The aim was to evaluate the effect of different energy diets available in adulthood on the longevity, dispersal capacity and sexual performance of produced under a mass-rearing system. To evaluate the effects of diets in relation to the survival of the adult male insects of , six treatments were used: sucrose at a concentration of 10%, as a positive control (sack10); starvation, as a negative control (starvation); sucrose at a concentration of 20% associated with 1 g/l of ascorbic acid (sac20vitC); wild honey in a concentration of 10% (honey10); demerara sugar in a 10% concentration (demerara10); and sucrose at a concentration of 20% associated with 1 g/l of ascorbic acid and 0.5 g/l of amino acid proline (sac20vitCPr). Each treatment had 16 cages containing 50 adult males. For the tests of flight ability and propensity to copulation, five treatments were used (saca10; sac20vitC; mel10; demerara10; and sac20vitCPr), with males each for flight ability and females copulated by a single male for copulation propensity. The diet composed of sucrose at a concentration of 20% associated with ascorbic acid, as an antioxidant, improved the survival, flight ability and propensity to copulate in males under mass-rearing conditions, and may be useful to enhance the performance of sterile males, thus improving the success of sterile insect technique programmes.
本研究旨在评估成年期不同能量饮食对大规模饲养系统下生产的 寿命、扩散能力和性表现的影响。为了评估饮食对成年雄性昆虫生存的影响，共使用了 6 种处理方法：10%浓度的蔗糖作为阳性对照（sack10）；饥饿作为阴性对照（starvation）；20%浓度的蔗糖与 1 g/L 抗坏血酸（sac20vitC）混合；10%浓度的野生蜂蜜（honey10）；10%浓度的红糖（demerara10）；20%浓度的蔗糖与 1 g/L 抗坏血酸和 0.5 g/L 脯氨酸（sac20vitCPr）混合。每个处理有 16 个笼子，每个笼子里有 50 只雄性成虫。对于飞行能力和交配倾向的测试，使用了 5 种处理方法（saca10；sac20vitC；mel10；demerara10；和 sac20vitCPr），每种处理方法都有 50 只雄性成虫用于飞行能力测试，每只雌性成虫与 1 只雄性成虫交配以测试交配倾向。由 20%浓度的蔗糖与抗氧化剂抗坏血酸组成的饮食，改善了大规模饲养条件下雄性 的生存、飞行能力和交配倾向，可能有助于提高不育雄虫的性能，从而提高不育昆虫技术计划的成功率。
