Abstract

Summary

A comparison was made between the reproductive potential of the selected dieldrin-resistant El Salvador and the dieldrin-susceptible Panama populations of . The fecundity rate in both was about the same, but the fertility rate was slightly higher for the El Salvador females.

Sexual activity of the two populations was determined by single and multiple choice mating experiments. In general, both males and females of the resistant population from El Salvador appeared to be more aggressive than were the adults of the Panama colony.

This study suggests that the development of dieldrin resistance in the El Salvador population was not accompanied by a loss in competitive advantage through reduced reproductive potential.
