod prey or grains of pollen with their mouthparts, and draining the contents.

Use in Biological Control: Amblyseius swirskii is a predatory mite native to the coastal regions of the Middle East and North Africa on fruit trees. It is an ideal product to be used in crops that are grown under protection in warm conditions, such as peppers, cucumbers, gerbera and aubergine. It can be used on other crops during the summer, provided that average daytime temperatures exceed 20 °C. It breeds extremely quickly under warm and humid environmental conditions. It predates on thrips, whiteflies and other pests. In the absence of prey it can also survive on the plant by feeding on pollen and mold. It prefers a warm and humid climate, but can survive cooler nights during the winter months in semi-protected crops by moving lower down the plants where it benefits from the warmer micro-climate closer to the ground. This mite is available in a Gemini and hooked sachets, which allows quick and easy introductions into the crop. The mite will emerge onto the crop looking for prey.


Neosieulus Californicus

Neosieulus Californicus

Neoseiulus californicus in Corn Grit

Target Pest: Two-spotted spider mite (Tetranychus urticae), Broad mite, Cyclamen mite, General mite predator, Hemp russet mite

Description: Californicus are tiny (0.5mm long), pear-shaped and tan in color. Males are much smaller and darker in color (dark brown) than females. There are usually slightly more females in Californicus populations.

Use in Biological Control: Californicus is a general predatory mite that primarily attacks spider mites, but will also feed on many other leaf inhabiting mites (even some microscopic species), other small insects and pollen. While Californicus is mainly used in greenhouse crops, it may also be used in the field, particularly in fruit crops (strawberries, pome, and stone fruit). Other suitable crops include vegetables (capsicum, tomatoes, eggplant and cucumber), ornamentals (gerberas, chrysanthemums and roses) and herbs.

Californicus is tolerant of various temperatures and low humidity, but works best under warm to hot conditions. It tolerates higher temperatures and lower humidity than Persimilis. When pests are low, Californicus will feed on pollen which keeps predatory populations around your crop. While some predators will actively seek out new prey in the absence of food, most will stay on the crop and wait for the arrival of new pests.


Stratiolaelaps (Hypoaspis)

Stratiolaelaps (Hypoaspis)

Hypoaspis (Stratiolaelaps scimitus Womersley)

Target Pests: Fungus gnats (Bradysia spp.), Western flower thrips (Frankliniella occidentalis), Root aphids, Mites

Description: Stratiolaelaps (Hypoaspis) is a native species of soil-dwelling mite, which feeds on small insects and mites (e.g. springtails, root mealybug crawlers, and spider mites). Adults are tan in color, less than 1 mm long (1/20th in.) and move rapidly over the soil surface. They live, eat, and reproduce in the soil medium and walkways on the greenhouse floor.

Use in Biological Control: Stratiolaelaps are used primarily to control young larvae of fungus gnats in the soil or planting media. They also help control soil stages of thrips and may account for up to 30% of thrips control. They do not control shore flies or moth flies, but will feed on other soil organisms, such as springtails and root mealybugs. They have been used successfully in bedding and potted plant production, seedling and cutting propagation, and poinsettia stock. Stratiolaelaps adapt well to the various growth media and capillary mats used in plant production, but do not survive freezing or flooding conditions.


Rove Beetle (Delotia Coriaria)

Rove Beetle (Delotia Coriaria)

Rove beetle (Dalotia coriaria) or Atheta coriaria

Target Pests: Shore flies (Ephydridae), fungus gnats (Sciaridae), western flower thrips (Frankliniella occidentalis), root aphids

Description: Rove beetle (Dalotia coriaria), formerly known as Atheta coriariais a native species of a soil-dwelling rove beetle which feeds on small insects and mites. Both adults and larvae are active aggressive predators and are attracted to decomposing plant or animal material and algae, where their hosts are found. While they are beetles, they do not necessarily look like beetles. They are light to dark brown in color, with adults being 3-4 mm long. They are slender with short wing covers. Rove beetles have an interesting habit of curving their abdomen upwards like scorpions and can run or fly when disturbed (usually close to the ground). Since they can actively fly, they rapidly colonize the release area. However, too many Atheta in flight may be because of disturbance to their home.

Use in Biological Control: Rove beetles are used primarily to assist in the control of shore flies and fungus gnats and other small arthropods in the soil or planting media. They also help control soil stages of thrips and feed on most other small soil organisms such as moth flies, springtails, and root mealybugs.

It has been used successfully in vegetable, bedding and potted plant production and seedling and cutting propagation. Atheta adapts well to the various growth media (including rockwool and coconut fiber) and capillary mats used in plant production. They will not survive freezing or flooding conditions.


Phytosieulus Persimilis

Phytosieulus Persimilis

Phytoseiulus persimilis on bean leaves

Target Pest: Two-Spotted spider mite (Tetranychus urticae)

Description: “Persimilis” is a tropical predatory mite that was one of the first greenhouse biological control agents available commercially. Adults are bright reddish-orange in color, with long legs and pear-shaped bodies (about 0.5mm long). Immature predators are a pale salmon color. Eggs are oval and about 0.3mm long, which is about twice the size of the spider mite eggs.

Use as Biological Control: Persimilis is very effective against two-spotted spider mites in greenhouse vegetables and ornamentals, interior plantscapes, and conservatories. It can also be used in warm climates on field crops such as strawberries. Optimum conditions are 68-81°F (20-27°C) and relative humidity from 60-90%. While these are optimum conditions, they are not necessarily essential for Persimilis to be successful. Please note however, that cooler or warmer temperatures may affect reproduction and development. At optimum temperatures, the predators reproduce faster than spider mites, while at warmer and cooler temperatures, the spider mites will reproduce faster


Galendromus Occidentalis

Galendromus Occidentalis

Galendromus occidentalis in Corn Grit

Target Pest: Two-spotted spider mite (Tetranychus urticae), Citrus red mite (Panonychus citri), McDaniel spider mites, Yellow spider mites, Apple and Pear rust mites, Prunus rust mites, Blister mite, and European red mite (Panonychus ulmi)

McDaniel spider mites, yellow spider mites, apple and pear rust mites, Prunus rust mites, blister mites, and European red mites.

Description: Occidentalis are very similar in appearance and life cycle to Fallacis and Cucumeris. Adults are pear-shaped mites that are less than 0.5mm long. They range in color from beige, amber and red. They are able to hunt in extremely hot conditions, without requiring a high humidity (at least 50%).

The eggs are pear shaped, almost transparent, but slightly larger than the round European red mite eggs. The larvae are also transparent and difficult to see without a microscope. Of the five G. occidentalis life stages, only the larvae are six legged. All other post-egg stages have eight legs. In all stages, G. occidentalis is indistinguishable from Neoseiulus fallacis and Galendromus pyri, other phytoseiid predatory mites, without a compound microscope.

Use in Biological Control: Occidentalis feeds primarily on spider mite nymphs and adults, but not eggs. It will also feed on pollen when mite populations are low. The predators are well adapted to hot conditions as long as relative humidity is over 50%. It does well under high or low temperatures, and is more effective than Persimilis in tree top foliage and on hairy leaves. Note that Occidentalis will go into diapause in colder conditions.

This mite predator does best in warm weather (80° to 110° F) and prefers humidity 30% or less. In temperatures less than 80° F it may go into hibernation or slow down consumption of mites considerably. Ideal for use on fruit trees, vegetable, grape and field crops. Use in a greenhouse only if plants are maintained as low as 40% RH.


Mesoseiulus Longipes

Mesoseiulus Longipes

Mesoseiulus longipes in Corn Grit

Target Pest: Two-spotted spider mite (Tetranychus urticae)

Description: Longipes are pear-shaped mites that are less than 0.5mm long. They range in color from beige, amber and red. They are able to hunt in warm conditions (like Occidentalis), but differ in that they are also able to hunt in extremely dry conditions.

Use in Biological Control: Longipes are similar predators to Persimilis, but can survive at a lower humidity. Optimum conditions for Longipes are temperatures between 65-90°F, with a relative humidity of 40-60%. While they are effective in extremely hot temperatures, humidity will need to increase as temperature increases. Longipes are most effective in warm greenhouses and interiorscapes.


Stethorus Punctillum (Spider Mite Destroyer)

Stethorus Punctillum (Spider Mite Destroyer)

Spider Mite Destroyer - Stethorus punctillum

Target Pests: Two-spotted spider mite (Tetranychus urticae), European red mite (Panonychus ulmi), Spruce spider mite (Oligonychus ununguis), Southern red mite (Oligonychus ilicis)

Description: Stethorus punctillum, the Spider Mite Destroyer,  is a specialized spider mite predator in the lady beetle family. Adults are tiny and oval shaped, 1.5mm (1/10 in.) long, dark brown to black in color, with brownish-yellow antennae, mouthparts and legs. Larvae are slow moving, grey with conspicuous legs. They move from plant to plant on leaves.Eggs are yellowish ovals, laid singly in or near mite colonies. Adult beetles can fly, and have an unusually good ability to find small infestations of spider mites.

Use in Biological Control: When combined with other biological control agents such as predatory mites, Stethorus can improve the management of a variety of pest mites in greenhouses, interior plantscapes, and nurseries. Optimum conditions are moderate to high temperatures of 67-90°F (16-35°C). They may remain active and feed, but will not fly at temperatures below 54°F. 


Nemasys Steinernema Feltiae

Nemasys Steinernema Feltiae

Nemasys - Steinernema feltiae

Target Pests: Larval stages of fungus gnats (Bradysia spp.), adult and pupal stages of western flower thrips (Frankliniella occidentalis)

Description: Beneficial nematodes are microscopic worms that attack and kill targeted insects, without affecting any other organisms. Within the infected insect, the beneficial nematodes continually reproduce and then spread out for long term control.

Use in Biological Control: Nemasys is a proprietary formulation of the naturally occurring insect-parasitic nematode Steinernema feltiae. These nematodes are released in their infective juvenile stage to search out and enter insect pests. Once inside, the nematodes release symbiotic bacteria that quickly kill targeted insects. Reproduction inside the insect releases new generations of infective juvenile nematodes that disperse in search of further prey. When applied to the soil, Nemasys will provide prolonged protection against pest re-infestation.


Trichogramma

Trichogramma

Trichogramma minutum

Target Pests: Several species of moths, including cabbage looper, codling moth, oriental fruit moth, twig borers and fruit worms. This product is best for moth control in an orchard or tall crop setting, meaning over the 8-10 foot range.

Description: Trichogramma is a minute parasitic wasp that attacks the eggs over 150 species of moths including cabbage looper, codling moth, oriental fruit moth, twig borers and fruit worms. Adults are less than 1/25 in. (1 mm) long. Larvae develop entirely inside the eggs of moths. The eggs darken when they are parasitized.

Use in Biological Control: Several different species of Trichogramma are used in North American crops. For greenhouse crops use T. pretiosum. In orchards and field crops use T. minutum in the east and T. platneri in the west. New species such as T. sibericum are being used in greenhouse trials.

Optimum conditions are moderate temperatures of 68-81 ºF (20-27 ºC) and relative humidity 60%.  Moth species that lay eggs in clusters are more easily controlled using Trichogramma than those that lay eggs singly.


Orius Insidiosus

Orius Insidiosus

Orius insidiosus

Target Pest: Western flower thrips (Franklinella occidentalis), Onion thrips (Thrips tabaci)

Description: Orius is a predatory bug that feeds on many species of small, soft-bodied insects and pollen. Adults are 2-2.5 mm long, mostly black with lighter markings on the wings. Nymphs are colorless when they hatch, darkening to yellow and dark brown as they grow. They grow from 0.5 mm long to 1.8 mm long. Orius moves quickly at all stages. Orius adults are good flyers and move efficiently throughout a greenhouse to locate prey. Adults are attracted to, and can often be found in flowers. 

Use in Biological Control: Orius has been shown to be an effective control of western flower thrips in cucumber and sweet pepper greenhouses. It is not effective for thrips control in tomatoes. Orius are generalist predators that consume a variety of pests including mites, aphids, and small caterpillars. They are most effective for pests with life stages that inhabit flowers such as flower thrips. Optimum conditions are temperatures over 59 °F (15 °C) with relative humidity over 60%. Typical greenhouse temperatures of 64-82 °F (18-20 °C) are suitable for Orius development.
