Tree bean (Parkia roxburghii) is an important leguminous cash crop in Mizoram and other North Eastern Region of India. However, its production is threatened by several abiotic and biotic factors, especially insects and diseases. Declined of tree bean was frequently observed and reported in all the districts of Mizoram since 90’s which caused serious setback for tree bean growers. However, there were no systematic studies or research conducted to assess the role of insect pests on declining tree bean in Mizoram. The present investigation was carried out in Thiltlang, Darzo, Tuipui D, Rotlang East and Hnahthial of the then Lunglei district, Sangau of Lawngtlai district and Siaha of Siaha district and on road side plantation of NH-54 from Aizawl to Tipa and World Bank road from Aizawl to Lunglei, Mizoram, India during October 2017 to October 2020. The present works was aimed at studying the insect species associated with this crop in the states and also constitute an important baseline data for the design and implementation of IPM strategies for Tree bean protection in Mizoram. The frequently associated insect with partial or complete declined of tree bean was identified as Ambrosia and bark beetles, Blepephaeus succinctor and Xystrocera globosa. In addition, Ambrosia beetles (Curculionidae, Scolytinae) and Blepephaeus succinctor (Coleoptera: Cerambycidae: Lamiinae) was reported for the first time attacking and causing Tree bean decline in Mizoram.
