hama pengerat sawit

Class: Serangga
Common Name: hama pengerat sawit
Scientific Name: Rhynchophorus Ferrugineus
Potential Host:

Palms

Symptoms:

Damage to invaded trees remain invisible long after infestation. By the time the first symptoms appear, the larvae population inside the trunk had months to develop. Many times, the damage is so severe the tree will die, making any actions irrelevant.

Sometimes, early warning signs appear in the form of yellowing and wilting on the crown and upper leaves. In cities and populated areas, there are risks of collateral damage from collapsing trees.

The adult beetle is large and red colored. The spread of palm weevil is due to the lack of early-detection methods in large parts of the world, the importation of infested palms, and the movement of palms and offshoots from contaminated to non-infested areas.

Who Am I?

Palm weevil is an invasive species of beetle that poses a serious threat to palms trees; it is considered to be the world’s most threatening pest to palms. Adult females are capable of flying long distances non-stop. A female can lay 250-300 eggs in her lifetime on cut or wounded palm-tree tissue. Palm weevil has the ability to knock down large palm trees that were completely healthy 6 months prior.

Control Measures

Tanaman atau bibit yang tahan terhadap penyakit merupakan syarat penting dalam budidaya.

Hindari pemangkasan yang dilakukan secara besar

Alat pemantauan hama (perangkap) sangat penting untuk mengetahui sebaran populasi dari hama.

Teknik kontrol dapat berubah berdasarkan varietas dari sawit.

Serangan kumbang pada umumnya pada bagian atas tanaman dan menyerang pada bagian daun yang terbuka.

Siapkan larutan sebanya 10-20 liter air per pohon dan tambahkan 25 ccimidacloprid (350 gr/L), dan 30 cccypermethrin (100 gr/L) dan 0.2 %tebuconzole (250 gr/L). kemudian semprotkan kebagian mahkota tanaman dengan durasi aplikasi 3 bulan sekali. (metode ini dilakukan untuk pencegahan dan pengendalian)

Untuk irigasi tanaman, direkomendasikan untuk menggunakan metode yang sama melalui sistem irigasi.

Aplikasi dilakukan di bagian bawah tanaman dimana menghubungkan antar cabang, hal ini dikarenakan serangan kumbang lebih banyak di area tersebut.

Caution and careful notice should be taken when using any plant protection products (insecticides, fungicides, and herbicides). It is the grower’s sole responsibility to keep track of the legal uses and permissions with respect to the laws in their country and destination markets. Always read the instructions written on labels, and in a case of contradiction, work in accordance to the product label. Keep in mind that information written on the label usually applies to local markets. Pest control products intended for organic farming are generally considered to be less effective in comparison to conventional products. When dealing with organic, biologic, and to some extent a small number of conventional chemical products, a complete eradication of a pest or disease will often require several iterations of a specific treatment or combination of treatments.
