【Abstract】 Field tests of the effects of the mass trapping with synthetic sex pheromone on tice stem borer, Chilo suppresalis (Walker), were conducted in Guangde County of Anhui Province in 1997-1998. The results showed that 60%-68% of decrease rate in the number of egg masses was caused by laying out green rubber pheromone dispersers 30,45,90 dish/hm 2. The number of eggs was reduced by 74% and the percent of dead tillers was decreased, too.更多还原
