Systematics and host associations of Ormyrus species (Hymenoptera: Chalcidoidea)

Creator:: Hanson, Paul E.
Abstract:: The genus Ormyrus has a worldwide distribution and comprises about sixty recognized species. The higher taxonomic relationships of the genus are uncertain, as evidenced by its placement in the families Ormyridae, Pteromalidae, or Torymidae. Here, the genus is described in detail and a preliminary catalog of the world species is...

Attractant, behavioral, and toxicological studies of Fannia canicularis L. (Diptera : Muscidae) in association with a mink fur farm

Creator:: Bland, Roger G.
Abstract:: 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...

Regional population dynamics of Argyrotaenia citrana in Northwest caneberry : phenology, overwintering survivorship, and movement as measured by pheromone traps and larval sampling

Creator:: Knight, Alan Lee
Abstract:: Developmental requirements were determined for both larva and pupa as 503 and 176 degree-days (dd) above a lower threshold of 5°C. Adult emergence occurred from 300 to 700 dd accumulated from January 1st. Cumulative male emergence preceded female's by 50 - 80 dd. A PETE phenology model modified to include...

The leafhopper genus Giprus (Homoptera:Cicadellidae)

Creator:: Sawbridge, Jane Rosamund
Abstract:: Members of the deltocephaline leafhopper genus Giprus Oman live on grasses, primarily in the desert-scrub, chaparral, and marine sand dune communities of western North America. Of 16 known species, 10 are undescribed. Recharacterization of the genus results in exclusion of Laevicephalus incongruus Oman. Differentiation of species is primarily dependent on...

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...
