The pathogenicity of A. flavus on alkali bee larvae was studied
using sample materials from three nesting sites of these soil
inhabiting bees along the Oregon-Washington state line. Soil
saprophytes of the biosphere of the alkali bee were also studied.
Field observations and direction of soil cores from bee beds...
Ten helminth-free sheep were given two doses of 10,000,
X-irradiated, H. contortus, third stage larvae 30 days apart. These
animals and a group of ten non-vaccinated sheep were challenged
with 50,000, normal, H. contortus, third stage larvae 60 days
following the second vaccination. Antibody levels were measured
in both groups...
The study provides the details of the ethology of Megachile rotundata
(Fabricius), and presents preliminary observations on its
foraging and nesting behavior. Development from prepupae to adults
proceeds most rapidly at 32 degrees C., and is retarded when held
at lower and higher temperatures.
Male behavior is distinct from that...
Tissue obtained by punch biopsy from the antebrachial organ of
Lemur catta has been studied with the electron microscope. This study
describes the fine structure of the interstitial cells found between
apocrine sweat glands in the antebrachial organ. These large polygonal
cells are of three types: light cells, dark cells,...
