The pest completes its life cycle in about 30 days and has 9 generations in a year. During severe infestation premature leaf shedding is caused, resulting in a poor and stunted growth of this valuable crop. In insecticidal trials, out of 5 test chemicals Lebayucid 50%proved most effective against larvae at 0.05%level and against pupae at 0.1%level. Ekalux gave 92%kill in 0.05%dose and 100% kill in 0.1%dose.
