Entomocidal effects of beech apricot, Labramia bojeri, seed extract on a soybean pest, the velvetbean moth, Anticarsia gemmatalis, and its enzymatic activity.
J Insect Sci. 2014 Feb 26; 14:27.JI

Abstract

The effects of the beech apricot, Labramia bojeri A. de Candolle (Sapotales: Sapotaceae), seed aqueous extract on the larval development of the velvetbean moth, Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae), was evaluated. The extract inhibited larval development, pupal weight, and survival and emergence of adults. Digestive proteolytic activity in larval midgut and feces extracts was determined. Larvae fed 10 g/L of the aqueous extract showed a significant reduction in trypsin activity (~64%), when compared with control larvae. Trypsin and chymotrypsin activities were also detected in fecal material in aqueous-extract-fed larvae, with about ~4.5 times more trypsin activity than the controls. The results from dietary utilization experiments with A. gemmatalis larvae showed a reduction in the efficiency of conversion of ingested food and digested food and an increase in approximate digestibility and metabolic cost. The effect of the extract suggests the potential use of L. bojeri seeds to inhibit the development of A. gemmatalis via oral exposure. The L. bojeri extract can be an alternative to other methods of control.
