“…If neighboring females interfere with a focal female's mating efforts, selection toward earlier calling can intensify in a manner analogous to earlier arrival of migratory organisms when the number of competitors increases (Kokko et al 2006). Although many empirical studies have measured the percentage of females calling (e.g., Webster and Cardé 1982;Babilis and Mazomenos 1992;Kamimura and Tatsuki 1993;Ming et al 2007), more information on their spatial arrangement could prove useful. Females can potentially use cues other than their own mating status to adjust signaling effort: if females can perceive the signals of competing females, there is potential for more complex signaling strategies than the ones modeled by us (Harari et al 2011).…”

“…Further, obviously all of these factors can be strongly influenced by the weather and climate (McNeil 1991;Pellegrino et al 2013), and mate-searching males are known to navigate pheromone plumes of rather complex filamentous structure (e.g., Liu and Haynes 1992). Females can simply modify male arrival rates by choosing not to call (e.g., after mating; Webster and Cardé 1984). Here we do not focus on the postmating response, since it may be influenced by either male manipulation of female receptivity or the females' choices.…”

“…Increasing calling rate with age may be a behavioral strategy for older females to cope with a physiologically driven decline in pheromone production (Webster and Cardé 1982;Delisle and Royer 1994;Mazor and Dunkelblum 2005). Unfortunately, data for both traits together exist for only 12 species in 13 studies (table 1).…”

Although females rarely experience strong mate limitation, delays or lifelong problems of mate acquisition are detrimental to female fitness. In systems where males search for females via pheromone plumes, it is often difficult to assess whether female signaling is costly. Direct costs include the energetics of pheromone production and attention from unwanted eavesdroppers, such as parasites, parasitoids, and predators. Suboptimal outcomes are also possible from too many or too few mating events or near-simultaneous arrival of males who make unwanted mating attempts (even if successfully thwarted). We show that, in theory, even small costs can lead to a scenario where young females signal less intensely (lower pheromone concentration and/or shorter time spent signaling) and increase signaling effort only as they age and gather evidence (while still virgin) on whether sperm limitation threatens their reproductive success. Our synthesis of the empirical data available on Lepidoptera supports this prediction for one frequently reported component of signalingtime spent calling (often reported as the time of onset of calling at night)-but not for another, pheromone titer. This difference is explicable under the plausible but currently untested assumption that signaling earlier than other females each night is a more reliable way of increasing the probability of acquiring at least one mate than producing a more concentrated pheromone plume.

“…If mating is delayed, the germ cells within the germarium disorganize and cell death occurs (Berger and Cruz-Landim 2012;. In several insects, mating is the primary factor that triggers oocyte ripening in the ovary, indicating the presence of factors in seminal fluid that trigger oogenesis (Ando et al 1996;Coffelt and Vick 1987;Fan et al 1999;Foster 1993;Giebultowicz et al 1991;Rafaeli and Gileadi 1995;Raina et al 1994;Shorey et al 1968;Webster and Carde 1984). Nonetheless, when analyzing mucus gland secretions, which are introduced with semen into the genital tract of honey bee queens, Colonello and Hartfelder (2003) did not find evidence that drone accessory gland proteins are necessary for ovarian development in A. mellifera .…”

Beekeeping practice: effects of Apis mellifera virgin queen management on ovary development

2015

-Newly emerged virgin queens are frequently imprisoned in cages either inside or outside of colonies before delivery to a new hive. Ovary integrity and proper functioning is the primary factor in a queen's success as the colony mother. In this work, histological studies on ovaries are used to evaluate the effect of virgin queen imprisonment both out and inside the colony. The results show that the ovarian follicles of virgin queens maintained out of the colony advance only until the beginning of differentiation of oocytes and nurse cells, the vitellarium does not differentiate, and cell death is observed. For virgin queens caged inside a colony, oogenesis progresses until nurse cell and oocyte differentiation is completed, and the vitellarium shows initial differentiation. The results suggest that the best method for a head start of a queen's fertility is to maintain her inside the colony until introduction into a new hive.apiculture / caged queen / cell death / egg production / histology

“…Chemical substances which affect behavior of insects following mating have been found in a lepidopteran (Webster & Carde, 1984); an ichneumon wasp, Venturia (Nemeritis) canescens (Gravenhorst) (where heneicosane was involved) (Mudd et al, 1982) ; and the dipteran Drosophila, involving enzymes (Mane et al, 1983 ;Richmond & Senior, 1981). Prostaglandins, derivatives of certain polyunsaturated fatty acids, alter egg laying behavior in crickets (Stanley-Samuelson & Loher, 1986).…”
