Mating produces profound changes in the behavior of female flies, such as an increase oviposition, reduction sexual receptivity, feeding, and even excretion. Many these are produced by copulation, sperm, accessory gland products that males transfer to females during mating. Our knowledge on function male ejaculate its effect insects is still incipient. In this article, we review peri- postcopulatory behaviors tephritid flies. We address effects copulatory behavior; copula duration; ejaculate, remating behavior. species from families pests economic importance; thus, understanding mating contributes both developing more effective environmentally friendly control methods furthering our evolutionary implications intersexual competition conflict.

Seminal fluid proteins (Sfps) modify female phenotypes and have wide-ranging evolutionary implications on fitness in many insects. However, the Mexican fruit fly, Anastrepha ludens , a highly destructive agricultural pest, functions of Sfps are still largely unknown. To gain insights into regulated by Sfps, we used nano-liquid chromatography mass spectrometry to conduct proteomic analysis soluble from reproductive organs A. . The predicted be transferred males females during copulation were 100 accessory glands, 69 testes 20 ejaculatory bulb, resulting 141 unique after accounting for redundancies multiple tissues. These included orthologues Drosophila melanogaster involved mainly oogenesis, spermatogenesis, immune response, lifespan fecundity. In particular, found one protein associated with olfactory response repellent stimuli (Scribble), two related memory formation (aPKC Shibire). Together, these results raise possibility that could play role regulating responses indicative novel this important pest.

Mating and the transfer of seminal fluid components including male accessory glands (MAGs) proteins can affect oviposition behavior in insects. After oviposition, some species fruit flies deposit a host-marking pheromone (HMP) on that discourages by other females same or different genus reduces competition between larvae. However, we know very little about how mating, receiving fluid, condition female host marking behavior.

However, most animals, while makes up only a small portion seminal fluid, males also have complex mixture proteins, peptides, different types noncoding RNAs, cell-free DNA fragments their ejaculate. These fluid contents (Sfcs) are close contact with reproductive cells, tissues, organs, other molecules both females during reproduction. Moreover, production use adjusted response to environmental conditions, making them potential markers environmentally- developmentally-induced effects on next generation(s). Although there some intriguing for Sfc-mediated effects, underlying molecular mechanisms remain poorly defined. In this review, current regarding links between pathways may follow discussed.
