Insecticidal 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 کاملDiatomaceous earth increases the efficacy of Beauveria bassiana against Tribolium castaneum larvae and increases conidia attachment.
This research tested the suppressive ability of Beauveria bassiana (Balsamo) Vuillemin alone and in combination with diatomaceous earth against the red flour beetle, Tribolium castaneum (Herbst). Adults did not show a dose response to B. bassiana, and the addition of diatomaceous earth (DE) did not result in a significant increase in mortality. Against larvae, however, DE at 190 mg/kg grain enh...

متن کاملinfluence 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,...
