Pesticides are commonly used to control weeds, diseases, and pests in soybean crops, although natural enemies also key components of integrated pest management programs protecting from pests. The predatory mite Neoseiulus idaeus Denmark & Muma is found soybeans associated with tetranychid mites. We determined the compatibility some pesticides Brazilian fields N. on basis their lethal sub-le...

The parasitoid Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) is often released to manage lepidopteran pests in cotton crops. However, growers rely on multiple insecticide applications pests. A harmonious integration of control tactics required for proper pest management, and the use selective insecticides (i.e., those promoting effective while causing little impact natural enemi...

Growth of the aquaculture industry has triggered the need for research into the potential environmental impact of chemicals used by salmon farms to control diseases. In this study, the antiparasitic pesticides emamectin benzoate (EB), diflubenzuron (DI), teflubenzuron (TE), and cypermethrin (CP) were measured in sediments near salmon cages in southern Chile. Concentrations for EB were between 2...

To achieve a sustainable salmonid aquaculture industry, the environmental impacts of chemicals used to treat sea lice (Caligidae) infestations need be considered. Our ability assess risks associated with these treatments in relation human and wildlife health is limited by lack information on their concentrations marine coastal environments. Diflubenzuron teflubenzuron are chitin synthesis inhib...

The dynamics of incurred pesticide residues in apples, variety Melrose, was monitored during their cold storage at 1–3 C for 5 months. Of 21 active ingredients contained in pesticide preparations applied within four experimental pre-harvest regimes, only six fungicides (captan, cyprodinyl, dodine, pyrimethanil, tebuconazole, tolyfluanid) and one insecticide (phosalone) were detected at the time...

Toxicity of 17 commonly used insecticides used to control diamondback moth, Plutella xylostella (L.) was evaluated against adults of Cotesia plutellae Kurdjumov. The insecticide concentrations studied were equivalent to those recommended in the field. Adults of the parasitoid were released into exposure kits with fresh dry insecticide film for 24 hours, at which time mortalities were noted. The...
