The physiological costs of flight capability in wing‐dimorphic crickets

Population Ecology, 1994
AbstractNutritional indices, triglyceride levels and flight muscle developmental profiles were compared between long‐winged (LW) and short‐winged (SW; flightless) morphs of the crickets Gryllus rubens Scudder and G. firmus Scudder. This was done to identify potential physiological costs of flight capability in adults.

Variation in fighting strategies in male wing-dimorphic crickets (Gryllidae)

Behavioral Ecology and Sociobiology, 2016
Because a trade-off between reproduction and dispersal has been commonly found in wing-dimorphic insects, males of different wing morphs may have a different demand on a mate or a territory. We hypothesized that males of wing-dimorphic insects may vary in fighting success over these two resources.

Why is there so much genetic variation for wing dimorphism?

Population Ecology, 1994
AbstractWing dimorphism appears in general to be determined either by a single locus, 2 allele system in which brachyptery is dominant, or by the additive action of numerous loci. In the latter case studies indicate that the heritability is typically quite large.

Habitat Persistence and the Evolution of Wing Dimorphism in Insects

The American Naturalist, 1994
Wing dimorphism occurs commonly among many species of insects. This dimorphism is hypothesized to be maintained by a trade-off between the costs of being macropterous (winged, flight capable) and the long-term benefits of migration in a heterogeneous environment.

Role of monoamine metabolism in wing dimorphism of the aphid Myzus persicae

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1976
Abstract 1. 1. Wing dimorphism of the aphid Myzus persicae which normally is regulated by a number of exogenic factors can be influenced by neuropharmaca. 2. 2. With micro-injections of drugs that are known to act on monoamine metabolism it is possible to direct the course of development towards the alate or apterous morph. 3.

Wing Dimorphism and Diapause in Gerris: Determination and Adaptive Significance

1978
Water-striders of the genus Gerris Fabr. consist of a small group of predatory bugs living on the water surface. In temperate climates the habitats often freeze in the winter, and gerrids overwinter on dry land as imagos. The morphology of the species restricts them to habitats protected from wave action.
