Caterpillar Outbreak Threatens North Bengal Tea Production
Imagine tiny caterpillars eating all the leaves on tea plants in North Bengal.
This is happening now, and it's called a looper caterpillar outbreak.
These pests are munching away and could cause a lot less tea to be made next year, about 10% less!
The problem is getting worse because the weather is changing, with rain coming at the wrong times and winters getting warmer.
Tea gardens use chemicals to kill the caterpillars, but the bugs are getting used to them.
Making tea is also getting more expensive, and the price of tea is not rising enough to cover it.
Experts are trying to find new ways to stop the caterpillars and get help from the government.
Looper caterpillar outbreak threatens tea production in North Bengal's Dooars region.
Tea planters anticipate a 10% drop in production for the 2025 season due to the infestation.
Climate change, erratic rainfall, and warmer winters exacerbate the looper caterpillar problem.
Pesticide resistance and rising costs compound the challenges for tea gardens.
Industry experts and associations are seeking solutions and government support.
