What are the stages in the larval development of a fruit fly?
There are four stages to the life cycle of fruit flies, these are: eggs, larvae (maggots), pupae and adults.
How long is the Drosophila life cycle?
about three weeks
The life cycle of Drosophila is short and completes in about three weeks. Embryonic development, which follows fertilization and the formation of the zygote, occurs within the egg membrane. The egg produces larva, which eats and grows and at length becomes pupa. The pupa, in turn develops into an imago or adult.
Which is the correct hierarchy of gene activity in early Drosophila?
The correct option is (a) maternal-effect genes, gap genes, pair-rule genes, segment-polarity genes.
What type of insects development has larval and pupal stages?
complete metamorphosis
Insects with complete metamorphosis include beetles, bees, ants, butterflies, moths, fleas, and mosquitoes. Ants begin as an egg then go through many instar/larval stages and a pupal stage before becoming adults. There are three possible adult forms that an ant can become: male ant, queen ant, or female ant.
What are larvae flies?
A maggot is the larva of a fly (order Diptera); it is applied in particular to the larvae of Brachycera flies, such as houseflies, cheese flies, and blowflies, rather than larvae of the Nematocera, such as mosquitoes and crane flies.
What is the pupal stage of larva?
Pupal stage: After encapsulation of the 3d instar larva, pupal stage starts and lasts around 4 days. Many larval structures are lysed and new structures are formed. New structures are generated from the formation of the imaginal disks, developed from larval undifferentiated cells.
What is a Drosophila pupa?
Drosophila pupa as a model for developmental research The pupal stage is a phase in the life cycle of the fruit fly which follows encapsulation of the 3d instar larva inside a pupal case or puparium.
What are the stages of life cycle of Drosophila?
Following there is a brief description of the main stages during the drosophila life cycle: embryogenesis, larval stage, pupal stage and adult life. During these different stages in the fly life cycle, the structures and organs giving rise to the fly (adult) anatomy are formed.
What is the pupal stage of the fruit fly life cycle?
The pupal stage is a phase in the life cycle of the fruit fly which follows encapsulation of the 3d instar larva inside a pupal case or puparium. Pupal stage lasts around 4 or 5 days, although this time depends on the sex (sexual dimorphism: pupal stage is longer in males), circadian clocks [3] or temperature [4].
