Abstract: Mass-trapping with kairomone lures is one of the control approaches in management of fruit-boring moth pests in orchards. The challenge lies in developing kairomone lures that can trap both males and females. We conducted field trials in pear orchards to examine the trapping efficacy of kairomone lure preparations that varied in proportion and combination of codling moth sex pheromone and plant volatile chemicals, including pear ester, acetophenone, geraniol, Methyl salicylate, and 2-phenylethanol. A commercial codling moth sex pheromone was used as the control. The tapping trials were tested during the early and middle occurrence of major fruit-boring moths in pear orchards at Kurle and Aksu in southern Xinjiang. The trap catches of Cydia pomonella at both sites showed that the lure preparations containing both sex pheromone and plant chemicals caught more females compared to those containing only sex pheromones; yet the number of females trapped was still small. The trap catches of Grapholitha molesta at Kurle showed that most of the lure preparations caught more moths than the control; the lures containing both sex pheromone and a small amount of plant chemicals that were devoid of pear ester trapped somewhat more than those with only sex pheromones. At Aksu, all lure preparations trapped more C. pomonella moths than the commercial product; there was not a difference between those with and without plant chemicals. The trapping catches of Euzophera pyriella showed that the lure preparations containing only sex pheromone or its mixture with pear ester trapped more moths than the other preparations. Our mass-trapping results suggest that tested lure preparations containing both C. pomonella sex pheromone and plant volatile chemicals are not effective in attracting C. pomonella females, but some are effective to male noctuid moths co-occurring in the orchards.
