Supercooling point plasticity during cold storage in the freeze-tolerant sugarbeet root maggot Tetanops myopaeformis
The sugarbeet root maggot Tetanops myopaeformis (Röder) overwinters as a freeze-tolerant third-instar larva. Although most larvae are considered to overwinter for only 1 year, some may exhibit prolonged diapause in the field. In the laboratory, they can live for over 5 years using a combination of diapause and post-diapause quiescence. In the present study, the cold survival strategies of these...
متن کاملMulti-year survival of sugarbeet root maggot (Tetanops myopaeformis) larvae in cold storage.
To test the hypothesis that long-term survival of sugarbeet root maggot in storage is facilitated by larvae undergoing prolonged diapause, respiration and gene expression patterns of field-collected diapausing larvae were compared with those of 1-, 2-, and 5-year laboratory-stored larvae. Additional assessments were made on post-storage survival, emergence, and reproductive fitness of stored la...
متن کاملInternal lipids of sugarbeet root maggot (Tetanops myopaeformis) larvae: effects of multi-year cold storage.
Sugarbeet root maggots, Tetanops myopaeformis (Diptera, Ulidiidae), survive more than five years of laboratory cold (6 degrees C) storage as mature third-instar larvae. To quantify energy costs associated with prolonged storage, internal lipids of larvae stored for 1, 2, 3, and 5 years were compared and characterized with those of field-collected diapausing larvae. Internal lipid concentration ...
متن کاملCold-hardening during long-term acclimation in a freeze-tolerant woolly bear caterpillar, Pyrrharctia isabella.
The banded woolly bear caterpillar, Pyrrharctia isabella (Lepidoptera: Erebidae), overwinters in leaf litter and survives freezing under natural conditions. Following 18 weeks of cold acclimation at 5°C, all caterpillars could survive 1 week of continuous freezing at -20°C or seven cycles of freezing-thawing at -20°C, but none survived freezing at -80°C. Field-collected caterpillars had a tempe...
متن کاملSupercooling and Freezing Tolerant Animals
Subzero temperatures may adversely affect animals by their direct lethal effects and by the damage caused by ice formation (Ramløv, 2000). Animals deal with the latter by three basic strategies. Freeze avoiding animals prevent ice formation in their bodies and supercool, keeping their body fluids liquid at temperatures below their melting point, but die if freezing occurs. In contrast, freezing...
