Abstract:

[Objectives]  To understand the effect of body weight, age, mating experience and other morphological characteristics of Spodoptera litura Fabricius on mate choice and mating success. [Methods]  Adults were weighed and marked so that individual mating success could be observed and recorded. [Results]  The majority (71.43%) of heavier males preferred to mate with smaller females, and vice versa (72.00%). Females mated with both heavier and lighter males, but heavier males had a greater chance (70.00%) of mating. Male S. litura only mated with one-day-old females but females preferred to mate with three, or five-day old, males. Mating experience influences sexual selection in S. litura; most (86.67%) virgin males mated with virgin females, whereas most (66.67%) virgin females mated with non-virgin males. The morphological characteristics of males had a more obvious effect on female mate choice. However, females’ morphological characteristics, including wing size, body length, abdomen length, eye spacing and antennae length, played a minor role in influencing male choice. [Conclusion]  Weight, age, mating experience, and morphological characteristics, of S. litura all influence mate choice in this species to different degrees.
