Resurgence of Japanese mealybug, Planococcus kraunhiae (Kuwana), in persimmon induced by a synthetic pyrethroid cypermethrin

Biomarkers of Cypermethrin (Synthetic Pyrethroid) Toxicity - Biochemical alterations in Cyprinus carpio, a freshwater edible fish

Biochemical markers are measurable responses to the exposure of an organism to xenobiotics as well as very suitable biosensors of aquatic pollutants. Aquatic pollution can easily be detected through biomarkers, as enzymes provide one of the most reliable means of assessing the degree of exposure of animals to pollutants. Some of the biochemical alteration occurring in the body gives the first i...

SHORT COMMUNICATION IMMUNOTOXIC RESPONSES OF CYPERMETHRIN, A SYNTHETIC PYRETHROID INSECfICIDE IN RATS

The study was undertaken to evaluate immunotoxic effecls of eypermethrin administered orally (in ground nut oil) to male albino rats at dose levels (mglkg) of 0 (control). 5. 10. 20 and 40 once daily for 90 days. Cypermethrin administration produced a significant leucopenia at 40 mglkg on day 90. A dose dependent decrease (P > 0.05) in delayed type hypersensitvity reaction was noticed on day 61...

Comparative efficacy of Solanum xanthocarpum extracts alone and in combination with a synthetic pyrethroid, cypermethrin, against malaria vector, Anopheles stephensi.

With a goal of minimal application of environmentally hazardous chemical insecticides, the larvicidal activity of cypermethrin was studied alone and in combination with the root extract of Solanum xanthocarpum against anopheline larvae. Petroleum ether extract was observed to be the most toxic, with LC,, of 1.41 and 0.93 ppm and LC90 of 16.94 and 8.48 ppm at 24 and 48 hours after application, r...

Molecular Evidence of Polyandry in the Citrus Mealybug, Planococcus citri (Hemiptera: Pseudococcidae)

The occurrence of polyandry in Planococcuscitri, presumed by earlier observations of mating behavior, was confirmed using microsatellite genotyping of pools of over 400 eggs resulting from controlled crosses of one female with two males. The genetic contribution of both mated males was confirmed in 13 out of 43 crosses. In three crosses it was possible to determine that only the first male fert...
