| description | The oil palm pollinator, Elaeidobius kamerunicus is a weevil that belongs to Curculionidae It
has been found to have the highest capacity for efficient insect pollinator of oil palm. In order
to control the damage from reaching or nearing the economic threshold level (ETL), planters
are left with the option to use insecticides due to its fast action. Therefore, in this study the
efficacy of chlorantraniliprole, cypermethrin, flubendiamide, Bacillus thuringiensis, cnidiadin
and Isaria fumosorosea were tested on oil palm pollinator, E. kamerunicus. The pollens and
pollinators were collected from FELDA Besout, Perak, Malaysia. Adult of E. kamerunicus
were exposed to the insecticides residue and mortality was observed at 24, 48, 72 and 96 hours
after exposure. The percentage of mortality E. kamerunicus was recorded to determine the
insecticides efficacy. Mortality of E. kamerunicus was highest when exposed to cypermethrin
and chlorantraniliprole with 100% mortality of the population, followed by flubendiamide
(42%), B. thuringiensis (39%), cnidiadin (11%), I. fumosorosea (3%) and control (2%) at 96
hours post-exposure. Cypermethrin gave the shortest LT50 to killed E. kamerunicus at 17 hours,
followed by chlorantraniliprole, flubendiamide and B. thuringiensis which were 31, 136 and
137 hours, respectively. Whilst, lethality index of cypermethrin showed the highest value,
which was 91.50%, followed by chlorantraniliprole (76.50%), flubendiamide (27.25%), B.
thuringiensis (25.25%), cnidiadin (5.25%) and I. fumosorosea (1.75%). |
