Situation Update: Locust Crisis in Madagascar - 30 October 2013
With the onset of the rainy season in late September, ecological conditions are becoming suitable for the maturation of the swarming populations and their subsequent mating and egg-laying (adequate soil moisture and grass greening). Hatching of non-swarming populations was already reported.
Several swarms, whose size was of 3 600 hectares on average but could exceed 10 000 hectares, were observed since the beginning of the extensive aerial survey, on 26 September. These swarms consisted of immature, maturing or already mature adults.
Currently infested areas extend as far North as the northwestern part of the invasion area. It is expected that hoppers groups and bands will form from mid-November in the West.
