A field experiment on the effect of farmscaping on the seasonal incidence of major insect pests of tomato was carried out during August to November, 2012 at the Horticulture Farm, Rajasthan College of Agriculture, Udaipur (Rajasthan). The pest status was evaluated on tomato cultivated as sole crop and with marigold under stacked and unstacked treatments. The population of the sucking insect pests of tomato was significantly the lowest when marigold was used as a farmscape crop with tomato, especially when unstacked [aphids (6.51), jassids (5.96) and whiteflies (5.16)]. Sole tomato, stacked or unstacked, significantly harboured more sucking insect pests than when tomato was farmscaped with marigold. Stacked tomato cultivated with marigold was more effective against the tomato fruit borer infestation, as evident by the lowest number of damaged fruits (1.60 per plant) with minimum loss in fruit weight of 51.84g leading to an increase in yield of 84 per cent; while unstacked tomato sole had the highest numbers of damaged fruits (10.00 per plant) with a corresponding loss in fruit weight of 324g.
