Abstract
A survey was conducted in the East Siang district of Arunachal Pradesh, India during the period 2013-2014 for the identification of Loranthus species infesting the Khasi mandarin orchards in this region. Study on its habit, mode of seed dispersion, host plants, its life cycle and its management in different sites of East Siang district was conducted. It is identified that the Loranthus species as Helixanthera ligustrina (Loranthus ligustrinus) which flowers during the month of April - May and the seed dispersal is mainly done by two birds viz., Plain flowerpecker and Fire breasted flowerpecker in June-July period. The study also revealed that it is one of the main problems causing Khasi mandarin decline by lowering down its yield and productivity and finally killed the plant after 4-5 years of infestation. This parasitic weed is slowly spreading to other nearby orchards and needs emergency attention for the citrus grower.
