A model of trophic evolutionary pathways

Creator:: Morris, A. Kimo
Abstract:: Calow (1983) realized that differences between parasites and their free-living relatives can be explained by the differences in nutrient richness. I propose a model that is based on Calow's idea which identifies the relative position of different trophic strategies (e.g. predation, grazing, parasitism and others) based on (1) the differences...

Stability and complexity : a reappraisal of the Competitive Exclusion Principle

Creator:: Duran, Israel N.
Abstract:: Elton (1927) realized that, intuitively at least, nature was complex and stable. And that the last property contributed to the first. This idea was challenged mathematically by Gardner and Ashby (1970) and May (1972), and in the years following various models have attempted to reconcile these opposing views. Unlike previous...

Evaluation of behavioral response of Aedes aegypti mosquitoes to repellents using a novel olfactometer

Creator:: Doğan, Elif Barc̦in
Abstract:: Mosquito-borne pathogens are the cause of important, often deadly diseases worldwide; and, use of repellents is one of the components of mosquito control programs. The most effective mosquito repellent is N,N-dimethyl-m-toluamide, known as DEET. Speculation on the adverse effects of DEET have been on the rise since the 1980s, and...

A lysozyme-like protein in the salivary glands of adult Aedes aegypti : functional and biochemical characteristics

Creator:: Pimentel, Gliceria Estandian, 1958-
Abstract:: This study investigated some functional and biochemical characteristics of a bacteriolytic protein in the salivary glands of adult Aedes aecupti. A method for the isolation of this protein from other mosquito salivary gland components is also described. Based on some of its biochemical properties, this bacteriolytic protein can be classified...

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...

Antibacterial activities in the salivary glands of female mosquitoes Aedes aegypti

Creator:: Deng, Lanqian
Abstract:: Antibacterial activities in the salivary glands of female mosquitoes Aedes aegypti were investigated in this study. The mean salivary bacteriolytic activity, during a period of 14-day of female mosquitoes exposed to five different concentrations of Gram-positive bacteria Micrococcus lysodeikticus in the sucrose meal, was detected by a lysoplate method. A...

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...

Post mortem interval and decomposition rates : biological observations and mathematical analysis

Creator:: England, David B.
Abstract:: Entomological evidence can be used for estimating post mortem interval (PMI). Decomposition studies have been conducted throughout the world and these studies have demonstrated that insect succession generally follows a similar pattern at a taxonomic level, specifically family, but varies at the genus and species levels with respect to geographic...

Mortality threshold for juvenile Chinook salmon (Oncorhynchus tshawytscha) in an epidemiological model of Ceratomyxa shasta

Creator:: Ray, R. Adam
Abstract:: The myxozoan parasite, Ceratomyxa shasta, is the most significant pathogen of juvenile Chinook salmon (Oncorhynchus tshawytscha) in the Klamath River, CA, USA. This parasite requires two hosts - a freshwater polychaete (Manayunkia speciosa) and a salmonid - to complete its life cycle. The complex life cycle and large geographic area...
