Objectives
The overall objective of this study is to utilize silverleaf whitefly population data and tomato yellow leaf curl (TYLCV)
incidence and intensity information in GIS-based analyses to determine
environmental and cultural factors that affect distribution and spread
of both pests. The information will be used to prevent or
minimize the impacts of these pests by understanding the dynamics
involved with their movement. The specific objectives are to:
(1) Use commercial
scouting data in Florida to initiate the evaluation of various GIS
spatial analysis techniques to interpret TYLCV and silverleaf whitefly
movement trends in time.
(2) Collect additional TYLCV
incidence and severity data and silverleaf whitefly population data in
selected geographical areas of Puerto Rico and Florida for GIS evaluation to
determine additional data needs for improving trend analyses (i.e. more
detailed information about factors which my influence pest movement and
intensity such as neighboring fields and alternative plant hosts cultural
practices, temperature, wind direction and speed, etc.)
