the use of resistant cultivars remains one of the most reliable methods to manage the pests. in this study the mechanism of resistance in 10 lines of rice for 3 kinds of resistance (antixenoses, antibioses and tolerance) was studied. the egg set of striped stem borer on the leaf of considered lines for antixenoses and larva weight mean and survival percentage of larva were evaluated for antibio...

We tested the host specificity of two South American Pseudacteon phorid flies, P. obtusus Borgmeier and P. borgmeieri Schmitz, on North American colonies of the red imported fire ant, Solenopsis invicta Buren, and the tropical fire ant, S. geminata (F.). Sequential host specificity tests conducted in the laboratory indicated that P. obtusus was highly specific to S. invicta . In individual tria...

The well-known sex-determining cascade of Drosophila melanogaster serves as a paradigm for the pathway to sexual development in insects. But the primary sex-determining signal and the subsequent step, Sex-lethal (Sxl), have been shown not to be functionally conserved in non-Drosophila flies. We isolated doublesex (dsx), which is a downstream step in the cascade, from the phorid fly Megaselia sc...

The development of indigenously isolated entomopathogenic nematodes as biological control agents was investigated. The study involved three nematode species (Heterorhabditis indica, Steinernema thermophilum and S. glaseri) and their pathogenicity against larvae of cabbage butterfly, Pieris brassicae, under laboratory conditions. Nematodes of different concentrations (0, 10, 25, 50, 75, and 100 ...
