法库地区苹果园桃小食心虫防治技术
Control Techniques of Fruit Moth in Apple Orchard in Faku Area

法库县隶属于辽宁省沈阳市，自然地貌特征为“三山一水六分田”，属北温带大陆性季风气候，为半湿润地区，年均气温7.5℃，1月平均气温？12.5℃，1月最低气温？34.4℃ (2001年1月14日)，7月平均气温23.8℃，7月最高气温37.5℃ (2000年7月8日)，无霜期150 d左右，年平均降水量587 mm。气候温和，雨量适中，春秋昼夜温差大，在果树产业中，从2002年以来，法库县重点发展了寒富苹果、鸡心果等，目前保存面积3万余亩。近几年桃小食心虫发生严重，特别是不套袋的鸡心果最重，桃小食心虫蛀果率平均30%~40%，个别园桃小食心虫蛀果率达到80%以上，农民损失惨重，严重制约着法库地区的苹果产量及经济价值。为了摸清桃小食心虫在法库地区的发生规律，我们自然资源与行政执法中心联合农业中心，于2018年、2019年在法库县三个苹果园(含鸡心果)，对桃小食心虫幼虫出土期和成虫发生期进行了测报，2020年、2021年连续两年，根据桃小食心虫法库地区的发生规律，进行了防治，效果显著，现将法库地区桃小食心虫在苹果园、鸡心果园的发生规律及防治方法，总结如下文。
Faku County is subordinate to Shenyang City, Liaoning Province. Its natural landform is character-ized by “three mountains, one water and six fields”. It belongs to the northern temperate continental monsoon climate. It is a semi humid area and the average annual temperature is 7.5？C, the average temperature in January is ？12.5？C, the lowest temperature in January is ？34.4？C (January 14, 2001), the average temperature in July is 23.8？C, the maximum temperature in July is 37.5？C (July 8, 2000), and the frost free period is about 150 days. The average annual precipitation is 587 mm. The climate is mild, the rainfall is moderate, and the temperature difference between day and night in spring and autumn is large. In the fruit industry, Faku County has focused on the development of Hanfu apple and chicken heart fruit since 2002. At present, the preservation area is more than 30,000 mu. In recent years, the occurrence of small peach fruit moths is serious, especially the non-bagged chicken heart fruit is the heaviest. The average fruit decay rate of small peach fruit moths is 30%~40%, and the fruit decay rate of small peach fruit moths in some orchards is more than 80%. Farmers suffered heavy losses, which seriously restricted the apple yield and economic value in Faku area. In order to find out the occurrence law of peach fruit moth in Faku area, the Natural Resources and Administrative Law Enforcement Center together with the Agricultural Center measured and predicted the emergence period of peach fruit moth larvae and adults in three apple orchards (including chicken heart fruit) in Faku County in 2018 and 2019. According to the occurrence law of peach fruit moth in Faku area for two consecutive years in 2020 and 2021, the occurrence law and control methods of peach fruit borer in apple orchard and chicken heart or-chard in Faku area are summarized as follows.
