Abstract Cold tolerance of overwintering nymphs of a cockroach, Periplaneta japonica, was examined in terms of the supercooling capacity and lower lethal temperature. The supercooling point of overwintering nymphs fell in a relatively narrow range of temperature from -6 to -9°C and no correlation was observed between the supercooling point and body size. In the temperature range from -5 to -8°C, a significant proportion of cockroaches could tolerate a 12 hr period of tissue freezing. The freeze…

American Cockroach1 Response to Cold Temperatures
Data showed that adult Americancockroaches were not able to survive several days at ≤10°C, suggesting a potential cultural control method for tropical cockroaches.
Evidence for non-colligative function of small cryoprotectants in a freeze-tolerant insect
This study is the first to experimentally demonstrate the importance of non-colligative cryoprotectant function for insect freeze tolerance both in vivo and ex vivo, with implications for choosing new molecules for cryopreservation.
Thermal stress causes DNA damage and mortality in a tropical insect
Experiments in a tropical cockroach, Gromphadorinha coquereliana, show that cold stress does not cause lethal DNA damage, in comparison to freeze stress, and this species can be classified as moderately freezing tolerant.
Broad infectivity of Leidynema appendiculatum (Nematoda: Oxyurida: Thelastomatidae) parasite of the smokybrown cockroach Periplaneta fuliginosa (Blattodea: Blattidae)
It is found that the smokybrown cockroach Periplaneta fuliginosa was primarily infected with only one nematode species Leidynema appendiculatum, and timing of postembryonic development from hatched nematodes larva to mature adult in these hosts was identical with that in P. fulig inosa.
Genome analysis of new Blattabacterium spp., obligatory endosymbionts of Periplaneta fuliginosa and P. japonica
The newly sequenced genomes of BPja and BPfu emphasise the remarkable stability of Blattabacterium genomes supported by their long-term coevolution and obligatory lifestyle in their host insect.
Climatic variability and hemispheric differences in insect cold tolerance: Support from southern Africa
There are regular, unpredictable subzero temperature events in the southern African habitats; such variability appears to be a general feature of many cold habitats in theSouthern hemisphere, which may lead to the observed interhemispheric discrepancies in cold-tolerance strategies.
Insect cold tolerance: How many kinds of frozen?
It is concluded that freezing tolerance is not part of Bale's (1996) continuum, but rather a parallel, alternative strategy of cold tolerance.


Flexible life cycle of a cockroach Periplaneta japonica with nymphal diapause
Results indicate that P. japonica is adapted to northern climates and has a highly flexible life cycle, and a mixed voltinism appears to be adaptive for insects with a long reproductive period.
Freeze tolerance adaptations in the centipede, Lithobius forficatus
Studies were conducted to investigate the adaptations of the wood centipede, Lithobius forficatus, to winter conditions. During winter centipedes were freeze tolerant. However, inoculative freezing

A broader approach than hitherto is advocated, which integrates ecological information with physiological data, in freezing tolerant individuals and in freezing intolerant species.
Fat body cells and calcium phosphate spherules induce ice nucleation in the freeze-tolerant larvae of the gall fly Eurosta solidaginis (Diptera, Tephritidae)
Both calcium phosphate spherules and fat body cells have ice-nucleating activity sufficiently high to explain whole-body crystallization temperatures and represent a new class of heterogeneous ice nucleators that potentially regulate supercooling and promote freeze tolerance in E. solidaginis and possibly in other overwintering insects.
Physiology of cold tolerance in insects.
Future research should be focused on the possible role of other factors in cold hardening such as bound water, dehydration, low-molecular-weight solutes other than polyols, and the biochemical mechanisms forming the basis of the seasonal changes in the cold hardiness of insects.
