Investigation on egg parasitoids of Chilo sacchariphagus Bjojer in sugarcane planting areas of central and south Guangxi
摘要
Abstract
[Objective]Dominant egg parasitoid types and their growth situations of Chilo sacchariphagus Bjojer in sugarcane growing areas of Guangxi were determined to provide references for safeguarding superior natural enemies and artificially controlling Chilo sacchariphagus Bjojer. [Method]Egg parasitoid types and its dominant species of Chilo sacchariphagus Bjojer were investigated using field sampling and indoor breeding in typical sugarcane planting areas including Wuxu Town of Nanning City, Laituan Town of Chongzuo City and Wuxuan County of Laibin City. [ Result ] The results showed that there were mainly two kinds of egg parasitoids, Trichogramma chilonis Ishii and Telenomus sp., in three sugarcane planting areas. The parasitic rate of Telenomus sp. in egg-masses and eggs of Chilo sacchariphagus Bjojer in Laituan Town of Chongzuo City was 52.11 and 45.32%, respectively, and that of Trichogramma chilonis was 19.72 and 17.04%, respectively. In Wuxuan County of Laibin City, the parasitic rate of Telenomus sp. in egg-masses and egg was 1.79 and 2.40%, and that of Trichogramma chilonis was 8.93 and 6.29%, respectively. And in Wuxuan Town of Laibin City, the parasitic rate of of Telenomus sp. in egg-masses and eggs was 5.13 and 6.36% , and that of Trichogramma chilonis was 43.59 and 41.75%, respectively. [Conclusion]Telenomus sp. was the dominant natural parasitical enemy of Chilo sacchariphagus Bjojer in Laituan Town of Chongzuo City, while · Trichogramma chilonis was the dominant natural parasitical enemy in Wuxuan Town of Laibin City and Wuxu Town of Nanning City.关键词
