Relatively few studies have investigated potential interactions of host plant resistance and insecticides for insect control. To examine possible interactions, host plant resistance was measured independently for four tomato cultivars and one wild tomato accession against tomato psyllids, Bactericerca [Paratrioza] cockerelli [Sulc] (Homoptera: Psyllidae). Plant lines tested included the commerc...

Calypso (thiacloprid), Poncho (clothianidin), Gaucho (imidacloprid), and Jade (imidacloprid) are commercial neonicotinoid insecticides, a new class of agrochemicals in México. However, genotoxic and cytotoxic studies have not been performed. In the present study, human peripheral blood lymphocytes (PBL) were exposed in vitro to different concentrations of the four insecticides. The genotoxic an...

Environ.Entornol.12:1026-1030(1983) ABSTRACT During ]979 and 1981, populations of ground-dwelling predators and parasites in research and commercial cabbage fields in upstate NewYork were assessed by pitfall trapping tn determine species composition, abundance, phenology, and the impact of insecticides on them. Staphylinidae, Phalangida, Carabidae, and Araneida were consistently the most abunda...

Insect pathology has a long history dating back to the earliest studies in microbiology. A select few of the many known insect pathogens can be produced and used on an industrial scale as biopesticides and are championed for their low environmental impact. The commercial application of microbial insecticides has been limited competition with chemical insecticides. However, the advent of gene te...

IN T RODUC T ION Pyrethroids are synthetic compounds similar to natural pyrethrins. They are commonly used in both commercial agriculture and households as insecticides and insect repellents. Unlike other common classes of insecticides, such as organophosphates and carbamates that are acetylcholine esterase inhibitors or nicotinic acetycholine agonists, the pyrethroids act upon neuronal sodium ...

Synthetic pyrethroids are synthesized derivatives of naturally occurring pyrethrins, which are taken from pyrethrum, the resin extract of dried chrysanthemum flowers. They were introduced to provide a less hazardous and less persistent alternative to organochlorine and organophosphate insecticides. They are among the safest insecticides available on the basis of their low acute toxicity to mamm...

An analytical method for the routine simultaneous determination of four nicotinoid insecticides (acetamiprid, imidacloprid, thiacloprid and thiamethoxam) in commercial multifloral honey was developed. Fortified honey samples, dissolved in water, were cleaned up through Extrelut NT20 column and, finally, insecticides were eluted with dichloromethane. The eluate was evaporated, the residue rediss...

background : lindane is an insecticide which is used in commercial insecticides and food containers. caseâ presentation : herein, we reported on a 62-year-old man with liver cirrhosis 12 years after continuous exposure to lindane gas.the diagnostic workup showed no other possible cause, and findings of liver scintigraphy and clinical manifestations were compatible with substance-induced cirrhos...
