バッタの第2世代が形成中

An increasing number of second-generation immature swarms continue to form in northwest Kenya. The bulk of swarm formation is likely to occur during the next two weeks followed by a decline in July.

Before migration, swarms will remain for a short time during which there is a considerable threat to crops and pastures in Turkana and Marsabit counties. Thereafter, the swarms are expected to migrate northwards to the summer breeding areas in Sudan and Ethiopia where they will mature quickly and lay eggs. Some of the swarms will take about a week to cross South Sudan to reach South Kordofan and South Darfur while other swarms will move north to east and northern Ethiopia. Any swarms in northern Somalia can migrate across the Indian Ocean to the summer breeding areas along both sides of the Indo-Pakistan border.

今はまだバッタは春の交配中らしくケニアで第2世代が作られていて、これがケニアから北のスーダンに移動していく。

そのあとはインドパキスタンで夏の交配を行うらしい。

となると7月に夏の交配が広がるかどうかが、食糧へ与える影響を決めることになる。

7月、8月がバッタのピークかな。

9月になったら落ち着くということか。
