Efficacy of thiamethoxam (Cruiser) and imidacloprid (Gaucho) were evaluated as seed treatments for controlling European corn borer, Ostrinia nubilalis (Hübner) and Indianmeal moth, Plodia interpunctella (Hübner) larvae in stored grain. At approximately 22-26 degrees C, all fifth instar European corn borers died after two or 4 d of exposure to corn treated with 250 and 500 ppm thiamethoxam, resp...
Efficacy of methoprene applied at different temperatures and rates to surface substrates to control eggs and fifth instars of Plodia interpunctella Hubner Methoprene is an insecticide that is used in pest management programs for stored grains, and works by inhibiting the molting process of insect larvae. Methoprene is effective on stored-product beetles, but there are comparatively fewer data r...
A proteinaceous trypsin inhibitor was purified from Crotalaria pallida seeds by ammonium sulfate precipitation, affinity chromatography on immobilized trypsin–Sepharose and TCA precipitation. The trypsin inhibitor, named CpaTI, had Mr of 32.5 kDa as determined by SDS-PAGE and was composed of two subunits with 27.7 and 5.6 kDa linked by disulfide bridges. CpaTI was stable at 50 °C and lost 40% o...
Pest control in the agricultural fields, a major concern globally, is currently achieved through chemical or biological methods. Chemical methods, which leave toxic residue in the produce, are less preferred than biological methods. Venoms injected by stings of various wasps that kill the pest is considered as the examples of the biological method. Although several studies have investigated the...
We propose a treatment strategy combining an initial disinfestation treatment with one of three protective treatments as an alternative for chemical fumigation of almonds and raisins for control of postharvest insect populations. Initial disinfestation treatments using low oxygen controlled atmosphere (0.4% O2) were designed to disinfest product of field populations of pyralid moths; navel oran...
functional response of trichogramma brassicae bez. to different densities of eggs of two host species anagasta kuehniella zell. and plodia interpunctella hub. was studied under laboratory conditions (24±1°c, 65±10% rh and 16: 8 l:d photoperiodism). one day old eggs of either host were offered to individual females of t.brassicae in densities 2, 4, 8, 16, 32, 64 and 128 respectively in 21, 15, 1...
