Examination of sex attractants for monitoring weed biological control agents in Hawaii.

摘要

The identification of sex attractants was undertaken for potential use in the study of two biological control agents against Rubus spp. (R. argutus, R. ellipticus, R. niveus and R. hawaiensis) in Hawaii, USA. Attractants for Croesia zimmermani and Schreckensteinia festaliella were developed by field screening a variety of putative lures in sticky traps, based on attractants for congeneric species. Croesia zimmermani was most attracted to E11-tetradecen-1-ol and E11-tetradecenal, while S. festaliella was attracted to (10,12)-(E,E)-hexadecadienal alone. Development of monitoring systems based on sex attractants can enable better evaluation of biological control programmes, and provide cost-effective information on presence/absence, density, phenology, synchrony with the host, dispersal rate and other useful parameters..
