The contingency of fitness: an analysis of food restriction on the macroptery–reproduction trade-off in crickets

Animal Behaviour, 1998
We examined the effect of food limitation on fitness trade-offs between macroptery and time spent calling in the wing-dimorphic cricket, Gryllus firmus. The results of previous studies have shown that, under optimal conditions, the proportionate time that males spend calling (with respect to neighbouring males) is directly associated with female ...

Seasonal abundance of macropterous Nilaparvata lugens and Sogatella furcifera based on presumptive macroptery in fifth‐instar nymphs

Ecological Entomology, 1985
Abstract. 1. The seasonal changes in abundance of macropterous N. lugens (Stal) and S. furcifera (Horvath) (Homoptera: Delphacidae) are described based on observed numbers of adults and presumptive macroptery in fifth‐instar nymphs occurring in rice crops in the Philippines ...

Environmental factors inducing macroptery in the psocid Psoquilla marginepunctata

Entomologia Experimentalis Et Applicata, 1987
AbstractWhen subjected to high population densities, Psoquilla marginepunctata (Hagen) produced more macropterous females than males. This sex ratio bias was due to the greater sensitivity of female nymphs to crowding. About 50% of the female nymphs, subjected to crowding up to the end of the 4th instar and later, developed into marcropterous adults ...

A New Species of Myrmecoderus Aalbu, Andrews and Pollock (Coleoptera: Salpingidae: Dacoderinae) from Mexico, with a Key to the Species and Comments on Macroptery in the Genus

The Coleopterists Bulletin, 2020
Myrmecoderus veracruzensisnew species, from the tropical deciduous forest of the municipality of Xalapa, Veracruz, Mexico, is described and illustrated. A key to the species of this genus is included. Comments on macroptery in the subfamily Dacoderinae of the New World are given, and a new state record is given for Dacoderus werneri Aalbu, Andrews and ...

Life-history trade-off between macroptery and reproduction in the wing-dimorphic pygmy grasshopperTetrix subulata(Orthoptera Tetrigidae)

Ethology Ecology & Evolution, 2014
Dimorphism in wing length is well known in many insect species. In those species a trade-off exists between dispersal capability and reproduction, with the long-winged (LW) morph being a better disperser due to superior flight capability. The short-winged (SW) morph is less mobile and it is hypothesised that females of this morph can invest more energy
