Coconut bug injures the tender portion of young crazy and suck sap. Initially the damage appears as a three-cornered yellowish dark patch extending distally on the product surface from beneath the perianth. The injury ultimately leads to warting and long fissures on the nut surface. The development of nut is obviated and ultimately the usual breadth of the nut, covering, and kernel are shortened. The affected nuts create de-husking movement difficult and defeat fiber characteristic of the husks. Continuous devastation by the top part of an animate body mite fashioned the farmers from Bangladesh to oust their coconut cultivation accompanying other recipient crops by cutting unhappy the coconut covering huge areas. Considering the power of the problem, a study was administered in an ecosystem with the approaches for revival of coconut in Bangladesh through bug management. Different educational, chemical, botanical situations and combinations of those were executed on the marked palms as the control measures. The study regions covering around 696 hectares of land containing 551 households of eight (8) villages represented an environment unit. Coconut palms in the analysis area were counted as 4429 for the attack. There were six treatments in the study that were deploying on strategically selected 90 palms. During the whole study period, other palms of the field were treated accompanying 0.2% Propargite 57% EC in an interval of two months. After two age of intervention, each and every seed of fruit, vegetable of the palms of the study area raise without some sign of mite attack.
