The Red Palm Weevil, Rhynchophorus ferrugineus: Current Issues and Challenges in Malaysia

The red palm weevil (RPW), Rhynchophorus ferrugineus is an economically important pest of palms in many parts of the world. The weevil was first reported in the east coast of Peninsular Malaysia in the early 2007, where it is now causing severe damage to coconut palms. However, in 2016, the RPW has been reported in five states – Perlis, Kedah, Pulau Pinang, Terengganu and Kelantan, with the latter being the worst-hit. The weevil has also been found in oil palm plantations of FELDA and FELCRA by using pheromone trapping, but so far there is no evidence of the oil palm trees being affected. Current method to manage the RPW in Malaysia is largely based on pheromone mass trapping. However, it is still not an effective way to reduce the infestation of the RPW as the weevil population keeps increasing drastically. Thus, urgent action with special management considerations should be taken in order to reduce the problem. Here we report the identification, life cycle, symptoms of infestation, current management tactics for the RPW, and the potential threat of RPW to oil palm industry.

Kumbang merah palma (RPW), Rhynchophorus ferrugineus adalah merupakan perosak penting pokok palma di banyak kawasan di dunia. Kehadiran kumbang ini pertama kali dilaporkan di pantai timur Semenanjung Malaysia pada awal tahun 2007, di mana kini ianya menyebabkan kerosakan yang teruk kepada pokok kelapa. Walau bagaimanapun, pada 2016, RPW telah dilaporkan melanda lima negeri – Perlis, Kedah, Pulau Pinang, Terengganu dan Kelantan, negeri terakhir yang paling teruk terkesan. Kumbang ini juga telah ditemui di ladang sawit FELDA dan FELCRA dengan menggunakan perangkap feromon, tetapi setakat ini tiada bukti menunjukkan serangan telah berlaku ke atas pokok sawit. Kaedah semasa untuk menguruskan RPW di Malaysia adalah sebahagian besarnya menggunakan perangkap feromon. Walau bagaimanapun, kaedah ini bukanlah satu kaedah yang efektif untuk mengurangkan infestasi RPW kerana populasi kumbang didapati telah bertambah secara drastik. Oleh itu, tindakan segera perlu dilakukan untuk mengurangkan masalah ini dengan mengambilkira pengurusan yang khusus. Penulisan berkaitan RPW ini merangkumi keterangan identiti, kitaran hidup, simptom serangan, taktik pengurusan semasa dan juga potensi ancamannya terhadap industri sawit.

Evaluation of Entomopathogenic Fungi and Chemical to Control Termite, Coptotermes curvignathus on Mature Oil Palm and Supply Seedlings on Peat

The use of chemical insecticide, fipronil and two entomotahogenic fungi, Beauveria bassiana and Metarhizium major on termite control was evaluated. The experiment was conducted in high termite infested field with 10 year-old palm and young supply seedlings of six months after planting. Treatment on infested mature palm was conducted by spraying of product solution on […]

The Impact of El Niño and La Niña on Malaysian Palm Oil Industry

El Niño and La Niña are two complex weather patterns that result from variations in the ocean temperatures of the equatorial Pacific. Being close to the equatorial Pacific, the occurrence of the socalled El Niño-Southern Oscillation (ENSO) events has a notable impact on Malaysian weather. The wind circulation of the ENSO influences the precipitation in […]
