| Abstract: | The insecticidal activity of piper hancei against different stages of Brontispa longissima was studied. P. hancei extraction was detected against adult and 5rd instar larvae by stomach poisoning. The results showed the LC50 of 5rd instar larvae was 3.871 0 mg/mL, and that for the adult was 11.496 5 mg/mL. The eggs cytotoxicity was evaluated with contact poison. The LC50 for egg hatching was 4.768 5 mg/mL, and that from eggs hatched to instar larvae was 3.766 7 mg/ml. |
