20 17 the fact that the locust plague in Shandong was eaten up was actually a bit exaggerated, but at that time, some people did eat locusts, and there were many people who bought them at the scene, so it gave people the impression that the locusts were eaten up.
Actually, it's not. The locust plague in 20 17 was actually very serious in Russia at that time, but it was much better in Shandong, China. This is no longer a disaster. For the people in Shandong, China, it is protein. The price of locusts is very expensive, which is equivalent to money.
Causes of locust plague:
1, drought
From the environmental point of view, it is mainly caused by drought.
2. Living habits
From its life habits, mainly:
(1) is very gregarious.
(2) Strong fertility.
(3) It is omnivorous, that is, it can eat a variety of plants.
(4) Its flying ability is very strong and difficult to control.
(5) Its eggs are buried deep underground and are not easy to be destroyed.
The plague of locusts is easy to flood after warm winter.
Global warming, especially the rising temperature in winter, is conducive to the increase of locusts' overwintering eggs and provides "eggs" for the outbreak of locust plague in the following year; In addition, the combined effects of climate warming, intensified drought, grassland degradation and other factors will provide suitable places for locusts to lay eggs. Locusts have strong adaptability to drought, because other insects and birds can't survive in this situation, and a filamentous fungus that can cause locust diseases is suppressed, so its number is greatly increased. Therefore, experts predict that with the trend of global warming, the scale of locust plague will become larger and larger in the future, which will have a serious impact on grain production in China.
