| Abstract: | ABSTRACT. Both male and female Taeniopoda eques (Burmeister) emit a defensive secretion from their thoracic spiracles. The secretion from mature females was found to act as a sex pheromone, eliciting mating behaviour in males. Females became chemically attractive to males about 16–18 days after eclosion. The antennae are shown to be the site of pheromone reception in males. Feeding upon natural host plants was not a prerequisite for pheromone production. |
