Abstract
Mortality and antifeedant activity of two different neem-derived pesticides were investigated on larvae of Colorado potato beetle (Leptinotarsa decemlineata Say). In no-choice tests, mortality of larvae in- creased with increase in time period, meanwhile the feeding damage decreased with the increase of neem leaf extract concentration in contrast to NeemAzal T/S (1% azadirachtin) in which neither there was any signifi- cant difference in mortality nor on feeding damage. In the choice test, none of the treatments were lethal to the larvae tested. The larvae fed on the leaves irrespective of the treatment.
