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 کاملEvaluation of the potential of some local spices as stored grain protectants against the maize weevil Sitophilus zeamais Mots (Coleoptera: Curculionidae) UDO,
Five local spices (Piper guineense, Allium sativum, Afromomum melequata, Xylopia aethiopica and Tetrapleura tetraptera) were evaluated in the laboratory for their ability to protect stored maize against infestation by S. zeamais. Ground products of the spices were applied as direct admixtures at two concentration levels of 1% and 5% to assess for mortality, progeny emergence, damage and repelle...
متن کاملEfficacy of Some Botanical Extracts against Trogoderma granarium in Wheat Grains with Toxicity Evaluation
In an attempt to find alternative control methods for stored products insects, extracts of seven plant species (Cassia senna, Caesalpinia gilliesii, Thespesia populnea var. acutiloba, Chrysanthemum frutescens, Euonymus japonicus, Bauhinia purpurea, and Cassia fistula) were evaluated under laboratory conditions for their ability to protect wheat (Triticum spp.) grains against Trogoderma granariu...
متن کاملSurvival of Sitophilus oryzae (L.) on wheat treated with diatomaceous earth: impact of biological and environmental parameters on product efficacy
A series of experiments was conducted to evaluate the effects of temperature, relative humidity (r.h.), population density, concentration, exposure interval, and residual aging on susceptibility of Sitophilus oryzae (L.), the rice weevil, to diatomaceous earth (DE). In the first experiment, hard red winter wheat was treated with 300 ppm of the Protect-Itt formulation of DE, and 10, 20, or 30 1–...
