A systematic study of the genus Phytocoris Fallén (Heteroptera:Miridae) in western North America

Creator:: Stonedahl, Gary Michael
Abstract:: The western Nearctic species of the genus Phytocoris Fallen were taxonomically revised. Over 15,000 specimens were examined. Information concerning host plant associations and distributions was compiled and summarized for use by future researchers. External morphological features and characters of the male genitalia were used to distinguish species. The genital tubercles...

Effectiveness of pheromone mating disruption for the ponderosa pine tip moth, Rhyacionia zozana (Kearfott) (Lepidoptera: Tortricidae), and its influence on the associated parasite complex

Creator:: Niwa, Christine Gail
Abstract:: The importance of pheromones in insect control relies both on their ability to reduce pest populations and on their relatively benign effects on nontarget organisms. This study was conducted to test the effectiveness of a pheromone application for mating disruption of the ponderosa pine tip moth, Rhyacionia zozana (Kearfott), and...

Certain factors affecting colonization of Ponderosa pine by Ips confusus (Leconte) (Coleoptera : Scolytidae)

Creator:: Pitman, Gary Boyd
Abstract:: The purpose of this study was to study in some detail host factors which influence the population dynamics of bark beetle. The dissertation objectives were to ascertain the applicability of utilizing osmotic pressure values and relative turgidity values of phloem tissue as indicators which reflect upon the physiological profile of...

Diurnal and seasonal flight patterns of bark beetles (Coleoptera : Scolytidae) associated with Douglas-fir forests of western Oregon

Creator:: Daterman, Gary E.
Abstract:: The study was undertaken to determine the seasonal and diurnal flight patterns of scolytid beetles inhabiting a second growth forest of Douglas-fir (Pseudotsuga menziesii (Mirb.)Franco) in western Oregon. Air temperatures, relative humidity, light intensity, and wind velocities were recorded for evaluation of their influence on flight activity. The insects were...

Reproductive biology of the European pine shoot moth Rhyacionia buoliana (Schiffermüller) (Lepidoptera : Olethreutidae), with special reference to mating behavior, sex attraction, and fecundity

Creator:: Daterman, Gary E.
Abstract:: Major objectives of the study involved development of a laboratory procedure to obtain mating, determining characteristics of female sex attraction, and determination of the effects of temperature and humidity on mating and fecundity. The second of two methods devised to obtain mating, "the vertical airflow technique," was convenient to employ...

Sound production in Leperisinus oregonous Blackman and L. californicus Swaine (Coleoptera:Scolytidae)

Creator:: Vernoff, Suellen
Abstract:: Both Leperisinus oregonus and L. californicus are bark beetle species which emerge from Fraxinus latifolia brood logs as sexually immature adults and disperse to living ash. Occasional field observations suggest that, for overwintering and maturation feeding, L. oregonus enter trunks and branches, whereas L.; californicus enter twig crotches, buds and...

Salivation and engorgement parameters of sucking insect vectors : implications in pathogen transmission

Creator:: Shieh, Jong-neng
Abstract:: The probing behavior and feeding activity of green peach aphid, Myzus persicae Sulzer, on Bacillus thuringiensis ssp. tenebrionis- transgenic potatoes, insecticide treated potatoes, and host plants with different preference were electronically monitored. I found that first, transgenic potatoes had no effect on green peach aphid probing suggesting that transmission of...
