Ecological Determination Of The Hour Of Nest Opening By An Ant, A. Dwight Smith

Loma Linda University Electronic Theses, Dissertations & Projects

The timing of daily opening of the nest entrance by the red harvester ant Popnomyrmex californicus was studied during all four seasons. Multiple regression analysis of several , environmental variables shows that the variation from day to day in mean opening time can be attributed to temperature differences, with the time that a given temperature was reached being the most important single variable for the autumn days studied. An equation incorporating this and the minimum temperature was sufficient to specify the mean opening time to within a few minutes. For the spring days, it was necessary to combine sunrise time …

Western Corn Rootworm Egg Distribution And Adult Emergence Under Two Corn Tillage Systems, K. P. Pruess, G. T. Weekman, B. R. Somerhalder

Department of Entomology: Faculty Publications

Under a conventional plowing system, eggs of Diabrotica virgifera LeConte were more uniformly deposited in the top 6 inches of the soil profile than under a reduced strip-tillage system which resulted in heaviest egg deposition in the furrow or ridge. Equal numbers of eggs were deposited in both systems. After corn was planted, more eggs occurred in the seedling zone in conventionally planted corn; in till-plant corn, eggs were removed from the seed row, and eggs concentrated in the furrow were covered with additional soil. Adult emergence was 5–10 days later in till-plant corn than in the conventional tillage system.

The Biology Of Choristoneura Houstonana (Lepidoptera: Tortricidae), A Pest Of Juniperus Species, E. A. Heinrichs, Hugh E. Thompson

Department of Entomology: Faculty Publications

Choristoneura houstonana (Grote) lays eggs singly in July. Egg development ranged from 8 to 11 days, with the majority hatching 10 days after oviposition. Larvae are solitary, and mine during early instars, but later instars feed externally on leaves in shelters made by webbing foliage together. There is one generation each year, and overwintering occurs in a hibernaculum, in mined leaves. Field-collected head-capsule width frequencies indicated nine larval instars. Rearing larvae on seedling junipers indoors indicated a range of 8–11 instars. Pupation occurs during June and July in the shelter where the larva feeds. The pupal stage lasted about 10 …

Biometrical Study Of Morphology And Development Of The Pennsylvanian Trilobite Ameura Sangamonensis (Meek And Worthen), Roger K. Pabian, J. A. Fagerstrom

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

Biometrical study of morphology and development in a sample of 100 cranidia, 94 pygidia, 26 free cheeks, and 9 complete specimens of the trilobite Ameura sangamonensis (Meek and Worthen) from the Bonner Springs Shale (Pennsylvanian; Missouri Series) in eastern Nebraska indicates that the dominant growth pattern was isometric. Evidence supporting this conclusion consists of rectilinear size relations among eight pairs of cranidial dimensions, three pairs of pygidial dimensions, and three pairs of dimensions of the free cheeks. Qualitative changes in pygidial morphology during development include a progressive decrease in prominence of the border, increasing width of the posterior border relative …

Seasonal Lipid Content Of Bagworm Larvae, E. A. Heinrichs

Department of Entomology: Faculty Publications

It is common knowledge to many who have attempted to control bagworms Thyridopteryx sp., that early instars are fairly easy to control, while later larval stages are less susceptible to insecticides. Studies of other insects (Bennett and Thomas 1963, Munson and Gottlieb 1953, Munson et al. 1954, Reier et al. 1953) have shown that as the lipid content increases, the susceptibility to insecticides (especially chlorinated hydrocarbons) decreases. To determine whether the lipid content of the bagworm larva increased with age a series of lipid extractions was conducted.

Effect Of Substrate Types On Aquatic Insect Distribution, Henry L. Bell

Journal of the Minnesota Academy of Science

Selective Breeding Of Honeybees For Alfalfa Pollen: Fifth Generation And Backcrosses, William P. Nye, Otto Mackensen

All PIRU Publications

Selection within lines for honeybees showing strong and weak tendencies toward collection of alfalfa pollen was continued through the fifth generation. In the line with a strong tendency (high line), the average percentage of pollen collectors collecting alfalfa pollen increased from 66% in the fourth generation to 85% in the fifth. In the line with the weak tendency (low line), the corresponding percentages were 8% and 18 %. Backcrosses of the two lines resulted in an intermediate mean. At Howell, Utah, where other pollen than alfalfa was scarce, the percentages were 99% and 53% for the high and low lines …

A Brief History Of The Namru-3 Medical Zoology Program, Harry Hoogstraal

United States Naval Medical Research Unit 3: Publications

The NAMRU-3 Medical Zoology program began during Easter week of 1950. We had just closed the NAMRU-3 field station at Torit, in Equatoria Province of soulheastern Sudan, and were heading homeward to the United States. However, the offer to remain in Egypt for a year or two to develop a Medical Zoology department at NAMRU-3 provided an interesting challenge after working for several years in tropical forests and grasslands of Africa and other continents. We shall briefly describe subsequent events under four headings: (1) Medical Zoology in Egypt, (2) Ticks and Tickborne Diseases of the World, (3) Kala Azar in …

Wheat Weevil And The Farmer, Clee Francis Howard Jenkins, G. D. Rimes

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

INSECT pests have been taking toll of mans' crops and herds since very early times and despite modern control techniques the annual loss is still very high.

It has been estimated that damage to stored grain alone may average 10 per cent, per year, or, in terms of the West Australian harvest, a loss by weevils of about twice the capacity of the large Midland Junction bin.

The Sterile-Male Technique For Control Of Mosquitos: A Field Cage Study With Anopheles Quadrimaculatus, R. S. Patterson, C. S. Lofgren, M. D. Boston

Entomology Papers from Other Sources

The use of sterile males to control a cage population of a laboratory strain of Anopheles quadrimaculatus was not successful, even though 80 to 90% of the females laid sterile egg clutches. At the ratio of sterile males to normal males being used, complete sterility should have been quickly achieved. Subsequent studies of the survival and sexual vigor of these sterile males indicated that only a small number, about 5%, of the released males were actually competing with normal males for the uninseminated females. Thus, until a more hardy and sexually vigorous male A. quadrimaculatus can be reared in the …

Spring Dispersal Of Some Leafhoppers And Aphids, A. G. Peterson, J. D. Bates, R. S. Saini

Journal of the Minnesota Academy of Science

Two species of leafhoppers and four species of cereal aphids appear to be transported to Minnesota each spring on strong winds from the south or southwest. The aster leafhopper, Macrosteles fascifrons (Stal); the English grain aphid, Macrosiphum avenae (Fabr.); the apple grain aphid, Rhopalosiphum fitchii (Sand.); and the greenbug, Schizaphis graminum (Rond.), usually arrive in Minnesota during late April or early May. Weather conditions favorable for northward movement of these insects consist of a high pressure area over the eastern states, a low pressure area over the western plains, and the resulting strong, persistent, south wind which is often called …
