Some Aspects of the Ecology of Elaeidobius Kamerunicus Faust, The Pollinating Weevil of Oil Palm, With Emphasis on Developing Sampling Techniques

Some aspects of the ecology of the pollinating weevil of oil palm, Elaeidobius kamerunicus Faust - an exotic insect to Malaysia imported from Cameroon, West Africa, three years ago - were studied in 1983 and 1984. In particular, sampling techniques for estimating the weevil population were devel...
