New record of eriophyid mite, Cisaberoptis kenyae Keifer (Acari: Eriophyidae) on mango in Punjab.
A survey of mite pests on different fruit trees revealed an eriophyid mite, C. kenyae, on mango trees from an old orchard in Ludhiana, Punjab, India, in November 2002. However, the maximum mite population and its damage was observed during November-January. Infested leaves had a thin white papery layer on the dorsal surface, visible from a distance. An experiment was conducted under laboratory condition to investigate the effect of dipping mite-infested leaves in water for 5, 10, 20, 30 and 60 minutes and in 4 pesticides, i.e. Thiodan 35 EC (endosulfan), Tagthion 50 EC (malathion), Metasystox 25 EC (oxydemeton-methyl) and Kelthane 18.5 EC (dicofol) at 1 and 2 ml/litre for 10 seconds on the mortality of the mites. Dipping the mite-infested leaves in water from 5 to 60 minutes revealed negligible mortality of the mites. However, 24.76% mites were killed when the leaves were dipped in water for 60 minutes. All the pesticides were effective (<88% mortality) one day after treatment at 1 ml/litre. This is thought to be the first report of C. kenyae on mango in Punjab.
