小绿盲蝽（半翅目：盲蝽科）以白蝇等害虫为食，在许多温室中作为生物防治剂。然而，这种模式在应用上是有限的，因为个体往往会逃离农田，并很快因缺乏可用的食物来源而死亡。此外，传统上用来培养棘球蚴的食物也很昂贵。因此，确定低成本的食物将有助于提高该物种的进一步利用。卤虾（Artemia spp., Anostraca: artemiae）囊是潜在的有用的低成本替代食物，以维持捕食性天敌的种群。本研究评估了在盐渍蒿（Artemia salina L.）囊中饲养的黄颡鱼的发育和繁殖性能。干包囊表现出与地中海粉蛾（Ephestia kuehniella Zeller，鳞翅目：皮蛾科）卵相似的性状，后者常被用作大规模饲养黄颡鱼的营养饲料。虽然湿囊有助于生长，但与其他饮食相比，它们在若虫发育时间和寿命方面都较差。这些结果表明，相对便宜的青蒿干囊可用于成功地培育和维持作物田间种群。
The small green mirid Nesidiocoris tenuis Reuter (Hemiptera: Miridae) preys on pest insects such as whiteflies and serves as a biological control agent in many greenhouses. However, this mirid is limited in its application, because individuals tend to escape from agricultural fields and soon die due to a lack of available food sources. In addition, the food traditionally used to culture N. tenuis is expensive. Thus, identifying low-cost foods for N. tenuis would help to increase the species' further utilization. Brine shrimp (Artemia spp., Anostraca: Artemiidae) cysts are potentially useful as a low-cost alternative diet to sustain populations of predatory natural enemies. We evaluated the developmental and reproductive performance of N. tenuis when reared on Artemia salina L. cysts supplied in dry or wet form. The dry cysts showed a similar performance to that of Mediterranean flour moth (Ephestia kuehniella Zeller, Lepidoptera: Pyralidae) eggs, which are often used as a nutritional diet for mass rearing of N. tenuis. Although the wet cysts contributed to growth, compared to other diets, they were inferior in nymphal development time and longevity. These results suggest that relatively inexpensive Artemia dry cysts can be used to successfully breed N. tenuis and sustain populations in crop fields.
