用性信息素诱捕法防治梨小食心虫Grapholitha molesta(Busck)的试验于1978—1980年在辽宁省绥中县的梨园中进行。1978、1979和1980三年的诱捕防治面积分别为2、100和780公顷。在田间试验中每公顷使用10—15个梨小食心虫性信息素水碗诱捕器。在对照区,每年8月至9月喷2次杀虫剂防治梨小食心虫,在诱捕区不喷这两次药。 试验是成功的。1978、1979和1980年,诱捕区梨小食心虫的虫果率分别为1.4—4.4％、0.4—2.0％和0—1.2％,而化学防治对照区分别为7.6—8.6％、3.3％和0.3—2.7％。诱捕区梨小卵的寄生率为32.6—75.9％;在化学防治对照区只有10—26.6％。诱捕区的防治费用比化学防治区节省78—89％。
The test of controlling pest of Grapholitha molesta (Busck) with sex pheromone trapping was carried out in the pear orchard in Suizhong County, Liaoning Province from 1978 to 1980. Trafficking control areas in 1978, 1979 and 1980 were 2,100 and 780 hectares, respectively. In the field trials 10-15 pear pestelioid pheromone water puddle traps were used per hectare. In the control area, pest control pest insects were sprayed 2 times a year from August to September, and the two drugs were not sprayed in the trapping area. The test is successful. In 1978, 1979 and 1980, the worm fruit rates in the trapping area were 1.4-4.4%, 0.4-2.0% and 0-1.2%, respectively, while the chemical control areas were 7.6-8.6%, 3.3% and 0.3- 2.7%. The parasitization rate of pear pests in the trapping area was 32.6-75.9%; only 10-26.6% in the chemical control area. Trap prevention and treatment costs than chemical prevention and control area to save 78-89%.
