细盲蝽（Nesidiocoris tenuis，罗伊特）（半翅目：盲蝽科）是一种植食性捕食性天敌，广泛应用于温室和露地番茄作物的害虫综合治理。N.细叶螟的食物来源主要是斑螟Ephestia kuehniella Zeller卵。此外，在接种N.建议在实地条件下使用tenuis，以促进建立这一mirid。然而，E. Kuehniella卵价格昂贵且可获得性有限。减少E. kuehniella鸡蛋需要的是糖的供应。本文研究了蔗糖作为营养添加剂对红腹锦鸡儿部分生活史性状的影响。研究了薄。在E. kuehniella卵显著增加了N. tenuis，不影响胚胎的存活和发育时间。此外，蔗糖的添加显著降低了E. kuehniella卵消耗。这些结果可能具有实际意义的兴趣，大量饲养系统的N。tenuis及其在田间和温室中的管理，作为生物控制计划的一部分。
Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae) is a zoophytophagous predator widely used in integrated pest management programs in both greenhouse and open-field tomato crops. Mass rearing of N. tenuis is greatly dependent on Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) eggs as food source. Moreover, the addition of this factitious prey after the inoculative releases of N. tenuis under field conditions is recommended to facilitate establishment of this mirid. However, E. kuehniella eggs are expensive and availability is limited. One possible strategy to reduce the amount of E. kuehniella eggs needed is the provision of sugar. In this work, the effect of sucrose as nutritional supplement on selected life-history traits of N. tenuis was studied. The addition of sucrose (0.5 M) ad libitum to a diet of E. kuehniella eggs significantly increased the progeny of N. tenuis and did not affect survival of nymphs nor developmental time. Moreover, addition of sucrose significantly reduced the number of E. kuehniella eggs consumed. These results may have practical implications of interest in mass rearing systems of N. tenuis and its management in fields and greenhouses as a part of biological control programs.
