河南省具条实蝇种群动态监测

Inspection of population dynamics of Bactrocera scutellata (Hendel) in Henan Province

利用诱蝇醚(Methyleugenol)、诱蝇酮(Cuelure)和水解蛋白(Hydrolytic protein)3种诱剂监测了河南省25个区县共计80个实蝇监测点实蝇的分布与发生动态.结果表明,在河南省25个区县共诱集到具条实蝇Bactrocerascutellata(Hende1)4 157头,具条实蝇是河南的优势实蝇种群,其他种类实蝇极少.其中洛阳、商丘、南阳诱集的具条实蝇数量大均在500头以上,是该虫发生严重的区县.具条实蝇一年发生代数因地区而不同,在河南省山区发生1代,平原发生2代,种群羽化较整齐,在7月中下旬至8月上中旬有1个虫口高峰期.对3种诱剂诱集数量统计分析发现,不同诱剂在每个监测点诱集到的实蝇平均数量无显著性差异.

The quantity dynamics and distribution of Bactrocera scutellata （Hendel） were monitored with methyleugenol, cuelure and hydrolytic protein as luring agents in 25 counties of Henan Province in 2008. The number of the fruit flies collected were 4 157, and the results showed B. scutellata was dominant species. The average number of the fruit flies collected was larger in the counties of Luoyang, Shangqiu and Nanyang, but smaller in the counties of Luohe, Pingdingshan, Xinxiang and so on. A single peak of its population appeared between July and August in the counties. The three luring agents showed no significant difference in the pest number they lured.
