EVALUATION OF SELECTED INSECTICIDES AS SEED PROTECTANTS AGAINST THE MAIZE WEEVIL, (Sitophilus zeamais M
An investigation was carried out to evaluate the relative toxicity of selected newer insecticides viz., deltamethrin, spinosad, abamectin and emamectin benzoate in comparision with the organophosporus insecticide malathion to the maize weevil, Sitophilus zeamais Motschulsky, in an attempt to find out a safer and effective seed protectant. The LC50 values based on bioassay studies indicated that...
متن کاملEfficacy of Selected Insecticides Applied to Hybrid Rice Seed
Hybrid rice and insecticide seed treatments targeting rice water weevil, Lissorhoptrus oryzophilus Kuschel, have altered the landscape of rice production. The effect of reduced seeding rates on seed treatment efficacy in hybrid rice has not been studied. During 2011 and 2012, an experiment was conducted at seven locations to determine the relationship between low seeding rates used in hybrid ri...
متن کاملManagement of Egyptian Alfalfa Weevil and Protection of Yields with Selected Insecticides
The Egyptian alfalfa weevil (alfalfa weevil in some areas) during most years is the most severe insect pest of alfalfa in California. These pests feed on alfalfa leaflets and stems, reducing hay yields. Several insecticides provide acceptable control of this pest. Historically, product choice has been driven by efficacy on the pest, cost, presence of other pests, i.e., aphids, days before harve...
متن کاملPhytochemical residue profiles in rice grains fumigated with essential oils for the control of rice weevil
In the present study, we investigated the fumigant potential of five edible essential oils (EOs) against Sitophilus oryzae and their phytochemical residues in treated grains. Among the tested EOs, peppermint oil proved significantly effective (P ≤ 0.05) on S.oryzae at 400 μl/L air concentration, inducing 83 and 100% mortalities in with-food and without-food conditions respectively over 72 h exp...
متن کاملEffect of Depth of Flooding on the Rice Water Weevil, Lissorhoptrus oryzophilus, and Yield of Rice
The rice water weevil, Lissorhoptrus oryzophilus (Kuschel) (Coleoptera: Curculionidae), is a semi-aquatic pest of rice and is the most destructive insect pest of rice in the United States. Adults oviposit after floods are established, and greenhouse studies have shown that plants exposed to deep floods have more eggs oviposited in leaf sheaths than plants exposed to a shallow flood. Experiments...
