Abstract:

Experiments were conducted inside metal drums situated in the breeding room at 26 ±2°C and 60 ±5 % RH. to evaluate the impact of the acetone extracts of, piَnciana seed Delonix regia, cinnamon strip bark Cinnamonum zeylanicum, colves flowering buds Syzygium aromatcum, mustard seeds Brassica alba and radish seeds Raphanus sativus at 1% w/w alone. 16 ppm malathion alone and under modified atmosphere (MA) of ca. 25% C02-compared with untreated grains - َn the populations of the rice weevil Sitophilus oryzae (L.), the lesser grain borer Rhizopertha dominica (F.) and the red flour beetle Tribolium castaneum (Herbst), as well as the loss in weight of maize grains stored for one year. The results showed that exposure of the three insect species to the extracts of cloves, mustard, radish and malathion under the MA of 25% Co2 showed a total inhibition of the insect populations during the 12 months storage periods of maize grains. Also, it was found that grain treatment with cloves extract alone showed complete inhibition of the three insect species populations and also lower rates in grain losses during the 12 months storage period, while cىnnainon extract or mustard seeds extract alone gave lower reduction rates in the grain losses and proved to be ineffective in reducing maize grain losses during the test period. Meanwhile. T castaneum adults were less sensitive to all treatments than S. oryzae and R. dominica adults.
