“…Additional research into alternative hosts has shown that species of grape (Vitis spp.) may serve as an substitute host in the absence of ailanthus (Pugh et al 2016). Thus, SLF is a potential threat to the over $134 million in annual grape and orchard production of Pennsylvania (PA Dept.…”

This resource update provides an overview of the forest resources in Pennsylvania based on inventories conducted by the USDA Forest Service, Forest Inventory and Analysis (FIA) program of the Northern Research Station. Estimates are based on field data collected using the FIA annualized sample design and are updated yearly. 1 Information about the national and regional FIA program is available online at http://fia.fs.fed.us. FIA began annual inventories in Pennsylvania in 2000. For the 2017 inventory, estimates of current resource attributes, such as area, volume, and biomass, are based on 4,520 (3,015 forested) plot samples collected from 2011 to 2017. Estimates of components of change, such as net growth, removals, and mortality, are based on 4,143 (2,666 forested) samples collected from 2006 to 2011 and revisited from 2011 to 2017. Estimates from earlier inventories are shown for comparison. See Bechtold and Patterson (2005), Gormanson et al. (2018), and Burrill et al. (2018) for definitions and technical details. A complete set of inventory tables is available at

Bright colours in distasteful prey warn off predators, but processes associated with ontogenetic acquisition of warning colours and distasteful compounds have been studied in only a few organisms. Here, we study spotted lanternflies (Lycorma delicatula; Fulgoridae) that change to red colouration when they narrow their host plant preferences to primarily the tree of heaven (Ailanthus altissima; Simaroubaceae), which is chemically defended by quassinoids. In experiments, we showed that birds taste-avoided lanternflies collected on Ailanthus but not those collected on the secondary hosts. Birds also taste-avoided seeds infused with ailanthone, the main quassinoid sequestered from Ailanthus by lanternflies as shown through mass spectrometry analyses. Hence, the narrowing of host preferences by lanternflies synchronizes the timing of change to red colour with the acquisition of quassinoid defenses. A schematic graphical population-level model of these processes is provided. This is the first report of quassinoid sequestration by insects and the first evidence that Simaroubaceae plants provide defensive chemicals to insects. This is the first report of a fulgoroid insect sequestering identified chemical defenses. The results highlight the importance of the pan-tropical taxon Fulgoridae for evolutionary biology of complex aposematic strategies and for understanding the links between timing of defense sequestration, timing of host plant preference shifts, and timing of colour change.

Spotted lanternfly predicted to establish in California by 2033 without preventative management

Models that are both spatially and temporally dynamic are needed to forecast where and when non-native pests and pathogens are likely to spread, to provide advance information for natural resource managers. The potential US range of the invasive spotted lanternfly (SLF, Lycorma delicatula) has been modeled, but until now, when it could reach the West Coast’s multi-billion-dollar fruit industry has been unknown. We used process-based modeling to forecast the spread of SLF assuming no treatments to control populations occur. We found that SLF has a low probability of first reaching the grape-producing counties of California by 2027 and a high probability by 2033. Our study demonstrates the importance of spatio-temporal modeling for predicting the spread of invasive species to serve as an early alert for growers and other decision makers to prepare for impending risks of SLF invasion. It also provides a baseline for comparing future control options.
