Mutants with delayed cell death of the ptilinal head muscles in Drosophila.
Kimura K, Tanimura T. Kimura K, et al. J Neurogenet. 1992 May;8(2):57-69. doi: 10.3109/01677069209084152. J Neurogenet. 1992. PMID: 1634997
During eclosion, the fly makes use of a membranous sac, the ptilinum, which is later retracted into the head capsule. Six of the eight sets of muscles involved in the retraction then undergo degeneration. ...

Effect of cooling rate on the survival of larvae, pupariation, and adult emergence of the gallfly Eurosta solidaginis.
Bale JS, Hansen TN, Nishino M, Baust JG. Bale JS, et al. Cryobiology. 1989 Jun;26(3):285-9. doi: 10.1016/0011-2240(89)90024-2. Cryobiology. 1989. PMID: 2743790
A number of flies in each group emerged with malformed (unextended) wings and an unretracted ptilinum on the head capsule. The percentage emergences of normal flies at the four cooling rates and from the control were 3, 0, 17, 47, and 57%. ...

The Iroquois homeobox genes function as dorsal selectors in the Drosophila head.
Cavodeassi F, Modolell J, Campuzano S. Cavodeassi F, et al. Development. 2000 May;127(9):1921-9. doi: 10.1242/dev.127.9.1921. Development. 2000. PMID: 10751180
In mosaic animals, the removal of the Iro-C transforms the dorsal head capsule into ventral structures, namely, ptilinum, prefrons and suborbital bristles. Moreover, the Iro-C(-) cells can give rise to an ectopic antenna and maxillary palpus, the main derivatives of the an …

Kinetosomes in insect epidermal cells and their orientation with respect to cell symmetry and intercellular patterning.
Whitten JM. Whitten JM. Science. 1973 Sep 14;181(4104):1066-7. doi: 10.1126/science.181.4104.1066. Science. 1973. PMID: 17731269
Paired flagellar basal bodies or kitnetosomles are described for tarsal, pulvillar, wing, proboscis, ptilinum, and tracheal epithelial cells in the fly Sarcophaga bullata. ...

SEM observation of the insect prepared by microwave irradiation.
Koga D, Ueno M, Yamashina S. Koga D, et al. J Electron Microsc (Tokyo). 2003;52(5):477-84. doi: 10.1093/jmicro/52.5.477. J Electron Microsc (Tokyo). 2003. PMID: 14700080
The ptilinum of the fly and the compound eye are among the most fragile organs encountered during conventional procedures of morphological sample fixation. ...
