Artificial Diet for Rearing Trichogramma Wasps (hymenoptera: Trichogrammatidae) with Emphasis on Protein Utilization
Trichogramma wasps are tiny hymenopterous egg parasitoids widely used in biological control programs worldwide. The huge quantities of insects necessary for inundative releases are mainly produced on factitious hosts like Ephestia kuehniella (Zeller) (Lepidoptera: Pyralidae), or on silkworms. In order to simplify production, increase its flexibility, and potentially reduce cost, studies on arti...
متن کاملDeveloping Trichogramma (Hymenoptera: Trichogrammatidae) as a pest management tool
The egg parasitoid, Trichogramma (Hymenoptera: Trichogrammatidae), is used extensively around the world as a biological control agent for the control of lepidopterous pests. Wasps are either released to augment an existing population “inoculative release,” or they are released in large numbers to coincide with maximum pest pressure “inundative release.” Field releases however, have had variable...
متن کاملAntibiotics cause parthenogenetic Trichogramma (Hymenoptera/Trichogrammatidae) to revert to sex.
Completely parthenogenetic Trichogramma wasps can be rendered permanently bisexual by treatment with three different antibiotics or high temperatures. The evidence strongly suggests that maternally inherited microorganisms cause parthenogenesis in these wasps. Theories predict female-biased sex ratio in offspring under the influence of maternally inherited symbionts, but extreme sex ratios of 1...

متن کاملDo Trichogramma minutum Riley and Trichogramma bennetti Nagaraja & Nagarkatti (Hymenoptera: Trichogrammatidae) occur in Brazil?
According to some catalogues, Trichogramma minutum and T. bennetti have been recorded in Brazil. However, the information obtained in studies with Trichogramma in recent years indicate that those species do not occur in Brazil.
