Description
Abstract: ABSTRACT: The lifetime mating pattern of Culex tarsalis males was determined under insectary conditions. Thirty males were individually confined in 4 liter carton cages and were offered new harems of 4-8 day-old virgin females each day from emergence to death. The numbers of males alive and females inseminated per day were used to calculate male life tables, applying statistical method developed for female mosquitoes. Male survivorship was estimated to be 98% per day and life expectancy was 29 days at emergence. The mortality rate was greatest between days 15 and 21 of adult life, when 33% of the cohort died. The number of males mating per day was greatest between days 2 and 9, decreasing to zero by day 37. Mating activity was renewed between days 46 and 55. The maximum number of females mated per male per night was 4. Mean lifetime reproductive effort was 12.2 females inseminated per male (range = 0 to 29). Four males accounted for 105 (29%) of the total 360 inseminations. Reproductive effort (females inseminated per male) increased as a function of male longevity, i.e., males living longer inseminated more females.
