"Reproduction and Development of Insects" Reproduction and Development of Biological Organisms PPT Courseware 4
1. Reproduction and development of silkworm
Reproduction and development of silkworm
1. Reproduction method – sexual reproduction
2. Development process - eggs, larvae, pupae, adults
3. Complete metamorphosis - the development process goes through four stages: egg, larvae, pupa and adult. This development process is called complete metamorphosis. For example: flies, mosquitoes, bees, butterflies, ants, fleas, beetles, etc.
The development of insects goes through four stages: egg, larvae, pupa and adult. This development process is called complete metamorphosis. Such as: silkworms, bees, cabbage butterfly, mosquitoes, flies, etc.
During the development of new individuals from fertilized eggs, the morphological structures and living habits of larvae and adults are very different. This development process is called metamorphosis.
The development process that goes through the four stages of egg, larvae, pupa and adult is called complete metamorphosis.
2. Development of other insects
The development process that goes through three stages of egg, nymph, and adult is called incomplete metamorphosis.
Reproduction and development of locusts:
1. Reproduction method – sexual reproduction
2. Development process - eggs, nymphs, adults
3. Incomplete metamorphosis - The development process of locusts goes through three stages: egg, nymph, and adult. Such a development process is called incomplete metamorphosis. For example: mole crickets, praying mantises, crickets, cicadas, cockroaches, dragonflies, aphids, etc.
