Trichogramma are tiny parasitic wasps used for biological pest control in agriculture. They lay their eggs inside the eggs of pest insects, preventing them from hatching and reducing pest populations. They are commonly used in integrated pest management programs to reduce chemical pesticide use.

Is there a biological control for pesty caterpillars?
Yes, Trichogramma parasitic wasps are effective biological controls of pesty caterpillars.Specifically, biological controls tend to take two main forms. One is as predatory micro-organisms, such as the use of Bacillus thuringiensis against infestations of bagworms, caterpillars, hornworms and loopers. The other is as predatory insects, mites and nematodes. Trichogramma wasps are examples of the latter.
What is a gamma trica wasp and what does it look like?
The Trichogramma wasp is the smallest insect in existence within the world. These wasps have constricted abdomens, short antennas and raspberry colored eyes.
How do you get rid of pecan worms?
Pecan worms can be controlled by applying trichogramma wasps which are quite good in checking pecan case-bearers. Application of certain chemicals may also help.

Do wasps eat butterflies?
I can't answer that question exactly but what I can say is ants eat wasps they will eat anything for the nest. I only know this to be true as on holiday a wasp was annoying me constantly so I hit it when I came back from the beach I found the dead wasp on the floor with ants inside of its abdomen eating it and taking parts of it to the nest.
What are some examples of good guy insects?
Beneficial garden insects include pollinators, predators, and parasitoids, or parasitic wasps.Pollinators visit flowers to collect nectar and pollen to feed their young. In visiting many flowers, they transfer pollen from one flower to another, fertilizing seeds. Some garden vegetables can reproduce without pollinators--corn, for example, is wind pollinated--but in most fruiting plants, pollinators are either necessary for producing fruit, or fruit produced from cross-pollinated flowers is larger and has a longer shelf life than self-pollinated fruit. European honey bees are the most important agricultural pollinators, but orchard mason bees, bumble bees, and other native pollinators also pollinate vegetable crops.Parasitoids are wasps that lay their eggs in the eggs--or bodies--of other insects. Most are tiny, gnat-sized insects with a wingspan of 1-2 mm, like trichogramma wasps, but some are larger. Larger parasitoids lay their eggs in caterpillars and the nymphs of beetle pests like squash beetles or spotted cucumber beetles. Parasitoids are critical insects in natural garden pest control because they control insect pests at low population densities, before they get out of hand. These tiny garden allies are the first insects to die when pesticides are applied. They're wiped out long before the pest insects.Predators are the cleanup crew. Predator population increase in response to rising prey populations, but there's always a small lag before their numbers are high enough to control a severe infestation. Wasps, spiders, preying mantises, predatory flies like robber flies, syrphid flies, and beetles like lady bird beetles (ladybugs) and ground beetles are examples of predatory insects. Ladybugs, and especially their larvae, are voracious predators of aphids, scale insects, and mealybugs.Pollinators increase crop yields and improve produce quality. In organic gardens, parasitoids and predators work together to keep pest insects in check. They don't wipe pests out--after all, pest insects are the food of predators, and the incubators of parasitoids--but they do keep their numbers low, below the threshold for economic damage. In a healthy organic garden, you'll see many different kinds of insects, just not too many of any single pest.
