| Abstract | ||||
| Broad bean seeds are important main source of dietary proteins and vulnerable to heavy storage infestation by Calbsobruchus inaculatus (F.) and C. chinensis (L.). Four botanical seed powders (Black cumin, Datum, Fenugreek and Termes), dusts of Neemazal 10 % as botanical insecticide, Malathion 1% D and Sevin 85 % WP as synthetic pesticides (for comparison) were screened as possible protectants of stored faba bean seeds. Effectiveness was depending on type and concentration of tested powder and insect species, which a reduction of both oviposition and adult emergence increased with increase of the admixture rate. Neemazal and Termes seed powder were the most effective, while fenugreek was the least effective on both insects. C. maculafus was more sensitive than C. chinensis to the tested powders. Inhibition rate (IR %) as amount of protection increased with increasing of the mixing rate. The tested powders, thus gave satisfactory protection at 8% of faba bean seeds compared with untreated control. | ||||
