Abstract

25 plant species were screened for food preference of cotton mealybug, Phenacoccus solenopsis Tinsley, using a multi-choice experiment under laboratory conditions maintained at 25 ± 1ºC, 55 ± 5% relative humidity with a 16 h light: 8 h dark photoperiod. The proportion of 1st, 2nd and 3rd nymphal instars was recorded on 24 plant species at 2, 4, 8, 12 and 24 hours after release as compared with Chinese rose as control. The proportion of 1st and 3rd instar of P. solenopsis was maximum on cotton, but highest proportion of 2nd instar was recorded on weed plants including hazardani, qulfa and itsit as compared with control (Chinese rose). In contrast proportion of nymphal instars of P. solenopsis on other tested weeds i.e., loosen booti, tandla and krund.
