Cicindela. Vol. I., No. I. March, 1969. Edited by R.L. Huber, R.G. Graves and H.L. Willis. Osseo, Minnesota. 24 pp. $3.50/volume.
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
Projected Red Pine Yields from Aldrin-Treated and Untreated Stands Damaged by White Grubs and Other Agents
(excerpt)
Young red pines, Pinus resinosa Ait., during the first few years after planting in the Lake States, are vulnerable to several injurious agents, including white grubs, the larvae of May beetles, Phyllophaga spp. (Kittredge, 1929; Craighead, 1950). The pesticide aldrin3 has frequently been applied at planting time to protect seedlings from white grubs. More than 12,000 acres of national forest land were treated with aldrin from 1960 to 1967 in the Lake States; almost 10,000 of these were on the Hiawatha National Forest (Fowler, 1973)
Relative Susceptibilities of Three Ponderosa Pine Sources to European Pine Sawfly (Hymenoptera: Diprionidae) Attack in Michigan
[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
White Grub Populations, Phyllophaga Spp., in Relation to Damaged Red Pine Seedlings in Michigan and Wisconsin Plantations (Coleoptera: Scarabaeidae)
Excerpt: White grubs (Coleoptera, Scarabaeidae), the larvae of May and related beetles, are destructive pests in some young pine plantations in the Lake States Region. They live in the soil and feed on roots of trees and other vegetation. Larvae chew off the smaller and girdle the ldrger roots of pine seedlings, and consequently reduce growth, weaken, and kill the seedlings.
Recommendations against planti.ng or for control measures have been made for grub population densities ranging from 4.4/ft2, 2.0/ft.3, 2.0/ft.\u27, down to 0.5 grubs/ft2 of soil surface (Stone and Schwardt, 1943; Rudolf, 1950; Speers and Schmiege, 1961 ; Shenefelt et al., 1954).
A study was carried out to accurately assess or predict grub-caused mortality and damage to seedlings from a given grub population density. This information is necessary for making control recommendations
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
Notes on the Biology and Parasitoids of the Sweet Fern Underwing (Lepidoptera: Noctuidae) in Michigan
(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
Shoreline Aggregation Behavior of Adults of a Midge, Chironomus Sp. (Diptera: Chironomidae) at Solberg Lake, Wisconsin
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)
