Starvation Levels Affect Behaviors of Wild-Caught and Laboratory-Reared Oil Palm Pollinator Weevil, <i>Elaeidobius kamerunicus</i> (Coleoptera: Curculionidae)

| description | The oil palm pollinating weevil, <i>Elaeidobius kamerunicus</i> Faust (Coleoptera: Curculionidae) was first introduced into Malaysia from Cameroon as the main oil palm pollinator in 1981. Since then, oil palm pollination has improved and the need for assisted pollination has reduced. However, their pollinating behavior may be influenced by starvation, sexes and sources (wild-caught and lab-reared). A study to determine the effect of starvation level, sexes and sources of <i>E. kamerunicus</i> on their diurnal behavior was conducted utilizing two hours of direct observation between 1130 and 1330 h. The frequency and the time spent for several diurnal behaviors on oil palm flowers were recorded and evaluated. Starvation prevented the weevils from conducting the activities because they probably had to focus more on searching for food to gain energy to perform other behavior. Wild-caught and lab-reared <i>E. kamerunicus</i> differed in their size, while sexes of <i>E. kamerunicus</i> significantly affect the diurnal behavior. However, an in-depth study is needed to determine the relationship between the diurnal behavior of <i>E. kamerunicus</i> and oil palm production. |
