Small-scale Rearing of Anagasta kuehniella for Trichogramma Production

By CAB International

This technical guide describes the techniques for small-scale rearing of the egg parasitoids Trichogramma spp. in the factitious host Anagasta kuehniella. These parasitoids are among the most widely used natural enemies in the world, and in Brazil are used to control lepidopteran pests in a wide variety of crops, including sugarcane, corn, soybean, cotton, vegetables (tomatoes, potatoes), fruit (avocado, citrus, grapes), and tobacco.

Preface

The use of biological control (BC), especially to control agricultural pests, has been increasing by 10–15% annually worldwide. Insect rearing is of prime importance for the success of BC programs, especially for macro-organisms. Many commercial firms currently mass-rear and sell these control agents. The programs using control agents, especially in Brazil, were initially developed by government agencies and today are conducted by commercial firms. Some of these companies have developed the capacity to supply large-scale control programs, and some are start-ups or smaller companies that meet local requirements. Whatever the eventual purpose, all BC programs must start with small-scale insect rearing, so-called research rearing, in order to learn the capabilities of both the pest and the natural enemy.

For releases of macro-organisms in greenhouses or in open fields, smaller or larger rearing systems are used, depending on the number of insects needed. Small- and medium-scale production of insects is used for classic biological control, with inoculative releases, and largest-scale production is for augmentative biological control, with inundative releases. Natural enemies are usually produced on the host that they parasitize in the wild (natural host), or when possible, on a factitious host in order to simplify the rearing procedure or to reduce the production cost.

The development of artificial diets for pest rearing has greatly simplified the process of rearing natural enemies. These artificial diets have significantly advanced mass-rearing techniques, especially for pests
