Costs and benefits of acclimation to elevated temperature in Trichogramma carverae

Abstract: The consequences of acclimation for survival and other fitness components in the parasitoid wasp, Trichogramma carverae (Oatman and Pinto), were examined. Heat hardening adult wasps at 33 °C or 35 °C for one to two h increased survivorship at 40 °C. This benefit was apparent for several hours after heat‐hardening and occurred in both males and females. Heat hardening at 33 °C during development also resulted in significant increases in survivorship of adults after exposure to 40 °C. However, this developmental… Show more

“…A negative correlation between temperature and fecundity has been repeatedly reported in many parasitoids (Sorokina 1978;Zaslavskiy and May Phu Qui 1982;Atamirzaeva 1991;Pavlik 1992;Scott et al 1997;Wang and Ferro 1998). In our findings, fecundity of parasitoids was considerably reduced due to high temperature shocks, in congruence with earlier reports on Trichogramma species (Calvin et al 1984;Chihrane et al 1993;Chihrane and Lauge 1996;Reznik et al 1997;Maisonhaute et al 1999;Singh and Ram 2006;Reznik and Vaghina 2006a, b;Ayvaz et al 2008).…”

“…2b) will likely lead to incorrect predictions of how the population will respond to climate change or to habitat shift (see Dunham 1993;Huey and Kingsolver 1993;Lynch and Lande 1993). Similarly, using inappropriate data might also encourage applied biologists to choose nonoptimal thermal regimes for rearing organisms for release as biocontrol agents (Yang et al 1994;Scott et al 1997). Recall that the optimal temperature for r averages 4.9ЊC higher than that for R o .…”

“…When temperature exceeds the favorable temperature range of an insect species, it will cause death, and even if a species does survive exposure to extremely high temperature, its fitness will be affected (Yocum & Denlinger 1992;Scott et al 1997;Rinehart et al 2000). Our results indicated that there was no immediate influence on the survival rate of female western flower thrips exposed to 41 °C for different durations.…”
