“…The effect of heat shock on reproductive performance in insects has been widely reported. In T. castaneum, most of the studies were focused on the fecundity, fertility, and progeny production at temperatures of 44-501C (e.g., Saxena et al, 1992;Arbogast, 1981;Mahroof et al, 2005a). Howe (1965) revealed that 401C is the upper physiological limit for T. castaneum.…”

Heat shock affects reproductive performance in insects including Tribolium castaneum. In this study, the effects of heat shock on ovary development and hsp83 expression in T. castaneum were investigated. Two lines of T. castaneum, H line and C line, from the same base population were established and maintained for five successive generations. In each generation, the newly hatched beetles (within 3 h after eclosion) in the H line were treated with a heat shock at 40 degrees C for 1 h, and those in the C line were raised at normal temperature (30 degrees C) as control treatment. Four traits related to ovary development were measured for the beetles of the fifth generation: days from eclosion to laying the first eggs (T(o)), days from eclosion to laying the first hatchable eggs (T(h)), ovariole size on the third day after eclosion, and pupal mass of their offspring. The results showed that the beetles of the H line had a significantly longer pre-oviposition period (0.6 more days) and smaller ovariole size than those of the C line. No significant difference in pupal mass was observed. Applying heat shock to the offspring of the fifth generation of both lines led to significantly higher hsp83 expression in offspring of the C line than in offspring of the H line. Within each line, the hsp83 expression level in offspring with heat shock was significantly higher than that of offspring without heat shock, but the difference in the C line was much larger than that in the H line. We infer from these results that a tradeoff between heat resistance, registered as hsp83 expression, and ovarian development operates under heat stress in T. castaneum.

“…Previous studies have shown that a major effect of heat shock on male fecundity is direct injury to the sperm (Saxena et al, 1992). Thus, we might expect the aforementioned effects on male fertility to be further demonstrated by reduced sperm viability or the inability to transfer sperm to the female.…”

“…Lethality can occur immediately, as documented for several insects of economic importance (Armstrong, 1992;Hansen, 1992), or as a result of a failure to complete development at a later stage as observed in Sarcophaga crassipalpis and Drosophila melanogaster (Mitchell & Lipps, 1978). Sublethal effects, such as decreased longevity (Chihrane et al, 1993), wing deformation (Milkman, 1962) and a decrease in fertility (Arbogast, 1981), especially by sterilization of males (Saxena et al, 1992), are also frequently noted in heat-stressed insects. Exposure to low temperatures can be equally detrimental (Denlinger & Lee, 1998), leading to delayed mortality (Bale et al, 1989), nervous system impairment (Yocum et al, 1994) and reduced fecundity caused by egg mortality (Coulson & Bale, 1992).…”

Abstract. Although the immediate effects of temperature stress are well documented, the longer-term effects of such stresses are more poorly known. In these experiments, we investigate the effects of suboptimal and supraoptimal temperatures during pharate adult development on fecundity in the¯esh¯y, Sarcophaga crassipalpis Macquart. A 1 h cold shock at ±10°C during the red-eye pharate adult stage decreases the fecundity of both sexes. Induction of rapid cold hardening by pre-treatment at 0°C for 2 h partially prevents reproductive impairment. Heat shock of pharate adults for 1 h at 45°C also reduces fecundity in both sexes, but inducing thermotolerance by pre-treatment at 40°C for 2 h affords protection only to females. Males heat shocked at 45°C or ®rst pre-treated at 40°C consistently fail to transfer sperm to the females. The injury in¯icted on males by heat shock is most pronounced when the stress is administered to pharate adults or adults; wandering larvae and true pupae are unaffected. The implications of these data for naturally occurring populations are discussed.

“…Several studies have shown that insects surviving exposure to sublethal high temperatures may exhibit impaired development, hatching rhythm, morphology, longevity, fecundity, fertility and over-all fitness; damage results from temperature exposure (Proverbs and Newton, 1962;Gonen, 1977;Arbogoast, 1981;Saxena et al, 1992;Mahroof et al, 2005aMahroof et al, , 2005bJØrgensen et al, 2006;Xie et al, 2008;Cui et al, 2008;Niedermayer et al, 2013). Among traits currently known to be affected by heat stress, reproductive processes are often diminished by less severe conditions than those causing mortality (Fasolo and Krebs, 2004;Walsh et al, 2019).…”

In insects, decreased reproduction is a sublethal consequence of high temperatures, with males being more sensitive to this in many species. In hymenoptera, arrhenotokous parthenogenesis means that female offspring are produced using sperm and are thus diploid, while males are haploid. Consequently, sperm stocks in males and females (after copulation) are a key regulator of the sex ratio. Anisopteromalus calandrae is a parasitoid wasp in which males can suffer from subfertility due to a drastic decrease in sperm count after exposure to high temperatures during a critical early pupal stage. However, in this species spermatogenesis continues during adulthood, therefore the heat sensitivity of adult males remains to be studied. Laboratory studies were conducted on virgin and previously mated young adult males under control (30°C) and heat shock (10 min at 48°C) conditions to exhaust their initial sperm stock. After heat shock, in both virgin and already mated males, the individual sperm potential was half that of controls. Both groups continuously produced sperm, but sperm stock of heat shocked males' never reached that of the controls. Heat shock reduced survival at 10 days only in previously experienced males but had no impact on the mating ability in competition for a female compared to controls. Despite a reduced sperm count, heat shocked males had fully fertile spermatozoa. Such a physiological response to heat shock in a species with continuous sperm production could be of major interest for both wild populations in a context of temperature variations and parasitoid wasps introduced for agronomical purposes.
