Abstract

Histological studies revealed disruption of the cellular structures of the H. armigera larval midgut, fed on methanol leaf extract of A. annua at 2 percent concentration. The most characteristic effect was disruption of peritrophic membrane in the midgut of larvae. Overall tissue destruction leaving gaps and lacunae at various layers was observed.
