Elaeidobius kamerunicus Faust (Coleoptera: Curculionidae), the pollinating weevil, is the most efficient insect pollinator of oil palm, Elaeis guineensis. The pollination of the oil palm is assured mainly by the insects. The most effective are Elaeidobius kamerunicus and Elaeidobius plagiatus. Declining.

BoxKuala Lumpur, Malaysia. The correlation between weevil activity and weather parameters viz. A less efficient existing pollinator, Thrips hawaiiensis was not apparently displaced by E.

Elaeidobius kamerunicus

Applying fertilizers did not reduce bunch numbers. Freed of competition with other species of Elaeidobius, it breeds in all parts of the male inflorescence and is equally common in all rainfall zones. The change in numbers of fruit set affects the harvesting standards used for optimizing oil production, as these are based on numbers kamerunicuss loose fruits. Publication Policies and Ethics. The population density of E.

Close Find out more. It is estimated that the yield at Bukit Sentang Estate will return to the level of the pre-weevil period Taniputra, During the period after the introduction of the weevil into Malaysia, there was no significant change on bunch parameters, with one exception: The presence of larvae appeared to attract rats.


M of the day and the peak was observed during Although wind, plus assisted pollination was more efficient than wind plus weevil pollination No part of this publication may be reproduced in any form or any means without the written permission elaeodobius MPOB.

The activities of pollinators on anthesising female inflorescences were measured by pan-trapping. Agri and Aquaculture Journals Dr. Role and effectiveness of Elaeidobius kamerunicus, Thrips hawaiiensis and Pyroderces sp. This is normally carried out by hand. Two liberations of E. However, during their first few years, young oil palms produce primarily female flowers, only producing sufficient male flowers for the establishment and effective activity of pollination insects from the age of months.

No weevils were found developing during May 4 th week to June 2 nd week. October, November and December months were found to be ideal for the development of the weevil. The average viability of the pollen load was Besides the low rate of fruit setting, sometimes lack of adequate pollination also results in bunch failure.


It appeared that the weevil did not change the monthly yield pattern. Improved set has caused the production of more but smaller fruitlets, but has affected oil yield per bunch very little.

CurculionidaeThrips hawaiiensis Thysanoptera and Pyroderces sp. Reports of successful establishment and enhanced yields are now being received from these countries Greathead, Control methods are not appropriate for E.

Average bunch weight increased The pollen carrying capacity of males was significantly greater than that of females, which was partially due to the greater surface area of males and especially the presence of pleural setae. Therefore, before this age, artificial pollination is required. The weevils were taken to Sabah in March,with even more impressive results. Areca catechu betelnut palm.

As a result of this introduction, average fruit set increased from Cookies on Plantwise Knowledge Bank Like most websites we use cookies.
