ALB look-alikes guide, 8.5×11 inches
The Massachusetts Department of Agricultural resources (MDAR) has new items in stock that you can order, free of charge, to help raise awareness about the invasive Asian Longhorned Beetle (ALB). Two of our most popular handouts, our ALB look-alike sheet and our ALB tree guide, are now available in single-sided laminated form, perfect for display outside or indoors. You can use them to educate campers, tenants, office workers and visitors, park goers, or any passersby about how to identify this invasive pest and the trees it attacks. Community involvement and awareness is a key part of the effort to eradicate ALB. The more people know about the beetle, the better equipped they will be to stop it from spreading.

Just a reminder: Here in Massachusetts, the bugs may be flying, but Asian Longhorned Beetle won’t emerge from the trees until July. If you’re seeing big black beetles with long, long antennae in May and early June, they are almost certainly the native look-alikes knows as Whitespotted Pine Sawyers.

With Arbor Day only a month away, it’s time to think about planning how we can celebrate trees and their ability to provide our neighborhoods with clean air, shaded streets, and aesthetic value. This year, why not consider joining our Arbor Day ash tree tagging project! Spearheaded by the Mass. Department of Agricultural Resources (MDAR), the goal of this project is to get as many organizations as possible to tag at least one ash tree to spread the word about Emerald Ash Borer (EAB).
EAB is an invasive tree-killing beetle from Asia that feeds on ash trees (Fraxinus spp.), a common component of our urban forests and rural woodlands. First detected in Massachusetts in 2012, established EAB infestations have now been confirmed in more than ten communities across four counties in our state (Berkshire, Essex, Suffolk, and Worcester). Infested ash trees die in 3-5 years, in many cases becoming hazards to people and property as dead trees decay and fall apart.
If you have ash trees in your town and want to help raise awareness about the impact of Emerald Ash Borer this Arbor Day (April 29th), MDAR is offering free Tree Tagging Kits to interested groups. The kits come with tags printed on high-visibility green plastic board, flagging tape to tie them onto trees, and a tip sheet to get the most out of your tagging efforts. Through raising awareness of the impact of Emerald Ash Borer, we hope to foster early detection of this pest, something that will provide communities with the time needed to prepare for the EAB’s arrival and make important decisions about how to manage their ash trees.

Spring is in the air! With these mild temperatures, tree buds are beginning to swell and soon the winter moths we witnessed swarming at our porch lights over winter will start hatching into hungry, green caterpillars. The winter moth (Operophtera brumata) is an invasive species first discovered in Massachusetts in the 1990s. Winter moth caterpillars are highly efficient tree defoliators, often stripping the leaves of oaks, maples and other hardwood trees down to lacy skeletons.
Between November 2015 and January 2016 over 2200 people took the time to respond to our survey after being “bugged” by swarms of winter moth. Here are some of the results:

Of the 2200+ responses received in our survey the counties with the highest number of participants were:
However, the individual towns with the most respondents were:
While we’ve been slowly watching the winter moth expand its range westward in Massachusetts, we only saw a small uptick in survey participation in Worcester County.
It’s important to note that high turn-out for a town or county is not at all indicative of increased winter moth activity in those areas, rather just that these folks are probably more active on social media and sharing of the survey among local groups was more popular!
The majority of people responding to the survey indicated that the winter moths were most commonly seen at the porch lights on their homes, and over half of respondents reported seeing 50+ winter moths at a time (i.e. LOTS)!
As in previous years, the information collected through this survey is shared with scientists over at the University of Massachusetts where they are working on a biological control program to combat the winter moth.
The results are in… Massachusetts Wasp Watchers had a record season in 2015!
The smoky-winged beetle bandit (Cerceris fumipennis) is a native, non-stinging wasp species that feeds its young by catching Buprestid beetles, including the most infamous: emerald ash borer (Agrilus planipennis). Cerceris wasps are an important early detection tool that can assist in slowing the spread of emerald ash borer (EAB) and alerting us to potential infestations in new counties and towns in Massachusetts.
With EAB detections now in four Massachusetts counties (Berkshire 2012, Essex 2013, Suffolk 2014, Worcester 2015), volunteers and staff did a great job ramping up their Wasp Watcher efforts. This November, EAB was found by crews surveying for the invasive Asian Longhorned Beetle in the city of Worcester. (EAB Found in Worcester)

Sixteen people participated in this year’s Wasp Watchers program by visiting established Cerceris colonies, monitoring the wasp nests and collecting discarded buprestid beetles. The 2015 Massachusetts Wasp Watchers achieved the following:
- Checked 141 sites throughout Essex, Barnstable, Middlesex, Norfolk, Suffolk, Plymouth and Worcester counties.
- Completed 282 site visits in total.
- Collected beetles at 42 locations in 30 different towns.
- Together, we collected a total of 648 Buprestid beetles
- Of the 648 Buprestid beetles that were picked up, 256 were Agrilus species. Agrilus is the buprestid genus we care the most about, because there are several non-native Agrilus species of interest, including EAB. However, NONE of our Agrilus were EAB or any other target pests.
Thank you to all who participated in this year’s survey!
In early January, the Mass. Dept. of Agricultural Resources (MDAR) partnered with the Massachusetts Forest Pest Task Force to hold an Emerald Ash Borer (EAB) Preparedness Forum at Tower Hill Botanic Garden in Boylston, MA. The event had a great turnout, with over 65 participants from more than 30 communities across Massachusetts in attendance. This day-long forum provided attendees with an update on the current status of EAB in our state as well as information about what should be done to prepare for this pest and how to get the resources to do so. More importantly, participants, who were representatives from communities impacted or soon-to-be impacted by EAB, gathered together with experts, including representatives from MDAR, MA Dept. of Conservation and Recreation, US Forest Service, USDA, Cornell University, UMass Amherst, and National Grid, to discuss new ideas about how communities in Massachusetts can best prepare for and respond to EAB.
Nathan Siegert, US Forest Service, provides participants an overview of EAB.
Resources lined the tables upon participant’s arrival to the forum.
If you were unable to attend the forum or would simply like to check out all of the great resources provided that day, we have now made them available online! Detailed notes covering all of the day’s sessions, PowerPoints for each of the presentations, and digital versions of the resources provided are now accessible at the following link: http://bit.ly/1KD8ebS
As you may have read in the news last week, state officials from the Department of Conservation and Recreation (DCR) recently confirmed the presence of Emerald Ash Borer (Agrilus planipennis, “EAB”) in the city of Worcester, MA. EAB is a small, metallic green beetle, native to Asia, which feeds on ash trees (Fraxinus spp.) and white fringe tree (Chionanthus virginicus). This pest can kill a tree quickly, within just 3 to 5 years, because it bores directly under the bark and disrupts the tree’s conductive system. It has now spread throughout 25 states, killing millions of ash trees and causing billions of dollars in treatment, removal and replacement costs.
In late November, four infested trees were found by crews in Worcester that were checking trees for another invasive pest, the Asian Longhorned Beetle. With EAB already in Berkshire and Essex Counties, the arrival of this pest in the central part of Massachusetts is not unexpected. But while the confirmation of EAB in Worcester is not cause for alarm, it is an invasive pest and it does require communities to alter the way they are managing forests and street trees in order to deal with the pending loss of ash.
Although eradication of EAB is not feasible, slowing its spread allows communities to prepare in advance and make the best decisions about how to manage ash trees before they are impacted. To prevent the inadvertent spread of forest pests like EAB, avoid moving untreated firewood long distances. Instead, find local and trusted firewood suppliers, or purchase firewood that is certified as treated.
With this new find in Worcester, MA, it is important to recognize that although the statewide emerald ash borer quarantine allows ash and firewood to be moved throughout the state, ash remains a host for Asian Longhorned Beetle. Therefore no ash products or firewood can be moved from within the 110 square mile regulated area encompassing Worcester, Boylston, West Boylston, Shrewsbury, and parts of Holden and Auburn.
The Chief Apiary Inspector at the Mass. Dept. of Agricultural Resources (MDAR), Kim Skyrm, sent us this note about a survey her team is sending out to beekeepers, to gather information about hive health. If you are a Massachusetts beekeeper (or know someone who is), read below:
MDAR has created a survey to serve as a tool for Massachusetts honey beekeepers to share data on any hive losses that may have occurred during the 2015 season. Participation in this survey is voluntary. Responses will be analyzed by MDAR Apiary Program staff, who will then provide a summary of results to the beekeeping community this winter.
Beekeepers can take the survey by clicking here. In addition, beekeepers willing to submit photos documenting any 2015 hive health issues can send them via email. Photos will be reviewed and responses provided in a timely manner. If you have specific questions that you want addressed, please include that information in the email.
Thank you for taking the time to complete this survey and provide feedback on the health of your hives.
It’s that time of year again: winter moths and other related species have started to show up at porch lights across the state. The winter moth (Operophtera brumata) is an invasive species first discovered in Massachusetts in the 1990s. Winter moth caterpillars are highly efficient tree defoliators, often stripping the leaves of oaks, maples and other hardwood trees down to lacy skeletons.
In mid-to-late fall, at a time of year where insect activity is practically at a standstill, these small brown winter moths will be seen across the eastern half of the state, sometimes congregating at porch lights by the hundreds. There are other similar-looking native moths active at this time of year, such as the Bruce spanworm moth and the fall cankerworm moth, but they are typically not seen in such large numbers. While the state does not regulate winter moth, some towns/cities do tree treatments, and the Elkinton Lab at University of Massachusetts Amherst currently has a biological control program underway.
The survey for 2015 is now closed. Thank you for your participation. The information you share will help assess the distribution of this invasive pest in our state.
