MANILA, Philippines — The Taal Volcano eruption will leave a long-term effect on the environment biodiversity particularly in places that were reached by the ashfall.

According to the Bureau of Plant Industry (BPI), a plant’s growth depends on the survival or extinction of insects affected by the ashfall.

The BPI said a declining number of insects will also result in declining of plant pollinators.

Insects serve as pollinators that help plants reproduce.

“Basta walang pollinator na nagpopollinate walang mabubuong bunga so kung walang bees walang kape, walang prutas or others wala,” says BPI Crop Management Bureau Chief Wilma Cuaterno.

A declining number of insects can also cause a decrease in the number of decomposers that help decompose leaves that have fallen from branches or animals that perish.

The extinction of some species of insects would also result in the breaking of the food chain and cause ecological imbalance.

The BPI reiterates that insects, especially the so-called friendly insects, play a vital role in the lives of people.

BPI Entomologist Nestor Rivera said the effect of constant disturbance on insects due to the volcanic eruption may cause them to desert their breeding spot.
“Maghahanap sila ng pagkain para sa kanila. Magma-migrate talaga sila kasi kung wala nang kakaining halaman, [maghahanap] sila ng mga halaman para kainin para mabuhay sila,” he said. — (from the report of Dante Amento) /mbmf
