TL;DR: New evidence is given that the juvenile hormone has an indirect effect on respiration due to its increasing the amount of tissue that actively participates in the total metabolism of both larvae and adults.
120 citations
TL;DR: The red colour represents a more effective signal than the yellow; predation by birds could have played a crucial role in selectively favoured evolutionary transitions from yellow to red coloration in pyrrhocorids.

TL;DR: A new member of the AKH/RPCH family was isolated and identified from the corpora cardiaca of the firebug Pyrrhocoris apterus, and is the first identified adipokinetic hormone described in a representative species of the suborder Heteroptera.

TL;DR: Present review provides the first selective summary of data published in almost 300 papers on the red firebug, Pyrrhocoris apterus, with a focus on the problems of determination of metameric pattern, cold hardiness and biorhythms.
Abstract: The red firebug, Pyrrhocoris apterus (L), has been a convenient model for biological research for a long time The interest in P apterus increased especially with the discovery in the mid-1960's of the so-called ''paper factor'', ie, a substance with juvenile hormone activity Considerable research has been done on this model insect in research topics such as biogeography, embryology, developmental and reproductive biology, theoretical and applied endocrinology, biochemistry, cytogenetics and formal genetics, bionomics, ethology, pathology, voltinism, diapause, wing polymorphism, migration, pathogens, symbiotes and predators Some of the newest studies are directed toward the problems of determination of metameric pattern, cold hardiness and biorhythms Present review provides the first selective summary of data published in almost 300 papers

TL;DR: Reactions of nine passerine bird species to the firebug Pyrrhocoris apterus wildtype (brachypterous adults) and its artificially obtained (painted) brown non-aposematic variant were compared and can be interpreted in terms of the presence of a higher proportion of experienced individuals among insectivorous than among omnivorous species.
Abstract: In spite of the existence of many experimental studies on the function of warning coloration in insects, little is known about the universality of reactions of different predators towards a particular warning signal Reactions of nine passerine bird species, namely Parus major , Parus caeruleus , Aegithalos caudatus , Erithacus rubecula , Turdus merula , Sylvia atricapilla , Fringilla coelebs , Carduelis chloris and Emberiza citrinella , to the firebug Pyrrhocoris apterus wildtype (brachypterous adults) and its artificially obtained (painted) brown non-aposematic variant were compared Most insectivorous birds (great tits, blue tits, robins and blackcaps) distinguished between aposematic and non-aposematic bugs, attacking the former less often Partly granivorous buntings and finches did not distinguish between them, and attacked both variants equally As all the birds were caught in the wild, the results can be interpreted in terms of the presence of a higher proportion of experienced individuals among insectivorous than among omnivorous species Two insectivorous species differed from others The heaviest blackbird attacked and killed aposematic as well as non-aposematic firebugs, and, in contrast, the lightest long-tailed tit avoided both variants © 2003 The Linnean Society of London, Biological Journal of the Linnean Society , 2003, 78, 517–525
