In homozygotes for allele Indyp115, we have previously revealed two phases of embryotic lethality and lethality at the larval and pupa stages.
      
Genetic Regulation on the Black Phenotype Mutants of Moth and Pupa of Helicoverpa armigera (Lepidoptera: Noctuidae)
      
Description of the larva and pupa of Parnops glasunovi (Coleoptera, Chrysomelidae)
      
The last instar larva and pupa of Parnops glasunovi Jcbs.
      
The morphology and development of egg, larva and pupa were investigated, which has previously not been done.
      
Their shape distribution, as determined by SEM, did not differ significantly on the two modified surfaces or with respect to the bare PUPA surface.
      
A cDNA library containing 2409 singletons was constructed from whole silkworm pupae (Bombyx mori) In addition, the types of genes overexpressed in pupa were analyzed.
      
At 500 ppm, results showed that there was a significant reduction in pupa and adult stages: 65% and 25% for Cd, 50% and 25% for Cu, 100% and 95% for Pb, and 85% and 75% for Zn, respectively.
      
The survival percentages at 1000 ppm were further significantly reduced: 15% and 0% for Cd, 35% and 15% for Cu, 45% and 90% for Pb, and 65% and 35% for Zn, respectively for pupa and adult stages.
      
Immunocytochemical localization of testis ecdysiotropin in the pupa of the gypsy moth,Lymantria dispar (L.) (Lepidoptera: Lymant
      
Therefore, lower temperatures in northern localities and at high altitudes in Europe increase the duration of the egg stage and decrease that of the pupa.
      
During the pupal stage, these reserves were rapidly consumed so that the young adult contained relatively more water than the pupa.
      
The sensitive for light reception was the fourth larval instar and pupa of the maternal generation.
      
The body-weight increased gradually in the earlier instars and showed a sharp rise from late-fourth instar to the pupa.
      
Protein content also followed the growth curve except in adult female, where it was more than in the pupa.
      
The effect of diflubenzuron on larvae of Mycophila speyeri was twofold: a reduction in fecundity of the parents and an increase in pupa-larva production.
      
In addition, it was shown that these butterflies themselves secrete cardioactive substances which can be demonstrated in larva and pupa reared on artificial diet (lacking leaf powder) if tested on the isolated rat's heart.
      
Pupae are most sensitive to cyromazine within 1 hr after pupariation and with tetrahydrofuran as the carrier solvent, giving topical LD50 values of 3 μg/g for the total puparium plus pupa and 0.2 μg/g calculated for the pupa only.
      
The eggs may be laid under all four nymphal instars but not under the pupa.
      
The egg hatches only under the fourth instar or the pupa.
