One newspaper account, which I saw, reported: “The north and centre of Entre Rios are simply covered with locusts both in the hopper and flying stages. The city of Paraná was invaded by a swarm calculated to be nine miles in front and several miles in depth, and so thick that the sun was partially obscured. Other cities are hurriedly being enclosed with screens in order to keep the locusts at bay. In places they have completely devastated the vineyards, orchards and maize. In many places a cry of desperation is heard. In the province of Santa Fé swarms of fliers passed Santa Isabel bearing east; enormous swarms passed General Lopez proceeding west; Monte Vera reports the passage of fliers towards the north and south. The work of destruction goes on successfully. To-day between Zarate, Pilar and Campaña were destroyed sixty-eight thousand kilos (more than seventy-four tons) of saltona (hoppers).” The farmer is in a quandary what to do. If he had only a hundred acres to look after it would not be so difficult, but none of them have fewer than thousands of acres. How to secure the labour to drive these locusts is a difficult problem. The government has passed laws requiring each landowner to maintain men to fight the locusts, on the basis of about one to each thousand acres. If this is not done the owner is fined. The general method is to dig pitfalls three or four feet deep, the outer edge of which is protected by overlapping sheets of corrugated iron. These traps run out for some distance. The locusts, while still in the hopping stage, are driven towards this trap until these pits are oftentimes nearly filled up with their bodies. They are then covered up with a coating of earth, and they die very quickly. If this work is thoroughly done it is quite efficacious, but it is oftentimes difficult to get sufficient labour, for it is unpleasant work because of the nauseating odour from the bodies of the crushed locusts. Unless the work is systematically and thoroughly done, however, it does not have much effect, for a few millions will not be missed. If one man does his work well, and his neighbour is indifferent to his duty, then his work is for naught, as they will soon swarm over his land again from his neighbour’s fields. United effort alone is efficacious, and that is what the government is endeavouring to either induce or compel the people to do. It has a commission at work studying this and other insect pests, and the best way to exterminate them.
