Eating and drinking Lhasa incest beetles in coffee beans

The tiny coffee fruit beetle can be said to be the Cersei and Jamie of the insect world, and the incest place of these bugs is the coffee beans you usually drink. Discovery News calls the coffee fruit beetle the most threatening pest to coffee plants in the world. Although drinking coffee inhabited by these bugs is not harmful to the human body, if you like coffee beans without bugs, you should move on.

These bugs will eat holes in the coffee beans and lay eggs in the holes. Once the eggs hatch into larvae, the larvae continue to eat and eat in the beans. It results in the decline of the quality of coffee beans and brings economic losses to the farmers who grow coffee beans.

Ted Lingle, executive director of specialty American coffee at the USDA, said: "these pests will reduce coffee production by up to 20%, and the price of worm-eaten coffee beans will drop by 30% and 40%." Coffee plantations all over the world are deeply affected by this small pest. "

According to a new study, these bugs not only produce their offspring in coffee beans, but also have sex with brothers and sisters in a coffee bean, which is incest.

The study found that although the insect does not even need to reproduce sexually, the female chooses to mate with her brother in order to occupy the coffee beans as much as possible. Scientists have found that coffee beetles are parthenogenetic and that females can reproduce without males.

It is reported that most of the coffee beans infected with this pest have been removed and consumers cannot buy them, but some of the pests may have escaped the test and mixed into bagged coffee. here's how to tell the difference between these coffee beans with incest bastards.

Generally speaking, female beetles drill holes in coffee beans to escape, so worm-eaten coffee beans are more empty than ordinary coffee beans. Discovery News also said that the bug likes Arabica coffee beans best, and if you also like Arabica, you are more likely to eat worm-eaten coffee beans.

These bugs are not only harmful to coffee beans, but also have a very serious social impact.

FernandoE, an insect researcher from the United States Department of Agriculture. "millions of people around the world live by growing coffee beans, and only protecting the economic interests of growing coffee beans can protect these growers," Vega said on the USDA website.
