| Title: | Evaluation of synthetic sex pheromone for monitoring and management of raspberry crown borer Pennisetia marginata (Lepidoptera: Sesiidae) |
| Abstract: | 1 (E,Z)-3,13-Octadecadienal (E3,Z13-18:Ald) was recently identified as a sex pheromone component of the raspberry crown borer Pennisetia marginata (Harris) (Lepidoptera: Sesiidae). Although unstable, this pheromone may have utility for monitoring the seasonal abundance and flight phenology of adult P. marginata, as well as for developing control tactics, such as disorienting mate-seeking males. Experiments conducted in raspberry and blackberry crops tested the effect of lure and trap attributes on captures of male P. marginata. 2 Increasing lure loads (10, 100 or 1000 mu g) of E3,Z13-18:Ald significantly increased trap captures. 3 Freshly prepared lures were significantly more attractive than lures aged for 2-10 days at room temperature. 4 White wing traps and white delta traps were more effective than green delta or green bucket traps. 5 Trap height in the crop canopy had no effect on the capture of males. 6 When sex pheromone components of three other sesiid moth species were added to E3,Z13-18:Ald, the attraction of male P. marginata was reduced and, thus, these components were identified as pheromone antagonists. 7 Pheromone-based mass trapping with 25 wing traps per hectare reduced captures of males in traps baited with a low-dose (10 mu g) pheromone lure by 67-87% in 2011. |
