Management of Fall Army Worm of Maize, Spodoptera frugiperda, with Green Synthesis Silver Nanoparticles

The fall armyworm (FAW), Spodoptera frugiperda is a polyphagous and economically important insect pest originated from tropical sub-tropical parts of America. Being strong flier, climatic adaptation large host range makes it serious threat to food security. It responsible for high economic losses in many cash crops, vegetables cereals. overreliance overuse pesticides the management FAW posed problems including insecticide resistance, resurgence pests, biotype development environmental hazards. To combat these problems, most alternative use green synthesis nanoparticles biocontrol agents which have been proven as eco-friendly technology control. current study was, therefore, planned evaluate toxicity different plant based synthetic agent (Trichogramma spp.) against armyworm. Silver neem resulted highest (83%) lowest (40%) mortality 2nd instar larvae FAW. However, due silver tobacco, onion, mint, ginger datura was observed 86%, 63%, 76%, 63% 73% while 30%, 33%, 23% 16% respectively. In view findings could be recommended potential bio-based chemicals control S. frugiperda.
