Estimation of survival and gonotrophic cycle length of Culicoides variipennis (Diptera: Ceratopogonidae) in California.
The use of a time series analysis to estimate the survival rate and gonotrophic cycle length of Culicoides variipennis at 2 California sites is described. Collections were made daily for 28 days in Yolo County (northern California) and for 25 days in Riverside County (southern California) in July and August of 1989, respectively, using CO2-baited suction traps. The time series analysis of these collections yielded a gonotrophic cycle length estimate of 3 days. Stage-specific and daily survivorship estimates 0.242 and 0.623, respectively, were determined for the northern California site. The time series method was found unsuitable for estimating the gonotrophic cycle length or daily survivorship at the southern California site.
