The insecticidal effect of diatomaceous earth against adults and nymphs of Blattella germanica.
OBJECTIVE To evaluate the insecticidal effect of diatomaceous earth (DE) against adults and nymphs of Blattella germanica. METHODS This cross sectional study has been done on the laboratory strain of German cockroaches. Two stages, nymph and adult, were exposed to six dose rates of the DE, 2.5, 5, 10, 15, 20 and 25 g/m(2), at 24, 48 and 72 h exposure period. Mortality (number of dead cockroac...

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.

Efficacy was assessed on wheat and maize at three dosages of spinosad dust formulation (corresponding to 0.0625, 0.1875 and 0.625ppm of active ingredient [AI] for S. oryzae and to 0.1875, 0.625 and 1.25 ppm of AI for T. confusum), alone or combined with SilicoSec at 150ppm for S. oryzae and 250 ppm for T. confusum. The mortality of S. oryzae exposed for 14d on...

In the oviparous German cockroach, Blattella germanica, long-chain hydrocarbons are produced by oenocytes within the abdominal integument and are transported by a blood lipoprotein, lipophorin, both to the cuticular surface and into vitellogenic oocytes....
