2021年12月1日 · Here, we review the tissue architectural changes that occur during epidermal morphogenesis in the Drosophila pupa, with a particular emphasis on the underlying mechanical principles. We highlight recent developments in our understanding of adult epidermal morphogenesis.

Drosophila (/ drəˈsɒfɪlə, drɒ -, droʊ -/ [1][2]) is a genus of fly, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to …

2018年7月11日 · 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.

Drosophila melanogaster exhibits complete metamorphism, meaning the life cycle includes an egg, larval (worm-like) form, pupa and finally emergence (eclosure) as a flying adult. This is the same as the well-known metamorphosis of butterflies.

Drosophila display a holometabolous method of development, meaning that they have three distinct stages of their post-embryonic life cycle, each with a radically different body plan: larva, pupa and finally, adult.

Pupa: After 4 days of voracious feeding, the 3 rd instar larva encapsulates itself inside a hard and dark-colored puparium. It is in this pupal stage, where the metamorphosis of D. melanogaster takes place, giving rise to wings and legs. At room temperature conditions, the duration of metamorphosis lasts for 4 days.

2024年9月26日 · Pupa: Soon after everting its anterior spiracles, the larval body shortens and the cuticle becomes hardened and pigmented. A headless and wingless prepupa forms. This stage is followed by the formation of the pupa with everted head, wing pads, and legs. The puparium (outer case of the pupa) thus utilizes the cuticle of the third larval instar.

Wing development in Drosophila melanogaster is an ideal model for studying morphogenesis at tissue level. These appendages develop from a group of cells named wing imaginal discs formed during embryonic development.

In addition to measuring growth, fecundity and longevity, we used several behavioral and physiological assays to determine if and how altering food media influence wild-type (Canton S) Drosophila melanogaster, at larval, pupal, and adult stages.

2024年12月20日 · We describe steps for using the hybridization chain reaction (HCR) in early and late Drosophila pupal stages (and larval imaginal discs). This protocol facilitates the study of dynamically changing patterns in gene expression during pupal development.
