Abstract

Pheromones released by adults of the bean bug, Riptortus linearis (Fabricius), were investigated using adultbaited traps on Okinawa Island. Males confined in an insect cage attracted adults of both sexes and 2nd stadium nymphs in a field test, which indicates that the male bug releases an aggregation pheromone. On the other hand, only males were caught in a trap baited with females. This fact suggests that the female bug releases a sex pheromone.
