Why are there locusts in Africa? This is the main reason
1. It is usually caused by an increase in vegetation and a change in land humidity and moisture conditions caused by a heavy rain. Just in September last year, an extremely strong tropical Indian Ocean Dipole positive phase event began, causing Precipitation has increased along the East African coast, and October to December is also the time when larvae emerge from the ground. Due to sufficient rainfall and good ground environment, locusts naturally grow rapidly. This is an environmental factor.
2. Another reason is that locusts have a terrifying reproductive ability. Female locusts can lay about 200 to 400 eggs. When the environment is good and the food is sufficient, it only takes just In two to three weeks, the grown female locusts will lay eggs again, so now there is a problem that the first generation of locusts are flying in the sky, and the eggs of the second generation have been buried underground, which may become a big problem in the rainy season.
