Collecting Slime Flux Feeding Coleoptera In Japan, Brett C. Ratcliffe
Collecting Slime Flux Feeding Coleoptera In Japan, Brett C. Ratcliffe
University of Nebraska State Museum: Entomology Papers
Sappy wounds of injured or diseased trees entice a wide variety of insects. Carter (1945) stated that when fluxing is prolific or long continued, air-borne bacteria, yeasts, and fungi contaminate the oozing sap, ferment it and produce the material called slime flux. Apparently the oozing flux is toxic to the flux site and so prevents callusing by the tree. Consequently, the same tree usually can be a good collecting site for insects from year to year. My stay in Japan spanned four years, and collecting at flux sites was one of the most fruitful areas of endeavor. As soon as …

A Study Of Insects Attacking Pinus Flexilis James Cones In Cache National Forest, Thomas Evan Nebeker
A Study Of Insects Attacking Pinus Flexilis James Cones In Cache National Forest, Thomas Evan Nebeker
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Six species of insects were found attacking limber pine cones from July 26, 1968, through October 4, 1969, in Cache National Forest. The three species considered of major importance are: Conophthorus flexilis Hopkins, Dioryctria abietella (D. & S.), and D. sp. near or disclusa Heinrich. The three minor species encountered are; Bradysia sp., Trogoderma parabile Beal, and Asynapta keeni (Foote). In addition to the major and minor cone pests three parasites, Apanteles sp. prob. starki Mason, Elacherus sp., and Hypopteromalus percussor Girault were found associated with the cone pests.
C. flexilis, which completely destroys the cone, was ranked as …
The Response Of Kentucky Bluegrass Turf To Insecticidal Treatments, E. A. Heinrichs, Leonard C. Lehman, Lloyd M. Callahan, C. J. Southards, Ellis L. Matheny
The Response Of Kentucky Bluegrass Turf To Insecticidal Treatments, E. A. Heinrichs, Leonard C. Lehman, Lloyd M. Callahan, C. J. Southards, Ellis L. Matheny
Department of Entomology: Faculty Publications
The most common insect pests of Kentucky bluegrass (Poa pratensis L.) in Tennessee are sod webworms and white grubs. Attempts to control these insects with insecticides has, at times, resulted in the entire destruction of the lawn by sod webworms. Pass (1965) has shown that applications of aldrin, chlordane, and dieldrin increased the webworm population 2-3 fold. Streu and Vasvary (1966) found the same phenomenon in chinch bug control. Both Pass and Streu believed that this population increase of the target pest may have been related to an interference in some population-limiting mechanism, such as the natural enemies, but …

The Evolution Of Parasitism Among Bees, George E. Bohart
The Evolution Of Parasitism Among Bees, George E. Bohart
Faculty Honor Lectures
Before discussing parasitic bees, I will present a rough outline of the biology of "ordinary" or non-parasitic bees. The superfamily Apoidea (bees) includes perhaps 25,000 or 30,000 species divided into nine families by recent authorities (Stephen, Bohart, Torchio, 1969) . A common biological thread holding this vast assemblage together is the provision by adults of pollen and nectar for their young. Only in the honey bees (the genus Apis which includes four species) are the larvae fed primarily on a different substance (a secretion of the pharyngeal glands) , and even this is derived from pollen and honey eaten by …
Tb43: Field Recognition Of The Larvae Of Native Coccinellidae Common To The Potato Fields Of Aroostook County, R. H. Storch
Tb43: Field Recognition Of The Larvae Of Native Coccinellidae Common To The Potato Fields Of Aroostook County, R. H. Storch
Technical Bulletins
The adult beetles of the family Coccinellidae are the well-known ladybird beetles or ladybugs. The larvae and adults of the subfamily Coccinellinae are considered beneficial because they feed on pest species, mainly aphids and scale insects. This study was undertaken to provide a means of recognizing the larvae of native coccinellids found in or around the potato fields of Aroostook County. For our purposes, it is desirable to be able to identify the insect quickly and without killing it. Thus, the larval color pattern was chosen as a possible means of identification.

Screening Of Chemosterilants Against The Southern House Mosquito Culex Pipiens Quinquefasciatus, M. D. Boston, R. S. Patterson, C. S. Lofgren
Entomology Papers from Other Sources
In view of the current interest in the use of sterile males to control or eradicate some species of mosquitoes, information is needed about chemicals or other methods that induce sterility in these insects. Thus, at the Insects Affecting Man Investigations Laboratory at Gainesville, Fla., we have begun to evaluate the sterilizing effect of chemicals on the southern house mosquito, Culex pipiens quinquefasciatus Say.

Entomology Papers from Other Sources
The release of 8,400 to 18,000 males per day of Culex pipiens quinquefasciatus Say which had been exposed to a sterilizing agent (thiotepa), suppressed and eliminated an indigenous population of this mosquito on an island off the cost of Florida in a 10 week period. Sterile males were effective in seeking out and mating with females on the island.
A New Tribe Of Saber-Toothed Cats (Barbourofelini) From The Pliocene Of North America, C. Bertrand Schultz, Marian R. Schultz, Larry D. Martin
A New Tribe Of Saber-Toothed Cats (Barbourofelini) From The Pliocene Of North America, C. Bertrand Schultz, Marian R. Schultz, Larry D. Martin
Bulletin of the University of Nebraska State Museum
A new genus of Pliocene Saber-toothed felid, Barbourofelis, is proposed and two new species B. fricki and B. morrisi are described. These two forms and other described material represent an unusual lineage of felids with long sabers, shortened crania, and massive postorbital bars. The tribal name Barbourofelini is proposed for this lineage which is presently known in North America from deposits ranging in age from Clarendonian through Kimballian. The Barbourofelini apparently migrated from Eurasia to North America in the Late Miocene or Early Pliocene. Sansanosmilus of the French Vindobonian appears to represent the ancestral stock of these cats. The …
Seasonal Abundance And Distribution Of Benthic Fauna Within A Pond, Ellis L. Matheny, E. A. Heinrichs
Seasonal Abundance And Distribution Of Benthic Fauna Within A Pond, Ellis L. Matheny, E. A. Heinrichs
Department of Entomology: Faculty Publications
A Tennessee pond was sampled weekly from June 18 to August 20, 1968, to determine quantitative differences among benthic organisms in sampling depths and dates. Annelids (Oligochaeta), Chironomidae larvae, and Chaoboridae larvae were the dominant organisms collected. Preferred depths existed for each group of organisms. Chaoboridae and Chironomidae exhibited distinct seasonal variations in numbers, with the population decreasing throughout the summer. Chaoboridae were the most and Chironomidae the least numerous of the 3 groups.
Susceptibility Of The Sod Webworm Pediasia Trisecta To Biological Control Agents, E. A. Heinrichs, C. J. Southards
Susceptibility Of The Sod Webworm Pediasia Trisecta To Biological Control Agents, E. A. Heinrichs, C. J. Southards
Department of Entomology: Faculty Publications
Homeowners in Tennessee have observed complete destruction of their lawns by the sod webworm a few months after applying an insecticide to control sod webworms or white grubs. The reason for this increase rather than a decrease in the webworm population is not perfectly understood. We believe, however, that the natural enemies of the webworm may be reduced to such low population levels that they exert very little control on the webworm. Thus, once the natural enemies are destroyed in a lawn, it may require several months or even years for them to increase to a population level necessary to …

Grain Aeration On The Farm, G D. Rimes
Journal of the Department of Agriculture, Western Australia, Series 4
ALTHOUGH grain aeration is a well known and widespread technique employed to prevent insect development in stored grain, the installations are invariably designed for large scale grain handling authorities.
Experimental work carried out in Western Australia over the last four storage seasons has shown that simple unsophisticated equipment can be of direct use in farm storage.

Fire Weather : A Guide For Application Of Meteorological Information To Forest Fire Control Operations, Mark J. Schroeder, Charles C. Buck
The Bark Beetles, Fuels, and Fire Bibliography
Weather is never static. It is always dynamic. Its interpretation is an art. The art of applying complex information about weather to the equally complex task of wildland fire control cannot be acquired easily-especially not by the mere reading of a book. The environment is in control in wildland firefighting. Free-burning fires are literally nourished by weather elements, atmospheric components, and atmospheric motion. Outguessing mother nature in order to win control is an extremely difficult task. We need to soothe her with understanding. We have attempted to present information in such a way that your daily and seasonal awareness of …

In a greenhouse, each nest of Pseudomasaris edwardsii (Cresson) was constructed of nectar-moistened soil, was solitary and was placed in open but concealed niches attached to a variety of substrates. The wasp anchored her egg by its posterior tip to the bottom of the cell, deposited a jellylike cylindrical provision composed of Phacelia pollen and nectar and constructed a cell cap. Soil carried to the nest was attached to the post genal surfaces of the female's head, and the pollen and nectar were transported in her honey stomach. Cells were clustered and attached to each other and to the substrate …

Control Of Hide Beetles, Department Of Agriculture, Western Australia
Control Of Hide Beetles, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
SKIN and hide beetles, members of the Dermestid beetle family, can cause serious damage to hides and skins.
British authorities are particularly concerned with the incidence of hide beetle infestation in sheepskins imported from Australia.
Local graziers and country abattoirs should pay attention to this problem as damage by hide beetles can greatly reduce the value of all types of skins.
