The melon fly, Zeugodacus cucurbitae (Coquillett), is a serious pest of many fruits and vegetables throughout the world. Here we have developed an easy and quick-to-prepare solid medium with multiple benefits including reductions in post-rearing waste, storage space, and labor for rearing Z. cucurbitae larvae. The development time from egg to pupa was 19.11 d when larvae were reared on the artificial diet, slightly longer than 17.73 d on pumpkin and 17.13 d on cucumber. Zeugodacus cucurbitae achieved higher values of pupal weight, length, and width on the artificial diet than two natural diet controls. The rates of pupation and adult emergence of Z. cucurbitae grown on the solid medium were comparable with those on pumpkin and cucumber. Furthermore, determined by age-specific two-sex life table method, the age-specific survival rate of Z. cucurbitae was higher on the artificial diet than cucumber but lower than pumpkin. The reproductive ability and population dynamics of Z. cucurbitae were not significantly affected on the solid medium compared with those on the two natural diets. The results suggest that our solid artificial diet is excellent for rearing Z. cucurbitae larvae in laboratory and may be used for its mass rearing, therefore facilitating its research and control.

通过两性寿命表评估适合参数的葫芦科(Diptera:Tephritidae)幼虫的新型固体人工饮食。

瓜蝇(Zeugodacus cucurbitae)(Coquillett)是全世界许多水果和蔬菜的严重害虫。在这里,我们开发了一种容易且快速制备的固体培养基,具有多种好处,包括减少育成后的废物,减少存储空间以及饲养葫芦科幼虫的人工。人工喂养时,从卵到的发育时间为19.11 d,比南瓜的17.73 d和黄瓜的17.13 d稍长。与两个自然饮食对照组相比,葫芦形在人工饮食上获得更高的weight重,长度和宽度值。化蛹和羽化率Z. cucurbitae在固体培养基上生长的南瓜与在南瓜和黄瓜上生长的南瓜相当。此外,通过按年龄区分的两性寿命表法确定,人工饮食下葫芦科的按年龄区分的生存率高于黄瓜,但低于南瓜。与两种自然饮食相比,固形培养基对葫芦科的繁殖能力和种群动态没有显着影响。结果表明,我们的固体人工饲料非常适合在实验室饲养葫芦科的幼虫,可用于大规模繁殖,从而有助于其研究和控制。
