Electro-Antennographic Response of Helopeltis theivora to Synthetic Pesticides Used in Tea Plantations
Helopeltis theivora is considered as one of the major pest in tea plantations causing considerable economic damage. Recent control strategies against this notorious polyphagous pest mainly depend on the application of insecticides. The study is focused on the antennal response of H. theivora on exposure to different insecticides using electroantenogram (EAG). The result showed that the insects perceive quinalphos as they are frequently exposed to it. The hierarchy of the EAG response of exposed and unexposed insects was quinalphos > bifenthrin > deltamethrin > thiamethoxam.
