| Abstract: | "The sex pheromone system of Scrobipalpa salinella (Zeller), an important pest of the halophyte Salicornia europaea in the tidal salt marshes, was studied. Z3-12:OAc and Z5-12:OAc were identified from both female pheromone glands and female emissions, but in quite different ratios. Field trapping tests demonstrated that Z3-12:OAc and Z5-12:OAc are essential for optimal attraction of male moths, and a 100:5 blend found in gland extracts is significantly more attractive to males than a 100:50 ratio similar to that found in SPME samples. Small amounts of E3-12:OAc and Z5-14:OAc also were present in pheromone gland extracts. A blend of E3-12:OAc with Z3-12:OAc attracted a few males, but was not as attractive as the binary blend of Z3-12:OAc and Z5-12:OAc. Moreover, addition of E3-12:OAc did not affect captures of males to the primary binary blend. Another glandular component, Z5-14:OAc, had no behavioral activity in field bioassays. Therefore, a synthetic mixture of Z3-12:OAc and Z5-12:OAc in a 100:5 ratio can be used as an effective tool for monitoring and control of this species" |
