Resources partitioning and different foraging behavior is the basis for the coexistence of Thrips hawaiiensis (Thysanoptera: Tripidae) and Elaeidobius kamerunicus (Coleoptera: Curculionidae) on oil palm (Elaeis guineensis Jacq) flower

  Indonesia is considered as main producer of oil palm. Oil palm production depends on the pollination process of its flowers. Observation on Indonesian local oil palm (Elaeis guineensis) plantation showed the coexistence between introduced pollinator, Elaeidobius kamerunicus, and native pollinator Thrips hawaiiensis. In order to find the factors responsible for this coexistence, observation...

Ecology and field biology of the sorghum chafer, Pachnoda interrupta (Olivier) (Coleoptera: Scarabaeidae) in Ethiopia

  Studies on sorghum chafer (Pachnoda interrupta) were conducted under field conditions for two consecutive years (2005 to 2006) to determine the biology and ecology of the beetle. On average, oviposition rate by a single female was 1.28 eggs per day over a period of 11 days. In general, eggs hatched within 4 to 22 days with a mean of 15.7 days, after which larval and pupal stages lasted a mean of 59.8 and 18.3...
