Development Term : FBdv:00005339 third instar larval stage Fly Development

Namespace  FlyBase development CV Obsolete  false
description  The third larval instar begins at the second larval molt and ends at puparium formation. Anterior spiracles are open to the outside; posterior spiracles have three openings each, and four groups of large branched hairs. The salivary glands extend to the second abdominal segment, with cells larger in the posterior than in the anterior of the gland. Mouth hooks typically have 9-12 teeth. About 24 hours before pupariation (at 25 degree C), larvae stop feeding and climb away from their food. Duration at 25 degrees C: approximately 48 hours (72-120 hours after egg laying; 48-96 hours after hatching).

FBdv:00005336 larval stage The stage of the Drosophila life-cycle from hatching to the beginning of puparium formation.
FBdv:00005339 third instar larval stage The third larval instar begins at the second larval molt and ends at puparium formation. Anterior spiracles are open to the outside; posterior spiracles have three openings each, and four groups of large branched hairs. The salivary glands extend to the second abdominal segment, with cells larger in the posterior than in the anterior of the gland. Mouth hooks typically have 9-12 teeth. About 24 hours before pupariation (at 25 degree C), larvae stop feeding and climb away from their food. Duration at 25 degrees C: approximately 48 hours (72-120 hours after egg laying; 48-96 hours after hatching).
FBdv:00005338 second instar larval stage The second larval instar begins at the first larval molt and ends at the second larval molt. Larvae are actively feeding and crawling in the food. Distinct anterior spiracles are present as enlargements at the end of the tracheal trunk, but not open to the outside; posterior spiracles have three openings each, and four groups of small unbranched hairs. The salivary glands extend to the first abdominal segment, and have cells that are uniform in size. Mouth hooks typically have two or three teeth. Duration at 25 degrees C: approximately 23 hours (49-72 hours after egg laying; 25-48 hours after hatching).
FBdv:00000000 Drosophila life The life of an individual of the species Drosophila melanogaster, from fertilisation to death.
FBdv:00007008 occurrent An entity that has temporal parts and that happens, unfolds or develops through time. Sometimes also called perdurants. (Definition imported from 'occurrent ; BFO:0000003', which is equivalent to this term.)
FBdv:00005259 developmental stage A temporal subdivision of a developmental process.
FBdv:00007012 life stage A temporal subdivision of a Drosophila life, delimited by major transitions in the circumstances of the organism, such as: fertilisation; hatching; pupal ecdysis; eclosion.
