Argentina and Brazil are monitoring the movement of a 15-square-kilometer locust swarm in Argentina’s northeast that’s crossing South America.
The insects, which entered Argentina from Paraguay, are heading toward Uruguay. While they are not expected to affect Brazil’s crops, the nation’s agriculture ministry on Thursday declared a state of emergency in two southern states in order to allow officials to take preventive measures.
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.
A representative from the Aprosoja growers association in Rio Grande do Sul said they feared the locusts would enter the state where corn is still being harvested and wheat being grown.
