Impact of Different Temperatures on Activity of the Pest Monolepta hieroglyphica Motschulsky (Coleoptera: Chrysomelidae).

ABSTRACT: Monolepta hieroglyphica (Motschulsky) (Coleoptera: Chrysomelidae) is widely distributed in China and is polyphorous, being a major pest to cash crops, such as corn, cotton, and millet. Given the increasing severity of the greenhouse effect in recent years, we aimed to investigate the adaptability of M. hieroglyphica adults to varying temperatures. In this study, we assessed the survival, longevity, fecundity, feeding capacity, and antioxidant capacity of leaf beetle adults under laboratory conditions at 25-34 °C. Elevated temperatures (i.e., 31 and 34 °C) had (negative) impacts on M. hieroglyphica adults' survival and reproduction. Similarly, the temperature negatively affected the feeding capacity of M. hieroglyphica adults, with the impact becoming more pronou
