豆科豆荚Maruca vitrata（Fablicius）的大量饲养可能是一个非常劳动密集型的过程。为了改善幼虫饲养的省力方法，使用14种饮食方案进行了饲养实验，在早期和后期幼虫阶段之间进行了饮食转换。使用六种不同的半合成日粮，包括四种粗商业日粮。幼虫在以下饲料中的存活率、发育历期和蛹重最高：（1）1 - 2龄-昆虫纲F-II（一种用于食草昆虫的商业半合成饲料，不含桑葚粉）与50%红豆粉混合;（2）第3至第5龄-转换为粗商业饮食，或者Insecta LFS（用于食草昆虫的半合成饮食，含有桑葚粉）或者与10%红豆粉混合的Insecta F-II。在摄食实验中，早期幼虫倾向于选择含有红豆或桑葚粉的饲料，而后期幼虫的摄食偏好是非选择性的。例外的是与50%红豆粉混合的昆虫F-II，其幼虫在释放后24和96 h之间显示出显著高的偏好。
Mass rearing of the legume podborerMaruca vitrata(Fablicius) can be a very labor-intensive process. To improve the labor-saving method for larval raising, rearing experiments were conducted using 14 diet regimens, with and without diet-switching between the earlier and latter larval stages. Six different semi-synthetic diets were used, including four crude commercial diets. Larvae showed the highest performance in survival rate, developmental duration and pupal weight when reared on the following diet regimen: (1) 1st to 2nd instars—Insecta F-II (a commercial semi-synthetic diet for herbivorous insects, containing no mulberry leaf powder) mixed with 50 % azuki bean powder; (2) 3rd to 5th instars—switch to a crude commercial diet, either Insecta LFS (a semi-synthetic diet for herbivorous insects, containing mulberry leaf powder) or Insecta F-II mixed with 10 % azuki bean powder. In the feeding experiments, larvae in the earlier stages tended to prefer diets containing azuki bean or mulberry leaf powder, whereas larvae in the latter stages were non-selective in their feeding preference. The exception was Insecta F-II mixed with 50 % azuki bean powder, for which the larvae showed a significantly high preference between 24 and 96 h following release.
