Description
Summary:The response of different plant species on some biological parameters of cotton mealybug and of its predator Coccinella septempunctata was investigated. All the tested plant species affected the studied biological parameters of cotton mealybug and C. septempunctata significantly. Maximum mortality in 1st instar nymphs (70-90%) was induced by rose (Rosa indica), jatropha (Jatropha curcus), mango (Mangifera indica), ashoke plant (Saraca indica), niazboo (Ocimum basilicum) and bouginvilla (Bougainvillea spp); in 2nd instar nymphs (50 to 70%), by rose, jatropha, mango, niazboo and Ficus sp., and in 3rd instar nymphs (40-50%) by ficus, rose, jatropha and bakain. The nymphal duration was prolonged by 20-23 days, when nymphs were fed on rose, jatropha, mango, ashoke plant, niazboo, Ficus and bakain, the same was shortened (16-17 days), when nymphs were fed on peeple, gardenia, shesham, Janem, vincarosa, cotton, shoeflower and silvery.
