1982
Mohammad Basri bin Wahid | Abdul Halim bin Haji Mohammad Hassan
With the introduction of the weevil, Elaeidobius kamerunicus into Malaysia in late 1981, two surveys, one covering oil palm estates and schemes, and the other covering palm oil mills were conducted between April and September 1982. The aim of the former was primarily to determine the rate of distribution of the weevil and its initial effects. While the aim of the latter was to determine the nature and extent of problems faced by oil palm mills due to weevil-pollinated bunches. The results of the first survey showed that the introduction of the weevil started in January 1981 reaching its peak in November 1981. By February 1982 all estates had introduced the weevil. Most estates bought the weevil for release. The results of the second survey showed that serious problems at the mills occur at the stripping and nut-cracking stations. Problems at the press station, depericarper station and cyclone separation are relatively minor. Mill problems were first reported in January 1982, with the peak number of reports occurring in July 1982. Most mills reported a decline in oil extraction rates while only a few reported an increase.
