Abstract The lesser mealworm, Alphitobius diaperinus (Panzer), is a serious pest, but at the same time has been authorized in European Union (EU) for feed in aquaculture. In this study, we investigated, in laboratory bioassays, the population growth of this species, on a wide variety of commodities. In four series of bioassays, we studied the development of A. diaperinus population on various intact cereal grains, on soft wheat grains with different percentages of cracked kernels, on non-grain amylaceous commodities and on a variety of non-amylaceous commodities. Briefly, 20 g of each commodity were put separately inside plastic cylindrical vials.Then, 20 A. diaperinus adults were placed inside each vial and all vials were incubated at 30°C and 55% r.h. After 30 d, the vials were opened and the progeny production was evaluated. Alphitobius diaperinus showed a clear preference in amylaceous commodities, but in contrast, poor development was recorded on the non-amylaceous commodities tested. Hence, it developed well in most of the cereal intact grains tested, with the hard and soft wheat being the most suitable. Additionally, most non-grain amylaceous commodities were suitable, to a various degree, for the population growth of A. diaperinus.The increase of the percentage of cracked wheat positively affected the population growth of A. diaperinus.To our knowledge, this is the first study that examined the suitability of a wide range of commodities for the population growth of A. diaperinus.

Alphitobius diaperinus（鞘翅目：Tenebrionidae）在各种商品上的种群增长

摘要 小型粉虫Alphitobius diaperinus (Panzer)是一种严重的害虫，同时已被欧盟(EU)批准用于水产养殖饲料。在这项研究中，我们在实验室生物测定中调查了该物种在各种商品上的种群增长。在四个系列的生物测定中，我们研究了 A. diaperinus 种群在各种完整谷物、具有不同碎粒百分比的软小麦、非谷物淀粉类商品和各种非淀粉类商品上的发展。简而言之，将20 g每种商品分别放入塑料圆柱瓶中。 然后，将20只A. diaperinus成虫放入每个小瓶中，所有小瓶在30°C和55% rh下孵育30天后，打开小瓶，对后代生产进行了评估。Alphitobius diaperinus 对淀粉类商品表现出明显的偏好，但相比之下，所测试的非淀粉类商品的发育不良。因此，它在大多数测试的谷物完整谷物中发育良好，其中硬质和软质小麦最适合。此外，大多数非谷物淀粉类商品在不同程度上适用于 A. diaperinus 的种群增长。小麦裂化率的增加对 A. diaperinus 的种群增长产生了积极影响。据我们所知，这是第一项研究检查了广泛的商品对 A. diaperinus 种群增长的适用性。它在大多数测试的谷物完整谷物中发育良好，最适合硬质和软质小麦。此外，大多数非谷物淀粉类商品在不同程度上适用于 A. diaperinus 的种群增长。小麦裂化率的增加对 A. diaperinus 的种群增长产生了积极影响。据我们所知，这是第一项研究检查了广泛的商品对 A. diaperinus 种群增长的适用性。它在大多数测试的谷物完整谷物中发育良好，最适合硬质和软质小麦。此外，大多数非谷物淀粉类商品在不同程度上适用于 A. diaperinus 的种群增长。小麦裂化率的增加对 A. diaperinus 的种群增长产生了积极影响。据我们所知，这是第一项研究检查了广泛的商品对 A. diaperinus 种群增长的适用性。
