Influence of amphibian and reptile on the feeding preference, longevity and reproductive capacity of Egyptian culex [culex] pipens linneaus [dipera-culicidae]

Using Bufo regularis and ten reptile species as hosts for Culex pipiens under laboratory conditions revealed a great effect on feeding preference as a significant long feeding periods together with a significant reduction in the blood meal ratios were recorded. Female mosquitoes offered the experimental animals showed a short life span with different significant levels. A recognizable reduction in the reproductive fitness of Cx. pipiens females was recorded. Delayed oviposition and low ICI values was obtained. The percentage of egg hatching was not affected by the experimental animals

Laboratory studies on the possibility of culex [culex] pipiens L. to harbour and transmit hepatozoon matruhensis to the Egyptian snake psammophis schokari

A successful experimental infection of Psammophis schokari snake with Hepatozoon matruhensis through Culex [Culex] pipiens bites was carried out under laboratory condition of 20 +/- 1°C and 60-70% R.H. The period monitored for gametocyte maturation ranged from 38 to 42 days while the recorded prepatent period ranged from 28 to 35 days. The effect of infection was nonsignificant on longevity, incubation period and percenttage of egg hatching [P > 0.05]. Meanwhile a significant increase [P < 0.05] in the preoviposition period together with a significant reduction [P <0.001] in the number of eggs deposited of infected females were recorded
