刮树皮、绑诱虫带、清洁果园以及覆土是防治越冬代梨小食心虫的主要技术措施,但缺少系统的定量化评价,在生产上未得到广泛应用。针对这一情况,以不同熟期的桃树为试材,对这几项技术措施的梨小食心虫防治效果进行了调查。结果表明,刮树皮对越冬代梨小食心虫的防治效果为88.64%,是防治桃地上部梨小食心虫效果最好的技术措施;绑草把诱虫带的防治效果为74.13%,是防治越冬代梨小食心虫最经济、有效的技术措施;3月中旬地表覆土3 cm可阻止土中越冬茧羽化出土;清除地面枯枝可防治地表的越冬幼虫。
Bark scraping, entrapping the trap with insects, cleaning the orchard and covering the soil are the main technical measures to control overwintering pears, but lack of systematic quantitative evaluation and are not widely used in production. In response to this situation, peach trees of different maturities were used as test materials to investigate the prevention and control effects of these pest insects on these technical measures. The results showed that the control effect of scraping bark on overwintering Pear Moth was 88.64%, which was the best technical measure to control pest moth on the top of peach. The control effect of the insecticide was 74.13% The most economical and effective technical measures on behalf of Pear Mungbean; 3 mid-March soil cover 3 cm surface soil can prevent overwintering cocoon eclosion unearthed; clearing the ground dead branches can control the surface of the overwintering larvae.
