|Title:||Temporal Variation in the Sex Ratio of a Natural Population of a Multivoltine Gall-Inducing Braconid Wasp|
|Abstract:||Temporal variation in the sex ratio of populations with continuous generations is poorly understood. We report changes in the sex ratio of a tropical gall-inducing braconid wasp throughout the fruiting season of its host plant. At the beginning of the season, fruits produce male biased sex ratios; at the end, female biased sex ratios. This change results from differential sex allocation rather than just earlier male emergence. A male bias followed by female bias is predicted following an increase in recruitment as occurs during the start of the main fruiting season, because males are likely to have the more consistent reproductive value over time. An initial male bias might also result from selection for protandry, or from constrained sex allocation during the low-density non-fruiting season.|
