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...

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...

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...

Epidemiological implications of sporozoite aggregation in malaria vectors

Creator:: Li, Xiaohong, 1963-
Abstract:: This study describes and quantifies some microprocesses of malaria transmission including blood vessel location by Anopheles stephensi and sporozoites delivery of An. stephensi infected by Plasmodium berghei. The study models the effects of malaria parasite-induced changes in probing behavior and mosquito mortality on disease transmisson. Finally, host, vector, and parasitological...

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...

Interactions of Amphorophora agathonica Hottes with raspberry viruses and resistant red and black raspberry

Creator:: Lightle, Danielle
Abstract:: In recent years, red raspberry production in Washington and British Columbia has been severely limited by a newly emerged virus complex that causes symptoms of crumbly fruit. The complex is comprised of three viruses: Raspberry bushy dwarf virus (RBDV), Raspberry leaf mottle virus (RLMV) and Raspberry latent virus (RpLV). Both...
