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...

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...

Two hundred sediment samples were collected and their toxicity evaluated to aquatic species in a previous study in the agriculturally dominated Central Valley of California, United States. Pyrethroid insecticides were the main contributors to the observed toxicity. However, mortality in approximately one third of the toxic samples could not be explained solely by the presence of pyrethroids in ...

The two-spotted spider mite, Tetranychus urticae, is an important pest of horticultural crops worldwide and has developed resistance against multiple kinds pesticides. To date, information on the to pesticides inadequate for T. urticae populations in Hainan, south China. In current study, we determined seven five field that were collected cucurbit Hainan 2021. results showed high extremely abam...

İki noktalı kırmızı örümcek, Tetranychus urticae Koch (Acari: Tetranychidae) elma bahçelerinde ekonomik kayıp oluşturan önemli zararlılardan birsidir. Kısa süreli biyolojileri nedeniyle kullanılan akarisitlere çok kısa sürede direnç geliştirmektedirler. Bu nedenle etkili bir kimyasal mücadele için T. popülasyonlarının gösterdikleri duyarlılık düzeyleri periyodik olarak izlenmelidir. çalışmada, ...

INTRODUCTION Honeybees are constantly exposed to a wide range of vital and non-vital pressures that may interact with each other and affect the health or survival of the insects. Pesticides are the main danger for the insects, and they subsequently have impacts on human and environmental health. METHODS Field research was conducted in the apiary of Hada Al Sham Research Station, where the wor...

Fenitrothion, endosulfan and abamectin are insecticides that affect various organs in humans and animals. The present study was conducted to investigate their cytotoxicity in isolated male rat hepatocytes. The study suggests that incubation of hepatocytes with 10 or 100 microM of each insecticide for 2h significantly decreased the cell viability. Increased leakage percentage of lactate dehydrog...

The high level of resistance to the macrocyclic lactones has encouraged the search for strategies to optimize their potential as antiparasitic agents. There is a need for pharmaco-parasitological studies addressing the kinetic-dynamic differences between various macrocyclic lactones under standardized in vivo conditions. The current work evaluated the relationship among systemic drug exposure, ...

The effects of various insecticides on the fluidity of mitochondrial membranes and cross-resistance were investigated in the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae) using strains that were both resistant and susceptible to avermectin. The resistant strain of P. xylostella, AV-R, developed 1078-fold resistance to avermetins with a high level of cross-resistance to t...
