Cold hardiness of Helicoverpa zea (Lepidoptera: Noctuidae) pupae.
An insect's cold hardiness affects its potential to overwinter and outbreak in different geographic regions. In this study, we characterized the response of Helicoverpa zea (Boddie) pupae to low temperatures by using controlled laboratory measurements of supercooling point (SCP), lower lethal temperature (LT(50)), and lower lethal time (LLTime). The impact of diapause, acclimation, and sex on t...
متن کاملcold hardiness strategy in field collected larvae of scrobipalpa ocellatella (lepidoptera: gelechiidae)
the beet moth, scrobipalpa ocellatella is recognized as a widespread agricultural pest. cold hardiness strategy of the beet moth larvae was investigated through monitoring seasonal changes at supercooling points and lower lethal temperatures. furthermore, the role of microhabitat in winter survival was studied. the mean scps of the last instar larvae was not significantly different from novembe...
متن کاملcold hardiness process of beet armyworm larvae, spodoptera exigua (lepidoptera: noctuidae)
cold hardiness is one of the most common adaptations of insects at low temperatures. to understand the cold hardiness strategy of beet armyworm, spodoptera exigua (hübner), six temperature treatments were tested on the last instar larvae. supercooling points of treatments were not significantly different. two sugars, glucose and trehalose, as well as three polyols, myo-inositol, glycerol and so...
متن کاملCold Hardiness of Woody Plants
stresses caused by their freezing and thawing. A key difference between a hardy plant and a non-hardy plant is believed to be where the ice forms in freezing: inside the living cells or outside of them. If ice forms inside of cells, it is almost always fatal to them, and this is probably the principal cause of frost kill in non-hardy plants. Normally hardy tissue may be killed by moderate tempe...
متن کاملCold Hardiness and Supercooling Capacity in the Overwintering Larvae of the Codling Moth, Cydia pomonella
The codling moth, Cydia pomonella L. (Lepidoptera: Tortricidae), a worldwide apple pest, is classified as a freeze-intolerant organism and one of the most cold-tolerant pests. The objectives of this study were to examine the supercooling point of overwintering and non-diapausing larvae of C. pomonella as an index of its cold hardiness, and to assess larval mortality following 24 h exposure to e...
