Biología del Comportamiento, Reproducción y Alimentación de Polinizadores de la Familia Curculionidae en Híbridos de Palma Aceitera (E. Oleifera. X E. Guineensis) en el Oriente Ecuatoriano

Abstract:

Oil palm hybrids appear as a solution to productivity and as an alternative to disease problems. Oil palms E. oleifera and E. guineesis and their interspecific hybrids OxG are monoecious; they have male and female inflorescences produced in alternating periods. For this reason, anemophily and entomophylly pollination are important in nature. However, these two pollination systems are not enough for commercial fruit set. So, assisted pollination by hand is used generating high production costs. This work bring foreward a study of the biology of native and exotic insect pollinators in oil palms in eastern Ecuador, as an option for improving crop productivity and as an alternative to reduction of cost production in the future. The results of this work shows the reduced level of attraction of species of pollinator insects by interspecific hybrid´s masculine and feminine inflorescences in oil palm plantation “Palmar del Rio”. The higher pollinator potential was seen in species as Elaedobius kamerunicus, Elaeidobius sp., Grasidius hybridus and Couturerius sp. Elaeidobius kamerunicus was the largest pollinator in numbers and the specie that carried a greater amount of pollen grains…
