A 17-month-old male King Charles cavalier was presented with acute onset of generalized body tremors and facial twitching after being exposed to 2 different compounds of the pyrethrins/pyrethroids group and imidacloprid. Bifenthrin toxicity was confirmed by gas chromatography mass spectrometry. Initial therapy consisted of diazepam, metacarbamol and IV fluids, followed by general anesthesia wit...

Information on dissipation kinetics of pesticides in food crops and other plants is a key aspect in current risk and impact assessment practice. This is because human exposure to pesticides is predominantly caused by residues in agricultural crops grown for human and animal consumption. However, modeling dissipation of pesticides in plants is highly uncertain and therefore strongly relies on ex...

In the Caribbean, insecticide resistance is widely developed in Aedes aegypti and represents a serious obstacle for dengue vector control. The efficacy of pyrethroid and organophosphate ultra-low volume space sprays was investigated in Martinique where Ae. aegypti has been shown to be resistant to conventional insecticides. In the laboratory, a wild-field caught population showed high levels of...

The Cytogenetic effects of Cypermethrin a synthetic pyrithroid insecticide was investigated on human lymphocytes cultured in-vitro. Utilizing the trypan blue dye exclusion technique assay the LC50 of cypermethrin was found to be 36 uM. Based on LC50 value, cypermethrin was found to be low toxic to lymphocyte culture. Cypermethrin showed an increase in the frequency of chromosomal aberrations an...

Synthetic Pyrethroids are synthetic analogs of naturally occurring pyrethrins, found in extract from Chrysanthemum flowers. They were launched as a replacement of highly toxic class of pesticides like DDT and Organophosphates in 1980s. Major success of pyrethroids lies in the low toxicity of them towards mammals as well as humans and due to which they have wide range of applications right from ...

The American leafhopper Erasmoneura vulnerata, detected in Europe the early 2000s, has recently become a pest North-Italian vineyards. Infestations were recorded organic and conventional vineyards despite application of insecticides targeting other pests. vulnerata completes three generations per year, second generation is frequently associated with large populations. selection appropriate acti...
