Abstract

A mealybug Paraputo odontomachi (Hemiptera: Pseudococcidae) and two species of ambrosia beetles, Amasa sp. (Coleoptera: Curculionidae: Scolytinae) and Crossotarsus sp. (Coleoptera: Curculionidae: Platypodinae) on clove trees were recorded for the first time in Minahasa, South Minahasa and South Bolaang Mongondow District, North Sulawesi Province. These polyphagous insects are known to live on several host plant species. The objective of this research is to identify the mealybugs species, and then beetles on clove to determine the type incidence and the effect of the pest attack on clove. Field observations showed that the three insects were found on clove trees in Minahasa. For the first time the assessment of pest infestation and percentage incidence (PI) were carried out in the clove plantations area of PT Kawanua Kahuripan Pantera in Lungkap and Kombot Villages, South Bolaang Mongondow District. P.odontomachi generally live around the base of roots and stems. The association between P. odontomachi with black ant (Dolichoderus thoracicus) broaden its distribution to the middle part of the tree. Ambrosia beetles, Amasa sp. damage the plants by bore holes on the stems and branches while Crossotarsus sp. only bore on the stems. Attacks by ambrosia beetles usually result in the death of stem and branch tissues; plants may exhibit dieback following the attacks. However, mass attacks of these beetles can lead to plant death.
