The use of the blow fly as a potential pollination species to augment the current reliance on honeybees () in Australian horticulture requires knowledge of how best to mass-rear this fly species. lays eggs onto carrion soon after death, and the resultant larvae that hatch are necrophagous and feed on the decomposing tissues of the dead animal. Newly hatched larvae of this fly were provided with plant-based meals (soya bean and canola) and compared with larvae provided with livestock-derived meatmeal to determine if plant-based meal could be used to mass-rear this blow fly species. Both soya bean and canola meal media did not support larval survival through to adult emergence. The addition of only 10% whole egg powder to the plant-based meals enabled survival to eclosion of 39% and 13% on soya bean and canola-based media, respectively, compared with 76% on livestock-based meatmeal with 10% whole egg powder. Larvae fed a diet of livestock-based meatmeal with 10% whole dried egg powder had the fastest development to the pupal stage, the highest pupation rate, the heaviest pupae, and the highest subsequent adult eclosion. This study concluded that the use of plant-based meals as a diet for the mass-rearing of the blow fly was not a viable option.
在澳大利亚园艺业中，利用丽蝇作为一种潜在的授粉物种来减少当前对蜜蜂（ ）的依赖，这需要了解如何最好地大规模饲养这种蝇类。丽蝇在动物死亡后不久便会在腐肉上产卵，孵化出的幼虫是食腐性的，以死去动物的腐烂组织为食。为这种蝇类新孵化出的幼虫提供植物性饲料（大豆和油菜籽），并与以家畜来源的肉粉为饲料的幼虫进行比较，以确定植物性饲料是否可用于大规模饲养这种丽蝇。大豆和油菜籽粕培养基都无法支持幼虫存活至成虫羽化。在植物性饲料中仅添加10%的全蛋粉，能使以大豆和油菜籽为基础的培养基上分别有39%和13%的幼虫存活至羽化，而在添加了10%全蛋粉的家畜来源肉粉培养基上这一比例为76%。以添加了10%全干蛋粉的家畜来源肉粉为食的幼虫发育至蛹期的速度最快，化蛹率最高，蛹最重，随后的成虫羽化率也最高。本研究得出结论，使用植物性饲料大规模饲养丽蝇并非可行选择。
