Electroantennography of terpene volatile compounds with insecticidal activity
Abstract
Synthetic insecticides have adverse effects on non-target organisms, ecosystems and human health due to their high toxicity and residual accumulation in different environmental components and organism tissues. Moreover, their long-term applications generate the development of pest resistance. This has led to a growing interest in novel, more environmentally friendly insecticides. Essential oils and their active constituents, especially monoterpenoids, which play an important role in plant defense system against microorganisms, insects, herbivores and allelopathic interactions, are considered as an alternative to synthetic insecticides. Electroantennography (EAG), a technique widely used in insect olfaction studies, is performed in the present work on males of the Noctuid Agrotis ipsilon to characterize the electrical response evoked by well-known natural insecticides from the peripheral nervous system of insects.
