Abstract
The cowpea beetle, Callosobruchus maculatus (Fabricius.),is global, ,attacks seed of cowpeas and related legumes in stores. This investigation  was carried out in the plant protection department laboratory at Aswan University- Faculty of Agriculture and Natural Resources. .Three plants species belongs to two different families (Piperaceae, and Apiaceae), were used during these investigations against this weevil. The repellency effect of these plants was tested on the adults of C. maculatus which  infested faba bean seeds . Data on the percentage of repellency (PR΄s) of three (PE΄s) with five concentrations  showed that most PE΄s were strongly repellent against C. maculatus, The most effective PE΄s was Black Pepper fruits followed by Dill seeds and Cumin seeds. Data clear that acetone solvent  concentration 250 mg/l. air  recorded a highly significant numbers of repellent insects (65.56±8.68 and 68.89±7.29 ) in the first and fifth day after treated with black pepper and Dill , respectively. While cumin showed a highly percentage of insect ( 68.89 ±4.01) in  the same concentration (250 mg/l. air  ) after treated by petroleum solvent also in the fifth day of treated .This  present study,  revealed that these plants extracts enhanced its repellent efficacy to stored product insect, the cowpea beetle Callosobruchus maculatus (F.)
