Seasonal patterns of oviposition in a synanthropic unautogenous population of Culex pipiens pipiens mosquitoes from 69 suburban settlements (60 degrees 30' N, 30 degrees E') of the Leningrad province were studied during the period 1998-2002 years. The numbers of egg rafts laid in six artificial pools (barrels) were counted every day; altogether 692 rafts were collected. The general patterns of oviposition activity were similar for all studied years, in spite of their differences in the summer temperature regimes. The first peak of oviposition was observed during the second decade of July, the second peak--during the third decade of July--the first decade of August. The first and second summer generations of mosquitoes were responsible for these oviposition peaks, whereas the third generation completely entered the reproductive diapause. Thus, the oviposition activity was successfully used for populational monitoring of C. p. pipiens, that was for the first time recommended by Madder and co-authors (1980), taking into consideration the simplicity and economy of this technique. The differences in the attractiveness of distinct reservoirs for oviposition were recorded. The females preferred the barrels located on open sun-lit space and waters with organic pollution settled by mosquito larvae. Windly and rainy weather and also low (below 10 degrees C) night temperatures suppressed mosquito oviposition.
1998年至2002年期间，对列宁格勒省69个郊区定居点（北纬60度30分，东经30度）的致倦库蚊这一同城非自生种群的产卵季节性模式进行了研究。每天统计六个人工水池（桶）中产下的卵筏数量；共收集到692个卵筏。尽管各研究年份夏季温度状况有所不同，但所有年份的产卵活动总体模式相似。产卵的第一个高峰出现在7月的第二个十年，第二个高峰出现在7月的第三个十年至8月的第一个十年。这些产卵高峰是由第一代和第二代夏季蚊子造成的，而第三代蚊子则完全进入生殖滞育状态。因此，产卵活动被成功用于致倦库蚊的种群监测，这是马德等人（1980年）首次推荐的，考虑到该技术的简单性和经济性。记录了不同蓄水处对产卵吸引力的差异。雌蚊更喜欢位于阳光充足开阔空间的桶以及有蚊虫幼虫栖息的受有机污染的水域。大风和雨天以及夜间低温（低于10摄氏度）会抑制蚊子产卵。
