为建立基于X射线辐照的害虫不育技术,以梨小食心虫2、5、8日龄的雄蛹为研究对象,利用X射线对其进行0(CK)、67、133和200 Gy剂量的辐照处理,明确其最适辐照蛹龄;并对最适辐照蛹龄的梨小食心虫进行X射线辐照,明确辐照处理对其羽化成虫的... 为建立基于X射线辐照的害虫不育技术,以梨小食心虫2、5、8日龄的雄蛹为研究对象,利用X射线对其进行0(CK)、67、133和200 Gy剂量的辐照处理,明确其最适辐照蛹龄;并对最适辐照蛹龄的梨小食心虫进行X射线辐照,明确辐照处理对其羽化成虫的繁殖能力、寿命、飞行能力和交配竞争力的影响。结果表明,梨小食心虫最适辐照蛹龄为8日龄;雄蛹经67 Gy与133 Gy辐照剂量处理后,与其羽化后成虫交配后的雌成虫单雌产卵量分别为25.14粒和24.56粒,卵孵化率分别为18.21%和14.61%,寿命分别为16.80 d和15.60 d,均显著低于对照;梨小食心虫雄蛹辐照处理对其羽化成虫与雌成虫的交配次数无显著影响,但辐照处理雄蛹羽化后的雄成虫与雌成虫交配后,雌成虫的日产卵量比对照明显减少,且辐照剂量越高,日产卵量变化幅度越小,产卵期也越短;辐照处理对雄蛹羽化后雄成虫的飞行能力无明显影响,但其与雌成虫的交配竞争指数下降为0.15。 展开更多

Methyl-eugenol (ME) (1,2-dimethoxy-4-(2-propenyl)benzene), a natural phy- tochemical, did enhance male Bactrocera carambolae Drew & Hancock (Diptera: Tephri- tidae) mating competitiveness 3 d after ingestion. Enhanced male mating competitiveness can significantly increase the effectiveness of the sterile insect technique (SIT). ME appli- cation to mass reared sterile flies by feeding is infeasible. ME application by aromatherapy however, would be a very practical way of ME application in fly emergence and release facilities. This approach was shown to enhance mating competitiveness ofB. carambolae 3 d posttreatment (DPT). Despite this added benefit, every additional day of delaying re- lease will reduce sterile fly quality and will add cost to SIT application. The present study was planned to assess the effects of ME-aromatherapy on male B. carambolae mating competitiveness 1DPT and 2DPT. ME aromatherapy 1DPT or 2DPT did enhance mating competitiveness of B. carambolae males whereas ME feeding 1DPT and 2DPT did not. Male mating competitiveness was enhanced by the ME aromatherapy irrespective if they received 1DPT, 2DPT or 3DPT. ME aromatherapy, being a viable approach for its applica- tion, did enhance mating competitiveness of male B. carambolae 1 d posttreatrnent as ME feeding did 3 d after ingestion. 展开更多
