Histochemical Effects of Some Biological Agents on Culex Pipiens Larvae.
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 tested compounds reduced the carbohydrate...
متن کاملBioefficacy of Some Egyptian Aromatic Plants on Culex pipiens (Diptera: Culicidae) Adults and Larvae
BACKGROUND Protecting the environment from chemical hazards of synthetic insecticides along with offering of new breeding areas for vectors by urbanization indicate the trial of natural insecticides. METHODS The acetone extracts of Anethum graveolens, Ocimum basilicum and Thymus vulgaris were tested for their insecticidal effect on Culex pipiens adults and larvae in different concentrations d...

متن کاملInsemination rates of hybrids between Culex pipiens pipiens and Culex pipiens quinquefasciatus or Culex pipiens pallens at high temperature.
Females of Culex pipiens pallens are rarely inseminated at temperatures above 30 degrees C. Insemination and egg-hatching rates (F2) were examined in females of hybrids (F1) between Culex pipiens pipiens and Culex pipiens quinquefasciatus at 25 degrees C and 30 degrees C to examine temperature-dependent reproductive activity. Insemination rates were very high in hybrid females (F1) at 25 degree...
متن کاملToxicological Effects of Some Heavy Metal Ions on Culex pipiens L. (Diptera: Culicidae)
Different concentrations of selected heavy metals in the form of cadmium chloride (CdCl2), copper sulphate (CuSO4), lead nitrate (Pb (NO3)2) and mercuric nitrate (Hg (NO3)2) were tested against immature and mature stage of C. pipiens to assess the toxicity, LC50, total carbohydrate and lipid content. The survival potential of 2 instar larvae was highly affected by the contamination with the tes...
