Season-long trapping trails during summers of 2004 and 2005 in China demonstrates that there were noticeable seasonal shifts for trapping Chilo suppressalis males. At higher night-temperature (approximately 28℃), a lure containing 2:1 mixture of Z11- and Z9-hexedecanal combined with 10.1% of Z13-18-octadecenal, produced five-fold trap catches as did the natural blend, compared to the ratios at a lower night-temperature (<25℃) ranging from 1.52 to 1.87. Further studies indicated that the trap catch depended on the ratio of Z11- and Z9-hexedecanal, other than each acted independently. Besides female population density reported, two correlative factors, the night-temperature and the ratio of Z11- and Z9-hexedecanal contained in the pheromone blend, may possibly affect trap catch of male moths.
