Popis:	Production of tomato is hampered by many diseases in the field. Tomato yellow leaf curl virus (TYLCV) is the major limiting factor for tomato cultivation all over the world. Its incidence is higher in tropical and subtropical areas mainly because of higher activities of whitefly (Bemisia tabaci) (Kung. 1999: Lapidot et al., 2001). It is also an important disease of tomato in Bangladesh (Rashid et al., 2001). Application of pesticides is generally suggested for the management of virus diseases in Bangladesh, but in most cases it is ineffective. Therefore, vigorous search for finding other effective alternatives is necessary. Some researchers found that trap crops may reduce incidence of TYLCV and other viruses due to delay in initial infection (Al-Musa, 1982: El-serwiy et al., 1987; Ahmed et al., 1996). But there is no report on the effect of trap crop on virus diseases prevalent in Bangladesh. The present experiment was conducted to find out the efficacy of brinjal, cucumber and okra as trap crops against whitefly to manage TYLCV on tomato.
