Study on the Effect of Intelligent Sex Pheromone Mating Disruption Sprayer on Controlling Rice Stem Borer
In order to explore the effect of intelligent sex pheromone mating disruption sprayer on controlling rice stem borer Chilo suppressalis,intelligent sex pheromone sprayers were set up for disruption the mating.The number of moths was monitored using sex pheromone attract-ants and the harm of C.suppressalis to rice was investigated in the study.The total number of moths attracted by sex pheromone attractants in the sprayer controlling area was significantly lower than that in the pesticide controlling area.At the same time,sex pheromone sprayers changed the dynamics of trapping the moths.The number of moths attracted by sex pheromone in pesticide control area was significantly higher than that in the sprayer controlling area,when the number of moths in the field is large.Compared with pesticide,sex pheromone sprayer sig-nificantly reduced the damage rate of C.suppressalis and significantly increased the control effect to 92.3%±1.8%.Our results indicate that intelligent sex pheromone mating disruption sprayer is an efficient and green control technology for Rice Stem Borer,and can significantly reduce the use of chemical pesticides.
