原始语种摘要: The insecticidal efficacy of Acacia auriculiformis oil extract in the laboratory at ambient temperature of 28±3oC and 75±5% relative humidity. The oil of the plant was made by cold extract using ethanol as solvent. The oil was tested at 1, 2, 3, 4 and 5% concentration per 20 g of cowpea. The mortality of the insect was observed at 24, 48, 72 and 96 h post treatment. The oviposition and adult emergence of the insect as well as the seed damage, seed weight loss and weevil perforation index were observed. The result obtained showed that only 5% concentration of the oil achieved above 50% mortality of the insect at 96 h post treatment and its effect was significantly different from other concentrations and the controls. 4.91% of the oil was required to achieve 50% mortality of the...
