Research Emphasis, past and present
I joined TAES-Weslaco in 1998 as a Research Associate working with tachinids in sugarcane while completing my doctoral thesis. Since 2000, I have been working with insect vectors of Pierce’s disease of grapevine. I was originally assigned full time to the Cooperative Glassy-winged Sharpshooter Areawide Management Program, a USDA-APHIS program, and re-assigned in 2004 to the Texas Pierce’s Disease Research and Education Program, as well a multi-disciplinary and multi-institutional program funded by USDA-APHIS in Texas since 2003. The goal of this program is to reduce the losses due to Pierce’s disease in vineyards both in Texas and California.
Currently, my research activities focus on the development of management strategies against xylem sap-feeding Hemiptera responsible for Pierce’s disease of grapevine. My experience in both applied and basic research of insect populations provides me with the background to study the biology and ecology of the vectors with emphais on elucidation of the abiotic and biotic factors affecting population dynamics. Additionally, research during my career has provided me with field and laboratory experience in biological control of insect pests and insect rearing.
