Abstract

<abstract abstract-type="main"> <title>Abstract</title> <p> <list list-type="order"> <list-item> <p>(<italic>E</italic>, <italic>Z</italic>)‐3, 13‐Octadecadienal (<italic>E</italic>3, <italic>Z</italic>13‐18:Ald) was recently identified as a sex pheromone component of the raspberry crown borer <italic>Pennisetia marginata</italic> (Harris) (Lepidoptera: Sesiidae). Although unstable, this pheromone may have utility for monitoring the seasonal abundance and flight phenology of adult <italic>P. marginata</italic>, 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 <italic>P. marginata</italic>.</p> </list-item> <list-item> <p>Increasing lure loads (10, 100 or 1000 µg) of <italic>E</italic>3, <italic>Z</italic>13‐18:Ald significantly increased trap captures.</p> </list-item> <list-item> <p>Freshly prepared lures were significantly more attractive than lures aged for 2–10 days at room temperature.</p> </list-item> <list-item> <p>White wing traps and white delta traps were more effective than green delta or green bucket traps.</p> </list-item> <list-item> <p>Trap height in the crop canopy had no effect on the capture of males.</p> </list-item> <list-item> <p>When sex pheromone components of three other sesiid moth species were added to <italic>E</italic>3, <italic>Z</italic>13‐18:Ald, the attraction of male <italic>P. marginata</italic> was reduced and, thus, these components were identified as pheromone antagonists.</p> </list-item> <list-item> <p>Pheromone‐based mass trapping with 25 wing traps per hectare reduced captures of males in traps baited with a low‐dose (10 µg) pheromone lure by 67–87% in 2011.</p> </list-item> </list> </p> </abstract>
