Technical Abstract: We evaluated the importance of multiple mating to female reproductive output in the psyllid Diaphorina citri. When held for 24 h with one or three males, females showed a marked decline in fecundity beginning about 10 d and 15 d after mating, respectively. Fecundity remained relatively high for females that were paired with one male for 2 weeks, but oviposition was low and mortality high when females were held with three males for 2 weeks. In treatments in which females were held with males for 2 weeks, oviposition increased dramatically in the days following removal of males. For females paired with a male for 24 h and repaired for 24 h after 9 d, fecundity remained high throughout our 18-19 d observation period. Egg fertility did not differ among mating treatment, but varied over time in a manner that was similar among treatments.
