Coconut Worms: A Threat to Coconut Trees
The larvae of the coconut worm (Rhynchophorus ferrugineus) emerge from eggs laid in holes made by rhinoceros beetles (Dynastinae). They target the young parts of coconut trees, damaging the sprouts and eventually leading to the deterioration of the trees.
These worms pose a significant threat to coconut production, with the potential to devastate vast areas of coconut plantations annually.
Legal Restrictions on Coconut Worms
Due to their harmful impact, the breeding and sale of coconut worms are prohibited and heavily regulated. The 2022 Decree 07 outlines that anyone involved in breeding, distributing, or trading these pests could be fined between VND 3-12 million.
A notable case reported in July 2016 involved Pham The Hien, who faced a VND 6 million fine from the Ben Tre Department of Agriculture and Rural Development for selling coconut worms at his food garden in My Thanh An commune. Hien stated he obtained them from locals and was selling them for VND 10,000 each.
Coconut Worms as Local Delicacy
In the Mekong Delta, coconut worms are viewed as a local delicacy, popular with both residents and visitors.
Hien was required to agree not to sell coconut worms again, marking a first in Ben Tre for such enforcement under the laws governing plant protection and quarantine.
Ben Tre is known for having Vietnam’s largest area of coconut cultivation, spanning 67,000 hectares. In a move to shield coconut trees from harm, the provincial authorities issued a directive banning the breeding and distribution of these worms.
Despite the clear danger, some residents continue to breed coconut worms, and certain restaurants still serve dishes featuring this pest as a premium product.
The Risk and Reality of Breeding Coconut Worms
Residents of Ben Tre understand the rapid destruction coconut worms can cause to gardens. Yet, tempted by the high prices they fetch in restaurants, many ignore the law and secretly cultivate them.
Coconut worms are typically raised in plastic barrels where they consume coconut stems and leaves. Distinguishing between wild and farmed coconut worms can be challenging, as they thrive in similar conditions and feed on the same materials. Fresh coconut worms are sold between VND 3,000-6,000 each.
