Nuptial food gifts given by males to females at mating are widespread in insects, but their evolutionary origin remains obscure. Such gifts may arise as a form of sensory trap that exploits theExpand

A dynamic threshold model for terminal investment
Although reproductive strategies can be influenced by a variety of intrinsic and extrinsic factors, life history theory provides a rigorous framework for explaining variation in reproductive effort.Expand

Females use self-referent cues to avoid mating with previous mates
Females of many species mate repeatedly throughout their lives, often with many different males (polyandry). Females can secure genetic benefits by maximizing their diversity of mating partners, andExpand

Ejaculate expenditures of male crickets in response to varying risk and intensity of sperm competition: not all species play games
Costs incurred in the manufacture of ejaculates may constrain the number of sperm that males can produce, so males should show some economy in their allocation of sperm across multiple matings. InExpand

Courtship feeding in decorated crickets: is the spermatophylax a sham?
Abstract Abstract. The spermatophore transferred by a male decorated cricket, Gryllodes sigillatus , at mating includes a large gelatinous spermatophylax, devoid of sperm, which the female removesExpand

Cryptic Sexual Conflict in Gift‐Giving Insects: Chasing the Chase‐Away
The chase‐away model of sexual selection posits that elaborate male sexual displays arise because they exploit preexisting biases in females’ sensory systems and induce females to mate in aExpand

REPRODUCTIVE BEHAVIOUR OF THE
Male crickets (Orthoptera: Gryllidae) compete for females through direct physical aggression (ALEXANDER, 1961; BURK, 1983; BOAKE, 1984; DIXON & CADE, 1986) and acoustic signalling behaviourExpand

POLYANDRY PROMOTES ENHANCED OFFSPRING SURVIVAL IN DECORATED CRICKETS
Abstract Although female multiple mating is ubiquitous in insects, its adaptive significance remains poorly understood. Benefits to multiple mating can accrue via direct material benefits, indirectExpand

Spermatophore size and its role in the reproductive behaviour of the cricket, Gryllodes supplicans (Orthoptera: Gryllidae)
The spermatophore that a male cricket of Gryllodes supplicans transfers to the female during mating, includes a large gelatinous portion (spermatophylax) that is removed and consumed by the female ...

Experimentally induced spermatophore production and immune responses reveal a trade-off in crickets
The energetic demands of the immune system and reproduction are often high and can lead to trade-offs between these 2 life-history traits. In decorated crickets, Gryllodes sigillatus, much of aExpand
