Abstract: | [ Objective ] The aim was to find a safe and environmental technology to control rice stem borer. [ Method] Control effect of phero- mone against rice stem borer was studied. [ Result] The 25 trapping points of pheromone totally trapped 1 727 rice stem borer within 100 days, among them the overwintering generation moth and first generation moth of rice stem borer were 1 128 and 599, respectively; mating rates of the overwintering generation moth and first generation moth were 21.66% and 50.92%, respectively. Control effieiencies of the first and second generation moth of rice stem borer were 41.60% and 86.70% in tested area, and were 82.00% and 81.60% in control area, re- spectively. The tested area had three times of applying pesticide less than control area, so one season rice could save 201 yuan/hm2. [ Con- clusion] Pheromone has strong trapping effect, so it can be applied in controlling rice stem borer. |
