Post-release establishment and supercooling point assessment of Laricobius osakensis, a predator of the hemlock woolly adelgid
… tree health. Understanding more about the supercooling point of L. osakensis gave insight to its ability to survive subfreezing temperatures as occurred in 2014. Comparison of the supercooling point between the northern and southern populations of L. osakensis, and to the other released HWA …

Cold Tolerance, Diapause and Winter Survival of the Brown Marmorated Stink Bug (<i>Halyomorpha halys</i>)
… by determining its cold tolerance strategy and supercooling ability via the supercooling point (SCP). Metabolic suppression (as measured by flow-through respirometry) indicated that diapause was induced by a critical photoperiod of 11h:13h (L:D), indicating a process potentially influenced by …

Overwintering biology of the brown marmorated stink bug, Halyomorpha halys (Hemiptera: Pentatomidae)
… tolerance. Overwintering H. halys depress their supercooling point to -15.4 °C and LT50 to -17.5 °C after acute (1 h) exposure, however they do not encounter these temperatures while overwintering indoors. Moreover, overwintering H. halys maintain their water balance through a reduction of water …

Field biology and mortality factors affecting Cassida rubiginosa Müller (Coleoptera: Chrysomelidae), a biological control agent of Canada thistle (Cirsium arvense (L.) Scop.)
… compatible with water saturated soil. The mean supercooling point of C. rubiginosa in summer was -5.2 ± 1.5°C and was significantly different (P<0.05) from mean supercooling points of -9.3 ± 2.1°C in fall and -8.8 ± 2.3°C in winter. Females studied individually produced an average of 61.1 ± 29.9 …

Cold Tolerance, Temperature Mediated Discontinuous Gas Exchange, and Emergence of the Blue Orchard Mason Bee (<i>Osmia lignaria</i>)
… between low temperatures, emergence and supercooling point of <em>Osmia lignaria </em>were the subject of this study. One hundred sixty-eight bees were subjected to 5 pre-wintering temperature treatments (two constant temperature controls - 22<sup>o</sup>C, 14<sup>o</sup>C, one of which …

Biology and Management of Brown marmorated Stink Bug, Halyomorpha halys (Stål), in Agricultural and Urban Environments
… sex, and location of acclimation. The mean supercooling point (± SEM) in the winter in Minnesota was -17.06°C ± 0.13° and in Virginia was -13.90°C ± 0.09°. Laboratory experiments conducted in Blacksburg, VA were able to determine baseline lethal high temperatures over time against H. halys …
