Improvement of biological control agents : laboratory selection for fast larval development in the convergent lady beetle, Hippodamia convergens guerin-Méneville (Coleoptera: Coccinellidae)

Creator:: Rodriguez-Saona, Cesar Ramiro
Abstract:: Hippodamia convergens Guerin-Meneville was selected for rapid development through five generations at four constant temperatures (18, 22, 26, and 30°C). Two levels of selection were used: intense and moderate. Differences in developmental rate, survivorship, live adult weight, aphid consumption, adult longevity, and fecundity were measured for both groups and an...

Aspects of the field and developmental biology of a Apanteles yakutatensis, a parasitoid of Autographa californica

Creator:: Madar, Robert John
Abstract:: Behavioral and ecological aspects of the field and developmental biology of Apanteles yakutatensis (Ashm.), a primary larval parasite of the alfalfa looper, Autographa californica (Speyer), were investigated in 1980 and 1981. Populations of A. yakutatensis were found in commercial peppermint, alfalfa and crimson clover fields involving two areas (Willamette Valley,...

Temperature-dependent development and field observations of some western Oregon coccinellids (Coleoptera: Coccinellidae)

Creator:: La Mana, Michael Louis
Abstract:: The recent colonization of Oregon by an exotic, intentionally introduced coccinellid, Harmonia axyridis, was the basis for lab and field research into lady beetle developmental biology and community composition. Harmonia axyridis was the dominant coccinellid in an arboreal habitat, and comprised over 70% of all lady beetles, and 82% of...

Distribution, phenology, and parasitism of the winter moth, (Operophtera brumata L.), in western Oregon

Creator:: Kimberling, Diana Nalani
Abstract:: An exotic pest of deciduous plants, Operophtera brumata (L.), was discovered in Portland, Oregon in 1978. O. brumata, the winter moth, is native to northern Africa and temperate Eurasia. Its range extends from Scandanavia, Britain, and France to Japan. It is also now well established on the North American continent...

Host exploitation by Dinocampus Coccinellae (Schrank) [Hymenoptera: Braconidae]

Creator:: Belnavis, Diane Lyn
Abstract:: Ecological relationships between D. coccinellae and its coccinellid hosts were examined in the Willamette Valley, Oregon, in 1982. The distribution and relative abundance of seven species of coccinellids from eight collecting sites were monitored to determine percent parasitism by D. coccinellae on a spatial and temporal basis. Host size and...

A three-trophic-level perspective on factors influencing herbivore abundance on collard

Creator:: McIver, James D.
Abstract:: The influence of natural enemies and plant apparency in determining the abundance of the cabbage aphid Brevicoryne brassicae L. and the imported cabbageworm Pieris rapae L. was examined on collards grown in a collard monoculture and in a collard-alfalfa biculture. This design was used to examine the factors affecting collardherbivore...

Biology and host relations of Meteorus comunis (Cresson)

Creator:: West, Kenneth John
Abstract:: Fifteen species of Noctuidae (Lepidoptera) were collected in alfalfa and peppermint in western Oregon. Seven of these species were hosts for the braconid parasitoid Meteorus communis. The most frequently parasitized (percent) species were Agrotis ipsilon (35.3), Dargida procincta (15.0), and Peridroma saucia (6.9). Other species parasitized were Autographa californica (3.8)...

The influence of light intensity on the phytochemistry of Chrysolepis chrysophylla (Fagaceae) and the relationship to the herbivory of Habrodais grunus herri (Lycaenidae)

Creator:: Bowden, Richard I.
Abstract:: Defensive chemical and nutritive quality of young leaves were measured for 72 individual trees of Chrysolepis [Castanopsis] chrysophylla in conjunction with light intensities of two different stand types and population numbers of Habrodais grunus herri in the Cascade mountains of Oregon. Leaves were collected in the spring and leaf characteristics...

Host suitability studies of Douglas-fir and white alder to the gypsy moth

Creator:: Joseph, Gladwin
Abstract:: Douglas-fir, Pseudotsuga menziesii and white alder, Alnus rhombifolia, species that are prevalent in the Pacific Northwest, were fed to larvae of the gypsy moth, Lymantria dispar L. Gypsy moth larvae from different familial lines (egg masses) from a single geographic population were evaluated on these hosts. The larvae were fed...

Ground dwelling beetles in early and late successional forests in the western Cascades of Oregon

Creator:: Heyborne, William H.
Abstract:: The effects of forest cutting on forested systems and the biotic components of those systems has been at the forefront of scientific research. The inventory and monitoring of biodiversity is one technique used for measuring the effects of forest management. Because bioinventory studies are expensive, indicator species are often sought...
