![]() ![]() The micro-biome is the bacteria located in the SLF gut. This may change as the population of SLF increases.Īnother area of current study that Dr Urban discusses is the micro-biome of the spotted lantern fly. Early results show that this wasp is infesting the SLF egg masses but not a high rate. in 2004 to combat the Gypsy Moth infestation. This type of parasitic wasp was first introduced into the U.S. One study has found a parasitic wasp that lays its eggs into the egg mass of the SLF. Since the SLF is an invasive species, there are few natural predators found here in Chester County. Biological control is using a natural predator or enemy of the species and employing that for control. Further study is needed to understand this method of communication.ĭr Urban discusses non-chemical treatment studies being controlled using biological control. This is referred to as substrate born communication. Leaf hoppers, including the spotted lanternfly, call to each other through the plant. The study showed that SLF is like other leaf hoppers in that it is not attracted by sex pheromones. Sex Pheromone trapping is extremely effective in another invasive insect, the stink bug. The testing is being conducted in Pennsylvania, where SLF pressure is high, and Virginia, where SLF pressure is low.Īnother aspect of attracting SLF is a study on whether SLF are attracted by sex pheromones. This method can be very useful in areas where the use of insecticides is not permitted or not desired. Scientists are trying to develop a lure and trapping system to physically attract and then capture the SLF. Some of the preventative and monitoring methods that Dr Urban discusses includes the use of lures and traps. Results of the studies have been limited to date but researchers have identified 10 new compounds that are now labeled to for SLF treatments. Maple trees are the common species of tree used in the study due to SLF having a preference for it. ![]() The other two studies are focusing on fruit trees and ornamental trees. Common examples of these objects include apple and grape cases. The focus of this study is test the effects of treating objects that have egg masses on them. One study is studying the effects of insecticides on the egg cases. There are 3 main insecticide studies happening on the SLF. Some of the treatment studies that Dr Urban describes includes the use of insecticides. Like the woolly adelgid, SLF feeds on longer lived trees which can cause longer term damage to the native species of tree. While many sap sucking insects, like the woolly adelgid, prefer one species of tree, the SLF feeds on many species of tree. The Spotted Lanternfly is unique among other sap suckers. ![]() In 2018, the SLF was designated as a “leaf hopper” which is a listed pest on many insecticides. Since SLF was not a listed pest on the label, we could not treat. This is because we can only use an insecticide to treat for insects that are listed on the label of the chemical. Prior to this order, pest control professionals were not legally able to treat for SLF. In the spring of 2018, the PA Department of Agriculture starting allowing the use of insecticides to treat for the SLF. Since the spotted lanternfly is an invasive species, the initial action was to institute a quarantine. Some of the international scientists came from China and Korea where the SLF originated. ![]() Initially, the PA Department of Agriculture assembled a group of scientists from all over the world to to study the SLF. As homeowners and pest control professionals, we have all had to learn how to protect our trees and treat this invasive species. It has been a little over 4 years since the introduction of the Spotted Lanternfly (SLF) in Berks County. If you would like to few the video, you can check it out here. Although the public is becoming more informed about this invasive species, the update provided by Dr Urban shows the hard work being done to combat this insect.ĭr Urban created a very informative video outlining the work and studies being performed. Dr Julie Urban from the Department of Entomology at Penn State, provided an update on the spotted lantern fly in September of 2018. The spotted lanternfly has become a huge problem for Chester County and surrounding areas since its introduction to the U.S. Spotted Lanternfly September 2018 Update Spotted Lanternfly Treatments ![]()
