The parasitoid Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) is often released to manage lepidopteran pests in cotton crops. However, growers rely on multiple insecticide applications pests. A harmonious integration of control tactics required for proper pest management, and the use selective insecticides (i.e., those promoting effective while causing little impact natural enemi...

Molecular mechanisms of radiation dose-rate effects are not well understood. Among many possibilities, long-lasting sustained alterations in protein levels would provide critical information. To evaluate sustained effects after acute and chronic radiation exposure, we analyzed alterations in protein expression in the livers of mice. Acute exposure consisted of a lethal dose of 8 Gy and a sublet...

Gram-negative septicemia elicits multiple abnormalities of the coagulation system. Although products of coagulation can lead to clot formation, thereby potentiating organ damage, recent work has shown that low concentrations of thrombin can protect animals from the shock state. Because these amounts of thrombin also lead to formation in vivo of the anticoagulant enzyme, activated protein C, we ...

Immune-defective and immunologically normal F1 mice derived from the CBA/N strain were used to study the influence of anti-endotoxin antibody on the lethal effects of endotoxin. Immune-defective F1 male mice were unable to make specific responses to purified preparations of E. coli O111:B4 endotoxin, whereas their immunologically normal F1 female littermates made excellent responses. The abilit...

Deltamethrin is a pyrethroid ester insecticide widely used in agricultural and non agricultural purposes in India, creates a serious threat to the environment as well as target and non target organisms. The present investigation was undertaken to study the effect of lethal (8mg/L) and sublethal (0.8mg/L) deltamethrin level on selected haematological indices of Cirrhinus mrigala. The target fish...

objective: the toxic effects of sublethal concentrations of endosulfan on oreochromis niloticus was examined using bioaccumulation and histopathology studies of the liver as toxicological endpoint.  methods: the organization for economic cooperation and development #407 recommended static renewal bioassay was employed during the test .the test fish were exposed to sub-lethal concentrations sepa...
