\u3ci\u3eUrophora Quadrifasciata\u3c/i\u3e (Diptera: Tephritidae), An Introduced Seedhead Fly New to Midwestern North America

The Old World tephritid Urophora quadrifasciata, a gall-inducing seed- head fly, was released in western and eastern North America for the biological control of knapweeds, Centaurea spp. (Asteraceae). Its establishment in the West (BC, CA, ID, MT, OR, WA) and in the East (CT, MA, MD, NH, NJ, NY, PA, RI, VA, VT, WV) has been previously reported. Collections from eastern Minnesota and western Michigan in 1995 are the first for the Northcentral region of North America

Pentatomoidea (Hemiptera: Pentatomidae, Scutelleridae) Associated With the Dioecious Shrub Florida Rosemary, \u3ci\u3eCeratiola Ericoides\u3c/i\u3e (Ericaceae)

Florida rosemary (Ceratiola ericoides), an ericaceous shrub with needlelike leaves, is characteristic of Florida scrubs and certain other xeric plant communities of well-drained sands. The plant is dioecious, its inconspicuous male and female flowers borne on separate individuals. From 2003 to 2012 (mainly 2007–2012), rosemary was sampled periodically (with all months included at least once during the period) in sand ridges of peninsular Florida and two riverine dunes in southeastern Georgia. Branches of male and female plants were tapped separately into a beating net. Sampling during the final three years was female-plant-biased to facilitate work on fruit- and seed-feeding heteropterans. Nymphs and adults of three pentatomoid species were found on C. ericoides: the pentatomid Thyanta custator custator (F.) and scutellerids Diolcus chrysorrhoeus (F.) and Homaemus proteus Stål. Only T. c. custator was taken in both states, occurring at 19 sites (19 nymphs, 53 adults); D. chrysorrhoeus was found in Florida at 16 sites (9 nymphs, 165 adults). The collection of T. c. custator and D. chrysorrhoeus from female rosemary plants essentially throughout the sampling period, including nymphs, exuviae, and mating pairs, coupled with their near absence from male plants, suggests that the bugs are not incidental on rosemary but feed on its fruits. Whether either species completes its life cycle on rosemary is unknown. Three nymphs and eight adults of the little-known H. proteus were collected from female rosemary plants at four sites, but the scutellerid’s relationship to C. ericoides remains to be determined. Briefly noted is the collection of the pentatomid Euschistus obscurus (Palisot de Beauvois) and scutellerid Stethaulax marmoratus (Say), whose adults were collected infrequently on female rosemary plants in Florida

Holarctic Insects Adventive in Michigan: New and Additional Records (Homoptera, Heteroptera, Coleoptera, Neuroptera)

Fourteen European insects in the Homoptera (4 species), Heteroptera (5), Coleoptera (4), and Neuroptera (1) are reported from Michigan. Ten are new state records (one new Ohio record is given). The point of entry for most of the species is assumed to be the northeastern United States or Maritime Provinces of Canada. Possibilities of dispersal (natural and human-assisted) from centers of introduction in the Northeast, multiple introductions from Europe, and direct entry into the Great Lakes region are discussed

Late Lilac, \u3ci\u3eSyringa Villosa\u3c/i\u3e: New Host of the Lace Bug \u3ci\u3eLeptoypha Mutica\u3c/i\u3e (Heteroptera: Tingidae)

The lace bug Leptoypha mutica, a specialist on trees and shrubs of the Oleaceae, feeds mainly on ash, Fraxinus spp., and fringetree, Chionanthus virginicus. In July 1987 and 1988, nymphs and adults were observed on late lilac, Syringa villosa, in a landscape planting in northwestern Pennsylvania. Infested leaves showed chlorotic blotches, the damage concentrated around midribs and lateral veins. This is the first report of lilac serving as a host for a North American tingid

\u3ci\u3eSlaterobius Insignis\u3c/i\u3e (Heteroptera: Lygaeidae): Association With Granite Ledges and Outcrops in Minnesota

Adults and late-instar nymphs of the wide-ranging myrmecomorphic lygaeid Slaterobius insignis were collected in northern Minnesota from cracks of granite outcrops and ledges, a habitat differing somewhat from that reported elsewhere. At two of the four sites, S. insignis was observed in plant-and litter-filled cracks with nymphs of the lygaeid Trapezonotus arenarius. All adults of the polymorphic S. insignis observed on granite were brachypters that belonged to the dark color morph of the species. Individuals occurred on rock surfaces with a black ant, Formica subsericea, which they resembled in appearance and behavior

The Pentatomoidea (Hemiptera) of Northeastern North America with Emphasis on the Fauna of Illinois. J. E. McPherson. 240 pages. Southern Illinois University Press, Carbondale, 1982. $30.00.

(excerpt) Among the most conspicuous of the true bugs are the pentatomoid Hemiptera, stink bugs and their relatives, many of which are large, or moderately so, and brightly colored. Unwary berry pickers probably can recount an unpleasant experience with fruit tainted by the noisome odor of a stink bug, and the characteristic, barrel-shaped eggs of most Pentatomidae, often ornate and arranged in neat rows, have evoked the wonderment of naturalists and prompted numerous technical descriptions from entomologists. Contributing to the importance of this group are the crop losses inflicted by certain plant-feeding species and the destruction of insect pests by predatory stink bugs (Asopinae)

Hawthorn Lace Bug (Hemiptera: Tingidae), First Record of Injury to Roses, with a Review of Host Plants

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

John Robert Eyer: Entomological Work in Pennsylvania and Lists of Publications

(excerpt) John Robert Eyer died at Carlsbad, New Mexico, on January 30, 1976. J. G. Watts and W. A. Iselin (1976), his former colleagues in the Department of Botany and Entomology at New Mexico State University, Las Cruces, wrote an obituary and quite naturally focused on Eyer\u27s work at the University\u27s Agricultural Experiment Station. Since Dr. Eyer\u27s first positions in entomology were in Pennsylvania, we have prepared this biographical sketch to preserve the record of his early accomplishments

Fourlined Plant Bug (Hemiptera: Miridae), a Reappraisal: Life History, Host Plants, and Plant Response to Feeding

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\u27 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 seeming to appear simultaneously with insertion of the bug\u27s stylets. Histolysis of plant tissues, the most rapid response to mind feeding yet reported, is attributed to a potent lipid enzyme whose active constituents are under investigation
