In India, tomato is both a high value crop, often exported to the Middle East, and an important subsistence vegetable grown mainly by women. Tomato leaf curl virus (ToLCV) and its whitefly vector, Bemisia tabaci (Genn.), are two of the most serious constraints to tomato production in India. When populations of B. tabaci are high, 90 to 100 percent of plants can become infected, resulting in a yield loss of 40 to 100 percent. Farmers consider these problems to be of burning importance and they have attempted to manage them with the only tool available to them. This tool is the intensive, widespread and increasingly unsuccessful use of insecticides in attempts to control B. tabaci and ToLCV, with associated risks both to their health and the environment. Development, promotion and uptake of IPM technologies to combat tomato leaf curl virus (ToLCV) and its whitefly vector, Bemisia tabaci (including open pollinated tomato varieties and hybrids resistant to all strains of the virus including those transmitted by the B biotype of B. tabaci), are two of the most serious constraints to tomato production in India,
