Abstract
The natural pollinator of oil palm, Elaeidobius kamerunicus have been introduced into oil palm plantation in Malaysia to increase the oil palm yield. The application of biopesticide (Bacillus thuringiensis, Bt) to control the pest population is often regarded as harmless to a beneficial insect like pollinating weevil. However, it is not known if increased biopesticide dosage will negatively affect weevil. Therefore, this study was carried out to determine the survival rate of weevil when excess dosage of B. thuringiensis pesticide was applied. The result of this study found that increasing of B. thuringiensis biopesticide concentration on artificial diet from 94.27 ppm to 104715 ppm in dosage did not have adverse effect on E. kamerunicus survival. However, the survival rate of E. kamerunicus had significant dropped when B. thuringiensis biopesticide applied on the weevils' natural diet, oil palm male inflorescence. This indicates overdose application of B. thuringiensis biopesticide might have adverse effect on weevil population in the long term. Thus, pest management in oil palm plantation needs to review the effect of B. thuringiensis pesticide on pollinating weevil in order to sustain the oil palm industry.
