Online published on 24 September, 2020. Abstract Eleven types of yellow sticky traps (15x30 cm) made up of different base and sticky materials were evaluated to determine their persistence and attractancy for greenhouse whitefly Trialeurodes vaporariorum (Westwood) in tomato under polyhouse during summer, rainy and winter cropping seasons. Base materials like yellow coloured thick paper and yellow painted galvanized iron sheet, and sticky materials like castor oil, mustard oil, linseed oil and white lithium grease were evaluated.The cumulative adult catches on traps evaluated remained significantly maximum (594.3 to 1118.0) during rainy season. Use of paper sheet smeared with different pasting materials resulted in significantly more trap catches, compared to the use of iron sheet. Irrespective of the base material, traps smeared with castor oil proved significantly superior followed by that of mustard oil, linseed oil and white lithium grease. The cost of traps ranged from Rs 165 to Rs 2025/cropping season of 140 days/250 m2 polyhouse; with the minimum and maximum being for the white lithium grease pasted on plastic sheet and commercial trap, respectively. The trap with castor oil pasted on paper sheet was good in efficacy but not cost effective. Trap with mustard oil pasted on paper sheet was one of the efficacious traps, and also cost effective.
