Mediterranean Fruit Fly Analysis

The polyphagous tropical Mediterranean fruit fly (Ceratitis capitata Weid. (medfly)) was detected in California in 1975, and a large-scale detection/eradication campaign was begun in the absence of sound knowledge of the fly’s potential invasiveness and geographic distribution. Persistent measurable populations of the fly have not been found in California, but a scientific explanation for this … Continue reading Mediterranean Fruit Fly Analysis

Grape Agro-ecosystem Analysis-Glassy winged sharpshooter

The invasiveness of the polyphagous glassy-winged sharpshooter (Homalodisca vitripennis (Germar), GWSS) using the PBDM approach. GWSS is indigenous to the southeastern United States and northeastern Mexico, and extended its range into California USA in 1989. GWSS is a vector of the pathogenic bacterium, Xylella fastidiosa (Wells et al. 1987), which causes Pierce’s disease (PD) in … Continue reading Grape Agro-ecosystem Analysis-Glassy winged sharpshooter

Climate Change Effects on Olive Fly

Climate change is expected to alter the geographic distribution and abundance of many species. Here we examine the potential effects of climate warming on olive (Olea europaea) and olive fly (Bactrocera oleae) across the ecological zones of Arizona–California (AZ–CA) and Italy. A weather-driven physiologically-based demographicmodel was developed from the extensive literature and used to simulate … Continue reading Climate Change Effects on Olive Fly

Light Brown Apple Moth

The highly polyphagous light brown apple moth (LBAM) (Epiphyas postvittana (Walk.): Tortricidae) is indigenous to Australia and was first found in California in 2006.  It is currently found in 15 coastal counties in California, but nowhere has it reached outbreak status.  The USDA projects the geographic range of LBAM will include much of Arizona and … Continue reading Light Brown Apple Moth

European Grapevine Moth

The European grapevine moth (Lobesia botrana (Den. and Schiff.)) is the principal native pest of grape berries in Europe. It was found in Napa County, California in 2009 and has since spread to six additional counties suggesting it is well established. The goal of our study was to predict the potential geographic distribution and relative … Continue reading European Grapevine Moth
