Abstract
Tests were conducted in 1986 on A. lineatella, and in 1987 and 1988 on both A. lineatella and G. molesta, to compare commercially available pheromone traps and dispensers.
Results of A. lineatella trap comparisons indicated that wing-style traps captured significantly (P < 0.05) more moths than other trap styles tested, and that the nonsaturating Multipher and IPS traps and the Pherocon II trap captured the least.
A Multipher trap with DDVP as killing agent captured more G. molesta in 1987 than other traps tested including a Multipher trap with water.
The Multipher trap also captured the most moths in 1988 although a similar number of moths were captured in the Pherocon wing trap.
Characteristics of A. lineatella and G. molesta moth captures were different between dispenser types and within dispenser type over the season and between years.
In general, the membrane type of dispenser captured the most moths of both species over the season, and also attracted moths at a level ≥ that of a new Trece rubber septa for a longer period of time.
Moth captures using different dispensers tended to be more similar to one another over the first 4 weeks of exposure than when compared over the season.
During this period, Trece rubber septa tended to have lower standard errors relative to mean moth capture (generally within 30% of mean moth capture) than the other dispenser types.
