Topical application of ice-nucleating-active bacteria decreases insect cold tolerance.
The majority of overwintering insects avoid lethal freezing by lowering the temperature at which ice spontaneously nucleates within their body fluids. We examined the effect of ice-nucleating-active bacteria on the cold-hardiness of the lady beetle, Hippodamia convergens, a freeze-intolerant species that overwinters by supercooling to ca. -16 degrees C. Topical application of the ice-nucleating...

متن کاملIngestion of Ice-nucleating Active Bacteria Increases the Supercooling Point of the Lady Beetle Hippodamia Convergens
Regulation of the temperature at which insects freeze is a critical factor in their overwintering survival. Although the role of ice-nucleating active bacteria in promoting frost-damage in plants is well known, their interaction with other organisms has not been described. In winter. many freeze-susceptible insects avoid freezing by lowering the temperature at which their body fluids spontaneou...

متن کاملProperties of a novel extracellular cell-free ice nuclei from ice-nucleating Pseudomonas antarctica IN-74.
Some ice-nucleating bacterial strains, including Pantoea ananatis (Erwinia uredovora), Pseudomonas fluorescens, and Pseudomonas syringae isolates, were examined for the ability to shed ice nuclei into the growth medium. A novel ice-nucleating bacterium, Pseudomonas antarctica IN-74, was isolated from Ross Island, Antarctica. Cell-free ice nuclei from P. antarctica IN-74 were different from the ...
