“…Such a relationship between body size and heat resistance is documented both for vertebrates 63 and arthropods 9,64,65 . Consequently, extreme high temperatures should favor individuals reaching larger size at maturity 66 , which is empirically supported by few studies indicating WGP responses to heat stress 9,60,67,68 . Based on these considerations, we assume that the TGP effects in A. limonicus should increase the female heat resistance by large size.…”

Heat waves are considered to pose a greater risk to arthropods with their limited thermoregulation abilities than the increase of mean temperatures. Theoretically, within- and trans-generational modifications may allow populations to keep pace with rapidly occurring heat waves. Here, we evaluated this assumption using individuals of predatory mite Amblydromalus limonicus from the F1 and F2 generation, which were exposed to summer or simulated heat wave conditions during juvenile development. Independent of generation, survival and male body size were insensitive to heat waves. Heat stress elongated juvenile development of F1 males and females, and lowered the F1 female size at maturity indicating non-adaptive within-generational effects. Trans-generational modifications speeded up the development of F2 males and females and resulted in larger body size of F2 females deriving from the heat wave-experienced F1 generation. Faster F2 development should be adaptive, because it reduces the exposure time to heat waves and promotes an early beginning of mating activities. Being large at extreme high temperatures maybe a benefit for the F2 females, because large individuals are less vulnerable to dehydration and overheating. Thus, the potential fitness loss from reduced F1 growth should be compensated by increased fitness in the F2 indicating adaptive trans-generational modifications.

“…Interestingly, most of the exceptions to the rule are reported in insects, most commonly in Ephemeroptera, Orthoptera and Lepidoptera (Atkinson, ; Willott & Hassall, ; Kingsolver et al ., ). For example, reversals of the TSR are found in four species of mayfly (Atkinson, ), four species of British grasshoppers (Willott & Hassall, ), the North Carolina population of small cabbage white Pieris rapae (from the central Piedmont region near Chapel Hill, North Carolina) (Kingsolver et al ., ), the tobacco hornworm Manduca sexta when reared on a low‐quality host (Diamond & Kingsolver, ), the corn earworm Helicoverpa zea (Clemmenden & Hahn, Clemmensen & Hahn, ) and the rice stem borer Chilo suppressalis (Fu et al ., ). However, selection mechanism for the TSR and the reverse‐TSR still remains unclear.…”

A reverse temperature‐size rule associated with a negative relationship between larval development time and pupal weight in a tropical population of Ostrinia furnacalis

Empirical studies demonstrate a negative relationship between body size and temperature [i.e. the temperature-size rule (TSR)] and a positive relationship between body size and development time (a trade-off). However, many exceptions are also reported. The present study tests the two relationships in a tropical population of the Asian corn borer Ostrinia furnacalis under a wide range of temperatures from 18 to 31 ∘ C. The results show that larval time is decreased significantly and pupal weight is increased significantly with an increasing rearing temperature, exhibiting the reverse-TSR. Growth rate is positively correlated with temperature. The relationships between body size and development time among individuals show a negative slope (i.e. pupal weight tends to decrease with increases in development time). Females are significantly larger than males at all temperatures, showing a female-biased sex size dimorphism. It is also found that development time and pupal weight vary greatly among individuals, particularly at lower temperatures. The results of the present study demonstrate a reverse-TSR associated with a negative relationship between larval development time and pupal weight in a tropical population of O. furnacalis.

“…However, increasing evidence has shown that the reverse TSR in insects is also common. For example, reversals of the TSR have been found in four species of mayfly (Atkinson, ); four species of British grasshoppers (Willott & Hassall, ); the tropical butterfly, Bicyclus anynana (Fischer, Bot, & Brakefield, ); the small cabbage white, butterfly, Pieris rapae (Kingsolver, Massie, Ragland, & Smith, ); the Asian corn borer, Ostrinia furnacalis (He, Tang, Huang, Gao, & Xue, ; Xiao et al, ); and the rice stem borer, Chilo suppressalis (Fu, He, Zhou, Xiao, & Xue, ; Huang, Xiao, He, & Xue, ). As such, why do some insect species follow the TSR and some exhibit the reverse TSR?…”

“…Those species with summer diapause may exhibit the TSR, as indicated by the cabbage beetle, C. bowringi (Tang, He, Chen, Fu, & Xue, ) and this butterfly, P. melete because their reproductive periods occur in the spring and autumn and because these insects have experienced strong selection for body size under relatively low environmental temperatures during the process of evolution. Those species with winter diapause triggered by shortening day lengths combined with high autumn temperatures may exhibit the reverse TSR, as indicated by the Asian corn borer, O. furnacalis (He et al, ; Xiao et al, ), and the rice stem borer, C. suppressalis (Fu et al, ; Huang et al, ). These two species enter winter diapause in response to high autumn temperatures and experience strong selection for body size under warm conditions.…”

The seasonal life cycle of the cabbage butterfly, Pieris melete is complicated because there are three options for pupal development: summer diapause, winter diapause, and nondiapause. In the present study, we tested the influence of temperature, day length, and seasonality on the expression of alternative developmental pathways and compared the differences in life history traits between diapausing and directly developing individuals under laboratory and field conditions. The expression of developmental pathway strongly depended on temperature, day length, and seasonality. Low temperatures induced almost all individuals to enter diapause regardless of day length; relatively high temperatures combined with intermediate and longer day lengths resulted in most individuals developing without diapause in the laboratory. The field data revealed that the degree of phenotypic plasticity in relation to developmental pathway was much higher in autumn than in spring. Directly developing individuals showed shorter development times and higher growth rates than did diapausing individuals. The pupal and adult weights for both diapausing and directly developing individuals gradually decreased as rearing temperature increased, with the diapausing individuals being slightly heavier than the directly developing individuals at each temperature. Female body weight was slightly lower than male body weight. The proportional weight losses from pupa to adult were almost the same in diapausing individuals and in directly developing individuals, suggesting that diapause did not affect weight loss at metamorphosis. Our results highlight the importance of the expression of alternative developmental pathways, which not only synchronizes this butterfly's development and reproduction with the growth seasons of the host plants but also exhibits the bet‐hedging tactic against unpredictable risks due to a dynamic environment.
