摘　　要：为明确桃小食心虫在不同寄主上的发生及转移规律,2021年-2022年在新疆南部荒漠生态区桃小食心虫主要发生区域,利用性诱剂和粘虫板进行桃小食心虫成虫监测及越冬茧分布调查,并于2021年调查了各寄主果园中幼虫为害规律。结果显示,在新疆桃小食心虫越冬代成虫羽化高峰期集中在6月下旬至7月上旬,第一代成虫发生高峰期为8月中旬;桃小食心虫第一代幼虫在蟠桃园为害最严重,越冬代幼虫集中在红枣园为害;桃小食心虫发生与寄主植物的物候期密切相关,越冬幼虫集中在红枣园,越冬代成虫在红枣园羽化后,根据寄主物候期扩散至其他寄主果园内产卵为害。In order to clarify occurrence and transfer regularity of Carposina sasakii in different hosts,the main occurrence area of C.sasakii in the desert ecoregion of southern Xinjiang during 2021-2022 was investigated.C.sasakii adults were monitored with sex attractors and armyworm panels,the distribution of overwintering cocoon,and the regularity of larval damage in orchards of each host in 2021 was investigated.The results showed that the emergence peak of the overwintering generation of C.sasakii in Xinjiang was concentrated in late June to early July,and the peak of the first generation of adults was in mid-August.The larvae of the first generation were most harmful in the peach orchard,and the larvae of the overwintering generation were most harmful in the red date orchard.The occurrence of C.sasakii was closely related to the phenological period of host plants.The overwintering larvae concentrated in the jujube orchard,and the overwintering adults spread to other host orchards to lay eggs according to the phenological period of host plants.
