“…Generally, mating pairs needed approximately twice the amount of copulation time to produce a similar number of eggs at the lower temperatures. Males appeared to experience physical diffi culty in transferring sperm when they were raised and mated at low temperatures, as has been shown for other insects (Horton et al, 2002;Katsuki and Miyatake, 2009). Total egg production and the length of the oviposition period of females also increased as the mating duration increased, consistent with other phytoseiid species (Amano and Chant, 1978b;Schulte et al, 1978;Momen, 1993;Tsunoda and Amano, 2001).…”

Sperm transfer during the mating process and subsequent egg production were observed in a predaceous mite species, Neoseiulus californicus, at 18, 25, 30, and 35°C with a photoperiod of 16L:8D. Mating was disrupted at predetermined time points, and female egg production was counted daily. In addition, other females were allowed to mate repeatedly with new males throughout the oviposition period, and egg production was observed. To quantify the volume of sperm transferred from males to females, mated females were sacrificed and mounted immediately after copulation, and the diameter of the spermatophore within the female spermatheca was measured. The results indicated that both sperm volume and egg production increased with mating duration at all temperatures. However, the engorgement of female spermatheca by a spermatophore and subsequent female egg production began at an earlier stage of copulation (after a shorter mating duration) under higher temperatures. Multiple-mated females often had more than one spermatophore in their spermatheca, which was never observed in single-mated females, and the former laid more eggs than the latter at all temperatures. However, total egg production by multiple-mated females did not differ at 25, 30, and 35°C. The reproductive characteristics of N. californicus and their signifi cance to the mite's life history are discussed from the perspective of biological control of one of their primary prey species, spider mites.

“…However, persistent carry-over effects of exposure to hot temperature at early life-stages do not always occur (Huey et al 1995;Potter et al 2011;Xing et al 2014). Exposure to high temperatures during the adult stage may also limit mating performances (Katsuki and Miyatake 2009;Mironidis and Savopoulou-Soultani 2010), egg maturation (Berger et al 2008) and oviposition pattern (Berger et al 2008;Zhang et al 2013), which in turn could alter the temperature effects during early life-stages.…”

Stage-specific heat effects: timing and duration of heat waves alter demographic rates of a global insect pest

The frequency and duration of periods with high temperatures are expected to increase under global warming. Thus, even short-lived organisms are increasingly likely to experience periods of hot temperatures at some point of their life-cycle. Despite recent progress, it remains unclear how various temperature experiences during the life-cycle of organisms affect demographic traits. We simulated hot days (daily mean temperature of 30 °C) increasingly experienced under field conditions and investigated how the timing and duration of such hot days during the life cycle of Plutella xylostella affects adult traits. We show that hot days experienced during some life stages (but not all) altered adult lifespan, fecundity, and oviposition patterns. Importantly, the effects of hot days were contingent on which stage was affected, and these stage-specific effects were not always additive. Thus, adults that experience different temporal patterns of hot periods (i.e., changes in timing and duration) during their life-cycle often had different demographic rates and reproductive patterns. These results indicate that we cannot predict the effects of current and future climate on natural populations by simply focusing on changes in the mean temperature. Instead, we need to incorporate the temporal patterns of heat events relative to the life-cycle of organisms to describe population dynamics and how they will respond to future climate change.

“…Hence, we hypothesize that the higher thermal sensitivity of obligatorily outcrossing lines may be associated with mating failure. Temperature is well-known to affect behavior of ectotherms (reviewed by Angiletta 2009) including reproductive behavior in many species (Wilkes 1963;Linn and Campbell 1988;Katsuki and Miyatake 2009). Whereas self-fertilization is a purely physiological process, outcrossing requires a complex set of behaviors in C. elegans.…”

The maintenance of males and outcrossing is widespread, despite considerable costs of males. By enabling recombination between distinct genotypes, outcrossing may be advantageous during adaptation to a novel environments and if so, it should be selected for under environmental challenge. However, a given environmental change may influence fitness of male, female, and hermaphrodite or asexual individuals differently, and hence the relationship between reproductive system and dynamics of adaptation to novel conditions may not be driven solely by the level of outcrossing and recombination. This has important implications for studies investigating the evolution of reproductive modes in the context of environmental changes, and for the extent to which their findings can be generalized. Here, we use Caenorhabditis elegans – a free-living nematode species in which hermaphrodites (capable of selfing but not cross-fertilizing each other) coexist with males (capable of fertilizing hermaphrodites) – to investigate the response of wild type as well as obligatorily outcrossing and obligatorily selfing lines to stressfully increased ambient temperature. We found that thermal stress affects fitness of outcrossers much more drastically than that of selfers. This shows that apart from the potential for recombination, the selective pressures imposed by the same environmental change can differ between populations expressing different reproductive systems and affect their adaptive potential.
