Observations Of The Biology Of Phasgonophora Sulcata (Hymenoptera: Chalcididae), A Larval Parasitoid Of The Twolined Chestnut Borer, Agrilus Bilineatus (Coleoptera: Buprestidae), In Wisconsin, R. A. Haack, D. M. Benjamin, B. A. Schuh

The Great Lakes Entomologist

Phasgorzophora sulcata Westwood was the principal larval parasitoid of Agrilus bilineatus (Weber) during a study conducted in a natural oak-hardwood forest in the Kettle Moraine State Forest, Jefferson County, Wisconsin. Mean percent larval parasitism was 10.5%. Mean A. bilineatus and P. sulcata densities were, respectively, 53.0 and 6.1 adults per square meter of bark. The theoretical developmental threshold temperatures for over- wintering A. bilineatus and P. sulcata larvae were 17.8" and 19.l0C, respectively. The peak flight period of P. sulcata (9 July 1980) occurred ca. 3 weeks after the A. bilineatus peak flight (18 June 1980) at about the time …

Oviposition By Dendrosoter Protuberans (Hymenoptera: Braconidae) On Larvae Of Scolytus Multistriatus (Coleoptera: Scolytidae) Occupied By Larvae Of Entedon Leucogramma (Hymenoptera: Eulophidae), Bruce H. Kennedy

The Great Lakes Entomologist

Dendrosoter protuberans (Nees) was introduced into the United States from France as a possible addition to the existing spectrum of hymenopterous parasites of the smaller European elm bark beetle, Scolytus multistriarus (Marsham). D. protuberans is an external parasite; it oviposits through bark onto or next to late-instar larvae of S. multistriatus (Kennedy 1970) (Fig. 1).

The Great Lakes Entomologist

(excerpt)

The two counties which share the northern tip of the Lower Peninsula of Michigan, Emmet on the west and Cheboygan on the east, have long been taken to define the principal "region" under study by the University of Michigan Biological Station, situated since 1909 on Douglas Lake in Cheboygan County near the Emmet County line.

A List Of The Butterflies (Lepidoptera: Papilionoidea) Of The La Rue-Pine Hills Ecological Area, R. W. Sites, J. E. Mcpherson

The Great Lakes Entomologist

A survey of the adult butterfly fauna of the La Rue-Pine Hills Ecological Area, Union County, Illinois, was conducted from March through July in 1979, and March through November in 1980. Forty nine species and subspecies were collected including all six papilionids known to occur in Illinois. Notes were taken on seasonal flight periods and butterfly-plant associations.

A North American Record For Valgus Hemipterus (Coleoptera: Scarabaeidae) And Information On Its Life Cycle, Joseph M. Mahar, Mark P. Oemke

The Great Lakes Entomologist

A rotting American elm log containing adults of Valgus hemipterus (L.) was discovered on 6 May 1980, at the Rose Lake Wildlife Experiment Station, Shiawassee County, Michigan. This appears to be the first record of this European species in North America. Larvae were collected in the summer, and pupae and teneral adults in the early fall suggesting a univoltine life cycle with the adults overwintering.

Seasonal And Vertical Distributions Of Planthoppers (Homoptera: Fulgoroidea) Within A Black Walnut Plantation, B. C. Weber, S. W. Wilson

The Great Lakes Entomologist

Information on the seasonal and vertical distributions of 34 species (eight families) of planthoppers was obtained from window trap collections in a North Carolina black walnut plantation in 15 and 1978. The most commonly collected species were Acanalonia conica (Acanaloniidael. Liburniella ornata (Delphacidae), Oliarus ecologus (Cixiidae), and O. quinquelineatus.

The First Report Of The Occurrence Of Mecidea Major (Hemiptera: Pentatomidae) In Illinois, J. E. Mcpherson, T. E. Vogt

The Great Lakes Entomologist

(excerpt)

Species of the phytophagous genus Mecidea occur in the subtropical and adjacent tem- perate parts of the world and appear to be associated with xerophytic and semixerophytic areas (Sailer, Proc. U.S. Natl. Mus. 102:471-505, 1952).

Type-Species Designation For The Jurassic Mayfly Genus Mesephemera (Ephemeroptera: Mesephemeridae), Michael D. Hubbard

The Great Lakes Entomologist

(excerpt)

Among the many new genera established by Anton Handlirsch in his monumental work "Die .fossilen Insekten und die Phylogenie der rezenten Fortnen: Ein Handbuch fur Palaontologen und Zoologen" (Wilhelm Engelman, Leipzig, 1906-1908) was a genus of Ephemer- optera for which he designated no type-species and for which one has still not been designated.

Key Parameter Comparisons Of Fungal Induced Mortality In Alfalfa Weevil Larvae (Coleoptera: Curculionidae), Robert J. Barney, Edward J. Armbrust

The Great Lakes Entomologist

Key parameters of alfalfa weevil larval mortality by Entornophthora phytonorni were compared weekly in three alfalfa fields. Rainfall appeared to be the overriding factor in seasonal larval infection rates.

Two Entomophthora Species Associated With Disease Epizootics Of The Alfalfa Weevil, Hypera Postica (Coleoptera: Curculionidae), In Ontario, D. G. Harcourt, J. C. Guppy, D. M. Macleod, D. Tyrrell

The Great Lakes Entomologist

Recent studies have shown that disease epizootics in Ontario populations of the alfalfa weevil, Hypera postica (Gyllenhal), are caused by a complex of two fungi.

Differences In Emergence Date And Size Between The Sexes Of Malacosoma Americanum The Eastern Tent Caterpillar (Lepidoptera: Lasiocampidae), Donald N. Bieman, J. A. Witter

The Great Lakes Entomologist

Malacosoma americanum males were smaller and began to pupate earlier than females. Since the sexes spent the same amount of time as pupae, males also emerged earlier. The adaptive significance of these results is discussed. Emergence data revealed an interesting sidelight; no moths emerged from cocoons inside tents.

Hawthorn Lace Bug (Hemiptera: Tingidae), First Record Of Injury To Roses, With A Review Of Host Plants, A. G. Wheeler Jr

The Great Lakes Entomologist

Hawthorn lace bug, Coryrhucha cydoniae (Fitch), is reported for the first time as damag- ing roses. Injury to climbing and hybrid Tea roses is described, and a list of known host plants is provided based on observations in Pennsylvania and review of literature. Preferred hosts are native and cultivated species of Amelanchier and Craraegus and ornamental Cotoneasrer and Pyracanrha. Damage to crabapple. fruit trees, mountain ash. and other rosaceous plants may occur when they are grown near more favored hosts.

Fourlined Plant Bug (Hemiptera: Miridae), A Reappraisal: Life History, Host Plants, And Plant Response To Feeding, A. G. Wheeler Jr, Gary L. Miller

The Great Lakes Entomologist

Phenology of the fourlined plant bug, Poecilocapsus lineatus, is presented for southcen- tral Pennsylvania; life history and habits are re-examined. Although breeding was previously thought to occur only on woody plants, we found that nymphs develop on numerous herbs. An extensive list of hosts, more than 250 species in 57 families, is compiled from the literature and the authors' observations; preferences are noted for plants in the Labiatae, Solanaceae, and Compositae. Damage consists of lesions on foliage, the size and shape of the spots varying with leaf texture, pubescence, and venation. Plant response to feeding is immediately visible, the lesions …
