Abstract

The tea mosquito bugs, Helopeltis theivora Waterhouse prefer to deposit eggs mostly (66%) in the pluckable part of tea plants (Camellia sinensis) in North East India. But, in course of control measures while they were exposed to pesticides they were apt to change the ovipositing sites on the tea shoot. In the laboratory, following exposure to endosulfan 30 EC and deltamethrin 2.8 EC H. theivora deposited around 60% eggs in the non-pluckable part in contrast to only 34% in control i.e. when untreated.
