摘要
从生态健康理念出发,以巴州沙依东生态健康果园为研究对象,利用性诱剂对不同设置密度的性信息素样地内的梨小食心虫进行信息素迷向防治,并做了梨小食心虫的消长动态监测研究。研究表明,梨小食心虫在巴州地区1年发生4代。在0.067 hm2香梨园内放置32根信息素迷向管对梨小食心虫的迷向率为86.75%,其蛀果率也较低,相对防效为87.16%。
From the ecological concept of health, taking the ecological healthy orchard in the Shayidong of Bazhou prefecture as the research object, sex traps were used to prevent Grapholitha molesta which are in plots of different density of sex pheromone; the growth and decline trends of Grapholitha molesta were studied. Results are as follows： 4 generations of Grapholitha molesta happened in Bazhou prefecture every year. The isotropie rate of controlling Grapholitha molesta are 86.75% in the 0. 067 hm2 of pear orchard with placing 32 isotropic tubes, the moth rate is very low and relatively efficiency are 87. 16% in the same district.
