TL;DR: All Trichogramma programs must address the following four aspects to be successful commercially: selection of the appropriate population is based on inter- and intraspecific variation, as well as on current definitions of parasitoid quality.
Abstract: Major contributions to the release of Trichogramma for biological control of lepidopterous pests have been made in the past 20 years. Most trials have used only five species of Trichogramma against two pests; Ostrinia in corn is considered the most universally feasible. All Trichogramma programs must address the following four aspects to be successful commercially. Selection of the appropriate population is based on inter- and intraspecific variation, as well as on current definitions of parasitoid quality. Mass rearing is comprised of both host and parasitoid components, although major emphasis is now on developing artificial systems. Effective distribution of Trichogramma requires supportive extension and advanced technology. Strategies for use in the field vary according to the approach desired (inundative or inoculative), the timing, frequency and rate of release, and the multiple factors that affect release, such as the weather, crop, host, predation, pesticides, and dispersal. The past difficulty in...

TL;DR: This text provides a broad overview of the use and potential of egg parasitoids in biological control and has been developed by members of the working group "Trichogramma and Other Egg Parasitoids" of the International Organization for Biological Control (IOBC).
Abstract: The importance and advantages of biological control methods in pest management strategies for plant protection are well recognized. Egg parasitoids are among the most significant biological control agents of a number of major insect pests, including pests of corn, sugarcane, cotton, fruit trees and vegetables. Parasitoid species are widely distributed throughout the world and by far the most important are the tiny wasps of the genus Trichogramma. It is estimated that world-wide more than 32 million hectares in agriculture and forestry have been treated annually with Trichogramma. This text provides a broad overview of the use and potential of egg parasitoids in biological control. Its 12 chapters cover both theoretical and practical aspects and have been developed by members of the working group "Trichogramma and Other Egg Parasitoids" of the International Organization for Biological Control (IOBC). The book is thus aimed at a wide audience of advanced students, research workers and advisers in biological control, entomology and crop protection.

TL;DR: Completely parthenogenetic Trichogramma wasps can be rendered permanently bisexual by treatment with three different antibiotics or high temperatures, which strongly suggests that maternally inherited microorganisms cause parthenogenesis in these wasps.
Abstract: 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 100% females were never considered because the lack of males would prevent the host's reproduction.
