Abstract
Eggplant is one of the important food plant and is consumed on daily basis around the World. Eggplant is attacked by several insects which affects the growth of egg plants. Insects have developed the resistance against insecticides which are usually sprayed on them. Jassids attack more on egg plants and are difficult to control with normally sprayed insecticides. Experiment was conducted to observe the resistance development in jassids against imidacloprid which is sprayed against this pest. In this experiment recommended and lower concentrations were used to observe the resistance development, if any, in jassids. Experiment was conducted in petri dishes, adults and nymphs were tested separately in two tests. In experiment leaf was sprayed with insecticide in comparison to control petri dishes. One petri dish was having one adult and one nymph in each tests. Ten petri dishes for each experiment were observed for each treatment. Results showed that mortality was higher in recommended concentration test as compared to control for both adults and nymphs of jassids. While mortality was low at lower concentration in both tests of nymphs and adults as compared to control. These experiments explicitly reveal that mortality of jassids was in conjugation to concentration. As conclusion it can be asserted that resistance is not developed in jassids against imidacloprid. Instead more research is needed in future to observe its biochemical pathways in jassids.
