From August 1977 to March 1978, 2,132 coconuts were collected, 60.75% of which were infested with the insect, of these, 1,295 were infested and 381 had been abandoned by the insect. In the remaining coconuts 635 larvas, 42 prepupas, 213 pupas and 24 adults were found. Laboratory work showed the following death rates: larvas, 27.93%, prepupas and pupas, 0.90%; adults 5.51%.
