Aims: The main objective of the present study was to investigate the larvicidal effect of some biological control agents like Beauveria bassiana and Bacillus thuringiensis var. israelensis (B.t.i.) and some natural control agents as Diflubenzuron, Azadirachtin and Emamectin benzoate on Culex pipiens mosquito. The toxicity of binary mixtures of these control agents was also assessed. Methodology...

Effective methods are needed to protect ash trees (Fraxinus spp.) from emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), an invasive buprestid that has killed millions of North American ash (Fraxinus spp.) trees. We randomly assigned 175 ash trees (11.5-48.1 cm in diameter) in 25 blocks located in three study sites in Michigan to one of seven insecticide treatments in ...

Emamectin benzoate, the active ingredient in SLICE®, targets the nervous system of arthropods. Ingestion of high doses causes ovigerous American lobsters Homarus americanus to molt before their eggs hatch. To determine the effect of repeated exposure to doses at or below the noobserved-effect level (NOEL) of a single exposure (NOEL: 0.12 μg g–1), ovigerous lobsters were given either a single do...

Ž . Ž . Atlantic salmon weight range 289–484 g and rainbow trout weight range 166–387 g , held in seawater, were fed medicated diets containing graded levels of emamectin benzoate for 7 days. y1 y1 Ž Nominal dose rates were 0, 100, 250 and 500 mg kg body weight day equivalent to 0, 2, 5 . and 10 times recommended dose rate for treatment of sea lice . Fish were observed for a further 7 days to d...

Chile is the second largest global producer of farmed salmon. The growth salmon production has not been free environmental challenges, such as increasing use pesticides to control parasitic load sea lice Caligus rogercresseyi. lack specificity can potentially affect non-target organisms, well structure and functioning aquatic ecosystems. aim this study, was understand effect on natural microbia...

The effect of twelve different groups insecticides on diversity major predators (insects and spiders) during active tillering bootleaf stage rice crop was evaluated in West Bengal. results showed that spinosad, emamectin benzoate, sulfoxaflor pymetrozine were highly safe while buprofezin, imidacloprid, indoxacarb chlorantraniliprole moderately so. like lambdacyhalothrin, fipronil chlorpyriphos ...
