Allogrooming behavior of European honey bees Apis melliferal L.

Creator:: Kuswadi, Achmad Nasroh
Abstract:: Workers in colonies of European honey bees Apis mellifera L. clean their nestmate's body by allogrooming behavior. This behavior may be initiated by either grooming dancers or by the allogroomers themselves. The first occurs less frequently (ca. 17 %) than the later (83 %). By using the inner edge of...

Biology of the two external Acarapis species of honey bees : Acarapis dorsalis Morgenthaler and Acarapis externus Morgenthaler (Acari: Tarsonemidae)

Creator:: Ibay, Lilia Armendez
Abstract:: The biology of the two external Acarapis mites of honey bees, Acarapis dorsalis Morgenthaler and Acarapis externus Morgenthaler was studied. It was observed that both Acarapis species have similar developmental period (8-9 days) with males emerging earlier than females. Mite load and infestation rate of A. dorsalis decreased as bees...

Aspects of the bionomics of the parasitic honey bee brood mite, Varroa jacobsoni Oudemans

Creator:: Principal de D'Aubeterre, Judith
Abstract:: Aspects concerning the bionomics of the parasitic honey bee brood mite, Varroa jacobsoni Oudemans were investigated. Mite mortality is great during the winter season when the host colony is not rearing brood, appearing to be independent of the mortality of its host. In winter period, no significant association between the...

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...

Biology and management of the obliquebanded leafroller, Choristoneura rosaceana (Harris) (Lepidoptera: Tortricidae), in sweet cherry

Creator:: Omeg, Michael Kent
Abstract:: The seasonal biology of the obliquebanded leafroller, Choristoneura rosaceana (Harris), was studied to improve its management in Mid-Columbia area sweet cherry orchards. Overwintering OBLR larvae began to emerge from hibernacula at bud stage 2 (side green). Most overwintering larvae emerged from hibernacula within three weeks of first bud swell and...

A revision of the black grass bug genus Irbisia Reuter (Heteroptera:Miridae)

Creator:: Schwartz, Michael David
Abstract:: The black grass bug genus Irbisia Reuter was revised. Over 18,000 specimens were examined and information concerning the biology, host plant and distributional relationships of the species was compiled. In addition to external characters, the male claspers and vesica, and the female dorsal libiate plate of the bursa copulatrix and...

The effect of photoperiod and temperature on ovarian development and fat production in Culex peus Speiser (Diptera:Culicidae)

Creator:: Skultab, Seeviga
Abstract:: The effect of photoperiod and temperature on ovarian follicle development and fat production was studied in a colonized population of CuZex peus Speiser from Philomath, Oregon. Females were subjected to simulated fall conditions of photoperiod and temperature. Under a combination of short photoperiod and low temperature, there were various effects...

Pheromone-mediated behavior of adult Douglas-fir tussock moths, Orgyia pseudotsugata (McD.) (Lepidoptera: Lymantriidae)

Creator:: Swaby, James Archie
Abstract:: The sinuous flight behavior of male Douglas-fir tussock moths, Orgyia pseudotsugata, (McD.), is characterized by positive anemotaxis and positive chemoklinotaxis and varies depending on distance from the pheromone source, population density, and time of day. Visual cues play a minor role in close-range orientation to a pheromone source, but males...

Studies on the flight behavior of Ips confusus (Lec.) (Coleoptera : Scolytidae) in response to attractants

Creator:: Gara, R. I. (Robert Imre), 1931-
Abstract:: The flight behavior of Ips confusus (Lec.) was primarily studied under field conditions, but augmented with complementary laboratory studies whenever feasible. The experiments were mostly conducted in areas of endemic population levels, but also under epidemic and prairie conditions. The techniques and devices used in marking, releasing, attracting, and trapping...
