Seasonal Occurrence Of The Sod Webworm Moths (Lepidoptera: Crambidae) Of Ohio, Harry D. Niemczyk, David J. Shetlar, Kevin T. Power, Douglas S. Richmond Jan 2018

Seasonal Occurrence Of The Sod Webworm Moths (Lepidoptera: Crambidae) Of Ohio, Harry D. Niemczyk, David J. Shetlar, Kevin T. Power, Douglas S. Richmond

The Great Lakes Entomologist

While nearly 100 species of sod webworms are known to occur in North America, the species complex and seasonal occurrence of these moths has been documented in relatively few states. For Ohio, there is little published record of the sod webworm species complex, and the seasonal occurrence of only a few economically important species has been documented. Using black light traps, sod web worm adult flight activity was monitored over the course of three to five years at four different locations throughout Ohio. In this paper we report the seasonal occurrence of sod web worms species captured at these locations. …

New Michigan Tick (Acari: Ixodidae) And Flea (Siphonaptera: Ceratophyllidae) Records From Colonial Nesting Birds, William C. Scharf Jan 2018

New Michigan Tick (Acari: Ixodidae) And Flea (Siphonaptera: Ceratophyllidae) Records From Colonial Nesting Birds, William C. Scharf

The Great Lakes Entomologist

Banding and censusing large numbers of gull chicks over a 30-year period on Great Lakes islands has produced a collection of five individual ticks from two Herring Gull (Larus argentatus) chicks. The tick species, Hemaphysalis leporispalustris, found on the gulls is commonly found on Snowshoe Hares (Lepus americanus). Although this represents an apparently uncom­mon record on Herring Gulls, this host could be an important source of aerial vector dispersal during regular cyclic hare/tick population peaks. Populations of the flea, Ceratophyllus lari, have increased rapidly in ground nesting Double-crested Cormorant (Phalacrocorax auritus) colonies from none 16 years ago. The …

Color, Bacteria, And Mosquito Eggs As Ovipositional Attractants For Aedes Aegypti And Aedes Albopictus (Diptera: Culicidae), Steven G. Pavlovich, C. Lee Rockett Jan 2018

Color, Bacteria, And Mosquito Eggs As Ovipositional Attractants For Aedes Aegypti And Aedes Albopictus (Diptera: Culicidae), Steven G. Pavlovich, C. Lee Rockett

The Great Lakes Entomologist

Selected bacterial washes, color, and mosquito eggs were comparatively examined as ovipositional attractants for Aedes aegypti and Aedes albopictus. Any evidence of additive activity was noted. All colored washes alone were preferred over selected bacterial washes. The combinations of color and bacteria in a single wash were better attractants for oviposition than colored washes alone. The bacterial content of the breeding water was a more important factor than egg presence in oviposition site selection.

Life History Of Ceratocombus Vagans (Hemiptera: Heteroptera: Ceratocombidae), With Notes On The Immature Stages, John D. Lattin Jan 2018

Life History Of Ceratocombus Vagans (Hemiptera: Heteroptera: Ceratocombidae), With Notes On The Immature Stages, John D. Lattin

The Great Lakes Entomologist

The biology and life stages of Ceratocombus vagans are given together with distributional notes. The current systematic position of Ceratocombidae is reviewed. This species is one of the most generalized Hemiptera: Heteroptera known. Its predatory habits lend credance to the idea that primitive Hemiptera: Heteroptera were predaceous as suggested by Stys and others. Ceratocombus vagans occurs in moss, leaf litter, and under loose bark. It has wide distribution in much of North America.

Sperm Depletion And Mating Behavior In The Parasitoid Wasp Spalangia Cameroni (Hymenoptera: Pteromalidae), Bethia H. King Jan 2018

Sperm Depletion And Mating Behavior In The Parasitoid Wasp Spalangia Cameroni (Hymenoptera: Pteromalidae), Bethia H. King

The Great Lakes Entomologist

Mating behavior was examined in the parasitoid wasp Spalangia cameroni. Males attempted copulation with both virgins and already mated females. Males attempted copulation regardless of whether they still had sperm. Already mated females rejected attempts to mate again but virgin females would mate 'with males regardless of whether or not they had sperm left. Males mated with 12-52 females before exhausting their sperm sup- plies. Males that had mated only once daily exhausted their sperm supplies in their late thirties (days old), if ever; and males that had mated four times daily exhausted their's at 7-13 days. Males produced …

Dispersal And Re-Capture Of Marked, Overwintering Tomicus Piniperda (Coleoptera: Scolytidae) From Scotch Pine Bolts, A. V. Barak, D. Mcgrevy, G. Tokaya Jan 2018

Dispersal And Re-Capture Of Marked, Overwintering Tomicus Piniperda (Coleoptera: Scolytidae) From Scotch Pine Bolts, A. V. Barak, D. Mcgrevy, G. Tokaya

The Great Lakes Entomologist

The pine shoot beetle (PSB), Tomicus piniperda is a recently established exotic pest of live pine in the southern Great Lakes of the U.S. and Canada. Scotch pine, Pinus sylvestris L. is the most susceptible pine species, but the adult also attacks several other North American species of Pinus. This research investigated the dispersal behavior of beetles emerging from overwintering sites to aid in the development of effective monitoring and management practices. Scotch pine logs with overwintering PSB were sprayed with fluorescent pigments to mark dispersing beetles. These logs were placed in piles in the centers of three circular …

Seasonal Shoot-Feeding By Tomicus Piniperda (Coleoptera: Scolytidae) In Michigan, Robert A. Haack, Robert K. Lawrence, George C. Heaton

The Great Lakes Entomologist

Seasonal shoot-feeding by Tomicus piniperda (L.) was monitored at 2­ week intervals on 15 Scotch pine, Pinus sylvestris L., trees from 8 April through 16 November 1994 in southern Michigan. All shoots that showed evidence of T. piniperda attack were removed every two weeks. In 1994, initial spring flight of T. piniperda began on 22 March. At least two live T. piniperda adults were found on the 15 trees on each sampling date from 8 April through 1 November 1994. In addition, at least one freshly attacked, beetle- free shoot was found on each sampling date except for 1 November. …

Wheat Stem Maggot In Spring Wheat-Alfalfa Intercrops With Different Crop Management Intensities, Louis S. Hesler, Robert W. Kieckhefer Jan 2018

Wheat Stem Maggot In Spring Wheat-Alfalfa Intercrops With Different Crop Management Intensities, Louis S. Hesler, Robert W. Kieckhefer

The Great Lakes Entomologist

Larval infestations and adult counts of wheat stem maggot (Meormyza americana) were each compared among plots of intercropped spring wheat and alfalfa grown under high, intermediate, or low crop management intensity (CMI). CMI varied primarily in the amounts of nitrogen fertilizer, herbicide, and tillage used. Infestation of wheat plants was measured from 1990 through 1993 as the percentage of white grain heads caused by larval feeding within the stems. Adult counts were made from sweep net samples within plots 3 to 5 times per year from 1991 through 1993. Larval infestation varied among years but not by CMI. The mean …

The Great Lakes Entomologist

Natural infestations of cereal aphids and abundance of their predators were compared from 1990 through 1993 among plots of intercropped spring wheat and alfalfa grown under high, intermediate, or low crop management intensity (CMI). CMI treatments differed in the amount of nitrogen fertilizer applied and herbicide used and in the rigor of tillage operations. Cereal aphids (primarily Rhopalosiphum padi, Sitobion avenae, and Schizaphis graminum) collectively infested a mean of 0 to 5.9 of 15 wheat tillers sam­pled per plot on various dates from 1990 through 1993, but aphid infestation did not vary by CM!. Seven taxa of aphid …

Tomicus Piniperda (Coleoptera: Scolytidae): Is Shoot Feeding Required For Reproductive Maturation?, Therese M. Poland, Robert A. Haack Jan 2018

Tomicus Piniperda (Coleoptera: Scolytidae): Is Shoot Feeding Required For Reproductive Maturation?, Therese M. Poland, Robert A. Haack

The Great Lakes Entomologist

The pine shoot beetle, Tomicus piniperda (Coleoptera: Scolytidae), is a univoltine pest of pine in its native range of Europe and Asia. Tomicus piniperda is now widely established in the Great Lakes region and poses a potentially significant threat to other pine-producing areas in North America. An unusual aspect of the life history of T. piniperda is the extended period of maturation-feeding that takes place in the shoots of living pine trees and subsequent overwintering before adults reproduce the following year. We investigated the extent to which shoot-feeding is required by newly-emerged T. piniperda before introduction into Scotch pine (Pinus …

Heterospecific Hymenoptera Found Inside The Nests Of Bombus Impatiens (Hymenoptera: Apidae)., Kelsey K. Graham Jan 2018

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 Jan 2018

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 Jan 2018

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 Jan 2018

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 …
