Abstract
Fruit flies are the main pest problem with guava production in Calvillo, mainly for quarantine restrictions that prevent guava fresh fruit exportation.
The Calvillo-Cañones is the most important guava producing region in Mexico and currently it is considered a low prevalence zone for fruit fly, a condition achieved as a result of a fruit fly management program that started in 1993. To support this program, a digital geodatabase system is being developed for the Calvillo region with cartographic and satellite images, topographic cartography at the 1:20,000 scale, geostatistical and climatic information, in combination with spatial and temporal fruit fly trapping information over the last five years.
The information was reviewed and validated in ArcGIS 9.1 followed by some preliminary analysis of fruit fly infestation and distribution.
Our preliminary results showed no relationship of fruit fly trapping with slope, altitude, orientation and landscape elements, suggesting that other factors such as pesticide applications and alternate hosts may be strongly involved.
Integrating fruit fly information with cartographic, topographic, socioeconomic and biological data can help to better understand fruit fly spatial and temporal dynamics for decision support management in the guava producing region of Calvillo.
