“…and 61.8% ± 6.8 S.E, respectively. Although the temperatures near ground level over the paved parking lot were noticeably higher than the average ambient air temperatures, females in the parking lot took flight spontaneously within a few minutes and flew for comparable durations and distances as those we observed in other studies in which flights occurred over vegetation (c.f., Wolfin et al 2019;Myrick and Baker 2019;Baker et al 2019).…”

“…Ninety-five percent of the females that take flight spontaneously like this are unmated, weigh less, and have smaller abdomens than sedentary, mated females (Wolfin et al 2019). Flightdispersing females, including the 5% that have mated, are thin and not fully physiologically developed, and after landing they engage in feeding-related behaviors (Baker et al 2019;Wolfin et al 2019). In a commercial apple orchard and vineyard bordered by wood-rows, adults traveled an average of only 24 m in single flight-bouts between the three different crops, with the flight-bout durations lasting only a few tens of seconds (Wolfin et al 2019).…”

“…The host preference of this insect changes with its phenology, as nymphal instars may feed on a broad range of plant species, and adults may feed on a narrower range (Kim et al 2011). Previous studies of the flight dispersal behavior indicated that adult males and females launch themselves into the wind from elevated locations such as trees, poles, and buildings, and travel along low-altitude (< 10 m), descending flight paths for only 10-50 m before landing (Baker et al 2019;Myrick and Baker 2019;Wolfin et al 2019). The insects then crawl up high in new trees, on posts, or other vertical structures and again launch themselves in another bout of flight.…”

“…These will be important determinants of how far a locally dispersing adult spotted lanternfly can move before finding a tree on which to feed and attain physiological maturity and mate. It is conjectured that the interval between flight-boutsthe "flight-bout interval"could be tens of minutes, perhaps hours (Baker et al 2019;Wolfin et al 2019) because adults need to sample the substrate they have landed on (i.e. plants, fence posts, houses, etc.).…”

Flight Duration Capabilities of Dispersing Adult Spotted Lanternflies, Lycorma delicatula

Adult spotted lanternflies, Lycorma delicatula, launch themselves into the wind from elevated locations such as trees, lamp posts, and buildings. Individuals fly in short, successive bouts along descending trajectories of between 10 and 50 m before landing, crawling upward on a new structure, and again launching upwind. The possible physiological limits to the durations of flight-bouts, if not constrained by their poor ability to generate lift, however, remain unknown. In this study, we observed the behavior of tethered spotted lanternflies known to be prone to flight-dispersing, and recorded the number and durations of their successive flight bouts. Additionally, we recorded the flight distances and durations of similar spotted lanternflies in the field that had spontaneously taken flight or had been manually launched. We found that tethered females can perform >20 successive bouts with only 1 min between bouts when flight durations were limited to 20 s/bout. Bouts averaged 97.9 ± 11.4 s when bout durations were unlimited, with some females flying bouts lasting >400 s. Females could quickly advance upwind a distance >3000 m if the bouts of~100 s each were performed in quick succession in the field. However, adults spontaneously taking flight in the field flew for an average of only~13 s and traveled an average of 29 m before landing on the ground or on nearby objects. This information is important to determine how far a locally dispersing adult can fly before finding a suitable host to finish feeding and attain reproductive maturity.

“…Previous studies on sap-feeding insects, other than L. delicatula, showed that issues with molecular approaches still can be overcome, and a portion of various regions of the chloroplast DNA can be successfully detected in insect gut contents [16][17][18]. To date, many studies on the L. deliculata feeding preferences have used behavioral or observational approaches [2,3,8,9,19], whereas the protocols for the detection of plant DNA in the lanternfly gut contents are not yet available from literature. Meanwhile, more information on L. delicatula biology, behavior, and host range is urgently needed for its effective management [9].…”

Spotted lanternfly, Lycorma delicatula (Hemiptera: Fulgoridae), is an introduced highly invasive insect pest in the US that poses a significant risk to forestry and agriculture. Assessing and predicting plant usage of the lanternfly has been challenging, and little is known regarding the lanternfly nymph association with its host plants. In this study, we focused on: (a) providing a protocol for using molecular markers for food plant identification of L. delicatula; (b) determining whether the ingested plant DNA corresponds with DNA of the plants from which the lanternfly was collected; and, (c) investigating the spectrum of ingested plants. We utilized gut contents of third and fourth instar nymphs that were collected from multiple plants; we isolated ingested plant DNA and identified consumed plants. We demonstrated that (a) up to 534 bp of the rbcL gene from ingested plants can be detected in L. delicatula guts, (b) ingested plants in ~93% of the nymphs did not correspond with the plants from which the nymphs were collected, and (c) both introduced and native plants, as well as woody and non-woody plants, were ingested. This information will aid effective the monitoring and management of the lanternfly, as well as predict the lanternfly host plants with range expansion.

The Spotted Lantern Fly (SLF), Lycorma delicatula (Hemiptera: Fulgoridae), is a sap feeding pest native to southeast Asia that has become a global biosecurity threat following invasions into South Korea, Japan, and the United States in the last two decades. Environmental niche modelling has demonstrated considerable potential for further range expansions, including into Australia and Europe. Further analysis on the potential seasonal life-history and survival of this pest in its invasive range can inform monitoring programs and is a next step in biosecurity preparedness. Here, we incorporated eco-physiological information on the development and survival of SLF life stages across temperature regimes. Using gridded climatic data, we then mapped the developmental sequence of SLF across ranges already occupied in China, South Korea, and the United States, as well as uninvaded ranges in Australia and Europe. The model was able to capture global observations of the seasonal appearance of SLF and highlight regional and seasonal vulnerabilities in regions at risk of invasion. Policy makers can use these results to make science-based biosecurity decisions and target preparedness activities through improved life-history predictions in its invasive range.
