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.
