As a result of the introduction of Sirex noctilio F. into North America, there has been increased interest in the poorly-described native Siricidae communities. To date, few studies have surveyed specifically for Siricidae, and many reports of native siricid populations are byproducts of sampling efforts targeting Coleoptera. We report results from a survey targeted specifically at native and exotic Siricidae in Minnesota. We used Lindgren funnel traps from 2006 to 2008 baited with α /β-pinene (Sirex lure), ethanol (EtOH), EtOH + α-pinene, or Ips 3-part lures. We captured 704 native Siricidae comprising seven species, of which none were exotic. To our knowledge, this is one of the largest field collections of Siricidae from a single discrete set of localities in existence. Adult Siricidae began flying in June and continued into October each year. The α/β-pinene lure was most effective, but the EtOH + α-pinene lure was also moderately effective. We compare our data with those from several states and provinces in the Great Lakes Region of North America. Our data provide insight into the community composition of native Siricidae in Minnesota, while concurrently providing evidence that S. noctilio populations have not yet reached this far into the continental United States. © 2012 Entomological Society of America.

Stink bugs (Hemiptera: Heteroptera: Pentatomidae) that occur in Minnesota wheat have received little attention. Due to the invasion of Halyomorpha halys (Stål) and the increasing abundance of native stink bugs in the region, a 2-yr statewide survey and 2-yr season-long survey were conducted to characterize the species composition, abundance, and seasonal dynamics of Pentatomidae in wheat. Surveys were performed using sweep-net sampling in wheat fields. Fourteen species of Pentatomidae (thirteen herbivorous and one predatory) were detected across both surveys. The recent invader, H. halys, was not collected in either survey. In the statewide survey, Euschistus variolarius (Palisot de Beauvois) was the most abundant species (63.08 and 75.33% of adults in 2011 and 2012, respectively) and the most prevalent species (collected from 10.53 and 51.54% of fields in 2011 and 2012, respectively). Species of intermediate abundance and prevalence were Euschistus servus euschistoides (Vollenhoven), Euschistus ictericus (L.), and Podisus maculiventris (Say). Across both years of the season-long survey, adults of herbivorous species first appeared in fields in early June followed by the appearance of herbivorous nymphs in early July. The abundance of nymphs peaked in late July to the beginning of August in 2013 and in early July in 2014. Adults were detected in fields throughout the season. The results presented here provide baseline information on the species composition, abundance, and seasonal dynamics of Pentatomidae in Minnesota wheat and will be necessary for documentation of changes to this fauna. © 2016 The Authors.

Ticks and Tick-borne Diseases | Year: 2016

Large commercial laboratories in the United States were surveyed regarding the number of specimens tested for eight tickborne diseases in 2008. Seven large commercial laboratories reported testing a total of 2,927,881 specimens nationally (including Lyme disease). Of these, 495,585 specimens (17%) were tested for tickborne diseases other than Lyme disease. In addition to large commercial laboratories, another 1051 smaller commercial, hospital, and government laboratories in four states (CT, MD, MN, and NY) were surveyed regarding tickborne disease testing frequency, practices, and results. Ninety-two of these reported testing a total of 10,091 specimens for four tickborne diseases other than Lyme disease. We estimate the cost of laboratory diagnostic testing for non-Lyme disease tickborne diseases in 2008 to be $9.6 million. These data provide a baseline to evaluate trends in tickborne disease test utilization and insight into the burden of these diseases. © 2015 Elsevier GmbH. Source
