Fall armyworm (Spodoptera frugiperda): a threat to food security for south Asian country: control and management options: a review.
Fall armyworm, Spodoptera frugiperda (Smith,1997) is a sporadic pest with a diverse host range challenging food security over 300 million people by causing severe damage to world's 1st rank cereal crop maize. FAW is native to tropical and sub-tropical region of America spreading worldwide uncontrollably from last three years to Africa and Asia. FAW is becoming tolerant to many insecticide use strategies and difficulty in finding and surveying field infestation with simple protocols. This review targets on insect biology description, life cycle, behaviour, damage to maize, and potential management strategies. The review concludes that synthetic chemical should be avoided as possible but should be used in severe damage more than 50%. The best way to make plant free of FAW attack, to make plant healthy by increasing resistibility power of plant itself in such case manage soil nutrient along with soil health by increasing humus content and use of wild type or local variety is best way to avoid FAW attack.
