Studies conducted with the adult western cherry fruit fly,
Rhagoletis indifferens Curran, revealed that successful oviposition
occurred in three distinct phases, the prepenetration phase, the
penetration phase and the postpenetration phase. During the
postpenetration phase which averaged 51 seconds (range 18 to 86), the
females dragged their ovipositor over the...
Adult emergence studies conducted with Rhagoletis indifferens
Curran reveal that diapause development in this insect is completed
most rapidly at approximately 3°C. These results coupled with those
reported by Brown (1978) confirm that chilling at 3°C. for ca. 200 days
is best when high percent emergence, good synchrony of emergence,...
Air temperatures and soil temperatures at the surface, two inches,
and four inches under a grass cover were recorded over a 93 day period.
These data were used along with other temperature data from bare soil
in the construction of three sets of models for the prediction of
maximum and...
Eight strains of housefly, Musca domestica Linn., from two
laboratories were intercrossed to form a stock population. Virgin males and females from the stock were collected, and nine sets, each
consisting of twelve males mated to five females, were successively
done. Pupae weight, adult weight, emergence time and egg production...
Craneflies of the genus Lipsothrix inhabit decomposing wood in
streams. The life cycles and ecological relationships of L. nigrilinea
(Doane) and L. fenderi Alexander were investigated to determine how they
exploit and respond to the wood habitat and their role in degradation of
woody debris in western Oregon. Surveys of...
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...
A combination of genetical and biochemical methods were
utilized in investigating house fly resistance to naphthalene. The
inheritance of resistance was determined by crossing a naphthalene
resistant strain of Musca domestica L. with a susceptible mutant
marker strain. Biochemical comparisons were made on substrains
isolated from the progeny of these...
