Xiao Qiang, mostly refers to cockroaches. It is said that cockroaches were originally called Xiao Qiang in Guangdong and Hongkong. The nickname Xiao Qiang comes from Stephen Chow's film Tang Bohu Electric Appliances. Cockroaches have many names, but the official name is cockroach.
The nickname "Xiao Qiang" comes from Stephen Chow's movies. In 1993' s movie "Smelly Alley in Tang Bohu", Tang Bohu, played by Stephen Chow, pretended to be a poor man who betrayed his buried father in order to enter Washington, but met an opponent who betrayed his buried family, and even his pet dog who had been with him for many years died on the spot, so Zhou Ling took the initiative to call the cockroach that was accidentally trampled to death beside him "Xiao Qiang" and cried for it as a pet for many years.
The name comes from the fact that most children in Hong Kong are called Xiao Qiang. To show Stephen Chow's love for trampled cockroaches. Hence the name "Xiao Qiang".
Cockroaches have a strong vitality, and the strongest cockroach family is Blattella germanica (also known as the cockroach that can't be killed). It is very small, about 10- 15mm long, and its adult is brown, which is the dominant species of Blattea in China in recent twenty years.
Except in the house, it is almost everywhere in restaurants, restaurants, hospitals, ships, trains and passenger planes. In recent twenty years, Blattella germanica has spread from a few big cities to most small and medium-sized cities in China, even remote small market towns and rural areas. According to the data of the National Center for Disease Control and Prevention, a female cockroach can breed up to one million offspring a year.
Cockroaches like to live in warm, humid, food-rich and crevice places, which are the four basic conditions for their reproduction. All buildings where people live and live generally have these conditions, so cockroaches have become health pests that infringe on thousands of households.
Love of warmth and tide is an important habit of cockroaches. It is not difficult to find that the kitchen is always the most seriously violated place, whether in restaurants, families, or on trains and ships. Even in the kitchen, they generally like to live near stoves and pools.
Extended data:
According to the ecological habits of cockroaches, a biologist once came to a conclusion: if there is a global nuclear war on the earth one day, all creatures in the affected area, including humans and even fish, will disappear, and only cockroaches will continue their lives! This is because under normal circumstances, the radiation that the human body can bear is 5 rem, and once the total radiation exceeds 800 rem, it will die.
Blattella germanica can tolerate 9000~ 105000rems, and Periplaneta americana can tolerate 967500rems! So cockroaches can survive even if there is a nuclear explosion. The US government spends $6,543.8+$0.5 billion annually to eliminate cockroaches, which is about twice the budget for AIDS prevention.
