Over the years, extensive use of commercially available synthetic pesticides against phytophagous insects has led to their bioaccumulation in the environment causing increased resistance and reduction in soil biodiversity. Further, 90% of the applied pesticides enter the various environmental resources as a result of run-off, exposing the farmers as well as consumers of the agricultural produce...

In this chapter we argue that while pesticides can be harmful to pollinators, when they are used in an integrated pest and pollinator management (IPPM) context, both pest management and pollinator protection may be achieved. Our growing knowledge of the impacts of pesticides on honey bees as well as bumble bees and solitary bees allows us to use the latitude we have in pest management including...

Recent advances in paint technology have guided the development of novel “ready-to-use” paint formulations in which microencapsulated insecticides, or active ingredients (AIs), are embedded in the paint matrix and gradually released on the surface of the dried paint [1]. It is argued that the slow-release mechanisms enable uniform AI surface concentrations with prolonged residual effect, as com...

Abstract The volatile organic compounds (VOCs) 1-octen-3-ol and 3-octanone produced by the entomopathogenic fungus Metarhizium brunneum are known to have pesticidal properties at high doses against a range of invertebrate pests. Very little is about their behavior-modifying (semiochemical) properties. This study focused on investigating behavioral responses three subterranean crop pests, wirewo...

Two researchers from the University of Sherbrooke Canada (1) recently published an article finding the presence of the pesticidal protein Cry1ab GMO in the blood for almost all pregnant women and their fetuses, and non-pregnant women. It is assumed that this protein appears in the blood after dietary intake of GM-maize, which is the main source in Canada. The authors also describe the absorptio...
