Abstract

Powders from five elite plant materials (nutmeg, Myristica fragrans; red hot chilli pepper, Capsicum annuum; ginger rhizome, Zingiber officinale; black pepper, Piper nigrum and alligator pepper, Aframomum melegueta) at 1.5 % w/w concentration were assessed against cowpea bruchid, Callosobruchus maculatus infestations on stored cowpea seeds under laboratory environmental conditions in three agro-ecological zones in Nigeria by members of the Research Group. The conventional synthetic insecticide, permethrin was included as standard check, while untreated seeds served as the control. Adult mortality, oviposition rate and adult emergence were the indices considered in the experiments. For the first three days of exposure, black pepper (P. nigrum) powder caused the highest percentage mortality (68.8, 78.0 and 83.8 % respectively) of the bruchid adults and differed significantly (P

五种药用植物对豇豆种子储存库中斑蛾的杀虫活性研究

五种优质植物原料(肉豆蔻，肉豆蔻;红辣椒，辣椒;姜根，生姜;课题组成员在尼日利亚3个农业生态区的实验室环境条件下，评价了黑胡椒、黑胡椒和鳄椒(Aframomum melegueta)在1.5% w/w浓度下对储存豇豆种子的豇豆病、斑点斑口蘑侵染效果。以常规合成杀虫剂氯菊酯为标准对照，未处理种子为对照。实验以成虫死亡率、产卵率和羽化率为主要指标。暴露前3 d，黑胡椒粉对野鼠成虫的死亡率最高，分别为68.8、78.0和83.8%，差异有统计学意义(P
