“…Similar results were also reported by Arthur (2000) and Vayias and Athanassiou (2004) regarding the red flour beetle, Tribolium castaneum (Herbst), and the confused flour beetle, Tribolium confusum Jacquelin du Val. The reports on the influence of rh on DE efficacy are in agreement with the fact that DE formulations are not effective at high rh levels, and this trend is evident for all beetle species examined so far (Le Patourel, 1986;Aldryhim, 1990Aldryhim, , 1993Arthur, 2000;Fields and Korunic, 2000;Vayias and Athanassiou, 2004). Low rh values cause a more rapid desiccation, which is the mode of action of DE (Subramanyam and Roesli, 2000).…”

“…DE formulations are usually applied directly to the product with almost the same technology as traditional residual insecticides (Subramanyam and Roesli, 2000), so there is practically no need for expensive changes in application machinery in stored-grain facilities. Several studies have shown that DE formulations are effective against a wide range of species, but researchers underline the fact that DE efficacy can be affected by several biotic or abiotic factors; e.g., temperature (Aldryhim, 1990(Aldryhim, , 1993Arthur, 2000Arthur, , 2002Fields and Korunic, 2000;Athanassiou et al, 2005), moisture content or relative humidity (Arthur, 2000(Arthur, , 2002Fields and Korunic, 2000;Vayias and Athanassiou, 2004), and type of product (Athanassiou et al, 2003). Recent laboratory experiments revealed the significant effect of insect strain (Rigaux et al, 2001) and stage (Mewis and Ulrichs, 2001;Vayias and Athanassiou, 2004).…”

The insecticidal efficacy of the diatomaceous earth formulation SilicoSec ® (Biofa GmbH) against adults of the rice weevil, Sitophilus oryzae, was evaluated in laboratory experiments on stored wheat. Bioassays were conducted at three temperature levels, 22, 27 and 30°C, two relative humidity (rh) levels, 55 and 65%, and four dose rates, 0.25, 0.5, 1 and 1.5 g of SilicoSec ® /kg of wheat. Three different aged-adult groups, 1, 2 and 7 d-old, were exposed. The mortality of exposed adults increased with the exposure interval and dose rate. Also, the increase of temperature increased S. oryzae mortality in all exposure intervals examined. The increase of rh from 55 to 65% caused a significant decrease in S. oryzae mortality. The age of the exposed individuals did not have a direct effect on SilicoSec ® efficacy.

“…The efficacy of DE is significantly reduced by increasing the moisture content of DE to above 8-10%. When particles are filled with a film of water and the holes and pores are completely saturated with water, DE loses its sorption ability for wax and its insecticidal efficacy is lost entirely (Ebeling, 1971;Le Patourel, 1986; Le Patourel and Zhou, 1990; Aldryhim, 1990Aldryhim, , 1993Quarles, 1992; Golob, 1997; Korunić, 1997;Fields and Korunić, 2000).…”

SUMMARYThe efficacy of diatomaceous earth (DE) formulations against insect pests is greatly influenced by environmental conditions. It is effective only under dry conditions and becomes wholly ineffective if it is wet. High air relative humidity and especially rain greatly reduce or completely destroy the efficacy of DE when used outdoors. Furthermore, depending on the insect species and commodity treated, DE takes from one to several days to kill insects, even in a dry environment. Because of these factors, DE is in limited use outdoors, especially in regions with a high precipitation. The main uses of DE are for the protection of stored agricultural products against insect infestation, in food industry for structural treatment and for indoor use against some household insects living in a dry environment. The mode of DEs action against insects, the effect of humidity and moisture on DE efficacy, brief overview of the research of DE use in stored grain protection and attempts to overcome DE limitations with combined use of DE and other reduced-risk methods with the insecticide activity for direct mixing with grains are discussed in this article.

Laboratory bioassays were conducted to evaluate the insecticidal effect of diatomaceous earth (DE), SilicoSec against Callosobruchus maculatus (F.), Rhyzopertha dominica (F.), Sitophilus zeamais (Motschulsky), and Tribolium castaneum (Herbst) in cowpea, maize and wheat, at 25-32 °C and 54-68% relative humidity (r.h.). SilicoSec was applied at rates: 0 (untreated control) 250, 500, 750 and 1,000 mg/kg of commodity. Adult mortality was measured after 3 to14 days of exposure. Progeny production was assessed after 40 or 56 days. The tested species varied in sensitivity to SilicoSec, with S. zeamais being most susceptible, but no significant differences in mortality levels observed between R. dominica, C. maculatus or T. castaneum after three days of exposure. After 5 days of exposure, all C. maculates adults died on cowpea treated at 1,000 mg/kg. Similarly, after 14 days of exposure all adults of the other species died on grains treated at 1,000 mg/kg, and were ranked in decreasing order of susceptibility S. zeamais > T. castaneum > R. dominica. SilicoSec treatments suppressed progeny production (30 to 100%) in all the tested species. The implications of these findings to DE-based control strategy are discussed.
