delicatula in large numbers as they exploit the insect’s negative gravitactic dispersal behavior, but they result in significant non-target captures ( Nixon et al. These sticky bands were effective at capturing L. delicatula were monitored in the United States using brown sticky bands affixed around the trunk of host trees ( Francese et al. Concerns for continued range expansion and damage to specialty crops, such as Vitis spp., ornamental plants, and forestry trees have led to eradication efforts including removal of tree of heaven, foliar and systemic insecticide trunk treatments, and biosurveillance programs based on deploying monitoring traps on favored host plants in high-risk transportation areas ( Parra et al. delicatula produce copious amounts of honeydew as they feed which coats the host and surrounding plants and propagates the growth of black sooty mold which contributes to plant decline ( Han et al. 2019) and the United States ( Leach et al. delicatula can result in decreased health for the host plant: damage on economically important crops such as grape and peach ( Prunus persica (L.) Batsch) have been reported in South Korea ( Han et al. Lycorma delicatula are highly polyphagous, feeding on a broad range of hosts common to the mid-Atlantic region of the United States including Ailanthus altissima (Mill.) Swingle (tree of heaven), Juglans nigra L. Nymphs develop through the spring and summer months with adults beginning to emerge in July, and oviposition beginning in September in the United States. delicatula overwinters as egg masses with first hatch occurring in mid-Spring ( Lee et al. Lycorma delicatula is univoltine, with a phenology that, thus far, follows the same developmental pattern between its native and invaded ranges: L.
2021), and predictive models show that much of the United States is climatically suitable for this species’ establishment ( Jung et al.
Lycorma delicatula continues to be detected in new regions despite concerted eradication and public outreach efforts ( Urban et al. 2015) and populations have since spread and established across numerous Eastern states (). It was first detected in the United States in 2014 in Berks County, PA ( Barringer et al. Lycorma delicatula (White) (Hemiptera: Fulgoridae), commonly called spotted lanternfly, is a polyphagous fulgorid native to China, India, and Vietnam ( Lee et al. Spotted lanternfly, monitoring, invasive species, circle traps Introduction We were also able to alter the construction of circle trap skirts to allow for deployment on different sized tree trunks. delicatula at most sites, traps deployed on other hosts also yielded consistent captures. Although traps deployed on Ailanthus altissima (Mill.) Swingle (Sapindales: Simaroubaceae) captured significantly or numerically more L. While no significant differences in captures were found among intervals, weekly or biweekly sampling prevented specimen degradation. Traps deployed 1 m from the ground captured significantly more adults than those deployed at 0.5 m no differences were detected for nymphs. delicatula adults at low-density sites compared with other trap types in 2021, and no differences were detected at high-density sights. Circle traps captured significantly more L. Trap deployment at different heights and on different host tree species and trap sampling intervals were evaluated for standard circle traps only. Standard circle traps, sticky bands, and circle traps with replaceable bag tops were deployed at sites with either high or low populations present. Here, we compared deployment strategies to optimize use of L. delicatula is essential to develop pest management tools. Monitoring presence and relative abundance of L. This phloem-feeding pest has a broad host range, including economically important crops such as grapevine, Vitis spp. The spotted lanternfly, Lycorma delicatula (White) (Hemiptera: Fulgoridae), is an invasive planthopper that was first detected in the United States in Berks County, PA, in 2014, and has since spread to 13 states in the Eastern United States.
