Diatomaceous Earth for Pest Control
نویسنده
چکیده
Least toxic physical and chemical solutions are often part of an IPM program. Various forms of amorphous silica are commonly used as part of this strategy. Diatomaceous earth and silica gel are used in various physical formulations with or without added pesticide. The type of silica and the formulation depend on the target pest. In this issue advantages and disadvantages of diatomaceous earth are discussed. In July the merits and uses of silica gel will be outlined.

Four diatomaceous earth formulations and one calcium carbonate formulation were evaluated in combination with high temperature as a control method for the adult stage of the red ̄our beetle, Tribolium castaneum (Herbst). At 348C, exposure to the insecticidal dusts for 15 or 30 min did not increase mortality relative to beetles not exposed to the dusts. However, at 508C, exposure increased morta...
متن کاملField trial of diatomaceous earth in cotton gin trash against the larger black flour beetle, Cynaeus angustus (Coleoptera: Tenebrionidae).
The larger black flour beetle, Cynaeus angustus (LeConte) (Coleoptera: Tenebrionidae), is an agricultural and home nuisance pest in North America. In the Southern High Plains of Texas, the larger black flour beetle is associated with cotton gin trash, by-products of cotton ginning that are field stored in large piles for economic reasons. Larger black flour beetle overwinter in gin trash piles ...
متن کاملSublethal Exposure to Diatomaceous Earth Increases Net Fecundity of Flour Beetles (Tribolium confusum) by Inhibiting Egg Cannibalism
Population regulation results from an interplay of numerous intrinsic and external factors, and for many insects cannibalism is such a factor. This study confirms a previously-reported observation that sublethal exposure to the fossilized remains of diatoms (i.e. diatomaceous earth) increases net fecundity (eggs produced minus eggs destroyed/day) of flour beetles, Tribolium confusum. The aim wa...
متن کاملEvaluation of methoprene alone and in combination with diatomaceous earth to control Rhyzopertha dominica (Coleoptera: Bostrichidae) on stored wheat
A series of experiments were conducted in which different formulations of the insect growth regulator methoprene were evaluated for control of Rhyzopertha dominica (F.), the lesser grain borer, a major internal insect pest of stored wheat. In the first test, application rates of 10-ppm R;S-methoprene (a racemic mixture of the R and S isomers of methoprene) and 1 and 5-ppm S-methoprene (S-isomer...
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?...
