Biology and systematics of bee mites of the family Varroidae (Acari: Mesostigmata)

Creator:: Akratanakul, Pongthep
Abstract:: The bee mites Varroa jacobsoni Oudemaris and Euvarroa sinhai Delfinado and Baker (Family Varroidae) are reported for the first time from Thailand. V. jacobsoni was found parasitizing colonies of Apis cerana indica F. and A. mellifera L., E. sinhai was observed in association with drones of A. florea F. The...

Biological studies on the hemoflagellates of Oregon marine fishes and their potential leech vectors

Creator:: Burreson, Eugene Michael
Abstract:: Of 2,122 marine fishes belonging to 36 species collected in the vicinity of Newport, Oregon, 541 belonging to 8 species were infected with hemoflagellates. Four species of trypanosomes and three species of cryptobias were found in offshore fishes, but no hemoflagellates were observed in fishes from Yaquina Bay. Trypanosoma pacifica...

Some effects of sulfur fertilization on the nutrient value of subclover-grass forage

Creator:: McCarthy, Michael J.
Abstract:: Pastures consisting of mixtures of subclover (Trifolium subterraneum) and grasses have responded to sulfur fertilization on many sites in Douglas County, Oregon. The objectives of this study were to examine specific changes in forage quality which occur as sulfur is applied in excess of the amount required for maximum yield...

Alterations in growth, lipid metabolism and P:O ratios in mice fed Sterculia foetida oil

Creator:: Lehman, Michael Wesley
Abstract:: Cyclopropenoid fatty acids (CPFA) are natural components of cottonseed oil, a major food oil in the United States. The ability of CPFA to cause abnormal biochemical and physiological effects when fed to laboratory and farm animals has prompted an investigation of their effects on mice. Between 0.05 and 0.55% CPFA...

Temperature and moisture effects on stand establishment of seven winter wheat cultivars and selected progeny (Triticum Aestivum, L em thell

Creator:: Conway, Michael Patrick
Abstract:: Laboratory studies were conducted under different temperature and moisture regimes to evaluate the effects of temperature and moisture on stand establishment and seedling characteristics associated with stand establishment. Percent stand and days to 25% emergence were used as indexes of stand establishment. Seedling characteristics analyzed were: shoot length, coleoptile length,...

Potentiation of acute carbon tetrachloride hepatotoxicity by dietary exposure to chlorophenothane (DDT) in rats

Creator:: Koeferl, Michael Tallyn
Abstract:: There has been no toxicologic proof that the long-term, low-level exposure of man to chlorophenothane (DDT) is linked with an increased susceptibility to toxicity or disease. Acute pretreatment of rats with 75-100 mg/kg DDT has been demonstrated to potentiate CCI₄-induced hepatotoxicity in that species (McLean and McLean, 1966). Since the...

Soil moisture and temperature relationships under fallow in eastern Oregon

Creator:: Russelle, Michael P.
Abstract:: Time of stand establishment is a critical factor affecting yields of winter wheat and barley in the fallow-crop rotation areas of the Pacific Northwest. Farmers in this winter-rainfall region are dependent on residual moisture in the seed zone for germination, because significant precipitation does not usually occur until after the...

Aspects of mountain goat ecology, Wallowa Mountains, Oregon

Creator:: Vaughan, Michael R.
Abstract:: Twenty- six mountain goats (Oreamnos americanus), located between the Lostine River drainage and the East Fork Wallowa River drainage of the Wallowa Mountains, were monitored from June 1972 through June 1973. The age composition of the population was 76.9 percent adults and 11.5 percent each yearlings and kids. The addition...
