Pupal
Definition:
(a.) Of or pertaining to a pupa, or the condition of a pupa.
Example Sentences:
(1) Some pupal motor neurons, however, show a marked non-linear response to depolarizing current injection (Fig.
(2) The four distinct neuroblasts proliferating in the early larval and late pupal stages are identical; they lie in the cortex above the calyces of the mushroom bodies (corpora pedunculata), proliferating over a period twice as long as that for the other neuroblasts.
(3) The P cytotype-like effects include suppression of snw germline hypermutability, snw somatic mosaicism, pupal lethality, and gonadal dysgenic sterility.
(4) As the period of exposure to the low temperatures increased, pupal survival decreased.
(5) Thus it appears that a cerebral neuropeptide specifically inhibiting JH I synthesis by the CA is present in Manduca on day 4 of the last larval instar, a time when the hemolymph titer of JH must drop to ensure the occurrence of pupal commitment.
(6) Genetic information on 25 enzyme polymorphisms in Drosophila subobscura, the location of corresponding genes, and cytological and genetic maps of the chromosomes are presented, as well as photographic maps of the salivary gland chromosomes in the third instar larva and white-case early pupal stages.

(8) The facilitation of eclosion by adult colony members appears to be an obligatory process in the development of this species; pupae denied the aid of adult workers during eclosion are unable to remove the pupal cuticle and rapidly succumb.
(9) Cautery off the midline produced asymmetries in the pattern of pupal commitment; when placed close to the midline, such cauteries prevented pupal commitment in the region "downstream" of the cautery, suggesting that a signal (diffusible or transducible) emanates from the midline.
(10) In the pupal brains, ecdysteroid receptors reappear in a new population of neurons.
(11) The lethal phase of various apparent null mutants was determined and found to occur mainly in the pupal stage.
(12) These proteins are later sequestered by the pre-pupal fat body.
