The German cockroach1 has developed a strong resistance to insecticide due to the widespread use of chemical bug2 sprays, according to a research led by Purdue University in Indiana.

印第安纳州普渡大学的一项研究显示,由于化学杀虫喷雾剂的广泛使用,德国小蠊对杀虫剂已产生了很强的抵抗力。
?
The German cockroach is one of the most common black beetles3 living around us. It can pose a threat to people's health, as it can trigger allergies4 and asthma5.
?
In the study, the researchers used individual and combination insecticides, but nothing could wipe out the population of German cockroaches6.
?
"Cockroaches developing resistance to multiple classes of insecticides at once will make controlling these pests almost impossible with chemicals alone," said the research report published in the journal Scientific Reports.
?
The scientists from Purdue University said the super-immunity gene7 is passed on to the insect's offspring, so people need to find non-chemical measures to control cockroach populations, such as traps.
