There have been more than a thousand papers published on Trichogramma and they are the most used biological control agents in the world.

However, their eggs are susceptible to biological control by Trichogramma wasps.

Trichogramma represent around 80 genera from the Trichogrammatidae family with over 800 species worldwide.

Although there are several egg parasitoids commonly used throughout the world, Trichogramma have been the most extensively studied.

Trichogramma are small and very uniform in nature which causes difficulty in identifying the separate species.

This most likely has contributed to the difficulty in separating the morphologically similar Trichogramma genera.

Trichogramma evanescens has been released in the Philippines.

Some forms of parthenogenesis in Trichogramma are genetically based and are not associated with microorganisms.

This suggests a monophyletic origin for Trichogramma parthenogenesis bacteria.

Trichogramma species vary in their host specificity.

Diagnostic positions for the Trichogramma parthenogenesis microorganisms are boxed.

Trichogramma evanescens is a parasitic wasp of Lepidoptera eggs.

He placed a swatch containing trichogramma, or tiny wasps, on a branch of the Gormals' maple tree.

Trichogramma brassicae is a wasp species.

Trichogramma wasps are minute (around 0.5mm) parasites of insect eggs, primarily those of Lepidoptera.

Biosystematics of Trichogramma and Trichogrammatoidea species.

Trichogramma are used for control on numerous crops and plants, these include cotton, sugarcane, vegetables, sugar beets, orchards and forests.

Though Australia has its own native Trichogramma species there has not been much work undertaken to commercially use them for biological control within Australia.

An example of a parthenogenic species is the Trichogramma wasp, which has evolved to procreate without males with the help of Wolbachia.

Trichogramma are minute polyphagous wasps, commonly known as stingless wasps, that are endoparasitoids of insect eggs.

The first description of a Trichogramma species was in North America in 1871 by Charles V. Riley.

Trichogramma pretiosum is the most widely distributed Trichogramma species in North America.

Trichogramma pretiosum was originally used to describe Trichogramma from hosts on non-arboreal plants such as cotton.

Elsewhere there is renewed enthusiasm for rearing Trichogramma, a small wasp which parasitises the eggs of many species, such as Heliothis, the cotton bollworm.

Trichogramma minutum is one of the most commonly found species in Europe and was first mass reared in 1926 on eggs of Sitotroga cerealella.
