摘要
已有研究表明，香梨优斑螟Euzophera pyriella对糖醋液有强烈的正趋性，而成虫取食糖类等补充营养对其寿命和生殖力的影响未见报道。本文在实验室条件下，研究了香梨优斑螟成虫取食10％蜂蜜水、5％蜂蜜水、5％蔗糖水、5％香梨汁、糖醋酒液（白砂糖：食用醋：酒：水：2：3：1：11）和水共6种处理食物作为补充营养及饥饿条件下的存活寿命和生殖能力。结果表明：补充不同的营养对香梨优斑螟雌成虫产卵前期和产卵期的影响程度不同，10％蜂蜜水作为补充营养较好，可显著缩短卵的形成时间，延长产卵期；从补充营养对单雌产卵量和卵孵化率以及成虫寿命的影响看，香梨优斑螟成虫取食10％蜂蜜水、5％蜂蜜水和糖醋酒液时单雌产卵量较高，最高可达71．63粒，说明产卵量的多少与补充营养密切相关。
Previous studies have shown the mixture of sugar-aceticacid-ethanol has strong taxis to of Euzopherapyriella, but no research oneffects of different supplementary nutrients on adult＇s longevity and reproduction of adult were reported.The repro- duction and longevity of adults fed on 10% honey solution,5% honey solution,5% glucose solution,5% Pear juice solution,the mixture of sugar-aceticacid-ethanol （sugar：vinegar：wine：water = 2：3：1：11） and distilled water were investigated in labo-ratory. The results showed that the supplementary nutrients had significant effects on adult reproduction and longevity.The treatment fed on 10%honey-water solution had the shortest pre-oviposition period and the longest period of spawningthan other treatments.From the effects of supplementary nutrition on egg number one femaleand egg hatching rateadult＇s longevityandreproduction ,the extraor-dinary egg laying amount appeared in the treatment fed on 10% honey-water solution,5% honey-water solution and sugaraceti-cacid ethanol solution,which wereup to 71.6/female.It means thatthesupplementary nutrients had obvious effects on the number of laying eggs of E.pyriella.
