| Summary: | Some species of locust, an insect of the family Acrididae, have the capability of multiplying enormously, given rise to destructive swarms which cover enormous distances. There is a vast number of species extended through all the continents. Some of the most important are the Schistocerca gregaria, the Locusta migratoria, the Nomadacris septemfasciata, and the Dociostaurus maroccanus. These locust plagues, historical responsible for problems in alimentation, have still catastrophic results, as it has recently happened in Africa. The first steps for the international control of the locust plague happened during the 2nd decade of this Century in the Agricultural International Institute, launched in Rome in 1905. Under this organisation a meeting between several countries was held to fight the insect in October 1921.
Nevertheless, the international Conferences, which marked the definite scientific development of the problem, didn't happened until the following decade. The first convention was held in Rome, 1931; the last one in Brussels, 1938. The fact that the plague grew enormously after 1928 in Africa explains this intense activity. Coincidental with the development of the African plague, an intense scientific literature began to be published. Especially important was the work by Boris P. Uvarov, Locusts and grasshoppers (London, 1928), the compulsory reference for all these who research on the topic. This paper tries to analize the reason for European metropolis to become interested in the scientific and organising aspects of the locust in Africa. |
