Summary:In a four-armed airflow olfactometerTrichogramma evanescens Westwood females were attracted by a volatile substance(s) released by virgin females of the great cabbage white butterfly,Pieris brassicae L. Males or recently mated females did not cause attraction. Furthermore,T. evanescens was also attracted by volatiles released by calling virgin cabbage moths,Mamestra brassicae L. However, the parasites did not respond to (Z)-11-hex-adecenylacetate (the main component of the sex pheromone ofM. brassicae), a crude hexane extract of the sex pheromone gland, or to males or recently mated females.
