摘要: 为明确梨小食心虫性信息素迷向散发器对单植梨园和毗邻苹果园的梨园内梨小食心虫的防治效果和合理使用密度,本研究于2012、2013和2014年在山西省运城市采用每根含270 mg梨小食心虫性信息素的散发器进行了梨小食心虫迷向防治试验。结果表明,单植梨园和毗邻苹果园的梨园以600、900和1200根/hm2处理,对梨小食心虫的迷向率逐年提高,且高密度处理迷向效果更好;连续使用3年后,梨小食心虫的蛀果率显著低于对照园,单植梨园内防治效果分别为80.00%、90.00%和90.00%,毗邻苹果园的梨园则分别为69.23%、84.62%和84.62%,单植梨园效果好于毗邻苹果园的梨园。综合防治成本和效果,建议单植梨园可使用900根/hm2密度处理,毗邻苹果园的梨园使用1200根/hm2以上密度处理,并建议大面积连片使用3年以上。

Abstract: The effects and reasonable density of a dispenser containing 270 mg of sex pheromone for mating disruption control of Grapholitha molesta (Busck) in mono- and mix-cultured pear orchards were tested using the densities of 600, 900 and 1200 dispensers per hectare in Yuncheng, Shanxi Province from 2012 to 2014. The rates of mating disruption increased with increasing seasons and density. With three years' application, the rates of infested fruits in both the mono- and mix-cultured pear orchards were significantly lower than that in the untreated orchards. The control efficacies of the sex pheromone dispenser in the mono-cultured orchards were 80.0%, 90.0%, and 92.9% for the three years, respectively. In contrast, they were 69.2%, 84.6%, and 84.6% in the mix-cultured orchards, respectively. Considering control efficacy and cost, we recommend to apply the dispenser at 900 and 1200 per hectare for more than three successive years in large-scale mono- and mix-cultured pear orchards, respectively.

Key words: Grapholitha molesta, sex pheromone, mating disruption, single pear orchard, mixed pear orchard
