Abstract
The effects of ratio between sex pheromone components, pheromone dose in the dispenser, aging of dispenser in the field, and trap type on trapping efficiency of males of the peach twig borer,Anarsia lineatella Zeller (Lepidoptera: Gelechiidae), were investigated. To attract males, the optimal ratio between pheromonal components in a binary blend containing (E)-5-decenyl acetate (E5-10:Ac): (E)-5-decenol (E5-10:OH) was 72:28 or 83:17. Dosages of 7 or 0.7 mg of the binary blend containing E5-10:Ac: E5-10:OH (72:28) were equally effective in attracting males. The effect of aging of dispenser (Israeli dispensers, loaded with 7 mg pheromone) in the field on trapping efficiency was moderate. Captures in traps baited with 4-week-old septa did not differ from those in traps baited with 1-week-old septa. The fairly slow loss of attractancy exhibited by rubber septa indicates that septa may be used for at least 4–5 weeks. At high population levels, the nonsticky IPS trap was significantly more effective in capturing males than the sticky Pherocon 1C trap; at low populations, however, the Pherocon 1C trap was better.
