Invasive Species and Biosecurity: Cost of Monitoring and Controlling Mediterranean Fruit Flies in Florida AgEcon
Pierre, Raphael; Spreen, Thomas H.; Moss, Charles B..
The growing movement of people and goods that started in the closing years of the twentieth century has increased the possibility of the accidental or intentional introduction of biohazards that can affect agricultural production in the United States. This study examines the ex ante decision between the deployment of monitoring devices (traps) versus the use of countermeasures to control Mediterranean fruit flies in Florida. To examine this tradeoff, this study outlines a mathematical model to study the effectiveness of traps and the cost of treatment. The empirical results presented in this study indicate that additional parameterization efforts are needed.

Logistical estimation of the probability of mainstream market participation among small-scale livestock farmers: a case study of the Northern Cape province AgEcon
Uchezuba, I.D.; Moshabele, E.; Digopo, D..
Livestock farming significantly contributes to income generation and the improvement of the livelihoods of the rural poor in the Northern Cape. However, profitability and sustainability in the sector are constrained by low returns to investment due to a number of factors. The study investigates the factors influencing mainstream market participation among small-scale farmers in the five districts of the province. The main aim is to calculate the probability of small-scale farmers selling their livestock to more profitable mainstream markets, for example auction pens, against the odds of selling to informal speculators. A binary logistic regression model is applied to primary data collected from 60 sampled households in the districts of Kgalagadi, Pixley ka...
