The Fumigation Bioactivities of Three Kinds of Plant Extracts on Four Species of Important Storedgrain Insects
摘要：
Plant extracts were extracted by Soxhlet extractions with anhydrous diethyl ether from Citrus suavissima Tanaka,Ailanthus altissima L. and Capsicumfrutescensp L.,and their fumigation bioactivities on Sitophilus oryzae, Oryzaephilus surinamensis, Tribolium castaneum adults and Liposcelis paeta nymphae at a specific concentration of 1:15 of plant extract :acetone by volume were detailedly investigated in the paper. The results showed that all of the plant extracts have significant fumigant activities on O. surinamensis adults and weak fumigant activities on Sitophilus oryzae, Tribolium castaneum adults and Liposcelis paeta nymphae. The highest corrected mortality of O. surinamensis adults reached more than 99%.
