Popis: | Temperature is one of the most important abiotic factors that influences the development and growth of insects. We investigated the effect of temperature on the development of the weevil Eucryptorrhynchus brandti (Harold). The developmental zeros and effective accumulated temperatures for different developmental stages of E. brandti were estimated under variable temperatures in the laboratory. We observed that the developmental zeros of eggs, larvae, and pupae were 15.27 °C, 20.86 °C, and 14.04 °C, respectively, and the effective accumulated temperatures were 81.46 °C·d, 293.76 °C·d, and 127.76 °C·d, respectively. The rate of development increased as the temperature increased within a particular temperature range, and temperatures from 30 °C to 31 °C were particularly suitable for E. brandti rearing. Based on these results, we may be able to predict the occurrence of E. brandti, providing a reference for physical control measures targeting adults to effectively reduce oviposition and minimize population expansion. |
