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...
The carboxylesterases of three species of diptera, the flesh
fly (Sarcophaga bullata, Park.), the black blow fly (Phormia regina,
Meig.), and the house fly (Musca domestica, L.) were compared in relation
to hydrolytic activity against three substrates, response to
inhibition and induction, isozyme composition, and age-dependent
variation in activity. Similar...
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,...
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...
