The eastern spruce budworm (Choristoneura fumiferana) is one of the most destructive forest insect pests in Canada. Little is known about its intestinal microbiota, which could play a role in digestion, immune protection, communication and/or development. The present study was designed to provide a first characterization of the effects of rearing conditions on the taxonomic diversity and struct...

The phenological synchrony between the emergence of overwintering herbivorous insects and the budding of host plants is considered a crucial factor in the population dynamics of herbivores. However, the mechanisms driving the interactions between the host plant, herbivores, and their pathogens are often obscure. In the current study, an artificially induced phenological asynchrony was used to i...

ba ckground: mosquitoes are well known as vectors of several disease causing pathogens. the extensive use of synthetic insecticides in the mosquito control strategies resulted to the development of pesticide resistance and fos- tered environmental deterioration. hence in recent years plants become alternative source of mosquito control agents. the present study assessed the larvicidal and ovipo...

the rose sawfly, arge rosae linnaeus, is one of the most destructive pests of rose bushes in the north of iran. nowadays, many attempts have been made to reduce pesticide application by looking for new methods of pest control. a non chemical method for controlling insect pests including a. rosae can be achieved by using genetically engineered plants expressing carbohydrase inhibitors. therefore...

The biological actions of juvenile hormones are well studied; they regulate almost all aspects of an insect's life. However, the molecular actions of these hormones are not well understood. Recent studies in the red flour beetle, Tribolium castaneum, demonstrated the utility of this insect as a model system to study JH action. These studies confirmed that the bHLH-PAS family transcription facto...

objective(s):ethnopharmacological field surveys demonstrated that many plants, such as gentiana olivieri, helichrysum graveolens, helichrysum plicatum ssp. plicatum, juniperus oxycedrus ssp. oxycedrus, juniperus  communis var. saxatilis, viscum album (ssp. album, ssp. austriacum), are used as traditional medicine for diabetes in different regions of anatolia. the present study was designed to e...
