Scale insect infestation threatens coconut industry in Isabela City

By Rene V. Carbayas

ISABELA CITY – Scale insect (Aspidiotus Destructor Signoret), a soft-bodied 5mm long fluid-feeding insect is invading the coconut plants and other palm and fruit trees in the city posing threat to farmers’ livelihood and the coconut industry.

Rudy B. Corsame, officer-in-charge of the Philippine Coconut Authority (PCA) in Isabela City revealed that as of July 15, 2013, some 15 barangays have been affected by the pests.

Hardest hit was Barangay Lanote with some 2,519 coconut trees affected, followed by Maligue, Cabunbata and Lumbang. 

PCA data showed that the 15 barangays have a total of 702,956 coconut trees and 5,975 of these were infested with the scale insect. The data also showed that the pest also attacks some 1,170 ornamental plants, 382 lanzones trees, and 21 trees of mango.

PCA fears that more trees are affected, as 11 other barangays, namely, Calvario, Tabiawan, Panunsulan, Begang, Busay, Binuangan, Sumagdang, Kumalarang, Kapayawan, Balatanay, and Makiri are affected.

The Regional Development Council in Region IX (RDC) also got alarmed at the infestation, knowing the magnitude of damage it caused to the coconut farmers of Batangas.

Regional Director Noemi B. Edaga of the Philippine Information Agency (PIA)-9 disclosed that the RDC had come up with a resolution asking the agency to help conduct a massive information campaign about this pest.

During the regional technical briefing conducted recently in Zamboanga City to PIA personnel by PCA and the Department of Agriculture (DA), Edaga explained that “a massive information drive requires some budget which the agency has no funds for the purpose.” Thus, she asked the PCA to fund the campaign. The PCA agreed to “study the matter.”

Moreover, PCA-IX has also presented its plans to address the situation. At its level, PCA field offices have already started to alert the coconut farmers about the infestation, especially in Isabela City and made initial documentation on the extent of the infestation in the region.

PCA-Isabela City had also gathered the barangay chairpersons and selected kagawads of the 15 barangays affected by the pest last Aug. 1 to formulate plans to address the problem and control the spread of infestation to other barangays and neighboring cities and provinces in the region. The barangay officials have decided to conduct awareness drive in every affected barangay.

Corsame said the insect is not a new pest specie attacking coconuts in the Philippines. He pointed out that there are many reasons why an outbreak of coconut scale insect occurred, and one of them is bad agricultural practices such as overuse or misuse of pesticides, particularly on the vegetables and fruit trees planted under coconut plants. “Pesticides also kill natural enemies and without them, insect pests are free to multiply without control,” he stressed.

“Although coconut is the preferred host of scale insects, it is also known to attack other perennial species including many species of fruit trees, such as avocado, breadfruit, mango, mangosteen, guava and papaya. (PIA9)
