Imazalil, cypermethrin and carbendazim are detected in plants for human nutrition. To explore whether their combinations, applied orally in low doses, would induce changes in metabolic patterns and hepatotoxicity, a subchronic in vivo experiment was conducted. Doses of 10mg/kg of imazalil (im) and cypermethrin (cy) and 20 mg/kg of carbendazim (car) and their combinations (im, 10 mg/kg+cy, 10mg/...

Cypermethrin is a synthetic pyrethroid pesticide widely used to protect crop against pest and insect, resulting human health and their related environment are under great risk due to undesirable toxicity. The present study was carried out to evaluate extinct of damage caused by subcutaneous introduction of cypermethrin on liver and kidney tissue of mice model. Forty switch albino mice were disp...

The repellent efficacy of 15% N,N-diethyl-3-methylbenzamide (DEET), 0.6% citronella oil, and 0.3% alpha-cyano-cypermethrin against Culicoides species was compared in three 5x5 Latin squares (15 replicates) under South African field conditions. DEET, citronella oil or alpha-cyano-cypermethrin were applied to polyester meshes that were fitted to down-draught suction 220V UV light traps which were...

Laboratory bioassays were done to determine the level of resistance to endosulfan, cypermethrin, deltamethrin, methamidophos, profenofos and chlorpyrifos in field populations of cabbage aphid, Brevicoryne brassicae (L). Comparison between Multan and Kabirwala strains revealed that the level of resistance in Multan strain was comparatively higher to methamidophos, profenofos and chlorpyrifos as ...

Cypermethrin was administered to Heteropneustes fossilis in chronic concentration to determine lesion of liver as indicators of tissue damage. The cypermethrin dose used was 1/4 of 96 hr LC50. Histopathological changes in liver ranged from vacuolization, necrosis, fibrosis of perivascular region and disposition of yellow brown grains at different time of exposure viz; 20th, 30th, 40th and 60th ...

Susceptibility of Alphitobius diaperinus (Panzer) (Coleoptera, Tenebrionidae) to cypermethrin, dichlorvos and triflumuron in southern Brazil. The lesser mealworm, Alphitobius diaperinus (Panzer), is an important insect pest in poultry houses in Brazil. Susceptibility of the lesser mealworm collected from eight poultry houses in Paraná state, southern Brazil, was evaluated for cypermethrin, dich...

Sublethal effects of cypermethrin and carbofuran on hematological parameters and their complete recovery were studied in Labeo rohita as a function of exposure time. Exposure of Labeo rohita to sublethal levels of cypermethrin and carbofuran resulted in significantly (P<0.05) lower values for erythrocyte count (RBC), hemoglobin content (Hb), and hematocrit compared with the control group. In co...

A rugged method has been developed on the Agilent 240 Ion Trap GC/MS using GC EI/MS^3 in blueberry matrix for cypermethrin. The method easily meets the requirements of fruit growers in the Pacific Northwest responsible for importing and exporting blueberry/caneberry. Cypermethrin is a synthetic pyrethroid used as an insecticide in large-scale commercial agricultural applications as well as in c...

Biological control is usually used in combination with chemical control for practical agricultural applications. Thus, the influence of insecticides on the natural predators used for biological control should be investigated for integrated pest management. The ladybird Harmonia axyridis is an effective predator on aphids and coccids. Beta-cypermethrin is a broad-spectrum insecticide used worldw...

Fall armyworm Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae) is an important pest of maize (Zea mays L.) crops in Brazil. The effects of beta-cypermethrin, chlorfenapyr, chlorpyrifos, spinosad, etofenprox, triflumuron, alpha-cypermethrin/teflubenzuron, and lambda-cyhalothrin/thiamethoxam on Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) immature stages we...
