“…ULCIZ values are almost similar, ranging from 9–10 °C, among all tested SHB stages, which shows that above this range no chilling mortality will occur. However, there was no survival at 13 °C based on our previous developmental study [ 26 ]. This failure of development may link to the incomplete blockade of morphogenetic processes.…”

“…Being ectothermic, temperature greatly influences the development and survival of SHB in Korea, as we demonstrated in our previous study [ 26 ]. Winter survival is an important predictor of an invasive species to become established and to extend its range limits in temperate regions [ 3 ].…”

“…However, there are still possibilities when SHB feeding larvae can be exposed to lethal cold temperatures. In our previous study [ 24 ], we reported that SHB can continue reproduction at the temperature of winter bee’s cluster (20 °C), so feeding larvae still can be exposed to winter temperatures in the brood-less area or peripheral portion of the hives. Colony loss, especially near winter season, may force SHB adults to lay eggs outside the hives near rotten fruits, which are alternative food sources [ 25 ] for their feeding larvae.…”

“…After three to six days of feeding, third instar larvae stop feeding and move out of the hive as wandering larvae, regardless of the season, to find a suitable substrate (mostly soil) for pupation. Wandering larvae make pupal chambers after finding substrate and turned into pupae after spending 10 days in a pupal chamber at 25 °C [ 26 ]. The pupae take eight days in that substrate to become adults at 25 °C.…”

The small hive beetle (SHB) Aethina tumida Murray, (Coleoptera: Nitidulidae) is now a global invasive pest of honey bees, but its cold tolerance potential has not been yet explored. Therefore, we measured the supercooling point (SCP) of different stages of SHBs and also the impact of acclimation on their SCPs and survival as a measure for cold tolerance. Combinations of different temperatures (0, 3, 5, 7, and 10 ∘C) for different hours (1, 3, 5, 7, 12, 24, 35, and 48 h) were used to assess SHB survival. The supercooling points occurred at lower temperatures (−19.4 ∘C) in wandering larvae than in the other stages (pupae: −12.5 ∘C, and feeding larvae: −10.7 ∘C). A lethal temperature (LT50) of feeding larvae was achieved earlier at 4.9 ∘C after 7 h exposure than the wandering larvae (3.7 ∘C at 48 h) and pupae (5.6 ∘C at 48 h). The sum of injurious temperature (SIT) is the most suitable estimation to describe cold resistance of the SHB immatures. The wandering larvae were the most cold tolerant, followed by pupae and feeding larvae based on SIT values of −286.8, −153.7 and −28.7 DD, respectively, and also showed more phenotypic plasticity after acclimation than feeding larvae and slightly more than pupae. Our results show that all stages, i.e., feeding larvae, wandering larvae and pupae, are chill susceptible. However, these stages, especially wandering larvae and pupae, showed the capacity to acclimate to cold temperatures, which may help them to survive in winter for the continuity of the SHB population, especially in a scenario of climate change.

Limited sex differences in plastic responses suggest evolutionary conservatism of thermal reaction norms: A meta-analysis in insects

et al. 2022

Temperature has a profound effect on the growth and development of ectothermic animals. However, the extent to which ecologically driven selection pressures can adjust thermal plastic responses in growth schedules is not well understood. Comparing temperature‐induced plastic responses between sexes provides a promising but underexploited approach to evaluating the evolvability of thermal reaction norms: males and females share largely the same genes and immature environments but typically experience different ecological selection pressures. We proceed from the idea that substantial sex differences in plastic responses could be interpreted as resulting from sex‐specific life‐history optimization, whereas similarity among the sexes should rather be seen as evidence of an essential role of physiological constraints. In this study, we performed a meta‐analysis of sex‐specific thermal responses in insect development times, using data on 161 species with comprehensive phylogenetic and ecological coverage. As a reference for judging the magnitude of sex specificity in thermal plasticity, we compared the magnitude of sex differences in plastic responses to temperature with those in response to diet. We show that sex‐specific responses of development times to temperature variation are broadly similar. We also found no strong evidence for sex specificity in thermal responses to depend on the magnitude or direction of sex differences in development time. Sex differences in temperature‐induced plastic responses were systematically less pronounced than sex differences in responses induced by variations in larval diet. Our results point to the existence of substantial constraints on the evolvability of thermal reaction norms in insects as the most likely explanation. If confirmed, the low evolvability of thermal response is an essential aspect to consider in predicting evolutionary responses to climate warming.
