The Asian citrus psyllid (ACP) Diaphorina citri Kuwayama is an economically important pest of citrus because it vectors the causal pathogens of huanglongbing (HLB) or citrus greening disease. Biological control is an important component of citrus pest management but requires consistent strengthening of its impact on pest complex. The brown lacewing Sympherobius barberi Banks is a known predator of several insect pests from Asia, Europe, and America. However, there is not much information about its effectiveness against D. citri. We evaluated S. barberi against the D. citri and frozen eggs of the Mediterranean flour moth Ephestia kuehniella, the latter is a common diet used for rearing predators in laboratories. Adult S. barberi successfully fed on D. citri eggs and nymphs under both light and dark conditions. Diaphorina citri was also suitable for the development and reproduction of S. barberi except for slightly prolonged larval development compared with E. kuehniella diet. The egg hatch from the total number of eggs laid on D. citri and E. kuehniella diets averaged 65% and 52%, respectively. Females laid 64% eggs on dimpled white paper compared to 36% combined on plain paper and leaves of citrus, orange jasmine, eggplant and cantaloupe. Sympherobius barberi released at densities of 2–6 adults against eggs and nymphs of D. citri on infested orange jasmine plants in the cages provided a reduction of 43–81% in the number of provided eggs or nymphs. In the field tests on D. citri infested citrus trees, reduction averaged 35% in five cohorts in which developing colonies of 28–32 nymphs were provided to one S. barberi per cage. Findings suggest the significant potential of S. barberi as a predator of D. citri and to contribute to reducing huanglongbing.

亚洲柑橘木虱（ACP） 柠檬黄Kuwayama是柑桔的一种重要的经济害虫，因为它是黄龙病（HLB）或柑桔绿化病的病原体的载体。生物防治是柑橘有害生物管理的重要组成部分，但需要不断加强其对有害生物综合体的影响。棕色草lace巴贝小班克斯是亚洲，欧洲和美洲几种害虫的已知捕食者。但是，关于其针对柠檬木。我们评估了巴贝里链球菌 反对这 柠檬木 和地中海面粉蛾的冷冻鸡蛋 肺炎埃希氏菌，后者是用于饲养实验室捕食者的常见饮食。成人巴贝里链球菌 成功喂食 柠檬木 卵和若虫在明亮和黑暗的条件下。 柠檬黄 也适合于 巴贝里链球菌 与相比，幼虫的发育略有延长。 库埃氏菌饮食。从产卵总数中孵出的卵柠檬木 和 库埃氏菌饮食平均分别为65％和52％。雌性在有凹痕的白纸上产下64％的卵，而在普通纸和柑橘，橙子茉莉花，茄子和哈密瓜叶上的产卵率则为36％。巴贝小 以2–6只成虫的密度释放，抵御卵和若虫 柠檬木笼子中侵染的橙色茉莉花上提供的卵或若虫数量减少了43–81％。在现场测试柠檬木 出没的柑橘树，在五个队列中平均减少了35％，其中向一个队列提供了28-32个若虫的发育殖民地 巴贝里链球菌每个笼子。调查结果表明，巴贝里链球菌 作为...的掠食者 柠檬木 并有助于减少黄龙病。
