What is Tuta
The worst nightmare of any farmer. A moth belonging to the Gelechiidae family, also known as the tomato leaf miner or the South American Tomato Moth, this pest has a voracious appetite for destruction.
Why are they such a pest?
These moths, from larvae to adults feed relentlessly on every part of the plant, from leaves to stalks to raw and ripe fruit. Crop damage due to Tuta is usually 100%.
Where are they wreaking their havoc?
Everywhere! They were known to be denizen to South America, hence the name. However, they are now well established in Central Europe, and have found their way as far east as Iran, Afghanistan and Russia.
When does Tuta take on pandemic proportions?
Sadly, all through the year because they can raise as many as 8 broods every year and the crops are prone to destruction at every stage of their life-cycle.
Who can do something about Tuta?
Evidently very few because they have developed resistance to Organophosphate and Pyrethroid based pesticides. While there are claims of Spinosad, Imidacloprid and Bacillus thuringiensis providing some form of protection, but there is no known evidence to the efficiency of these new pesticides.
