以0.0%(对照)2.5%、5.0%、12.5%和25.5%(w/w)的4种植物粉添加到20g小麦籽粒中，研究了4种植物粉对玉米象甲成虫死亡和羽化的影响。用处理后24~96h的死亡率、籽粒失重率和子代第一代(F1)的受害程度来评价植物粉保护小麦籽粒的能力。结果表明，在所试验的浓度范围内，野生稻和野生稻的保护力最强，而柯拉和油茶的保护性较差。这些植物粉在贮藏3个月后没有对种子的生活力产生不利影响，这表明用野生稻、野生稻、科拉和油茶处理的种子适合食用和种植储备。玉米象种子粉是防治玉米象的一种很好的替代药剂，而印度玉米象种子粉对玉米象的防治效果已被许多前人的研究成果所证实。

This research reported the effect of four plant powders including Azadirachta india, Alstonia boonei, Garcina kola and Moringa oleifera on the mortality adults and emergence of maize weevil (Sitophilus zeamais) on stored wheat grains. The powders were incorporated into 20 g of wheat grains at 0.0% (control) 2.5, 5.0, 12.5 and 25.5% (w/w). The ability of the plants powders to protect wheat grains were assessed in terms of mortality rates after 24 to 96 h of post treatment, percentage grain weight loss and damage after the first filial generation (F1). The results indicated that A. indica and A. boonei provide the highest protection of the treated grains. G. kola and M. oleifera were not good enough protectants at the concentrations tested. These plants powders did not adversely affect seed viability after three months of storage, suggesting that seeds treated with A. indica, A. boonei, G. kola and M. oleifera are suitable for consumption and planting stock. Seed powders of A. boonei can be used as a good alternative to pesticides against S. zeamais in addition with that of A. indica which effects are well established by many former works.
