    of early and late instar stages of H. puera to determine the larval morality after 24 and 48 h. Results showed that the P. hysterophorus extract elicited 20, 80 and 60% H. puera early instar larvae mortalitymortalitySubject Category: Miscellaneous

    in 24 h at 1.0, 2.0 and 5.0% concentrations, respectively, and 100% mortality in 48 h at all concentrations. The late instar larva of H. puera showed differential mortality rates at 24 and 48 h in the P. hysterophorus concentrations of 1.0, 2.0 and 5.0%, where the highest mortality (60%) was recorded at 48 h in the 1.0% concentration. Among the different concentrations tested, a maximum of 60% mortality was recorded in the 1.0% O. tenuiflorum concentration and a minimum of 30% mortality occurred at both 2.0 and 5.0% concentrations at the early period of the study, whereas at 48 h, no mortality was observed.
