Abstract Three concentrations (1.25, 2.5, and 5 × 10 7 spores ml −1 ) (of the biocontrol fungus Purpureocillium lilacinum (strain AUMC 10620) were tested on citrus nematode Tylenchulus semipenetrans under in vitro field conditions. Larvae eggs exposed to fungal for 24, 48, 72 h, findings recorded at each time point. These results compared with application of nematicide abamectin. Strain 10620 e...

This study examined the larvicidal effect of trunk-injected abamectin and emamectin benzoate against walnut husk fly (Rhagoletis completa Cresson, 1929). Walnut trees in two locations years were injected with pesticides at different concentrations. For toxicokinetic studies, active ingredient content was measured leaves, flowers, husks, kernels, using a UHPLC-MS/MS analytical method. The infest...

t g a 1 a c w ( a e c a e The compatibility of five insect growth regulators (IGRs), buprofezin, pyriproxyfen, fenoxycarb, pymetrozine, and kinoprene, were tested in the laboratory for compatibility with the whitefly parasitoid Eretmocerus eremicus Rose and Zolnerowich (Hymeoptera: Aphelinidae). The survivorship of adult paraitoids foraging on poinsettia leaves with residues 6, 4, and 96 h of a...

The article presents an assessment of the biological effectiveness biorational insectoacaricides based on abamectin and emamectin benzoate – metabolites soil actinomycetes, to protect grapes from pests. We studied new drugs: Mekar, ME (18 g/l abamectin) Mabet, EC against Schizotetranychus pruni ; Yunona, (50 benzoate), Emakleim, VRG benzoate) Proclame Fit, WDG (400 g/kg lufenuron + 50 emamectin...

The use insecticides still the choice farmers to control attacks due weak mitigation efforts an area. Continuous can increase resistance and resurgence BPH. purpose this study was determine level sensitivity BPH population pimetrozine insecticide...

Background: To assess the toxicity of environmental pollutants in fish, there are different physiological parameters including histology. This study aimed to investigate the effect of prebiotic dietary supplement on fish immune response after exposure to toxicant. Methods: The study was conducted in the Gorgan University of Agricultural and Natural Resources aquaculture Laboratory in 2017. Com...
