Finding a mate is a fundamental aspect of sexual reproduction. To this end, specific-mate recognition systems (SMRS) have evolved that facilitate copulation between producers of the mating signal and their opposite-sex responders. Environmental varia

In recent years, investigations into the evolution of sexual size dimorphism have moved from a simple single trait, single sex perspective, to the more robust view of multivariate selection acting on both males and females. However, more accurate pre

We have characterized the process of flight muscle histolysis in the female house cricket, Acheta domesticus, through analysis of alterations of tissue wet weight, total protein content, and percent shortening of the dorsal longitudinal flight muscle

Parasite-mediated sexual selection theory posits that individuals (usually females) choose mates by assessing the expression of costly secondary sexual signals, which provide reliable indications of parasite resistance. If these signals are indeed re

Many factors determine the formation of flight wings in wing-polymorphic insects. Earlier studies on a cricket (Gryllus firmus) population producing spring and summer generations showed a declining frequency of macropterous, or long-winged, adults to

The maintenance of female polyandry has traditionally been attributed to the material (direct) benefits derived from male mating resources (e.g. nuptial gifts) accrued by multiple mating. However, genetic (indirect) benefits offer a more robust expla

Many male insects provide somatic nuptial gifts that may strongly influence reproductive fitness by insuring an effective copulation or by increasing paternal investment. In the striped ground cricket, Allonemobius socius (Scudder), females receive a

The sibling ground crickets Allonemobius fasciatus and A. socius meet along a mosaic hybrid zone at ≈ 40°N latitude in eastern North America. In this paper we report the findings of a genetic analysis of calling-song variation within and among six

For many temperate-zone insects, systematic changes in climate signal the coming of winter and effect changes in behavior and physiology. A late-summer female, for example, that senses a general reduction in temperature, photoperiod, or both may opti

In the ground cricket Allonemobius socius (Scudder 1877), males provide females with a hemolymph-based nuptial gift. The size of the gift depends on when copulation is terminated, which can be controlled by either sex. Here we show that more immunoco
