Review A Ten Year Perspective of Insect Science 1980–1989


Selected studies in chemical ecology are described that have led to the identification of semiochemicals playing key roles in pest behaviour. In some instances, these compounds can provide alternatives to insecticides, but novel integrated control programmes including use of semiochemicals are described which have greater potential for the future. Thus, semiochemicals can be used to increase the efficacy of entomophagous fungi and to manipulate populations of beneficial insects. New strategies are being developed which use both antifeedant and attractant semiochemicals to deter insects from crops and aggregate them in areas where they can be destroyed. For the long term, strategies are described that employ genetic manipulation of crop plants so that pests are controlled by semiochemicals produced directly in the plants.

Key Words

Mots Clefs

Une etude sur l’identification des substances semio chimiques qui jouent un role important sur le comportement des ravageurs fut faite. Dans certains cas ces substances peuvent servir d’alternative aux insecticides. Dans cette publication l’importance d’un nouveau programme de gestion integrée contre les ravageurs base sur les substances semio chimiques a èté decrit De ce fait ces substances peuvent ètre utiliser pour ameliorer l’efficacite des champignons venereux attaquant les insectes et manipuler les populations d’insectes utiles. Des strategies nouvelles basées sur les substances semio chimiques qui attirent ou repulsent les insectes sont entrain d’ètre developper afin de grouper ces insectes pour les detruire. A long terme des strategies qui necessitent les manupilations genetiques des plantes afin de produire des substances semio chimiques capables d’aider dans la lutte contre les ravageurs ont èté decrites.
