The molluscicidal activity of Bauhinia variegata leaf and Mimusops elengi bark was studied against vector snail Lymnaea acuminata. The toxicity of both plants was time and concentration-dependent. Among organic extracts, ethanol extracts of both plants were more toxic. Toxicity of B. variegata leaf ethanolic extract (96h LC50- 14.4 mg/L) was more pronounced than M. elengi bark ethanolic extract...

Demographic toxicology is recommended for toxicity determination of the long term effects of a pesticide since it gives a more accurate and efficient measure of the effect of a pesticide. Thus, in the current study the sublethal effects of pirimicarb (carbamate insecticide) two concentrations of LC30 and LC10 were used against third instar larvae of Hippodamia variegata (Goeze) in order to dete...

Background: Melanoma is a metastatic type of skin cancer that is difficult to treat and the majority of efforts are directed to the design of new drugs. Medicinal Plants have been the primary source of medicines since life on earth; more than 50% of existing cancer treatments is derived from plants. Bauhinia variegata is well-known medicinal plant used from the ancient era to till date for thei...

prey preference of natural enemies is among the phenomena that should be considered in determining the efficacy of natural enemies. when the predators are faced with a choice between two or more preys, they often show their preference to one from among them. temperature is one of the environmental factors that can affect insect foraging behavior. two aphid species namely aphis fabae and acyrtho...

predation rate is basic to any investigation of prey-predator interaction and a major component in the selection of predators for biological control. the predation rate of variegated lady beetle, hippodamia variegata (goze), fed on different densities (20, 40, 60, 80 and 100) of third instar nymphs of cotton aphid, aphis gossypii glover, was studied under laboratory conditions (25 ± 1 °c, 65 ± ...
