<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1f497d">It is my understanding that control of spotted lanternfly does NOT use any sort of pheromone trap as Richard alludes to. I do not believe they have discovered
any sort of attractant. They are simply banding Ailanthus trees that have been found to be attractive to the insect as Marion points out below. Of course, homeowners can also choose to band other species. You can also read about the “trap” tree method of
control on our Extension page, link below.<u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1f497d">In addition, we have determined that stump treating Ailanthus is an ineffective mean of control. Cutting the tree removes the mechanism that moves the herbicide
to the roots, i.e. the phloem. In cases where the tree has to be cut it is much more effective to kill the tree first, wait 30 days and then cut the tree. See Art Gover’s Quick Sheet link below for Ailanthus control.<u></u><u></u></span></p>

techniques the PA Department of Agriculture may be using for the lanternfly, I'm only well familiarized with their tree banding efforts. These bands don't necessarily attract the lanternfly to the tree, but capture adults visiting Ailanthus to lay eggs, or
nymphs looking for a meal. Currently the state is only banding Ailanthus, no other potential host species. I'm gauging the interest of the PA A.T. maintaining clubs to see if volunteers would be interested in setting up some tree band monitoring areas. We
would very much like to have a better picture of where the lanterfly currently is along the A.T. and how it may be using the trail corridor to move. The Dept. of Ag. asks that the bands be visited and reported on at least every other week. <u></u><u></u></span></p>
<p><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black"><u></u> <u></u></span></p>
<p><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">I also can't speak to PA Game's strategy for treating Ailanthus, but basal bark, cut stump, and hack-and-squirt treatments can all be used to effectively kill Ailanthus. These methods
can be labor intensive, but are extremely precise, and greatly reduce any concern regarding non-target treatments. While foliar treatments may be the only feasible treatment option in dense stands, these more selective treatments can be used in lower density
areas and can alleviate many of the concerns that you mentioned. Following best management procedures <wbr>regarding equipment, droplet size, and weather conditions will also reduce non-target concerns. Still, non-foliar treatments are the preferred method used
for Ailanthus along the A.T. corridor. <u></u><u></u></span></p>

as a local commuting route. Blue Mountain and the Appalachian Trail are a few minutes north of us. There is at least one large fruit orchard nearby. We buy vegetables from a local organic grower.</span><span style="font-family:"Courier New""><u></u><u></u></span></p>

<span style="font-family:"Courier New";color:black"> This summer I will be spending a lot of time along the Appalachian Trail and other trails in Berks County, PA. My goals are twofold. The first is to continue research on <i>Castanea dentata</i> and its natural
comeback from the blight while taking down the severely misguided American Chestnut Foundation. The second will be observation of the spotted lanternfly to learn as much as I can as fast as I can. To this end I will be especially looking at <i>Celastrus orbiculatus</i>,
various <i>Lonicera sp.</i>, <i>Rosa multiflora</i>, other woody non-natives from Asia and naturally <i>Ailanthus altissima</i> to see if the spotted lanternfly feeds on these plants from its point of origin.</span><span style="font-family:"Courier New""><u></u><u></u></span></p>

<span style="font-family:"Courier New";color:black"> It would be a valuable research project if someone were to collect these plants along with native equivalents and test them directly with the spotted lanternfly to learn which ones are potential food sources.
For now, the local agriculture people are focusing on <i>Ailanthus</i>. However, if the Asian plants serve as preferential food sources over native plants we will have an overwhelming breeding area because in Berks County the understory is almost all non-native
in large areas of disturbed forest.</span><span style="font-family:"Courier New""><u></u><u></u></span></p>

<span style="font-family:"Courier New";color:black"> </span><span style="font-family:"Courier New""> A big concern of mine with the panic locally is that scared people act stupidly and scared stupid people act very stupidly. (Then there are the illiterate
politicians we have to deal with in Berks County and Pennsylvania who are feeding the panic.) My expectation is that many farmers will be loading up their fruit and vegetable crops with more pesticides than they already are. This makes me hesitant to buy local
produce unless it is labelled "organic". It will also add more poisons to our streams, land, ground water and the air we breathe. We are already inundated with agricultural poisons - how much more can we and the ecosystems take? Many of the local ecosystems
are already in a catastrophic state - I fear the additional damage.<u></u><u></u></span></p>

<span style="font-family:"Courier New";color:black"> My understanding of how <i>
Ailanthus</i> is killed by the PA Game Commission is that they spray the trees with glyphosate and/or triclopyr. If this is still the practice and is generalized with the PA Ag department, then the collateral damage will be huge as spray drift is hard to control
and perfect windless conditions are almost non-existent. I understand that to use other methods is impractical with the number of
<i>Ailanthus</i> trees in Berks and Schuylkill counties, especially with clonal stands. However, there must be a better method or at least more benign chemicals which do the same.</span><span style="font-family:"Courier New""><u></u><u></u></span></p>

<span style="font-family:"Courier New";color:black"> It appears that the PA Ag folks are falling into the Japanese beetle trap syndrome by setting up trap trees around fields of vulnerable crops. The result will be instead of keeping the spotted lanternfly
away from the crops, it will be bringing them into the fields instead. I have heard that the best place for a Japanese beetle trap is your neighbor's yard as it will attract them there instead of to your yard. This is good advice for keeping the spotted lanternfly
off crops.</span><span style="font-family:"Courier New""><u></u><u></u></span></p>

<span style="font-family:"Courier New";color:black"> Our organic garden was severely damaged by the Brown Marmorated Stinkbug last summer. The tomatoes which survived the localized tomato blight were full of bites from the BMSB. We lost about 90% of our late
season pole beans to the BMSB. Peppers were untouched as were other vegetables. If the spotted lanternfly has similar feeding habits to the BMSB our garden will be an unfortunately great place to observe how these two insects interact.</span><span style="font-family:"Courier New""><u></u><u></u></span></p>

<span style="font-family:"Courier New";color:black"> Finally, if the hatching of the spotted lanternfly eggs is in sync with the leafing out of <i>Ailanthus</i>, it is a strong indicator that <i>Ailanthus</i> is a requirement for successful development and
reproduction. Near home in the lower elevations, the non-native understory is in leaf. <i>Ailanthus</i> appears to still be in dormancy, even though the temperatures this weekend may change that. </span><span style="font-family:"Courier New""><u></u><u></u></span></p>
