Epizootiology Of The Fungal Pathogen, Zoophthora Phytonomi (Zygomycetes: Entomophthorales) In Field Populations Of Alfalfa Weevil (Coleoptera: Curculionidae) Larvae In Illinois, Marilyn J. Morris, Stephen J. Roberts, Joseph V. Maddox, Edward J. Armbrust

The Great Lakes Entomologist

The influence of the fungal pathogen, Zoophthora phytonomi, on larvae of the alfalfa weevil, Hypera postica, was studied in three alfalfa fields in Illinois. Disease epizootics occurred in all three fields and disease onset was ob- served within a fairly narrow range of degree day accumulations. At the height of each epizootic, percentages of infected larvae were between 80 and 100%, and the fungus contributed to the collapse of the weevil population in each field. Percent parasitism by the larval parasitoids, Bathyplectes cur­culionis and B. anurus, was lower in our fields than is common in mid-season alfalfa …

Effects Of Hybrid Poplar (Salicaceae) Clone And Phenology On Gypsy Moth (Lepidoptera: Lymantriidae) Performance In Wisconsin, James J. Kruse, Kenneth F. Raffa

The Great Lakes Entomologist

Gypsy moth (Lymantria dispar) developmental interactions with two hybrid Populus species clones were studied in laboratory trials. Significant differences in larval performance were found between clones and within the same clone at different phenological states. No larvae were able to complete development on clone NM6. All gypsy moth larvae feeding on clone NC5271 survived when leafflush was synchronized with gypsy moth eclosion in early May. However, neonates feeding on NC5271 foliage in July experienced in- creased mortality. Weights of surviving gypsy moth larvae feeding on NC5271 foliage in May versus July were not significantly different.

Factors Affecting Abundance Of Adult Karner Blues (Lycaeides Melissa Samuelis) (Lepidoptera: Lycaenidae) In Wisconsin Surveys 1987-95, Ann B. Swengel, Scott R. Swengel

The Great Lakes Entomologist

At 141 pine-oak barrens in central and northwestern Wisconsin, 3,702 Karner blues (Lycaeides melissa samuelis Nabokov) were found in 81.1 hr of transect surveys during spring and 6,094 individuals in 116.6 hr during sum­mer. Adults offive other closely related lycaenids occurred with Karner blues. The percentage of Karner blue males (of sexed individuals) correlated nega- tively with advancing date within brood, exceeded 50% on peak date within brood, but showed wide variability on a given date. Karner blues occasionally occurred up to 800 m from the nearest larval host, or in tiny, isolated host stands. However, all individuals were …

Natural Enemies Of Cranberry Fruitworm, Acrobasis Vaccinii, (Lepidoptera: Pyraudae) In Michigan Highbush Blueberries, Dogulas A. Murray, Robert D. Kriegel, James W. Johnson, Angus J. Howitt

The Great Lakes Entomologist

A two-year study was conducted in Michigan highbush blueberries to determine the complex of parasitoids attacking cranberry fruitworm, Acrobasis vaccinii. Eight parasitoid species and one fungal pathogen were collected. Parasitism of collected hosts ranged from 6.6% to 28.1%. The more common larval parasitoid encountered was Campoletis patsuiketorum (Hymenoptera: Ichneumonidae). The more common parasitoid recovered from fruitworm hibernacula was Villa lateralis (Diptera: Bombyliidae). This study documented six unreported natural enemies of cranberry fruitworm, including C. patsuiketorum; V. lateralis; Diadegma compressum (Hymenoptera: Ichneumonidae); Compsilura concinnata (Diptera: Tachinidae); Memorilla pyste (Diptera: Tachinidae); an undescribed Microtypus species (Hymenoptera: Braconidae); and a fungal pathogen, …

Oviposition By The Banded Sunflower Moth, Cochylis Hospes (Lepidoptera: Cochylidae) In Response To Helianthus Annuus Pollen, John F. Barker, Sharon Grugel

The Great Lakes Entomologist

Oviposition on an artificial substrate by the banded sunflower moth Cochylis hospes Walsingham was examined in response to sunflower pollen (Helianthus annuus) and sunflower pollen extract. Sunflower pollen in quantities as small as 0.2 mg significantly reduced oviposition on an artificial substrate relative to a control without pollen. Aqueous pollen extract applied to the artificial substrate significantly reduced oviposition with respect to the control substrate that was treated with solvent. Banded sunflower moths have gained some reproductive or competitive advantage by ovipositing on the bracts of sunflower and a deterrent effect of pollen could, at least in part, have had …

Laboratory Rearing Of Lycaeides Melissa Samuelis (Lepidoptera: Lycaenidae), An Endangered Butterfly In Michigan, Catherine Papp Herms, Deborah G. Mccullough, Deborah L. Miller, Leah S. Bauer, Robert A. Haack

The Karner blue butterfly (Lycaeides melissa samuelis) is listed as a federally endangered species in the United States. It occurs in oak savanna and pine barren habitats from eastern Minnesota to New Hampshire. In 1994, we successfully reared Karner blue larvae under controlled laboratory conditions for experimental purposes, and report on those rearing methods here. We collected 20 female Karner blue adults of the spring generation from two areas in Michigan, and housed them in cages in an environmental chamber at 240 -26°C for 5 days. The female butterflies produced 154 eggs, of which 72 hatched in an average of …

Observations Of Incisalia Irus (Lepidoptera: Lycaenidael In Central Wisconsin 1988-95, Ann B. Swengel

The Great Lakes Entomologist

In surveys conducted during 1988-95, 164 individuals of the frosted elfin (Incisalia irus) were found, 139 of them during formal transects that totaled 92.9 hr and 179.4 km of survey effort during the frosted elfin flight period. Individuals were observed between 10 May and 14 June, with maximum . t spans in a single year of 27-31 days. Peak flight occurred just before or e beginning of peak flowering of the larval host, wild lupine (Lupinus perennis), and the first spring adults of Karner blue (Lycaeides melissa samuelis), also monophagous as larvae on wild lupine. Fourteen individuals exhibited …

A New Larval Record Of Perlinella Drymo (Plecoptera: Perlidae) For Michigan, Ethan Bright

The Great Lakes Entomologist

The presence of larvae of Perlinella drymo in Michigan is documented for the first time. A total of 7 individuals were collected from Iron Creek, a tributary of the River Raisin watershed located in southeastern Michigan. Gut analysis of one specimen provided evidence for a carnivorous diet. The location from which larvae were collected indicate a preference during winter for stabilized undercut banks with little or no flow and accumulated organic debris upon sand and gravel substrate.

Callibaetis Pretiosus (Ephemeroptera: Baetidae) From Pennsylvania: New Distribution Record, R. D. Waltz, James B. Munro

The Great Lakes Entomologist

A Migration Study Of Stelidota Geminata (Coleoptera: Nitidulidae), Roger N. Williams, M. Sean Ellis, Dan S. Fickle, Scott T. Bloom

The Great Lakes Entomologist

The strawberry sap beetle, Stelidota geminata (Say), is a major pest of strawberries in the northeastern United States. Further knowledge of the migratory habits of this insect pest can enhance the effectiveness of pest management strategies. This nitidulid was shown to migrate from its overwintering sites to one of its primary reproductive sites, strawberry fields, in late May. The beetle population peaked in the third week in July, 1993 in the strawberry field and then gradually declined. In 1994, the peak, as well as the total population, was much greater than in 1993. Furthermore, S. geminata was concentrated in the …

Evidence Of Pre-Imaginal Overwintering Of Diamondback Moth, Plutella Xylostella (Lepidoptera: Plutellidae) In Michigan, A. B. Idris, Edward J. Grafius

The Great Lakes Entomologist

We investigated the possibility of overwintering of the diamondback moth, Plutella xylostella L., in central Michigan. In the spring of 1993, counts of immature stages on brassicaceous weeds in a field previously planted to broccoli revealed a small but significant number of late instars that could not be attributed to oviposition of immigrant moths from the southern United States. We suggest that crop debris and snow cover played an important role in sheltering the larvae, which are known to tolerate sub·freezing temperatures. There was no indication of adult survival.

Spread Of Acentria Ephemerella (Lepidoptera: Pyralidae) In Central North America, B. G. Scholtens, G. J. Balogh

Occurrence Of Libellulid Dragonflies (Odonata: Libellulidae) In Southeastern Michigan And Adjacent Essex County, Ontario, Michael A. Kielb

The Great Lakes Entomologist

During 1994-1995 extensive field work was conducted in southeastern Michigan in an attempt to assess the species population and composition of libellulid dragonflies. Additional field work was conducted on dragonflies from southwestern Ontario migrating into southeastern Michigan. Comparisons were made with the species listed for this area 37 years earlier in Kormondy (1958) anticipating changes due to wetland reductions and the effects of pesticides. With one exception, all species listed in Kormondy were observed. Ad- ditionally, one species, unknown from this area as of 1958, was encountered.

A Michigan Record For Clytus Marginicollis (Coleoptera: Cerambycidae: Clytini), James E. Zablotny

The Great Lakes Entomologist

Clytus marginicollis Castlenau and Gory is a small, rarely collected clytine cerambycid endemic to coniferous forests of Eastern North America (Knull 1943, Linsley 1964). Gosling (1973) did not mention any records for it in his survey of Michigan cerambycids. Knull (1943) reports that this species probably occurs in Ohio but he had seen no specimens to confirm its presence.
