Abstract
The effect of topical application of Artemisia annua oil on the development and reproduction of Dysdercus koenigii was studied. On the basis of 48 h m ortality, the LD50 for fifth instar nymphs was 0.48 mu l/nymph. The treated nymphs showed 2 days delay in development, and also produced intermediates . The treatment decreased haemolymph protein concentration and disturbed it s electrophoretic protein pattern. The adults which emerged from treated ny mphs showed poor ovary development. There was a greater median neurosecreto ry activity in the treated insects compared with control insects till day 6 of adult life.
