Sirex Nigricornis (Hymenoptera: Siricidae) Larval Development Correlated With Tree Characteristics And Ophiostomoid Fungal Infection, Jess Hartshorn, Larry D. Galligan, Fred Stephen Feb 2021

Sirex Nigricornis (Hymenoptera: Siricidae) Larval Development Correlated With Tree Characteristics And Ophiostomoid Fungal Infection, Jess Hartshorn, Larry D. Galligan, Fred Stephen

The Great Lakes Entomologist

The native North American wood wasp, Sirex nigricornis F., has received significant attention over the last several years due to the introduction and successful establishment of the European wood wasp, S. noctilio L. in eastern North America. Larval size and development of S. nigricornis are important variables that can help to compare demography of the two species and predict future interactions. We measured head capsule width, body length, and weight of S. nigricornis larvae removed from 14 pine trees, felled across the Ozark and Ouachita National Forests of Arkansas in 2012. We also recorded the height at which larvae were …


The Probability Of Spotted Lanternfly, Lycorma Delicatula (Hemiptera: Fulgoridae), Escape Differs Among Life Stages And Between Two Trapping Techniques Commonly Used By Landowners, Sticky Bands And Duct Tape., Matthew Desko, Carolyne Schiebel, Samantha Silverman, Jessica Bickel, Karen Felton, Jennifer L. Chandler Feb 2021

The Probability Of Spotted Lanternfly, Lycorma Delicatula (Hemiptera: Fulgoridae), Escape Differs Among Life Stages And Between Two Trapping Techniques Commonly Used By Landowners, Sticky Bands And Duct Tape., Matthew Desko, Carolyne Schiebel, Samantha Silverman, Jessica Bickel, Karen Felton, Jennifer L. Chandler

The Great Lakes Entomologist

The invasive Lycorma delicatula (White) was first identified in Pennsylvania, U.S.A. in 2014, and has since increased its range to several Eastern states. Lycorma delicatula pose a serious threat to many native species, including hardwoods and grapes, and land owners are continually seeking effective traps to control populations. Both commercially-produced Web-Cote brand sticky bands and less expensive duct tape are often used by land owners to trap L. delicatula. However, the probability of escape from these adhesives has not been formally assessed, and almost certainly differs as a function of life stage and type of adhesive used. The purpose …


First Records Of Megachile Apicalis (Hymenoptera: Megachilidae) For Illinois Found In Heavily Urbanized Areas Within The City Of Chicago, Andrea M. Gruver, Paul J. Caradonna Sep 2020

First Records Of Megachile Apicalis (Hymenoptera: Megachilidae) For Illinois Found In Heavily Urbanized Areas Within The City Of Chicago, Andrea M. Gruver, Paul J. Caradonna

The Great Lakes Entomologist

We provide the first record of the non-native Megachile apicalis Spinola (Hymenoptera: Megachilidae) in Illinois. Thirty Megachile apicalis specimens were collected in the summer of 2018 in a highly urban area of Chicago, IL, USA. Our findings suggest that the range of Megachile apicalis appears to be rapidly expanding across North America, inward from both the East and Western Coasts. Megachile apicalis in Chicago has a broad activity period, can take advantage of abundant non-native floral food resources, and has competitive nesting behavior, all of which may facilitate its successful establishment in disturbed urban environments, as well as its continued …


First Records Of The Adventive Pseudoanthidium Nanum (Mocsáry) (Hymenoptera: Megachilidae) In Illinois And Minnesota, With Notes On Its Identification And Taxonomy, Zachary M. Portman, Skyler J. Burrows, Terry Griswold, Mike Arduser, Aaron J. Irber, Rebecca K. Tonietto, Daniel P. Cariveau Sep 2019

First Records Of The Adventive Pseudoanthidium Nanum (Mocsáry) (Hymenoptera: Megachilidae) In Illinois And Minnesota, With Notes On Its Identification And Taxonomy, Zachary M. Portman, Skyler J. Burrows, Terry Griswold, Mike Arduser, Aaron J. Irber, Rebecca K. Tonietto, Daniel P. Cariveau

The Great Lakes Entomologist

We report the first records of Pseudoanthidium nanum (Mocsáry) in Illinois and Minnesota in 2016 and 2018, respectively. This represents a relatively rapid expansion since P. nanum was first detected in New Jersey in 2008. In order to help monitor the spread of this bee, we provide information on how to identify P. nanum and provide images of the general habitus, diagnostic features, and male genitalia. Finally, we confirm the taxonomic identity of P. nanum in the United States and highlight potential impacts on native anthidiines.


Pentatomidae (Hemiptera: Heteroptera: Pentatomidae) Captured On Purple Prism Traps Deployed For Detection Of Emerald Ash Borer (Agrilus Planipennis) (Coleoptera: Buprestidae) In Minnesota, Daniela T. Pezzini, Mitch Haag, James Walker, Robert L. Koch Aug 2018

Pentatomidae (Hemiptera: Heteroptera: Pentatomidae) Captured On Purple Prism Traps Deployed For Detection Of Emerald Ash Borer (Agrilus Planipennis) (Coleoptera: Buprestidae) In Minnesota, Daniela T. Pezzini, Mitch Haag, James Walker, Robert L. Koch

The Great Lakes Entomologist

The observation of bycatch from insect trapping programs, though often considered bothersome, may hold value for ecological and taxonomic studies. In Minnesota, a large trapping survey consisting of pheromone-baited purple prism traps, has been conducted for early detection of Agrilus planipennis, the emerald ash borer. Stink bugs (Heteroptera: Pentatomidae), which are pests of increasing importance in the North Central U.S., were observed to be captured by these traps. The objective of this study was to use trap bycatch from the A. planipennis traps for further documentation of the abundance and diversity of Pentatomidae in Minnesota. In 2011 and 2012, 4,401 …
