丰年虾的脱壳包囊被评估为饲养花环虫捕食者 Orius laevigatus 的人造食物。比较了在来自三个地理位置的 A. franciscana 或地中海面粉蛾 Ephestia kuehniella 的伽马辐射卵上饲养单代的 O. laevigatus 的发育和繁殖特征。饮食对若虫存活率没有影响，但 E. kuehniella 卵的若虫期（12.2 天）比卤虫饮食短 0.7 - 1.6 天。捕食者在来自旧金山湾（美国）的包囊上的发育速度比在来自大盐湖（美国）或澳门（巴西）的包囊上的发育速度快 0.5 - 1 天。不同地点的丰年虾包囊的繁殖力与粉蛾卵的繁殖力相似（142 - 187 卵/雌性）。将来自旧金山湾的脱囊包囊的生化成分与 E. kuehniella 卵的生化成分进行了比较。根据分析类型，与 E. kuehniella 卵相比，卤虫包囊含有更高或相似数量的蛋白质，但氨基酸模式总体相似。粉蛾卵的脂肪酸含量几乎是丰年虾囊肿的三倍，但脂肪酸谱存在一些显着差异。由于饮食中的营养失衡可能只有经过几代饲养后才会表现出来，因此捕食者在来自旧金山湾的 A. franciscana 包囊上连续培养了三代。在丰年虾包囊的第三代中，若虫的发育时间比 E. kuehniella 卵上的幼虫要长 18%，成虫的寿命很短，繁殖力也比 E. kuehniella 卵少约 60%。丰年虾包囊可用作大量生产光虾的补充剂，但可能不适合长期培养捕食者。
Decapsulated cysts of the brine shrimp Artemia franciscana were assessed as a factitious food for rearing the anthocorid predator Orius laevigatus. Developmental and reproductive traits of O. laevigatus reared for a single generation on A. franciscana from three geographical locations or on gamma- irradiated eggs of the Mediterranean flour moth Ephestia kuehniella were compared. There was no effect of diet on nymphal survival but nymphal period on E. kuehniella eggs ( 12.2 days) was 0.7 - 1.6 days shorter than on the Artemia diets. The predator developed 0.5 - 1 day faster on cysts from San Francisco Bay ( USA) than on cysts from Great Salt Lake ( USA) or Macau ( Brazil). Fecundity on brine shrimp cysts from different locations was similar to that on flour moth eggs ( 142 - 187 eggs/ female). The biochemical composition of decapsulated cysts from San Francisco Bay was compared with that of E. kuehniella eggs. Depending on the type of analysis, Artemia cysts contained higher or similar amounts of protein as compared with E. kuehniella eggs, but amino acid patterns were generally similar. Flour moth eggs were almost three times richer in fatty acids than brine shrimp cysts, with some marked differences in fatty acid profiles. Because nutrient imbalances in a diet may be expressed only after several generations of rearing, the predator was cultured for three consecutive generations on A. franciscana cysts from San Francisco Bay. In the third generation on brine shrimp cysts, nymphs took 18% longer to develop, and adults were shorted- lived and about 60% less fecund than those maintained on E. kuehniella eggs. Brine shrimp cysts may be used as a supplement in the mass production of O. laevigatus but may not be a suitable food for long- term culturing of the predator.
