A Preservative-Free Emergent Trap For The Isotopic And Elemental Analysis Of Emergent Insects From A Wetland System, Richard A. Mackenzie, Jerry L. Kaster

The Great Lakes Entomologist

This study reports a cost-effective, live emergent trap designed for the preservative-free use in both biogeochemical and ecological analyses of emerging insects. The trap proved to be advantageous in several ways. First, the simple design made the trap time-efficient since it was easy to set-up, change, and maintain. Second, live sampling not only provided uncontaminated organisms for elemental and stable isotopic analyses, it minimized disfigurement. This resulted in rapid and easy handling, as well as identification, of adult insects. Finally, trap avoidance by ephemeropterans and odonates, a common problem encountered in the literature, was minimal and organisms from both insect …

Attraction Of Apple Maggot Flies (Diptera: Tephritidae) To Synthetic Fruit Volatile Compounds And Food Attractants In Michigan Apple Orchards, Lukasz L. Stenliski, Ocar E. Liburd

The Great Lakes Entomologist

The apple maggot, Rhagoletis pomonella (Walsh), is a serious pest of apples in the United States, requiring reliable monitoring and control programs. Various synthetic apple volatile lures with and without protein hydrolysate, ammonium acetate, or ammonium carbonate were evaluated from 1998-2000 for their attractiveness to R. pomonella adults with red sticky-sphere (9 cm diam.) monitoring traps. A blend consisting of butyl butanoate (10%), propyl hexano- ate (4%), butyl hexanoate (37%), hexyl butanoate (44%), and pentyl hexanoate (5%) was the most effective lure tested for attracting both sexes of R. pomonella adults during all three field seasons. The addition of protein …

Longitarsus Melanurus (Coleoptera: Chrysomelidae) Reproduces On Onosmodium Molle (Boraginaceae), Andrew H. Williams

The Great Lakes Entomologist

(excerpt)

Longitarsus melanurus (Melsheimer) was first associated with Onosmodium Michx. by Popenoe (1877) in Kansas where the sole species is O. molle Michx. (Great Plains Flora Assn. 1986). Recent field observations over several years showed that adults of L. melanurus feed on leaves of O. molle in Wisconsin, where these beetles were collected at 43 of the 59 sites where O. molle was found growing naturally (Williams 1996).

First Record Of Rhipiceridae (Coleoptera: Polyphaga: Dascilloidea) From Wisconsin, Daniel K. Young, Kerry Katovich

The Great Lakes Entomologist

The Cedar beetle family, Rhipiceridae, is recorded from Wisconsin for the first time. A single adult female of Sandalus niger was collected on a walkway along a forested path in south-central Wisconsin on 7 October 2000. This discovery represents not only the first record of Rhipiceridae from Wisconsin, but also the first record of the entire superfamily Dascilloidea, a relatively basal lineage of Elateriformia.

Ant-Plant Relationships In A Re-Created Tallgrass Prairie, Chris E. Petersen, Dhvani G. Dave, Charise L. Parker, Renee E. Petersen

The Great Lakes Entomologist

Relationships between the distributions of nesting ants and flora were investigated in a re-created tallgrass prairie located in northeastern Illinois. One-third of 167 randomly selected 1m2 quadrats in the prairie contained ant nests. Basal coverage of ground by tall grass shoots was greater in quadrats having ant nests than in those lacking ant nests. In addition, clumps of big bluestem (Andropogon gerardii) that were inhabited by the ant, Acanthomyops clavigera, had higher median rank densities than adjacent clumps lacking nests. The clumps also showed a negative correlation between big bluestem shoots/ cm2 and area occupied by the clump at …

Size Estimate Of A Local Population Of Brychius Hungerfordi (Coleoptera: Haliplidae), Michael Grant, Brian Scholtens, Robert Vande Kopple, Bert Ebbers

The Great Lakes Entomologist

Much of the natural history of the endangered crawling water beetle, Brychius hungerfordi, is unknown. Population estimates have only been surmised. We have measured, using a mark and recapture technique, a localize population of the beetle in a pool on the East Branch of the Maple River, Emmet County, Michigan. The average population during July 2001 was found to be 1052 individuals with a range of 43 (highest estimate – lowest estimate). A three-year study of the relative abundance of the beetle in the same pool suggests that the population has remained relatively constant.

Mating Success Of Gypsy Moth (Lepidoptera: Lymantriidae) Females In Southern Wisconsin, Ksenia Tcheslavskaia, Carlyle C. Brewster, Alexei A. Sharov

The Great Lakes Entomologist

Mating success of laboratory-reared gypsy moth Lymantria dispar (L.) females exposed for 24 hr on tree boles and its relationship to male moth counts in pheromone-baited traps was studied in southern Wisconsin. The relationship between mating probability of gypsy moth females and male moth counts in traps corresponded to an exponential model that can be used for predicting mating probabilities in sparse isolated populations. Relative attractiveness of females compared with traps was 0.23, which is similar to earlier estimated relative attractiveness of females in Virginia. The mortality of females from predation, however, was found to be significantly lower in Wisconsin …

Creb-Binding Protein Plays Key Roles In Juvenile Hormone Action In The Red Flour Beetle, Tribolium Castaneum, Jingjing Xu, Amit Roy, Subba Reddy Palli

Entomology Faculty Publications

Juvenile hormones (JH) and ecdysteroids regulate many biological and metabolic processes. CREB-binding protein (CBP) is a transcriptional co-regulator with histone acetyltransferase (HAT) activity. Therefore, CBP is involved in activation of many transcription factors that regulate expression of genes associated with postembryonic development in insects. However, the function of CBP in JH action in insects is not well understood. Hence, we studied the role of CBP in JH action in the red flour beetle, Tribolium castaneum and the Tribolium cell line. CBP knockdown caused a decrease in JH induction of genes, Kr-h1, 4EBP and G13402 in T. castaneum larvae, adults and …

The Invasive Med/Q Bemisia Tabaci Genome: A Tale Of Gene Loss And Gene Gain, Wen Xie, Xin Yang, Chunhai Chen, Zezhong Yang, Litao Guo, Dan Wang, Jinqun Huang, Hailin Zhang, Yanan Wen, Jinyang Zhao, Qingjun Wu, Shaoli Wang, Brad S. Coates, Xuguo Zhou, Youjun Zhang

Entomology Faculty Publications

Background: Sweetpotato whitefly, Bemisia tabaci MED/Q and MEAM1/B, are two economically important invasive species that cause considerable damages to agriculture crops through direct feeding and indirect vectoring of plant pathogens. Recently, a draft genome of B. tabaci MED/Q has been assembled. In this study, we focus on the genomic comparison between MED/Q and MEAM1/B, with a special interest in MED/Q’s genomic signatures that may contribute to the highly invasive nature of this emerging insect pest.

Results: The genomes of both species share similarity in syntenic blocks, but have significant divergence in the gene coding sequence. Expansion of cytochrome P450 monooxygenases …

Discriminations Of Color And Pattern On Artificial Flowers By Male And Female Bumble Bees, Bombus Impatiens (Hymenoptera: Apidae), Dana Church, Catherine Plowright, Diana Loyer

The Great Lakes Entomologist

This study examined the performance of male bumble bees (Bombus impatiens) in color and pattern discriminations and compared it to that of female bees. Bees were trained to forage from rewarding (S+) and unrewarding (S-) artificial flowers which differed in color (blue vs yellow) or pattern (e.g., concen­tric vs radial). Learning of the discrimination by the bees was then assessed by examining choice proportions of different flower types while none of the flowers offered reward. Color discriminations were made with 98% accuracy by the males, and the choice proportion was no different for females. Pattern discriminations were very poor or …

Tiphia Vernalis (Hymenoptera: Tiphiidae) Parasitizing Oriental Beetle, Anomala Orientalis (Coleoptera: Scarabaeidae) In A Nursery, Michael E. Reding, Michael G. Klein

The Great Lakes Entomologist

(excerpt)

Tiphia vernalis Rohwer is native to China, Japan, and Korea where it is an external parasite of Popillia spp. (King 1931). It was released into the United States from China and Korea during the mid-1920s through early 30s (Fleming 1968). After it became established in the United States, releases were made from domestic sources beginning in 1931 (King et al. 1951). Tiphia vernalis was released into Ohio sporadically during 1936-1953 (King et al.1951). Tiphia vernalis has been reported parasitizing Popillia spp. (P. quadriguttata (Fabricius) in Korea; P. chinensis (Frivaldsky) and P. formosana (Arrow) in China; and P. japonica …

Second Location For Two Rare Odonata In Ohio, Nannothemis Bella And Ladona Julia, (Odonata: Libellulidae) Discovered At Singer Lake Bog, Summit County, Ohio., Robert C. Glotzhober, Eric Chapman

The Great Lakes Entomologist

Previously the dragonflies (Odonata, Libellulidae) Ladona julia and Nannothemis bella were known in Ohio from only one extant population each: L. julia from extreme northwest Ohio in Williams County and N. bella from west-central Ohio in Champaign County. During the summer of 2000 populations of each of these species were found in close proximity to each other at Singer Lake, a wetlands complex in southern Summit County in northeastern Ohio. This new location is also home to a population of another rare Ohio dragonfly, Dorocordulia libera (Odonata, Corduliidae) that was discovered during 1999. The Singer Lake wetlands are proving to …

The Great Lakes Entomologist

This paper documents the first occurrence of Hexacola neoscatellae, a shore fly parasitoid, in Canada. The discovery of H. neoscatellae is significant because currently there are no suitable biological control agents available for shore fly control to the floriculture industry.

Distribution Of Terrestrial Isopods (Crustacea: Isopoda) Throughout Michigan: Early Results, Jennifer L. Stoyenoff

The Great Lakes Entomologist

Results are reported from the first two years of a multi-year study on the distribution of terrestrial isopods (Crustacea: Isopoda) in Michigan. During the first year of the study (1997), intensive investigations were carried out us­ing pitfall traps in a small area of Midland, MI. The study was resumed in 2001 with opportunistic collection and hand-sorting of litter samples for terrestrial isopods throughout 30 Michigan counties. As a result of this data collection, the species Haplophthalmus danicus, previously unrecorded in the state, has been located in seven counties, and 83 new county records have been established for eight other …
