Classification and host plants
Class: Insects
Order: Lepidoptera
Suborder: hetoneuri
Family: Bombicides
Genus: Bombyx
Species: B. mori L.
Host plants: White mulberry.
Its larva, known as silkworm has a considerable economic importance as it is used in the production of silk. His diet consists exclusively of mulberry leaves. It is a species native to northern China.
Biological cycle
The four molts and the five ages in which the larval life of the silkworm (Bombyx mori) can be considered divided have about the following distribution and duration:
- 1st age: lasts about 5 days and ends with the first moult;
- 2nd age: lasts 4 days and ends with the second moult;
- 3rd age: lasts 5 days and ends with the third moult;
- 4th age: lasts 6 days and ends with the fourth moult;
- 5th age: lasts 8-10 days and goes from the fourth wetsuit to the cocoon formation.
In favorable breeding conditions, the total duration of larval life is about one month (in fact, the lower the quantity of food and the temperature, the greater the duration of larval life). Flicker occurs on average 15 days after the start of cocoon formation. The metamorphosis occurs about the 5th day after the formation of the cocoon.
