DelicatulaLycorma,白色(半翅目:Fulgoridae),有斑点的灯笼,是一个单电压,韧皮部喂养,多食和入侵昆虫在美国。尽管该物种的主要宿主是Ailanthusaltissima,天堂之树,L.delicatula也以对美国很重要的多种寄主为食,包括栽培的葡萄。由于需要经典或增强的生物控制计划,以减少黑斑乳杆菌在入侵地区的影响,我们为这种入侵物种制定了基于实验室的饲养方案.这里,我们评估了A.altissima顶端分生组织的使用,表皮芽,和从A.altissima切下的新鲜叶子,作为饲养新孵化的L.delicatula的食物来源。在这些植物材料来源上,<20%的白蚁乳杆菌发育成虫,没有产卵。然而,年轻时,盆栽A.altissima树被用作食物来源,>50%的delicatula若虫在20-25°C的自然日长和温度范围内发育到成虫阶段。添加野生葡萄,黑葡萄,没有增加生存率或减少发育时间。为了引发交配和产卵,向成年人提供A.altissima原木作为产卵基质,并在缩短的日间和降低的夜间温度下维持(12L:12D和24°C:13°C)。这导致每个雌性沉积2.12个卵团,比在标准饲养条件(16L:8D和25°C)下维持成人时增加4倍。基于这些实验,我们提出了一种在实验室和/或温室条件下可靠地饲养delicatula的方案。
Lycorma delicatula, White (Hemiptera: Fulgoridae), spotted lanternfly, is a univoltine, phloem-feeding, polyphagous and invasive insect in the USA. Although a primary host for this species is Ailanthus altissima, tree of heaven, L. delicatula also feeds on a wide range of hosts important to the USA including cultivated grapevines. Due to the need for classical or augmentative biological control programs to reduce impacts of L. delicatula across invaded areas, we developed a laboratory-based rearing protocol for this invasive species. Here, we evaluated the use of A. altissima apical meristems, epicormic shoots, and fresh foliage cut from A. altissima as a food source for rearing newly hatched L. delicatula. On these sources of plant material <20% of L. delicatula developed into adults and no oviposition occurred. However, when young, potted A. altissima trees were used as a food source, >50% of L. delicatula nymphs developed to the adult stage under natural daylengths and temperatures ranging from 20-25°C. The addition of wild grapevine, Vitis riparia, did not increase survivorship or reduce development time. To elicit mating and oviposition, adults were provided with A. altissima logs as an oviposition substrate and maintained under shortened daylengths and reduced nighttime temperatures (12L:12D and 24°C:13°C). This resulted in 2.12 egg masses deposited per female, which was 4× more than when adults were maintained in standard rearing conditions (16L:8D and 25°C). Based on these experiments, we present a protocol for reliably rearing L. delicatula under laboratory and/or greenhouse conditions.
