How to deal with Chinese greedy steps frequently?

Science Fiction Network August 22 (Qin Yingying) On August 20, a number of Beijing citizens reported that China greedy (lán) step armor appeared in the home. At first glance, this kind of bug looks like a cockroach, with a black shell, with two tentacles above the head and three pairs of feet.

"Greeding Armor is a large genus, and it is generally a insect that is beneficial to humans." Liang Hongbin, an associate researcher at the Institute of Animal Research of the Chinese Academy of Sciences, said that the corrupt steps are mainly based on the tender seeds of the plants and the soft small insects as food. There is no harm to people or the environment. "Greated sideline is also a natural enemy of many pests, such as mosquito, fly maggots, and bulb -winged pests. From this perspective, it can also be said that it is a pest."

Chinese greedy steps are insects, spleen eyes, and insects. The body is black and shiny. The upper jaw part, the edge of the upper lip, the mouth, the tentacles, the front edge of the front chest and the back plate and the rear are brown -red, the abdomen is dark brown, and the head is smooth. Adults appeared in June to September and are more common types of agricultural areas.

Stewin loves to eat meat, and generally predishes insects such as red spiders and aphids, but can also eat the seeds of wheat, barley, oats and cash crops, and cause harm to crops. It is now distributed in North Korea, Japan, Russia, and China.

Some experts believe that the emergence of Chinese greedy steps in the community means that the biodiversity of the city is relatively abundant and can provide sufficient food for the greedy step armor. To block the greedy steps, experts suggest that you can use the simplest way, such as turning off the unnecessary lights and turning the window strictly. Once there is a greedy step in the home, the citizens only need to gently sweep them out with a broom.
