Abstract:Field and laboratory populations of the parasitoid Asecodes hispinarum Bouek were randomly sampled,and sex ratios,the number of emerged and unemerged adults and egg numbers compared between the two populations.t-test indicated that these parameters differed significantly between the two populations.The proportion of females in the field population was 81.63%±2.54% compared to 65.34%±1.80% in the laboratory population and the number of emerged adults in the field population was 25.13±1.17 compared to 52.90±1.88 in the laboratory.The effect of host size on sex ratio was analyzed by correlation analysis;no relationship between host size and sex ratio was observed.This result is contrary to the prediction derived from Charnov’s model.
Keywords:Asecodes hispinarum  population differences  sex ratios
