Abtract: Interests in the permittivities of insects include data for radar applications in studying insect migration and for use in studies of dielectric heating for control of insects infesting cereal grains, wood products, and other materials. Sources of such data in the literature are identified, measurement data are presented, and dielectric properties data on insects are summarized in tabu...

A commercial formulation of the insect growth regulator methoprene was applied to wheat stored in small bins either alone or in combination with controlled aeration of the bins, to lower grain temperature for insect pest management of stored wheat. Grain temperatures were monitored and modified by a computer-controlled thermocouple system that also activated the aeration system at programmed se...

Sustainable and organic plant production uses natural products self-regulation processes occurring in the ecosystem. The awareness is growing demands of consumers are higher higher. One solution to use various methods, as an alternative pesticides. It also very important care for stored crops after harvesting especially using non-chemical methods. physical method protection consists treating ha...

Atmosphere modification by reducing oxygen or increasing carbon dioxide has been used widely in recent years as a chemical-free strategy for managing stored-product pest insects (Donahaye et al. 1996; Adler et al. 2000; Jayas and Jeyamkondan 2002). The red flour beetle, Tribolium castaneum (Herbst), being among the most problematic of stored-product insects, has been the subject of considerable...

The almond moth, Cadra cautella (Walker), is a common storage pest known to infest a wide range of dried plant materials, and it has been recorded from a warehouse in Florida during storage of dried passion-flower ( Passiflora incarnata L.) and dried saw palmetto berries Serenoa repens (Bartram) Small. Its status as a pest of stored saw palmetto was confirmed by trapping in a second warehouse u...

This study evaluated the toxicity and repellent activities of essential oils (EOs) against Sitophilus granarius (Linnaeus, 1758), both in vitro vivo conditions. The EOs obtained from Thymus pallescens No??. (Lamiaceae) Cymbopogon citratus Stapf. (Poaceae) were analyzed by GC-MS, revealed that carvacrol (56.64%) geraniol (20.8%) as respective major components. T. EO was found to be a more effect...

The first complete sequence of an insect genome was reported less than a decade ago (Adams et al. 2000). Fittingly, this was the genome of the fruit fly Drosophila melanogaster, a premier model organism for genetical and molecular studies of biological processes. Since then, the number of insect species for which genome sequencing efforts have been completed or are underway has grown substantia...

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 result...

Sanitation being an important component of chemical-free management of stored-products pests, the nutritional stress on insects that results from a clean environment may prove advantageous to the use of microbial controls. Dietary stress by food deprivation or suboptimal diet increased susceptibility of the red flour beetle, Tribolium castaneum (Herbst), larvae to Beauveria bassiana (Balsamo) V...
