Fall Armyworm (FAW)

 

What to study?

For prelims and mains: FAW- causes, effects, concerns and measures needed.

 

Context: Maize crops falling victim to fall armyworm in Bihar. Reports of the pest attacking crops have been reported from a number of districts in the state, India’s third-largest maize producer.

 

What is FAW?

It is a native of the tropical and sub-tropical regions of the Americas.

First detected in the African continent in 2016. Since then, it has spread to other countries such as China, Thailand, Malaysia and Sri Lanka.

In India: It was reported in India for the first-time in Karnataka. Within a span of only six months, almost 50 per cent of the country, including Mizoram, Maharashtra, Karnataka, Tamil Nadu, Andhra Pradesh, Chhattisgarh, Madhya Pradesh, Gujarat and West Bengal, has reported FAW infestations.

 

What makes FAW dangerous?

  • It is the polyphagous(ability to feed on different kinds of food) nature of the caterpillar and the ability of the adult moth to fly more than 100 km per night.
  • Given its ability to feed on multiple crops — nearly 80 different crops ranging from maize to sugarcane — FAW can attack multiple crops.
  • Similarly, it can spread across large tracts of land as it can fly over large distances. This explains the quick spread of the pest across India.

 

How FAW affects output?

  1. Till date, India has reported FAW infestation on maize, sorghum (jowar) and sugarcane crops. Maize has been the worst affected as most maize-growing states in southern India have been affected by the pest.
  2. FAW infestation and drought has led to a shortfall of nearly 5 lakh tonnes in output, prompting the central government to allow import of maize under concessional duty. Maize is the third most important cereal crop grown in the country and the infestation, if not checked in time, can wreck havoc.
