从形态、寄主、食性、生物学和生物防治 5个方面概述了新害虫蔗扁蛾 Opogona sacchari( Bojer)在国内的研究进展。在广州及其周边地区已发现有 17种植物不同程度地受蔗扁蛾为害 ,11种是首次记录的寄主植物。蔗扁蛾的食性十分复杂 ,有钻蛀性、腐食性和杂食性等。完成 1个世代需要 60～ 12 1d,全年可发生 4代 ;幼虫 7龄 ,历期长达 37～ 75d,成虫在羽化前 ,蛹的头胸部露出蛹壳 ,约 1d后成虫羽化 ;羽化后的成虫喜暗 ,羽化 4～ 7d后产卵 ,产卵量为 2 53.0 5± 65.18。昆虫病原线虫能有效防治蔗扁蛾幼虫 The research progress of Opogona sacchari (Bojer) in China from five aspects of morphology, host, feeding habits, biology and biological control were summarized. In Guangzhou and its surrounding areas, 17 species of plants have been found to be affected to varying degrees by the sugarcane family, 11 species being the first recorded host plants. The infestation of sugarcane moth is very complex, with borers, rotten and omnivorous. It takes 60-12 days to complete 1 generation and 4 generations to occur throughout the year. The larvae are 7 years old and have a long duration of 37-75 days. Before adult emergence, pupae show pupae shell in their head and chest, and emerge about 1 d later. After eclosion Of adult hi dark, emergence 4 ~ 7d after oviposition, fecundity of 2 53.0 5 ± 65.18. Entomopathogenic nematodes can effectively control the larvae of
