Knotweeds are over 2m tall already in Michigan so we MSU Entomology have started the first knotweed psyllid releases of the season. These tiny critters have a mighty task. Happy feeding for them and hopefully not 'of them'. #NotMiSpecies


New year, new sets of Hypena adults and larvae are released against swallow-worts MSU Entomology. So far they are happy in the cages, laid eggs, and we started seeing first instar larvae. Let's hope they take well to this heat...#NotMISpecies

We are doing both open field and caged releases of psyllids for biocontrol of invasive knotweeds MSU Entomology. Started seeing the first signs of damage in the field as knotweed leaves curl as a result of psyllid feeding.


A new biocontrol book is out! Contributions of Classical Biological Control to the U.S. Food Security, Forestry, and Biodiversity. Van Driesche, R. G., R. L. Winston, T. M. Perring, and V. M. Lopez (eds.) The book is free as a high res PDF here: gcc02.safelinks.protection.outlook.com/?url=https%3A%…

Releases for biocontrol of swallow-worts are showing promise as we start seeing the second generation of moth larvae in the field. Grad student Brianna Foster also keeps busy in the lab MSU Entomology with a monster cage experiment. #NotMiSpecies



Check out our new paper on parasitoid evolution in response to the invasive #SpottedWingDrosophila led by the excellent Shelley Linder (not on Twitter), with Dr. Marianna Szucs @msuberrybugs @philipfanning in Evolutionary Applications PAPER: onlinelibrary.wiley.com/doi/epdf/10.11…

When infestations of #InvasiveSpecies become too large to control chemically & mechanically, what are the alternatives? Explore classical biological control as a tool to manage invasives w/Marianna Szucs MSU Entomology in our Jan. 18 #NotMiSpecies webinar. bit.ly/3Qu3pGh


We have prepared informative and beautiful factsheets of invasive swallow-worts and the biocontrol agent Hypena opulenta. Check them out: bugwoodcloud.org/resource/files… bugwoodcloud.org/resource/files… MSU Entomology #NotMiSpecies


Brianna Foster It's that time of year again! We are ramping up our rearing of the biological control agent for invasive Swallow-wort vines. Adult moths will be ready for release in Michigan in 1-2 wks! #biologicalcontrol #invasiveplants Dr. Marianna Szucs MSU Entomology


The biological control agent Hypena opulenta begins to pupate by making a characteristic S or J shape. Many times, it will silk itself around leaf material, or in this case, some paper towel! #weedbiocontrol #biologicalcontrol Dr. Marianna Szucs MSU Entomology


If your beautiful lilies are eaten by beautiful red beetles and their less than beautiful larvae you are not alone. The lily leaf beetle is a recent invader to Michigan. We are starting a biocontrol program MSU Entomology by moving successful parasitoids from New England to MI.


We have released more Hypena opulenta this season for Swallow-wort biocontrol! Included in those releases is a 42 cage study to understand how different genetically diverse populations of H. opulenta perform in the field. Dr. Marianna Szucs MSU Entomology MSU College of Natural Science

There's some native plants blooming in my restoration experiment! This is year three of an experiment to assess which methods of restoration are effective for Swallow-wort including biocontrol treatments. Dr. Marianna Szucs MSU Entomology MSU College of Natural Science



We just released 800 Hypena opulenta for biological control of invasive swallow-worts in Michigan. This is the largest and genetically most diverse release at a single site. Keeping our fingers crossed for good establishment. #NotMiSpecies MSU Entomology
