Four trials were conducted; the first established optimal cooking time for false codling moth diets using a microwave oven while the other three trials aimed at determining nutrient requirements, testing these, and evaluating alternative cheaper raw materials.
Microwave preparation for 8 min, using a 1000 W microwave oven was found to be the optimal cooking time for all treatment diets at 200 g kg moisture. The minimum specification (MS) diet yielded more larvae per jar (mean ± standard deviation) (759 ± 29) than the control (CON) (652 ± 32) diet and the ideal amino acid profile (IAAP) diet (596 ± 46). The third trial subsequently utilized diets formulated according to the MS diet nutrient specifications but using novel and cheaper raw materials (D1 and D2). Production characteristics of diets D1 and D2 was compared to that of CON. Diets D1 and D2 yielded more larvae per jar (D1 = 911 ± 40; D2 = 830 ± 40) than that of CON (428 ± 40) with the added advantage that the newly formulated diets were cheaper.
Reduced cost feeds were formulated, mixed and tested which resulted in substantial saving in the mass rearing of the species for integrated pest management. This method shows potential for diet development of other insect species as well. © 2019 Society of Chemical Industry.
进行了四项试验;第一项试验使用微波炉确定了假苹果蠹蛾饮食的最佳烹饪时间,而另外三项试验旨在确定营养需求、测试这些需求并评估替代更便宜的原材料。
发现,在 200g/kg 水分条件下,使用 1000W 微波炉微波处理 8 分钟是所有处理饮食的最佳烹饪时间。最低规格(MS)饮食每罐(平均值±标准偏差)产生的幼虫(759±29)多于对照(CON)饮食(652±32)和理想氨基酸谱(IAAP)饮食(596±46)。随后,第三项试验利用根据 MS 饮食营养规格制定的饮食,但使用新颖且更便宜的原材料(D1 和 D2)。将饮食 D1 和 D2 的生产特性与 CON 进行了比较。与 CON 相比,饮食 D1 和 D2 每罐产生的幼虫更多(D1=911±40;D2=830±40),并且新配方的饮食更便宜。
制定、混合和测试了降低成本的饲料,这为该物种的综合虫害管理的大规模繁殖节省了大量资金。这种方法也显示出对其他昆虫物种饮食开发的潜力。©2019 化学工业协会。
