Persistence of stored-product insects in hidden refugia and their subsequent movement into stored commodities resulting in product infestation contributes to their pest status and represents a potential target for biological control agents. Entomopathogenic nematodes have not been previously tested against stored-product insects in environments such as empty grain bins or food processing and wa...

Due to the importance of insects present in storages, which cause a lot damage stored materials (cereals, seeds, dates and other materials), current study was proposed determine species spread Iraq. It showed 31 belonging 16 genera under eight families two orders. The specimens were collected from several storage spaces at regions Tribolium castaneum (Herbst, 1797) most abundant population comp...

essential oil extracted from the leaves of lemon verbena, lippia citriodora kunth (verbenaceae) was tested for fumigant toxicity in the laboratory against two stored-product insects tribolium confusum jacquelin du val and callosobruchus maculatus (f.). the chemical composition of the isolated oil was examined by gc-ms. the major compounds were citral (11.3%), limonene (10.6%), neral (7.9%), 4-p...

The recent recognition of psocids as a major concern in stored products and also the reemergence of heat treatment as a control tactic of stored-product insects led to the present investigation. The objectives of this study were to determine whether there are differences in heat shock tolerance of two species of stored-product psocids--Lepinotus reticulatus Enderlein (Trogiidae) and Liposcelis ...

Acoustic technology has been applied for many years in studies of insect communication and in the monitoring of calling-insect population levels, geographic distributions and species diversity, as well as in the detection of cryptic insects in soil, wood, container crops and stored products. Acoustic devices of various sizes and power levels have been used successfully to trap insect pests that...

the mediterranean flour moth, ephestia kuehniella zeller, is one of the major pests in stored products worldwide. several problems assossiated with the use of conventional insecticides have strongly demonstrated the need for applying alternative safe compounds such as insect growth regulators (igrs). in the present study, growth regulating activity and hematological effects of pyriproxifen and ...

762 between the tracheoles and the internal tissues. In resistant insects phosphine slowly reacts with some component of the membrane which retards its entry but may slowly oxidize it to hypophosphite. Since this site is not the toxic lesion no harm is done. In susceptible insects phosphine is transported unchanged into the internal tissues where it disrupts sensitive redox systems thus generat...
