Evaluation of Inert Dusts on Surface Applications and Factors That Maximize Their Insecticidal Efficacy

We evaluated formulations of diatomaceous earth and zeolite originated from natural deposits Greece as insecticides in concrete steel surfaces for the control three major beetle species stored products: Sitophilus oryzae (L.) (Coleoptera: Curculionidae), Rhyzopertha dominica (F.) Bostrychidae) Tribolium confusum Jacquelin du Val Tenebrionidae). The were tested dusts at 0.5 or 1 g/m2. Our results indicated that, most cases tested, inert materials caused 100% adult mortality all species, even lowest dose, after 7 days exposure. At same time, there no considerable differences insecticidal effect between surfaces. Among R. was susceptible, followed by S. T. confusum. indicate that resource-based silicaceous could be used with success product protection against insects dose rates are comparable other commercially available material-based formulations.
