香蕉假茎象甲实验种群生命表的组建

Life tables of the banana pseudostem weevil,Odoiporus longicollis population in laboratory.

研究结果表明取食不同香蕉品种的香蕉假茎象甲雌成虫产卵量有一定差异。以取食广东香蕉2号、泰国蕉和孟加拉龙牙蕉的雌成虫产卵量较高。取食巴西蕉、粉蕉和Saba大蕉产卵量较少。以广东香蕉 2号、泰国香蕉和孟加拉龙牙蕉等香蕉品种假茎为食料的香蕉假茎象甲实验种群趋势指数较大 ,以巴西香蕉为食料的较小 ,以粉蕉。

The life table of banana pseudostem weevil population was constructed in laboratory when it fed on different banana varieties. The female could lay more eggs when fed on Gungdong banana II, Thailand banana, Bengal AAB cavendish than that on Brazil banana (AAA cavendish) and Saba banana Fen banana(ABB cavendish).The trend indices of the weevil laboratory populations fed on Guangdong banana II, Thailand banana, Bengal AAB cavendish, Brazil banana, and Fenbanana, Saba banana, were 10.51, 10.87, 9.56, 8.25, 6.98, 6.81, respectively.
