The Evolution of Deterrent Responses in Plant­ Feeding Insects

摘要: A plant deterrent may be defined as “a chemical which inhibits feeding or ovi-position when present in a place where insects would, its absence, feed oviposit” (Dethier et al. 1960). In general, we believe that behavioral deterrence caused by such chemicals plants plays major role host selection 1954; Jermy 1966; Bernays and Chapman 1977), the effectively protect most from insects. All have complex profile of secondary compounds ranging number few to hundreds there are an estimated 100,000–400,000 different terrestrial species (Swain 1977). Most been investigated one other insect tested. The more restricted insect’s range, found lower threshold for rejection deterrents (Jermy 1983).
