Density dependent polymorphism in the adult of Callosobruchus maculatus (Coleoptera, Bruchidae)
TLDR
A heriditary element controlling the appearance of the forms was experimentally demonstrated and it was shown that among populations of Callosobruchus maculatus, there are two distinct forms of adult of each sex, one very active in its behaviour and can fly, while the other is of rather dark body colour and cannot fly.About:

Physiology and ecology of dispersal polymorphism in insects
Anthony J. Zera,Robert F. Denno +1 more
TL;DR: Comparative data on wing-dimorphic insects provide the most definitive evidence to date that habitat persistence selects for reduced dispersal capability and the increased fecundity of flightless females documents that a fitness trade-off exists between flight capability and reproduction.
Journal ArticleDOI
The evolution of wing dimorphism in insects
TL;DR: A review of the literature indicates that the presence or absence of wings may be controlled by a single locus, two‐allele genetic system or a polygenic system, and both types of inheritance can be subsumed within a general threshold model.
Journal ArticleDOI
Density-dependent physiological phase in insects.
Shalom W. Applebaum,Yael Heifetz +1 more
TL;DR: Insects respond to crowding in a variety of ways that are usually exemplified by rapid changes in behavior and culminate in enduring long-term morphological and/or chromatic responses, which are dependent not only on density but also on the duration and on phase history of the maternal generation.

Density-Related Migration in Planthoppers (Homoptera: Delphacidae): The Role of Habitat Persistence
TL;DR: Habitat persistence has played a major role in shaping patterns of migration in this group of sap-feeding herbivores by selecting for habitat escape and dictating the availability of mates.
Journal ArticleDOI
Expanding population edges: theories, traits, and trade-offs.
TL;DR: The characteristics of expanding range margins are reviewed and possible mechanisms for the appearance of phenotypic differences between individuals at the leading edge and core of the range are highlighted.

Genetic assimilation of an acquired character
TL;DR: The purpose of the present communication is to describe an experiment in which the hypothesis that if an animal is subjected to unusual circumstances to which it can react in an adaptive manner, the development of the adaptive character might itself become so far canalised that it continued to appear even when the conditions returned to the previous norm.

Phase transformation in locust biology
TL;DR: There is evidence that phase gregaria locusts are more adult and less vegetative than solitaria, not only behaviourally and morphologically but also in their lesser fecundity and longevity.

The specific Status of Callosobruchus maculatus (F.) and Callosobruchus analis (F.)
TL;DR: Two of the species in Callosobruchus, C. maculatus (F.) and C. analis (F.), are compared and redescribed, together with a description of the male and female genitalia of both species.

Observations on an Abnormal Form of Callosobruchus maculatus (F.)
TL;DR: In this article, it was found that the active female was found to have immature ovaries on emergence and these did not develop to any great extent in the conditions employed, and about three-quarters of the active females never produce any eggs, and the rest produce an average of seven.
'Phase' dimorphism observed in the laboratory population of the cowpea weevil, Callosobruchus quadrimaculatus.
TL;DR: The cowpea weevil, Callosobruchus quadrimaculatus, has two distinctly different forms in the adult stage, fly and non-fly forms, which are induced by the effect of population in the larval stage.
