Results revealed that P. solenopsis successfully and significantly (P<0.05) completed its life cycle along with highest body weight gain on China rose followed by potato. Moreover, P. solenopsis had the best survival (34.2 ± 3.8 days) and reproduction (7.8 ± 0.4 nymphs/adult female) when separated and kept without food from their respective host plants. China rose therefore seems to have the p...

...cues, as temperature and photoperiod, play important roles in animals’ physiological adjustments. In order to determine the contributions of temperature and photoperiod to seasonal changes in body mass and thermogenesis in Apodemus chevrieri, we examined seasonal-acclimatized and lab-acclimated animals on several physiological, hormonal, and biochemical markers indicative of thermogenic capacity. The result...
