| 摘 要： | 通过２ａ的调查结果表明，豫北地区苹果树干皮缝中越冬的节肢动物数量大，且种类繁多，其中包括农林作物和果树害虫及其天敌。统计分析表明，害虫占总数的８．３４％，天敌占总数的９１．６６％，蜘蛛类占天敌总数的４５．４５％，传统的冬季刮老树皮防治果树害虫的方法，能消灭部害虫，也能杀伤大量的害虫天敌、建议尽量不要刮树干老皮。

| Abstract: | A great number of and many species of the overwintering arthropods, including the pests in farming ,foresty ,fruit trees and their natural enemies, have been found inside the cracks of the stems of apple trees after two years' investigation in the north of Henan Province. It has been shown by statistical analysis that pests total 8.34%, natural enemies 91.66%; Among the natural enemies, spiders total 45.45%. Consequently, although the tradition of scraping off the old bark of a tree can eliminate part of the pests,it can also kill a lot of natural enemies. We advise against scraping off the old bark of a tree by all means. |
