| 中文摘要: |
| 温度是昆虫生长发育的重要影响因子之一。本研究以室内25℃、L∥D=16 h∥8 h、80%RH条件下终年饲养的褐飞虱1日龄初孵若虫、10日龄高龄(4~5龄)若虫、羽化1日龄短翅型和长翅型雌雄成虫为研究对象, 采用持续升温和恒温相结合的方法, 研究比较了褐飞虱各虫态耐热性。研究结果表明: 长翅雄成虫对温度变化的适应能力较弱, 耐热性差; 短翅型雌成虫耐热性强; 成虫的耐热性强于若虫。开展对昆虫的耐热性研究可为害虫的预测预报和防治提供重要的理论依据。 |
| 英文摘要: |
| Temperature is one of the most important factors affecting the growth and development of insects. In this study, the thermal tolerance of the brown planthoppers (BPHs) was compared under continuous heating and constant temperature, by using several forms of BPHs, including male or female brachypterous and macropterous adults of 1 day after eclosion, 1 and 10 d-old nymphs, which were all reared for a long time under the conditions of 25℃, L∥D=16 h∥8 h and 80% relative humidity. The results showed that BPH adults had stronger thermal tolerance than nymphs, and female brachypterous adults had stronger adaptability to temperature change than male macropterous adults. This study on insect thermal tolerance may be helpful to prediction and control of pests. |
