In vitro rearing of entomophagous insects - Past and future trends: a minireview

摘要: In vitro rearing of entomophagous insects (IVREI) can be conducted with two main aims: firstly to develop an efficient tool for researches on insect biology, physiology, and behaviour, secondly mass-produce applied use. It was conceived in the 1940's, but really investigated from 50's. Several teams, including less than one hundred researchers, distributed among about a dozen countries, were implicated these investigations. Hymenoptera, Diptera, Rhynchota, Coleoptera are prin- cipal orders studied. The best results obtained egg or pupal hymenopterous parasitoids, tachinid larval parasi- toids some polyphagous predators. future research structures will need constitution national supra-national con- sortiums between public private institutions share financial means teams. species that expected developed artificial conditions biological control hand species-specific parasitoids reduce unexpected side ef- fects, other hand, predators simultaneously several pest insects. production go through more automation quality control, costs produced guarantee reliable efficiency. To reach objectives, investigations development towards innovative tools define adapted diets find new criteria.
