How did Fabre observe insects?

Falb's usual style is to add neither one nor one less.

Fabre. The method of studying insect behavior is observation.

Scientists study animal behavior mainly by observation and experiment.

1. Scientific observation can be made directly with the naked eye or with the help of a magnifying glass.

Instruments such as microscopes, or the use of tools such as cameras, video recorders, video cameras, etc., sometimes also require measurements Steps: Have a clear purpose; It is necessary to be comprehensive, meticulous and realistic, and record in a timely manner; Be planned and patient; Think positively; It is necessary to exchange views and hold discussions.

Second, the experiment is an important way to explore life, the process of the problem is to find the problem, put forward the problem, after the problem is found, the application of existing knowledge to make assumptions about the problem, the development and implementation of the plan, according to the experimental phenomenon, draw conclusions, and finally express the process and conclusion

The essential difference between the observation method and the experimental method is that the experimental method exerts an influence on the research object, and the experimental method is based on the observation method.

When Fabre studied the behavior of insects, he did not change the living environment of insects, nor did he exert any influence on them; Therefore, Fabre's method of studying insect behavior is observation.

Fabre. Like a detective, he followed and observed insects for a long time, constantly making assumptions, reasoning repeatedly, and rigorously verifying, and spent a lot of time observing each kind of insect: 20 years for soil bees and 30 years for tunnel bees.

Fabre's observations are very comprehensive, meticulous, and factual, and he records them anytime and anywhere.

The most important thing is that Fabre has a plan and patience; Fabre's own consistent style is to "accurately describe the facts observed, adding nothing and ignoring nothing".

Fabre made an all-round, three-dimensional observation of its appearance, predatory habits, body structure, and living environment. If you can see it directly with the naked eye, there are some smaller insects that you can see with a magnifying glass.

Fabre's first problem was the fact that the insects were playing dead. The first test subject he found was the big-headed black step armor. This insect likes to play dead very much, as soon as it moves, it immediately shrinks its whole body and does not move, and it will last for more than 50 minutes before it returns to normal and continues to move.

Fabre has conducted many experiments on it in different scenarios, and has also used several other insects for experiments, such as leaf beetles, high-backed beetles, corpse-eating insects, Cleon beetles, bowl-backed beetles, goldsmith flower beetles, heavy beetles, ladybugs and a series of insects. Some insects play dead for a very short time, or even don't play dead.

This ** problem reflects Fabre's seriousness and meticulousness in dealing with things, and every ** problem has been repeatedly verified before it is determined.
