Next few months are critical for the recovery. Bio pesticides can tackle the issue.
Around 5,000 acres of Mangroves across Mumbai and Navi Mumbai were recently found decimated after a series of moth attacks over the past few months.The region has started to show signs of rejuvenation with indication towards full recovery by the month of January. The problem can be tacked with use of botanical bio pesticides to fight the hybladea puera moth.
Moth attack destroyed around 90% of the mangroves
The last few weeks witnessed the destruction of 90 percent of the mangroves in Mumbai and Navi Mumbai following the repeated attacks by the hyblaea puera moth (teak defoliator). According to the officials, they had never seen a moth attack in this capacity with the biggest challenge of spraying pesticides over such a large area.
The signs of rejuvenation can be seen in all dried up areas but experts feel it is too early to call it a comeback. The fisherman in the area is optimistic with the development of green patches and hopes to find a solution to combat pest attacks. In the aspect of environment, the destruction of mangroves across poses a risk to various other forms of life, including fishes, insects and thousands of flamingos.
Biopesticides can be used to tackle the problem
The Institute of Wood Science and Technology under the Indian Council of Forestry and Research published a detailed study on the problem, highlighting that 20 pests causing the defoliation and "terminal shoot destruction" in mangroves can be tackled by the use of botanical biopesticides. The challenge is to spray pesticide over such large areas in Mumbai and Navi Mumbai.
