Spinosad† (Dow Agrosciences) is a neurotoxic insecticide produced by fermentation of an actinomycete. Spinosad is classified as an environmentally and toxicologically reduced risk material and has been embraced by IPM practitioners as a biorational pesticide. We examined the available information on the impact of spinosad on natural enemies and classified mortality responses to spinosad using t...
Behavior of extinct organisms can be inferred only indirectly, but occasionally rare fossils document particular behaviors directly. Brood care, a remarkable behavior promoting the survival of the next generation, has evolved independently numerous times among animals including insects. However, fossil evidence of such a complex behavior is exceptionally scarce. Here, we report an ensign scale ...

Ants have long been renowned for their intimate mutualisms with trophobionts and plants and more recently appreciated for their widespread and diverse interactions with microbes. An open question in symbiosis research is the extent to which environmental influence, including the exchange of microbes between interacting macroorganisms, affects the composition and function of symbiotic microbial ...
Although chemical pesticides play a vital role in controlling the number of harmful insects, they also contribute to accelerate pollution soil, air and water. Due frequent use, insects become resistant active ingredients very quickly; destroy natural enemies pests, have effect on humans. Accordingly, application biological protection, that is, use living organisms (predators parasites) plant pr...
Climate warming is considered to be among the most serious of anthropogenic stresses environment, because it not only has direct effects on biodiversity, but also exacerbates harmful other human-mediated threats. The associated consequences are potentially severe, particularly in terms threats species preservation, as well preservation an array ecosystem services provided by biodiversity. Among...
On earth, insects are by far the most diverse group of organisms found on almost all land surfaces and throughout the ocean, this is why they are among the most familiar creatures coming in human’s contact. So, larger the numbers of insects, there is greater the possibility of severe annoyance to human. The objective of this guideline in to help homeowners for identifying and understanding some...
