Toxic Response of Mosquito Culex Quinquefasciatus (Diptera: Culicidae) to some Agricultural Pesticides (Butachlor and Pertilachlor)
Background: The expansion of herbicide used in aquatic ecosystems as well as in terrestrial if is not properly controlled may produce harmful effects on freshwater fisheries. Residue limits of these agricultural chemicals in tropical fishery waters should be established. The aim of this study was to determine the acute toxicity of butachlor and pertilachlor as potential dangerous herbicides to ...
متن کاملToxicity of Beauveria bassiana-28 Mycelial Extracts on Larvae of Culex quinquefasciatus Mosquito (Diptera: Culicidae)
Microbial-based pest control is an attractive alternative to chemical insecticides. The present study sought to evaluate the toxicity of the entomopathogenic fungus Beauveria bassiana-28 ethyl acetate extracts on different larval stages and pupae of Culex quinquefasciatus mosquitoes. B. bassiana-28 ethyl acetate mycelial extracts produced mosquitocidal activity against larvae and pupae which wa...
متن کاملStable, germ-line transformation of Culex quinquefasciatus (Diptera: Culicidae).
A Hermes-based transposable element transformation system incorporating an enhanced green fluorescent protein (EGFP) marker was used to produce two transgenic lines of Culex quinquefasciatus (Say). The transformation frequency was approximately 12% and transformation of Culex was shown to be dependent on the presence of Hermes transposase. Injected Culex embryos were treated with four different...
متن کاملRT-PCR assay for the detection of infective (L3) larvae of lymphatic filarial parasite, Wuchereria bancrofti, in vector mosquito Culex quinquefasciatus.
BACKGROUND & OBJECTIVES Periodic monitoring of vector population for infection and infectivity rates is central to the evaluation of the filariasis elimination strategies in endemic areas to monitor the success of MDA and also to establish endpoints for intervention. The main objective of this study was to develop a RT-PCR assay, based on L3 stage-specific primers to detect the presence of infe...
متن کاملOvicidal activity of neem products (azadirachtin) against Culex tarsalis and Culex quinquefasciatus (Diptera: Culicidae).
Bioactive compounds contained in the seed kernel and other parts of the neem tree (Azadirachta indica A. Juss) have been found to show insecticidal activities and other effects in many species of insects. These activities include antifeedancy, growth regulation, fecundity suppression, male sterility, oviposition repellency, changes in biological fitness such as loss of flying ability, immunodep...
