Abstract:
The present study was conducted in all over Bangladesh during the period from
November, 2015 to May, 2016 to know distribution, host preference, damage
severity, percent of infestation, infested plant part and percent of plant part
infestation and damage severity of mango mealybug. Survey was done at 26
districts and 87 upazilla in Bangladesh. Mango mealybug was recorded from 17
upazilla out of 87 upazilla in Bangladesh. Jackfruit was common host at all
locations followed by mango. Among all the host plant Mango and Jackfruit are
most preferable for mango mealybug. Comparatively higher infestation occurred
on fruit of jackfruit (about 86.72%) compared to inflorescence (about 73%) and
branch (about 78.3%). In, case of mango, more infestation occurred on
inflorescences (about 84.38%) than branch and fruit. High severity was observed
on fruit of jackfruit (about 86.72%) and inflorescence (about 84.38%) of mango
