Heterospecific Hymenoptera Found Inside The Nests Of Bombus Impatiens (Hymenoptera: Apidae)., Kelsey K. Graham
The Great Lakes Entomologist
The nests of social Hymenoptera are particularly attractive to species engaging in resource robbing due to their concentration of resources. Here, the identity of heterospecific intruders in Bombus impatiens nests are described, with a particular focus on intrusion by invasive species – Vespula germanica and Anthidium oblongatum. While V. germanica is well known as a resource robber, this is the first time Anthidium spp. have been documented entering the nest of a social heterospecific. Of 16 Bombus impatiens colonies placed in a field in Lansing, MI, eight had heterospecific intruders, including Apis mellifera, A. oblongatum, and V. …

Insect Visitors Of Cirsium Pitcheri, A Threatened And Endemic Dune Species, In Relation To Annual Weather Variation, Jordan M. Marshall
The Great Lakes Entomologist
Cirsium pitcheri (Torr. ex Eaton) Torr. & A. Gray (Pitcher’s thistle) is a threatened herbaceous plant endemic to sand dune ecosystems along Lakes Huron, Michigan, and Superior in North America. Habitat for this plant is limited to active dunes with moving sand. I observed floral visitors of C. pitcheri in Indiana Dunes National Lakeshore and Indiana Dunes State Park, and calculated frequency and density of visitor families. Additionally, I tested for relationships between visitor counts and previous growing season mean temperature and precipitation. Formicidae, Anthomyiidae, and Cecidomyiidae were the most frequent families. However, Apidae was the only family correlated with …

Transmission Efficiency, Preference And Behavior Of Bemisia Tabaci Meam1 And Med Under The Influence Of Tomato Chlorosis Virus, Xiaobin Shi, Xin Tang, Xing Zhang, Deyong Zhang, Fan Li, Fei Yan, Youjun Zhang, Xuguo Zhou, Yong Liu
Entomology Faculty Publications
Tomato chlorosis virus (ToCV, genus Crinivirus, family Closteroviridae) is an economically important virus in more than 20 countries. In China, ToCV was first detected in 2013 and has already spread throughout the country. ToCV is transmitted in a semi-persistent manner by the whitefly, Bemisia tabaci, but not seed. In the past two decades, the most invasive MEAM1 and MED have replaced the indigenous B. tabaci in China, and currently MED is the most dominant cryptic species. To better understand the prevalence of ToCV with their vectors, we tested the hypothesis that the rapid spread of ToCV in …

Determining Bioindicators For Coastal Tidal Marsh Health Using The Food Web Of Larvae Of The Greenhead Horse Fly (Tabanus Nigrovittatus), Devika Rajeev Bhalerao
LSU Master's Theses
The greenhead horse fly Tabanus nigrovittatus Macquart is native to coastal marshlands from Texas to Nova Scotia. The larvae are apex invertebrate predators and their development is dependent on the food web in the soil. Surveillance of T. nigrovittatus after the 2010 Deepwater Horizon oil spill in the Gulf of Mexico showed population crashes of adults in the coastal marshes of East Louisiana near places where oil made landfall, but not in West Louisiana where the oil did not reach. Sediment collection in 2011 from West and East Louisiana revealed larval population crashes in the Eastern coastal region. We hypothesized …

A Method For Making Customized, Thick Labels For Microscope Slides., David J. Voegtlin
The Great Lakes Entomologist
This paper describes a technique for creating customized, thick (= 1 mm) slide labels, and fastening them permanently to slides so they can be stored vertically by stacking or horizontally like cards in a file without putting pressure on the coverslip. After 20 years, thick labels created by this technique have shown no sign of degradation; labels fastened to slides with silicone caulking have remained securely attached. A storage system, using insect drawer sized trays that hold large numbers of thick labelled slides, is shown. The use of thick labels and such a storage system simplifies the curation of large …

Habitat Characterization Of Five Rare Insects In Michigan (Lepidoptera: Hesperiidae, Riodinidae, Satyridae; Homoptera: Cercopidae), Keith S. Summerville, Christopher A. Clampitt
The Great Lakes Entomologist
Over 80 species of insects are listed as endangered, threatened, or special concern under Michigan's endangered species act. For the majority of these species, detailed habitat information is scant or difficult to interpret. We describe the habitat of five insect species that are considered rare in Michigan: Lepyronia angulifera (Cercopidae), Prosapia ignipectus (Cercopidae), Oarisma poweshiek (Hesperiidae), Calephelis mutica (Riodinidae), and Neonympha mitchellii mitchellii (Satyridae). Populations of each species were only found within a fraction of the plant communities deemed suitable based upon previous literature. Furthermore, individuals of each species were observed to be closely affiliated with just a few vegetation …

Sex Ratio And Sexual Dimorphism In Formica Exsectoides, The Allegheny Mound Ant (Hymenoptera: Formicidae), H. C. Rowe, C. M. Bristow
The Great Lakes Entomologist
We excavated 66 mounds from 6 populations of Formica exsectoides in Michigan jack pine, collecting sexual caste pupae for sex ratio estimates and measurement of dimorphism. Reproductive caste brood was present in only 37 ofthe 66 mounds, and presence of reproductive caste brood was associated with larger mound surface area. Females were heavier than males, but did not differ from males in energy density. Sexes did not differ in timing or rate of development. Sex ratio estimates based on individual mounds ranged from 1.0 (all male) to 0.08 (female·biased). Four of the six study populations were strongly male·biased, while sex …

Distribution Of An Exotic Pest, Agromyza Frontella (Diptera: Agromyzidae), In Manitoba, Canada., J. G. Lundgren, R. C. Venette, J. Gavloski, W. D. Hutchison, G. E. Heimpel
The Great Lakes Entomologist
Agromyza frontella is an exotic alfalfa pest from Europe that was first detected in North America in 1968 and has since spread westward into Ontario and the north central United States. Informal surveys had detected A. frontella in Manitoba, but its distribution throughout this province was unknown. In 1998 we collected alfalfa stems to detect plant damage and sweep samples to detect adult A. frontella and the parasitoid Dacnusa dryas throughout the alfalfa growing region of Manitoba. In south central Manitoba, 100% of stems were damaged by A. frontella, and> 100 adults/10 sweeps were recorded at several sites. In …

The Aphids (Homoptera: Aphididae) Associated With Bell Peppers And Surrounding Vegetation In Southern Illinois, Godfrey H. Kagezi, David J. Voegtlin, Richard A. Weinzierl
The Great Lakes Entomologist
Outbreaks of cucumber mosaic virus (CMV) disease, caused by an aphid- transmitted pathogen, greatly reduced yields of bell pepper in southern Illinois in the mid-1990s. To provide the basis for further studies of the roles of individual apbid species in virus transmission, we surveyed aphid flights in and around pepper fields in 1996 and 1997 by using suction traps, interception nets, landing traps, sweep nets, and hand-picking. We collected 78 species of aphids, 15 of which have been reported to transmit CMV to peppers. The most abundant species taken from suction traps and interception nets in combination were Lipaphis erysimi, …
