From May through November 1963, a mosquito survey was
made in the city of Corvallis, Oregon. The information
obtained dealt with the species of mosquitoes found,
their seasonal occurrence and the location and nature of
their larval habitats. A quantitative and qualitative
analysis of larval and adult mosquito collections by...
Fannie canicularis is concentrated in areas where animal
husbandry is practiced and frequently comprises more than 50
percent of the fly population. There is a need for more critical
fly control where suburban expansion has invaded animal raising
regions. The purpose of this study is to investigate the use of...
The purpose of this study was to determine what insect species
occurred in waste water facilities at Corvallis, Oregon, and to
correlate these species with the chemical, physical, and biological
features common to these facilities. Data collected on a routine
basis included dissolved oxygen, temperature, algal density, and
insect population...
Ruelene was orally administered to three female sheep at a
dosage rate of 121.5 mg /kg. The cholinesterase (ChE) activity levels
of blood plasma, red blood cells (RBC), and mosquitoes (Aedes
aegypti) which had fed on the sheep were tested at various times
before and after dosage. Maximum depression of...
Chironomidae occurring in stabilization lagoons were studied
from 1964 to 1966 in Oregon. Observations of other insects and
their impact on the lagoon environment are included. Quantitative
data were obtained from two lagoons near Corvallis and qualitative
observations from preliminary work on two other lagoons are reported.
The objectives of...
Members of the family Simuliidae were studied in a single,
confined drainage system. In addition to determining the occurrence
and distribution of the species present, biological and ecological
observations were made. Specific measurements and observations
were accomplished to determine as much as possible about the habitat
specificity and life cycle...
Proban, Famphur and Tiguvon were administered intravenously,
subcutaneously, and orally at varying concentrations to 101 female
rabbits. The cholinesterase (ChE) activity levels of both plasma and
red blood cells were tested, as was tick and mosquito ChE, at various
times before and after dosage. The determinations measured the
inhibition of...
