What is the summary of Insects and Pea Elephant ?

Insects remember bean elephants.

generalization. Fabre.

By reading various ancient texts about food and drinking, as well as rumors heard in the countryside, it is surmised that this guy is introduced from other places, not from the original. Because when I came, I didn't bring my fellow countrymen, and here we have weevils.

Be cautious, because you don't know this new thing, so you don't have much interest in beans. (That's a good idea for doing research.) I think another reason is that the production of other beans is also abundant, and the weevils have enough to eat, so they don't have the idea of beating beans.

In order to test his reasoning, Fabre also sent a package of dried beans that had been infested by insects from the mainland of Kidney Bean's hometown. The eggs are separated from the top and kept in jars.

Middle. He put the newborn weevil in his experimental field, and found that the worms did not eat the beans and starved to death. After several experiments, Fabre found that Phaseolus vulgaris did not like to eat fresh beans and preferred dried beans stored in warehouses.

At this point, Fabre is done.

The main contents of the bean elephant in "Insects" are as follows:

Phaseolus vulgaris is a Coleopteran insect that is listed as a harmful pest by China for foreign quarantine. The insect is widely distributed, and the host plants are mostly beans, broad beans, wheat, buckwheat, peas, red beans and lentils, etc., and the larvae eat in the beans, causing serious harm to the stored edible beans.

It mainly writes about the pea elephant's help to humans, highlighting the pea elephant's ability to meet the characteristics of humans. "Insect Story", also known as "Insect World", "Insect Story", "Entomological Notes" or "The Story of Insects", is a long popular science literature written by French entomologist and writer Jean Henri Casimir Fabre, with a total of ten volumes.

This work is a masterpiece of entomology that summarizes the species, characteristics, habits, and marriage habits of insects.

Souvenirs Entomologiques (also known as "The World of Insects", "Insect Story", "Entomological Notes") is a long biological work written by French entomologist and writer Jean-Henri Casimir Fabre, a long work of biology in ten volumes. The first volume was published in 1879 and the whole book was published for the first time in 1907.

This work is an insect biology work that summarizes the species, characteristics, habits, and marriage habits of insects. The author integrates the colorful life of insects with life perceptions, and reveals his respect and love for life between the lines.

1. The main content of "The Pea Elephant" in the insect book: It is the largest butterfly in Europe, wearing a maroon velvet coat and a white fur tie. The wings are full of gray and white spots, a pale white zigzag line passes through it, the periphery of the line is soot white, the wings ** have a round spot, like a big black eye, the pupils are flashing with black, white, maroon, cockscomb red rainbow-like unpredictable colors.

2, "Insects".

is a book about the life of insects, involving dung beetles.

Ants, Sisyphus.

There are more than 100 kinds of insects such as insects. In this world, there are about 1 million species of insects known to mankind, accounting for 5 6 of all known animal speciesAnd there are still millions of unknown insects that are still waiting to be discovered and understood. Fabre.

In the mid-19th century, in addition to teaching at school, he and his children observed all kinds of insects in the fields, named them, and sang the praises of them.

The main content is to write about the pea elephant's help to humans, highlighting the pea elephant's ability to meet the characteristics of humans.

The author integrates the colorful life of insects with his own life perceptions, and looks at insects with human nature. Reading between the lines reveals the author's respect and love for life.

Phaseolus vulgaris is an important pest of many species of beans and other legumes, and the larvae eat inside the beans and cause serious harm to the stored edible beans. Once introduced, it will bring significant losses to China's bean production and also have a serious impact on bean exports. China has listed it as a harmful insect pest for foreign quarantine to prevent the introduction of the insect.

Living environment. The field ecological conditions in Yanbian area are completely suitable for the growth and development of Phaseolus vulgaris, especially along the Yangtze River, which has more suitable temperature and humidity conditions. According to the experimental observations, most of the elephants in the cage field can develop from eggs to mature larvae or pupa, and a small number can emerge into adults, and then enter the indoor warehouse with the harvest of beans for reproduction.

It overwinters in barns as mature larvae or pupae and cannot overwinter in the field. Because Phaseolus vulgaris eggs are not sticky, they are rarely laid in the inner or outer folds of the cracked pods. Adults mainly use their mouthparts to bite a slit or small hole on the inner ventral line of a mature or near-mature pod, and then extend the ovipositor into the slit to lay eggs, which can reduce the egg loss rate.
