A survey of alfalfa pollinators and polination in the San Joaquin Valley of California with emphasis on establishment of the alkali bee

Creator:: Torchio, Philip F.
Abstract:: The study involves the establishment, management, and behavioral observations of Nomia melanderi Cockerell and Megachile rotundata (Fabricius) in California, a survey of native bees within western Fresno County, a determination of selfing and/or parthenocarpy in two fields of alfalfa, and observations on the honeybee as an alfalfa pollinator. The alkali...

Use of petroleum oils to prevent spread of stylet-borne viruses by aphids

Creator:: Ascerno, Mark E.
Abstract:: The use of petroleum oil prevented, to varying degrees: the transmission of three stylet-borne viruses in three different crops. The use of oils resulted in a marked improvement in the number of lily bulbs harvested from treated plots as compared to the number of lily bulbs harvested from untreated plots....

Oil sprays to prevent the spread of bean yellow mosaic virus (BYMV) by aphids

Creator:: Vargas, Timothy Carl
Abstract:: The influence of oil sprays on the field spread of the aphid-borne bean yellow mosaic virus (BYMV) in bean was studied in 1972 and 1973. Oil sprays failed to significantly reduce virus spread in the 1972 BYMV experiment. However, the data did suggest that the efficiency of the oil sprays...

Temperature-dependent development of strawberry root weevil Otiorhynchus ovatus (L.)

Creator:: Umble, Jon R.
Abstract:: The temperature-dependent development of pupae and adults of strawberry root weevil (SRW) Otiorhynchus ovatus (L.) was studied in strawberry (Fragaria x ananassa Duch. var. 'Totem'). The development of pupae and adults was investigated at constant temperatures from 3-33°C at 3°C intervals. Major emphasis was on the development of a weighted...

Detection and characterization of resistance to pesticides in codling moth, Cydia pomonella L. from Oregon

Creator:: Arshad, Muhammad, 1958-
Abstract:: Toxicological studies were carried out to evaluate the susceptibility of codling moth, Cydia pomonella L. to different insecticides. Bioassay procedures for adults and larvae were standardized in terms of posttreatment holding and temperature, age and sex of insects, insecticide formulations and selection of a reference strain. This study detected a...

Influence of host anemia on blood-feeding rate and egg production of Aedes aegypti (L.) (Diptera : Culicidae)

Creator:: Shieh, Jong-Neng
Abstract:: I tested a theoretical model proposing that anemia favors transmission of blood-borne parasites to vectors by accelerating the blood-feeding rate. Using Aedes aegypti, the yellow fever mosquito, initially, I was not able to confirm this phenomenon either in an artificial or a live system; anemia did not correlate with blood-feeding...

An evaluation of factors influencing the management of Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae)

Creator:: Kepler, Ryan M.
Abstract:: The black vine weevil (BVW), Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae) is a persistent pest of nursery operations in the United States, feeding on over 140 species of plants. The goals of this research were to 1) assess the behavioral response of BVW to a commonly employed insecticide bifenthrin (Talstar 0.2G®)...

Transmission efficiency and life table parameters of western flower thrips, Frankliniella occidentalis (Pergande) exposed to tomato spotted wilt virus-impatiens serotype

Creator:: Sether, Diane M.
Abstract:: Peppermint, Mentha piperita 'Black Mitcham' was established as a host for tomato spotted wilt virus-impatiens serotype (TSWV-I). TSWV-I infection of peppermint, initially observed in a research greenhouse (Corvallis, OR), included stunting and downward curling of leaves accompanied by bronzing, and occasionally tip necrosis. Young leaves appeared either symptomless, deformed, or...
