Total yield for the treatment with 150 pounds per acre of urea fertilizer was similar to that produced with vetches, chicken manures and bloodmeal
, suggesting that soil nitrogen availability was a primary factor in increasing potato yield (table 4).
Resistance of Phlebotomus papatasi to infection with Leishmania donovani is modulated by components of the infective bloodmeal
Based on an estimated bloodmeal
volume of 5 mL/mosquito, the average virus dose ingested by mosquitoes feeding on this animal was 2.3 PFU.
We manured and limed our field a couple of months before planting, broadcast an all purpose organic fertilizer at planting time, then side-dressed with bloodmeal
, fish emulsion and kelp at the knee high stage.
Evaluation of potential West Nile virus vectors in Volgograd region, Russia, 2003 (Diptera: Culicidae): species composition, bloodmeal
host utilization, and virus infection rates of mosquitoes.
source identification was attempted on 399 host-seeking I.
Identification of host bloodmeal
source and Borrelia burgdorferi sensu lato in field-collected Ixodes ricinus ticks in Chaumont (Switzerland).
sources of Aedes triseriatus and Aedes vexans in a southern Wisconsin forest endemic for La Crosse encephalitis virus.
Anecdotally, the armadillo population increased substantially in the months after Hurricane Katrina, and one can speculate that these hosts supported a larger bug population, who later sought other bloodmeal
sources as the armadillo population returned to prestorm levels.
Not only do noninfected ticks that feed on these mammals fail to acquire spirochetes, but also infected ticks lose their infection during the course of such a bloodmeal
To determine whether saliva collection accurately approximates the amount of VEEV transmitted during a mosquito bloodmeal
, we quantified virus from saliva collected in vitro and virus deposited at sites of in vivo blood feeding.
However, because of the study design, it was impossible to distinguish among 3 potential explanations for this effect: socioeconomic confounding, better nutritional status leading to decreased progression to kala-azar, and the role of bovines as a preferred sand fly bloodmeal
