通过使用梨小食心虫性诱剂诱捕梨小食心虫成虫,总结了梨小食心虫在赣中地区梨园从生长发育期到采摘期的发生规律。比较了性诱剂与糖醋酒液、频振式杀虫灯的诱杀效果,进行了梨小食心虫的预测发生期化学农药防治和幼果套袋防治试验。试验结果表明,第1代成虫发生高峰期明显,采用预测发生期化学防治效果较好;第2代和第3代成虫之间的界限不明显,相互重叠,宜采用幼果套袋进行防治。 Through the use of pest insects pest lure induced trapping insects Pear’s worm, summed up the pears in the Central Jiangxi pear district from the growth and development period to picking the law of occurrence. The trapping and killing effects of sexual attractants, sweet and sour wine liquor and frequency vibration type insect light were compared, and the chemical pesticides control and young fruit bagging prevention and control test were carried out. The results showed that the first generation of adults had a peak at the peak, and the predicted chemical control effect was better. The boundaries between the second generation and the third generation of adults were not obvious and overlapped each other.
