Effect On Residual And Contact Sprays On The Resistance Of The German Cockroach To Chlordane, G. S. Burden, C. S. Lofgren, J. B. Gahan

Entomology Papers from Other Sources

When contact sprays are applied for cockroach control, they are dispersed with the expectation that they will kill the insects actually in the room at that time but will have little if any effect on those that enter after the spraying has been completed. Residual sprays, which are applied to stationary objects such as walls or furniture, have the added advantage of also being toxic to those cockroaches that contact the treated surfaces at a later date. If the residual treatments actually kill a greater number of insects, they also may select for resistance at a much higher level and …

Resistance To The Chemical Sterilant, Apholate, In Aedes Aegypti, E. I. Hazard, C. S. Lofgren, D. B. Woodard, H. R. Ford, B. M. Glancey

Entomology Papers from Other Sources

lncreased resistance to the sterilizing efects of apholate was observed in two colonies of Aedes aegypti (L.) exposed in the larval stage of each generation to concentrations of apholate that induced about 90 to 40 percent sterility in the eggs laid by the ensuing adults.

Three Southeastern Minnesota Lakes As Possible Habitat For Hexagenia Mayflies, James R. Erickson

Journal of the Minnesota Academy of Science

Three small lakes near Winona, Minnesota, were sampled to determine if they supported populations of Hexagenia mayfly nymphs. Hexagenia nymphs were rare in Lake Winona and the Gravel Pit, and none was found in Crooked Slough. A low dissolved oxygen content at the mud-water interface is probably the limiting factor in Lake Winona and Crooked Slough. The limiting factor in the Gravel Pit is probably the bottom type.

The Darkling Beetles Of The Nevada Test Site (Coleoptera - Tenebrionidae), Willis A. Packham

Theses and Dissertations

In the desert areas of southwestern United States the Coleoptera, family Tenebrionidae, constitute a conspicuous part of the ground-dwelling insects. Most species are black or dull chestnut-brown. They are primarily nocturnal and during the day can be found under rocks, debris, loose bark, or in rodent burrows. On cloudy days they may be seen lumbering along the desert floor. Most tenebrionids feed on plant materials of various sorts. In August, 1959, Brigham Young University initiated an ecological study at the Nevada Test Site near Mercury in Nye County, Nevada. As part of that study, emphasis was given to the ground-dwelling …

Effects Of Food, Temperature, And Oviposition Site On Longevity And Fecundity Of The Army Cutworm, K. P. Pruess

Department of Entomology: Faculty Publications

Longevity of the army cutworm, Chorizagrotis auxiliaris (Grote), following mating was inversely related to temperature. Females lived longer than males at all temperatures, and food increased longevity of both sexes. Oviposition occurred at 70° and 55° but not at 32° F. None of the variables tested affected total fecundity but oviposition was completed sooner at 70° than at 55°, in sand as an oviposition site vs. paper toweling and by unfed than by fed moths. Starvation preceding oviposition did not affect fecundity but speeded completion of oviposition when moths were returned to favorable conditions.

The Bdellidae (Acarina) Of The Australian Realm, Warren T. Atyeo

Bulletin of the University of Nebraska State Museum (1924–2023)

Although primarily a systematic study, variations in the integumental striae and chaetotaxy of the legs are discussed. The genus Octobdellodes Atyeo, 1960 is synonymized with Bdellodes Oudemans, 1937 and the sugenus Cytobdella Mihelcic, 1958 is synonymized with Cyta von Heyden, 1826. The genus Bdellodes is divided into the subgenera Bdellodes and Hoploscirus Thor, 1937 (=Thoribdella Grandjean, 1938, new synonymy). Twenty-two species are now known to occur in New Zealand and the outlying islands. These include four known species: Bdella iconica, Bdellodes (Roploscirus) lapidaria, B. (R.) reticulata, and Cyta latirostris, and eighteen new species: Bdellodes (Bdellodes) harpax, B. (B.) oraria, …

Apparent Effects Of Refrigeration On The Rate Of Embryonic Development Of Mayfly (Hexagenia Limbata) Eggs, Roger Flattum

Journal of the Minnesota Academy of Science

Hunt (19 5 3) states that temperature is an important factor influencing the rate of embryonic development of Hexagenia (mayfly) eggs. Pasvogel (1962) has reported that 46 days is the time limit Hexagenia eggs can remain dormant at temperatures slightly above freezing. It was the object of this investigation to continue this line of research and to determine the effects of temperature on the embryonic development of Hexagenia limbata eggs.

Insect Pests Of Lawns., D G. Shedley

Journal of the Department of Agriculture, Western Australia, Series 4

Lawns provide a home for many and varied insects. Although a large number do little or no damage there are some which, if left unchecked, will make it impossible to maintain the grass in good condition.

SPRAYING with insecticides is not always the best answer to pest problems. Manuring, cutting and watering must be maintained at proper levels. In fact, if this is not done the attacks of at least some pests will be more severe.

Comparison Of Spider Populations Of Ground Stratum In Arkansas Pasture And Adjacent Cultivated Field, W. H. Whitcomb, Harriet Exline, Maxine Hite

Journal of the Arkansas Academy of Science

Of 64 species of spiders taken from the ground stratum of an Arkansas pasture and adjoining cotton field, only 26 were common to both. Twenty-two were collected only in the cotton field; 16, only in the pasture. Many of the 18 species of lycosids were taken in greater numbers in the cultivated field, especially Pardosa milvina and Lycosa helluo. Eight species of lycosids were found only in the cotton field; two, only in the pasture. Only Schizocosa avida, of the better represented lycosids, appeared to show no preference. Similar relationships are given for dictynids, erigonids, linyphiids, oxyopids, gnaphosids, clubionids, thomisids, …

Index Catalogue To Russian, Central And Eastern European, And Chinese Literature In Medical Entomology, Volume 1: Diptera, George Anastes

United States Naval Medical Research Unit 3: Publications

Over the past several years a large number of references from the USSR, Eastern Europe, and China have been collected dealing with arthropods of medical importance. These references were coded on keysort cards which made it possible to index as many as fifteen subject areas on one card. The usefulness of this indexing system was evident by the number of medical entomologists who used it in searching for references in their specialty. In response to requests from workers in the United States and other countries who did not have ready access to the index. it was decided to publish these …
