“…Adult H. axyridis mainly accumulated myo-inositol during the winter. A similar phenomenon is also known in other beetles belonging to the Chrysomelidae and Coccinellidae (Hoshikawa, 1981(Hoshikawa, , 1987Hoshikawa et al, 1988;Košťál et al, 1996;Watanabe & Tanaka, 1998). In this study, the seasonal change of myo inositol content correlated significantly with the pattern for change of SCP, lower lethal temperature and chilling tolerance at -5°C.…”

Abstract. I investigated the seasonal changes of cold tolerance and polyol content in adults of Harmonia axyridis to elucidate their overwintering strategy. Adults decreased their supercooling point and lower lethal temperature only during the winter. Although the seasonal trends for both values were almost consistent, there seemed to be considerable mortality, without being frozen, at -20°C in mid-winter. The pattern for seasonal change in tolerance at moderately low temperatures differed among the temperatures exposed: the survival time at -5°C peaked in winter, but the time at 5 or 0°C peaked in autumn. Because both autumn and winter adults were completely paralyzed only at -5°C and survived much longer at 0°C than at 5°C, the survival time at -5°C indicates the degree of chilling tolerance, whereas the time at 5 or 0°C seems to show starvation tolerance. This beetle accumulated a relatively large amount of m yo-inositol during winter. Myo-inositol content synchronized seasonally with supercooling capacity, the lower lethal temperature and the chilling tolerance, suggesting that m yo-inositol may play some role in the control of cold tolerance in this beetle.

“…The adjustment to external temperatures by behaviour (migration) may be facilitated in shallow litter. For example, beetle species may show different abilities to vertical migration to deeper soil in response to external temperature (Hoshikawa et al 1988).…”

“…Many scarab larvae overwinter as third instars at depths of 5Ð25 cm to avoid freezing (McColloch et al 1928, Hoshikawa et al 1988. Grubs may also burrow downward in response to heat or drought (Villani and Nyrop 1991).…”
