Fluctuation of Protandry in Eclosion of Anthocharis scolymus (Lepidoptera: Pieridae): Can Males Eclose Optimally Under Evolutionary Equilibrium?

Environmental Entomology, 1997
To elucidate the adaptive significance of protandry (males eclosing earlier than females), the eclosion patterns of males and females in a population of the univoltine pierid butterfly Anthocharis scolymus (Butler) were studied by a mark-release-recapture method over 6 yr.

Regulation of Ecdysis-Triggering Hormone Release by Eclosion Hormone

Journal of Experimental Biology, 1997
ABSTRACT Ecdysis behavior in the tobacco hornworm Manduca sexta (Lepidoptera: Sphingidae) is triggered through reciprocal peptide signaling between the central nervous system and the epitracheal endocrine system. Recent evidence indicates that eclosion hormone may initiate endocrine events leading to ecdysis through its action on ...

Expression of a silkworm eclosion hormone gene in yeast

Biochemical and Biophysical Research Communications, 1990
Recombinant silkworm eclosion hormone was produced for the first time in yeast which was transformed with a shuttle plasmid containing a construct coding a signal peptide and the mature sequence of the silkworm eclosion hormone. Successfully transformed yeast processed recombinant silkworm eclosion hormone I (EH-I) and transported it to periplasm at ...

Innervation of dipteran eclosion muscles: ultrastructure, immunohistochemistry, physiology and death

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1993
The thoracic eclosion muscles of flies die by cytotoxic attack under neural control. We have investigated the innervation, ultrastructure and immunohistochemistry of the ventral eclosion muscle of Glossina . Two neurons located in the thoracic ganglion innervate this muscle.

DISTURBANCE OF ECLOSION SEQUENCE IN HYBRID LEPIDOPTERA

The Canadian Entomologist, 1983
AbstractSome interspecific and interpopulation Lepidoptera and Orthoptera hybrids show a syndrome of developmental abnormalities referred to here as the “sequence effect.” In normal within population broods of Lepidoptera males develop slightly faster than females, but in crosses showing the sequence effect, females in one direction of the cross ...

The Circadian Clocks of Insect Eclosion

1980
Understanding the circadian timing of eclosion in insects is a pretty big undertaking. A lot of technical detail is essential and a lot of close reasoning from meticulous experiments stands in the place of direct observations on the “clock’s” unknown physiological mechanism. In that respect clockology has some of the intellectual delight of the earlier

The pupa and events leading to eclosion

1995
The pupal stage of the chironomid life cycle has attracted increasing attention since the beginning of the century, stimulated by comprehensive rearing programmes, predominantly by Thienemann and his students, notably Potthast and Bause. The systematic value of the pupal stage was appreciated early as an aid to species identification and, later, in ...

‘Killer’-cell-mediated destruction of dipteran eclosion muscles

Proceedings of the Royal Society of London. B. Biological Sciences, 1989
After successful escape from the puparium, dipteran flies lose sets of eclosion muscles located within the head, thorax and abdomen. The thoracic eclosion muscles are described, with details of the degeneration of one of them. This muscle is found to be attacked by a macrophage-like cell that attaches itself to areas around the Z-discs and sends ...
