Laboratory evaluation of the toxic properties of forest anchomanes, Anchomanes difformis against pulse beetle Callosobruchus maculatus (Coleoptera: Bruchidae)
Insect Science 13 (1), 25-29
Abstract: Laboratory experiments were carried out to investigate the efficacy of crude stem extracts of forest anchomanes, Anchomanes difformis (P. Beauv.) a plant occurring in West African forests, against the pulse beetle Callosobruchus maculatus (Fabricius). Crude stem extracts at 3% concentration showed high contact toxicity to adult beetles within 24 h after application, while it was moderately toxic to the beetles at the lowest (1%) concentration. At the highest application rate, the plant extract provided good protection to grains stored for 90 days. Grain viability and water absorption capacity were not affected by treatments with ethanol extracts of A. difformis. The significance of these findings is discussed in relation to biopesticide-means of controlling cowpea bruchids.
