Muga worms have been dying for last two decades due to air pollution from tea gardens (pesticides), brick factory, coke industry, cement factory and oil refineries also. Oil and and Natural Gas Commission (ONGC) has been carrying o their oil explorations near the farms with seismic survey. This process is followed to detect presence of crude with explosion. Thousands of Muga silk worms die every year due to vibration caused by the explosions. Such incidents are very common in Tinsukia, Dibrugarh, Sibsagar, Jorhat and Golaghat districts in upper Assam where oil companies like ONGC and Oil India Limited (OIL) have been carrying out oil productions for decades and the silk cultivation has been marginalized in these areas.
