BUENOS AIRES/SAO PAULO—Argentina and Brazil are monitoring the movement of a 15-square-kilometer locust swarm in Argentina’s northeast, though authorities and specialists said so far it had not caused significant damage to crops in the South American countries.
Argentine food safety body SENASA said the swarm, which initially entered Argentina from Paraguay in late May, contained about 40 million insects. It is in the province of Corrientes, near borders with Brazil, Uruguay, and Paraguay.
