abstract
The mountainous states of India and neighboring countries Nepal, Tibet and Bhutan assist large habitats for diverse orchid species. Present study revealed the orchid species in natural habitat and its hybrids growing in the farms under controlled conditions suffered from various biotic stresses. This species of scale insect reported as orchid pest in Indian subcontinent long back in the 1950s but no published records have documented L. pinnaeformis on orchids in the country so far. We report results of a survey conducted in five different locations of North East India including own institute farm (Pakyong, Sikkim) from 2012 to 2013. We infer that orchid scale, Lepidosaphes pinnaeformis Bouche (Hemiptera: Diaspididae), is an emerging pest causing medium to heavy damage to orchids round the year at different altitudinal range of the territory.
