Situation Update: Locust Crisis in Madagascar - 8 May 2014
May 2014

The 2nd generation of breeding of the rainy season came to an end. In early April, numerous and dense medium-size swarms of young winged locusts were present in the invasion area, mainly in western Madagascar.

Later in the month, several swarms reached the “Hautes Terres”, where they were probably carried up by the strong winds generated by the tropical cyclone Hellen, which hit northwestern Madagascar (Mahajanga area) early April. Some of them even reached the suburbs of Antananarivo, creating some trouble but no damage. Huge early instar hopper bands of the 3rd generation were detected in the northwestern part of the outbreak area (southeast Toliara) at the beginning of April.

Therefore, with the formation of new swarms, the impact of Hellen and the results of control operations, the shape of the infested area changed as compared to the previous month, with a lesser North extension but a greater extension towards the East, in the central part of the Island.

The rainfall decreased in April but the vegetation cover is still green and the soil moisture relatively important, which is suitable for the development of the 3rd generation of the Migratory Locust.
