The water extract of Artemisia monosperma, Eichhornia crassipes and Zygophyllum coccineum was tested against the 2nd instar larvae of Culex pipiens and the resulting pupae and adults. The larvae were exposed to serial concentrations (0.5, 1.0 and 2.0%). All extracts showed marked effects on larval mortality, pupation and adult emergence as compared to the(More)
The histochemical effects of the lethal concentration that kills 50% of larvae (LC50) of three biological agents, abamectin, Bacillus thuringiensis and spinosad on the carbohydrates (polysaccharides), proteins, nucleic acids and lipids content of the midgut and fat bodies of Culex pipiens 2nd instar larvae were studied. The results showed that the three(More)
Objective: Insect immune system has a potent arsenal of antimicrobial peptides (AMPs) that cooperate to clear microbial invasions. Here we aimed to explore the immune response of Musca domestica larvae when bacterially challenged and pick up induced antibacterial genes. These genes can be used in the production of novel antibiotics to compensate for the(More)
Drought-tolerant and drought-susceptible genotypes of sorghum (Sorghum bicolor L. Monech) were analyzed by the energy-dispersive X-ray fluorescence (EDXRF) technique to study the correlation of trace elements with drought-tolerance capacities. Samples prepared from mature seeds, young seedlings, and old plants were analyzed using a 109Cd radioisotope source(More)
