| Popis: | To develop new and improved pest management strategies against Trigonotylus caelestialium (Kirkaldy) (Heteroptera: Miridae), a major pest of rice in Japan, it is important to understand the mating behavior of this species. In this study, we examined the effect of mating on subsequent mating receptivity and longevity in female T. caelestialium. After mating, females temporarily exhibited decreased mating receptivity. In addition, the cumulative remating frequency of females that mated with a male that had just mated with another female was higher than that of females who mated with virgin males. As a result, we hypothesized that the male ejaculate reduces female mating receptivity. Furthermore, mated females survived longer without food and water than virgin females; on the other hand, the life span of mated females with access to food and water was less than that for virgin females. |
