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...

Development of the immature stages of Culex (Culex) saltanensis Dyar (Diptera, Culicidae) under laboratory conditions. Culex (Culex) saltanensis Dyar, 1928 is becoming frequent and abundant in natural and artificial breeding sites in urban and rural areas of Brazil. This study contributes to the knowledge of the biology of a Brazilian strain of C. saltanensis. The development of specimens reare...
متن کاملSCIENTIFIC NOTE Effect of Oviposition Site Deprivation on Oviposition Perfor- mance and Egg Hatch Rate of Naturally Blood–fed Gravid Culex quinquefasciatus (Diptera: Culicidae)
The effect of oviposition site deprivation on oviposition performance and egg hatch rate of naturally blood–fed gravid Culex quinquefasciatus was examined in the laboratory. The rate of gravid females ovipositing within 24 hours was not significantly affected by the period of oviposition site deprivation that ranged from 1 day to 9 weeks. However, some gravid females failed to form egg rafts, a...
متن کاملOviposition preferences of Culex pipiens and Culex restuans for infusion-baited traps.
The number of egg rafts oviposited by Culex pipiens and Culex restuans in infusion-baited ovitraps varied with the type of infusion substrate, infusion age, method of infusion preparation, and calendar date. In one or more tests, more Culex egg rafts were collected from water infused with Kentucky bluegrass sod, mixed grass clippings, straw, or a commercial rabbit chow than from a water control...
متن کاملCulex restuans (Diptera: Culicidae) oviposition behavior determined by larval habitat quality and quantity in southeastern Michigan.
Oviposition is a critical stage in the mosquito lifecycle, and may determine population levels, distribution, biting behavior, and pathogen transmission. Knowledge of the oviposition behavior of Culex restuans Theobald has become particularly important with the emergence of West Nile virus (WNV) in North America. Laboratory and field studies have examined some factors that contribute to oviposi...
