influence of grain type on the susceptibility of tribolium confusum adults to three diatomaceous earth formulations
insecticidal efficacy of three diatomaceous earth (de) formulations, debbm, dea and f2 was evaluated on three different wheat cultivars, chamran, verinak and behrang, against tribolium confusum jacqueline du val. des were applied at the rates of 100, 200 and 300 mg/kg. bioassays were carried out on wheat at 27 ± 1 °cand 55 ± 5% rh in continuous darkness. mortality of adults was counted after 2,...
متن کاملInsecticidal efficacy of diatomaceous earth against Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae)
Laboratory bioassays were carried out to evaluate the insecticidal efficacy of SilicoSec? against 7 - 14 day old adults, old and young larvae of Tribolium castaneum (Herbst) with the mean ? SE (n = 30) weight of 3.4 ? 0.1 and 0.6 ? 0.1 mg, respectively at 27?C and 55 ? 5% RH. Wheat treated with four dose rates of SilicoSec? and untreated wheat served as a control with three replications. Adult?...
متن کاملEfficacy of diatomaceous earth formulations admixed with grain against populations of Tribolium castaneum
The efficacy of diatomaceous earth (DE) to control stored-products Coleoptera on stored grain was examined against several populations of the red flour beetle, Tribolium castaneum (Herbst). Four commercially available DE formulations were tested: INSECTO, Perma-GuardTM, Protect-It and the diatomite used for the production of Dryacide, each at six concentrations (100-1000 ppm). A great variation...
متن کاملDistribution and efficacy of pyrethrin aerosol to control Tribolium confusum (Coleoptera: Tenebrionidae) in food storage facilities
A field test was conducted whereby adult Tribolium confusum (du Val), the confused flour beetle, were exposed in Petri dishes lined with filter paper and containing 0–2000mg of flour, to a pyrethrin–CO2 aerosol inside an empty warehouse. Applications were made according to label directions, and beetles were exposed to the aerosol for 2 h. After exposure, knockdown was assessed, and beetles were...
متن کاملEfficacy of a volatile formulation of hydroprene (Pointsourcet) to control Tribolium castaneum and Tribolium confusum (Coleoptera: Tenebrionidae)
Threeand 4-week-old Tribolium castaneum (Herbst), the red flour beetle, and Tribolium confusum (du Val), the confused flour beetle, were exposed at five different temperature–relative humidity (r.h.) combinations to a volatile formulation of the insect growth regulator (IGR) hydroprene (called Pointsourcet). Typical effects associated with IGR exposure, such as arrested larval growth, morpholog...
