The spontaneous generation

He studies particularly the Insecte S and the parasite S. He makes appear in 1668, Esperienze Intorno went Generazione degl' Insetti , where he makes the demonstration which there does not exist spontaneous Generation at the Mouche S. Those are born from eggs laid by other flies and do not appear spontaneously.

The venom of the vipers

He also studies, seems he at the request of the large-duke, the Vipère S and the effects of their bite. Redi shows that venom is a yellowish fluid which runs out of the teeth and which it is stored in the head of the animal. It also proves that only the venom injected into the body at the time of a bite can result in death, introduced venom is without harmfulness. After having carried out many experiments in front of the large-duke himself, it makes appear in 1664, Osservazioni Intorno ale Vipere . Its observations are disputed by many doctors and scientists of his time, in particular Moyse Charas, pharmacist with the Jardin of the king to Paris. Redi leads many other experiments then in order to show the veracity of its observations. It will be necessary to await work of its compatriots, Felice Fontana, who will show, in 1767 and 1781, in an irrefutable way the exactitude of the work of Redi.

Redi is also a poet: its most famous work is Bacchus in Tuscan .

A crater on Mars was dedicated to him.
