ABSTRACT: The coconut eriophyid mite was reported to cause damage in homestead coconut in southern region of Bangladesh. The study was conducted during the month of February to May 2016 and 2017 in selected places of six districts in southern region to documents the infestation levels of mite A. guerreronis Keirfer on coconuts. The infestation of eriophyid mites on the basis of percent plant infestation on coconut was more in Barisal and was ranged between 72.94% (Lakutia) to 91.44% (Bakergonj). But the lowest in Gotkhali, 65.77 of Barguna district during the year 2015-2016. During the year 2016-2017 the highest infestation was found in Pirozpur (Namazpur, 92.58%)) and the lowest infestation was in Barisal (Sikerpur, 79.60). However, the pooled mean of infestation levels of both years during 2015-2016 and 2016-2017 were more in Barisal and Pirozpur districts (90.34%).The mean percent coconut infestation level of eriophyid mites on the basis of district during the years 2015-2016 and 2016-2017 was the highest in Pirozpur (87.42%) followed by Bhola (86.76%), Jhalokati (86.44%), Patuakhali (86.33%), Barisal district (83.94%) and the lowest in Barguna (80.92%).
