“…2). Although previous studies show that in some Lepidoptera species mating behaviour and ejaculate production have negative effects on male longevity and mortality rate (Shapiro, 1982;Cordero, 2000;Ferkau & Fischer, 2006;Wedell, 2010;Caballero & Cordero, 2013), our results are not completely novel since in other lepidopterans no negative effects have been found (Svärd, 1985;Oberhauser, 1989;Ferkau & Fischer, 2006;Janowitz & Fischer, 2010;Takeuchi, 2012;Callado-Galindo et al, 2013).…”

“…Previous experimental studies of male mating costs in Lepidoptera show that in some species mating behaviour and ejaculate production negatively affect male longevity and survivorship rate (Shapiro, 1982;Drummond, 1984;Cordero, 2000;Ferkau & Fischer, 2006;Wedell, 2010;Caballero-Mendieta & Cordero, 2013); however, in other species no negative effects have been found (Svärd, 1985;Oberhauser, 1989;Ferkau & Fischer, 2006;Janowitz & Fischer, 2010;Takeuchi, 2012;Callado-Galindo et al, 2013). On the other hand, even in cases where no effect on male survivorship exists, the typical decrease in ejaculate size observed in consecutive copulations of multiple mated males could be costly since ejaculate size tends to be positively correlated with male fitness due to its positive effect on the length of the post-copula period of diminished female sexual receptivity (Sugawara, 1979;Wedell, 2005;Watanabe, 2016) and on female fecundity (Torres-Vila & Jennions, 2005;Duplouy & Hanski, 2015).…”

In some insects, males produce costly ejaculates that reduce the typical sexual imbalance in potential reproductive rates thus influencing the mode and intensity of sexual selection. In Lepidoptera, in particular, males tend to invest heavily in mate searching, courtship and ejaculate production; furthermore, in some species males shed genital spines (deciduous cornuti) within the female genital tract during copulation. We studied experimentally the potential mating costs incurred by males of a moth with deciduous cornuti, Amorbia cuneana (Tortricidae). In the first experiment, we tested the prediction that mating costs result in a reduction in male longevity and survival rate. Our results did not support this prediction because virgin and mated males had similar longevity and survival rate. This result is somewhat surprising considering the substantial resource investment in mating found in the second experiment. In their first mating males invested in the ejaculate 9% of their body weight and transferred virtually all their deciduous cornuti; furthermore, few males were able to mate a second time (although we do not know if this was due to female rejection), these males produced smaller ejaculates and there was no evidence of cornuti regrowth. We hypothesize that reduced mating opportunities have selected for males that are ready to transfer large ejaculates at any moment and thus against the diversion of resources from reproductive tissues to somatic maintenance in unmated males; the transfer of the full set of deciduous cornuti in first copulations is consistent with this hypothesis.

Herbivory insects can discriminate the quality of a host plant for food or oviposition, by detecting the volatile organic compounds (VOC's) released by the plant, however, damaged plants may release a different VOC's profile modifying the insects' response. We tested if the VOC's profile from damaged plants affected the response of Copitarsia decolora as these moths oviposit preferably around undamaged host plants. We assessed the response in wind tunnel conditions of C. decolora mated females to volatiles collected by dynamic headspace from 30-40 d old cabbage undamaged plants and mechanical and larval damaged plants. Headspace volatile compounds from undamaged cabbage plants were more attractive to mated females than those from larval and mechanical damaged cabbage plants. Moths stimulated with headspace volatiles from undamaged plants performed more complete flight and ovipositor displays than those moths stimulated with headspace volatiles from damaged cabbage plants. A mixture of synthetic compounds identified from undamaged cabbages elicited similar antennal and wind tunnel responses in mated females as headspace volatiles from undamaged cabbage plants. C. decolora females may discriminate between damaged and undamaged host plants by detecting their VOC's profiles as a strategy to avoid unsuitable plants for their offspring increasing their fitness.

“…In many invertebrate species, egg fertilization is partly affected by the quantity and quality of sperm and other components of the ejaculate transferred by males (Keller & Reeve, 1995). Both the quality and quantity of sperm may vary over time or in different-quality males as a consequence of the recovery rates and costs associated with its production (Dewsbury, 1982;Rigaud & Moreau, 2004;Bugnot & L opez Greco, 2009;Callado-Galindo et al, 2013;Scharf, Peter & Martin, 2013;Butler, Mac Diarmid & Gnanalingam, 2015;Alavi, Elgar & Jones, 2016). One of the main factors that determine male reproductive quality in some invertebrate species is body size: small males produce lower sperm quantities than larger males and could limit egg fertilization by providing smaller ejaculates to females (e.g.…”

Egg production in relation to paternal weight in a freshwater caridean shrimp (Decapoda)

In diverse invertebrate species, sperm quantity and quality are positively correlated with male size, egg fertilization rates being consequently affected by paternal weight. This factor may also have an indirect effect on egg quality, because females could adjust the quantity of yolk stored in oocytes before spawning according to their partner attractiveness. The objective of this study was to determine whether paternal weight influences egg production in a freshwater crustacean with external egg fertilization, the caridean shrimp Neocaridina davidi. Virgin females weighing 60–100 mg were paired with virgin males weighing 20–50 mg. The number (total and fertilized), size (volume, wet and dry weight) and carotenoid content of eggs were recorded for each pair. Paternal weight was not associated to any of the evaluated egg variables, while maternal weight showed a positive correlation with egg number and a negative correlation with egg carotenoid content. The percentage of fertilized eggs was similar and near 100% for all paternal sizes, which indicates that small mature males provided enough good‐quality sperm to fertilize almost all the oocytes laid by females, similarly to larger males. The relatively low fecundity of N. davidi females may explain, at least in part, the absence of sperm limitation even under a hypothetical decrease in sperm supply by smaller males. In addition, paternal weight had no effect on egg volume, weight and carotenoid content, which suggests that females do not modulate the total amount of biochemical reserves allocated to the maturing ovary as a function of their partner size. Present results are the starting point for a future evaluation of sperm production, in terms of quantity and quality, in males of different size and physiological condition.
