    Excerpt: Cicindela, a new entomological journal for cicindelophiles, is an experiment in extreme specialization. Supporting enthusiasts chose the scope as world-wide Cicindelidae over the alternatives of world-wide Caraboidea (Carabidae and Cicindelidae), and Nearctic Caraboidea, or Nearctic Cicindelidae. Ronald L. Huber, instigator and spearhead of the publication, proposes to publish it in quarterly numbers to total approximately 100 pages per volume each year

    Relative Susceptibilities of Three Ponderosa Pine Sources to European Pine Sawfly (Hymenoptera: Diprionidae) Attack in Michigan

    Get PDF
    [excerpt] Accidentally introduced into New Jersey about 1925, the European pine sawfly, Neodiprion sertifer (Geoffroy), now inhabits most of the Northeastern and North Central States and Ontario, Canada. Red pine, Pinus resinosa Aiton, and most other native and exotic pines within its range are susceptible to attack. Few attack records are available for ponderosa pine, P. ponderosa Douglas ex Lawson, because this pine is uncommon in eastern North America. Soraci (1939) ob- served egg clusters and larval feeding on planted red and ponderosa pine in New Jersey; Benjamin et al. (1955) found egg clusters on ponderosa pine in Illinois and recorded more intensive attacks on red pines nearby. However, quantitative data on the relative susceptibility of ponderosa pine to sawfly attack have never been reported

    Spatial Distribution of Egg Clusters of the European Pine Sawfly \u3ci\u3eNeodiprion Sertifer\u3c/i\u3e (Geoff.) in Young Pine Plantations in Michigan

    (excerpt) The European pine sawfly, Neodiprion sertifer (Geoffroy), is a perennial problem in young pine plantations in Eastern North America. Scotch pine, Pinus sylvestris L., and red pine, P. resinom Ait., are its principal hosts. During recent behavioral studies of this sawfly in Michigan, spatial distribution patterns were determined in order to rapidly survey population levels in young pine plantations (Wilson and Gerrard, 1971). Earlier, Lyons (1964b) presented some distributional data on N. sertifer in regard to population sampling. Wright et al. (1967) and Hattemer et al. (1969) discussed N. sertifer distributions in Scotch pine and mixed pine species provenancz plantings

    The Capability of Some Butterflies as Carriers of Common Milkweed Pollen

    The common milkweed, Asclepias syriaca L., is remarkably adapted for cross pollination by insects. Its pollen sacs (pollinia) are often found attached to the appendages of bees, wasps, butterflies, and other insects that visit milkweed for its nectar (Judd, 1955; Matheson, 1951 ; Muller, 1883). In the summer of 1966 and 1967 I collected numerous pierid and nymphalid butterflies associated with milkweed plants in Michigan in order to examine them for their pollen-carrying capability. Species of butterflies collected were Colias interior Scudder, C. eurytheme Boisduval, Pieris rapae (L.). and Speyeria aphrodite (Fab.). These insects were taken while feeding on or flying near milkweed plants between 3 July and 22 July each year--the period when milkweed was in full bloom--in Crawford, Montmorency, and Oscoda Counties, Michigan

    Shoreline Aggregation Behavior of Adults of a Midge, Chironomus Sp. (Diptera: Chironomidae) at Solberg Lake, Wisconsin

    Get PDF
    Excerpt: Adult chironomid midges are well known to visitors at northern Wisconsin lakes during the spring and summer. Although the larval stages of chironomids supplement the diet of fish, the adults are often a nuisance because they aggregate in huge aerial swarms near beaches, collect at lights, alight on various objects including people, and deposit green specks wherever they rest. The most familiar midge in Wisconsin is Chirononmus plumosus (L.) which has been studied at Lake Pepin (Johnson and Munger, 1930) and at Lake Winnebago (Burrill, 1913; Hilsenhoff, 1959,1966,1967)

    Location and Condition of Whitemarked Tussock Moth (Lepidoptera: Lymantriidae) Cocoons in a Michigan Black Walnut Plantation

    Get PDF
    Whitemarked tussock moth, Orgyia leucostigma, cocoons were monitored in a black walnut, Juglans nigra, plantation in Michigan from 1978 to 1981. Larvae spun cocoons on the exposed bark of the bole (29.6070), in crevices on the bole formed by pruning wounds (17.5%), beneath limbs (24.2%), and in branch crotches (28.7%). Parasites and predators destroyed 88% of the pupae in their cocoons. The tussock moth population, although moderate to high in the egg stage, decreased sufficiently in the larval stages each year to cause no more than 5010 defoliation to individual trees

    Life History and Outbreaks of an Oak Leafroller, Archips Semiferanus (Lepidoptera: Tortricidae), in Michigan

    Get PDF
    In the late 1960\u27s an outbreak of yellow-green tortricid larvae occurred over hundreds of thousands of acres of red oaks in northeastern Lower Michigan. At first the insect was thought to be the fruit tree leafroller, Archips argyrospilus (Walker); adult specimens, however, were identified by Freeman as A. serniferanus Walker. On forest lands oak or pine was the preferred cover type. In urban areas, the problem was acute where red oaks were the predominant shade tree. In 1969 and 1970 I observed this insect to learn about its life history, habits, and distribution. Besides regular field collections, some cage studies and laboratory rearings were done

    Notes on the Biology and Parasitoids of the Sweet Fern Underwing (Lepidoptera: Noctuidae) in Michigan

    Get PDF
    (excerpt) The sweet fern underwing, Catocala antinympha (Hubner), sometimes called the wayward nymph (Holland, 1968), is one of several lepidopterous defoliators of sweet fern, Comptonia peregrina (L.) Coult. Investigators have dealt only briefly with this insect because it is difficult to collect and rear in quantity and consequently, its biology is poorly known. The early works are basically taxonomic treatises. Barnes and McDunnough (1918b) updated the synonomy which remains intact to date. They placed antinympha as belonging to their Group IV (Catabapta Hulst), a group comprising Myrica (=Comptonia) feeders. Their treatise presents excellent color reproductions of the adult and mature larva. Previously, Beutenmuller (1902) described the six larval instars. The present paper adds a Little more to the distribution, biology, and habits of the sweet fern underwing, with emphasis on Michigan, and includes the known parasitoids and the effect of some of them on the size of the larval head capsule

    Some Relative Humidity Reactions of the Wood-Louse, Cylisticus Convexus (Isopoda: Porcellionidae) in an Olfactometer

    Generally, wood-lice are confined to habitats where the saturation deficit is low and damp surfaces are available. Cylisticus convexus (De Geer) is one of many species that are found in a relatively wet habitat (Edney, 1954). Allee (1926) was the first to report on some moisture reactions of C. convexus. When he supplied them with dry filter paper, they aggregated strongly to reduce water loss. When he supplied them with very dry paper in a dry atmosphere, the isopods all moved about frantically until they died. Those placed on moist filter paper, however, moved about slowly and remained apart--reacting very much as if they were in their normal habitat. Since a colony of C. convexus was available to me, I proceeded to investigate further the moisture reactions of this isopod. Several experiments were undertaken to examine their behavior under different humidity conditions, and to determine their preferred range of humidity. All tests were made in an olfactometer

    Distribution, Abundance, and Some Habits of Larvae of Cicindela Hirticollis (Coleoptera: Cicindelidae) on a Lake Michigan Beach

    Get PDF
    In August 1965, numerous burrows of tiger beetle larvae were found on a short expanse of beach along the shore of Lake Michigan in Emmet Co., Mich. Several adults associated with the larvae were captured and identified as Cicindela hirticollis Say. Blanchard (1921) collected C. hirticollis a few miles south of this area in 1917, and reported he had not found it in the interior of either Emmet or Cheboygan counties. In an extensive survey of Michigan Cicindelidae, Graves (1963) found C. hirticollis to be restricted to the sandy shores of three of the Great Lakes. Apparently this insect is widespread in North America, since several investigators have reported it from beaches along the Atlantic and Pacific coasts (Davis, 1903; Dunn, 1891; Fox, 1910; Gould, 1834). Because of the high population of larvae on the Lake Michigan beach in 1965, the area was reexamined August 12, 1966 to measure the distribution and abundance of the larvae
