ABSTRACT
Ethanolic extract from flowers of Verbascum cheiranthifolium Boiss. (Scrophulariaceae) was examined for its effect on mortality and progeny production against adults of Sitophilus oryzae (L.) and Tribolium castaneum (Herbst.). The insecticide was applied at five dose rates, which 0.25, 0.5, 1.0, 2.0 and 3% (w/v). Adults of the above-mentioned species were exposed to the treated wheat at 25°C and 65% RH and mortality was assessed after 24 and 48 h, 7, 14 and 21 day of exposure. Then all adults were removed and the treated substrate remained at the same conditions for an additional 45 day after this interval, the commodity was checked for progeny production. For two species mortality increased with the increase of dose and exposure interval. Results indicate that S. oryzae was more sensitive than T. castaneum. In case of S. oryzae mortality was 100% after 21 day of exposure at the highest dose rate. For two species, complete suppression of the progeny production was observed in the treated wheat than in the untreated wheat even in the lowest dose rate. Therefore, this botanical material can be used for protection of stored Wheat from infestations of stored-product insect pests.
