入侵海南18个市县草地贪夜蛾的遗传分析与分子鉴定
Genetic analysis and molecular identification of Spodoptera frugiperda invading into eighteen counties in Hainan
摘要
Abstract
[Aim]Spodoptera frugiperda is a major migratory agricultural pest that is native to the tropical and subtropical regions of the Americas.Hainan is one of the source areas of this pest for migration in China.Revealing the biotypes and genetic characteristics of S.frugiperda in Hainan will be beneficial for monitoring and prevention of this pest in Hainan and even China.[Method]Two mo-lecular markers,the mitochondrial gene COⅠand the nuclear gene Tpi,were used for identification and genetic characterization of 76 samples from corn plants in Hainan.[Result]According to COⅠsequences,76.3%of samples were the rice strain and 23.7%were the corn strain.According to Tpi sequences,most samples were the corn strain,and there might be hybrids of rice and corn strains.The phylogenetic tree built based on COⅠ indicated that S.frugiperda in Hainan has the same COⅠ sequence as those in Guangdong(China),Florida(USA),and South Africa.[Conclusion]This study clarifies the biotypes and distribution of S.frugi-perda in Hainan,providing a reference for early monitoring,warning,and precise control of this pest in Hainan.关键词
