A sample of Aedes aegypti (L.) from Santiago de Cuba, Cuba, with a high level of temephos resistance (19.58x at the 50% lethal concentration [LC50]), was subjected to temephos selection to evaluate the utility of this organophosphate insecticide for mosquito control. High resistance developed after six generations of selection (200.00x). Little or no cross-resistance was observed to the organop...

Studies on some enzymes involved in insecticide resistance in fenitrothion-resistant and susceptible strains of Musca domestica L. 2002. Prevalence of ectoparasites in a population of feral cats from north central Florida during the summer. Development of an automatic measuring system for recording the number of tail swishing against pest flies in grazing cattle. evaluation of the application o...

The use of chemical pesticides to manage locust populations in natural ecosystems is likely impact non-target arthropods and their predators. However, the relative effects different control applications on Australian birds are unknown. Aerial fipronil fenitrothion examples two used semiarid Australia. To test impacts fauna, were applied replicate sites using aerial ultra-low-volume application ...

Two immuno-loop-mediated isothermal amplification assays (iLAMP) were developed by using a phage-borne peptide that was isolated from a cyclic eight-peptide phage library. One assay was used to screen eight organophosphorus (OP) pesticides with limits of detection (LOD) between 2 and 128 ng mL(-1). The iLAMP consisted of the competitive immuno-reaction coupled to the LAMP reaction for detection...

This study was conducted to investigate the preliminary environmental and mammalian toxicology of neem oil, temephos and chlorpyriphos-methyl/fenitrothion. Culex pipiens, Daphnia magna and Gambusia affinis were used to study environmental impact. A high level of toxicity was observed, with slight differences between organisms. The emulsifiers individually also displayed toxicity towards the tes...
