中文摘要: |
为了研究温度对茶树柿广翅蜡蝉越冬卵发育的影响, 设置13、16、19、22、25℃和28℃不同恒温和室外自然变温(日均温度波动范围8.87~26.40℃, 日均温度平均值16.89℃)处理茶树柿广翅蜡蝉越冬卵, 监测其发育历期和孵化情况。结果表明, 在上述6个不同恒温条件下, 柿广翅蜡蝉越冬卵的发育历期分别为62.28、28.58、13.51、10.11、10.33 d和7.07 d, 随着温度的升高, 越冬卵发育历期逐渐缩短, 温度与柿广翅蜡蝉越冬卵的发育速率关系满足方程:y=-0.086+0.008x, 得出越冬卵发育起点温度为10.80℃, 有效积温为125 d·℃。在自然变温条件下, 发现越冬卵从4月10日开始孵化, 到5月5日累计孵化率达到73.37%, 揭示了茶树柿广翅蜡蝉越冬卵在这段时间范围内陆续孵化出1龄若虫。本研究对信阳茶区茶树柿广翅蜡蝉若虫发生期的预测预报及其防控策略的制定具有重要的指导意义。 |

In order to clarify the effects of temperature on the development of overwintering eggs of Ricania sublimbata Jacobi, the developmental duration and egg hatching rate of this pest were investigated at constant temperatures of 13, 16, 19, 22, 25℃ and 28℃ in the laboratory and under natural temperature outdoors (the daily mean temperature ranged from 8.87℃ to 26.40℃, with a daily average temperature of 16.89℃). The results showed that the developmental durations of the overwintering eggs at constant temperatures were 62.28, 28.58, 13.51, 10.11, 10.33 and 7.07 days, respectively, and the higher the temperature, the shorter the developmental duration of the overwintering eggs. The relationship between temperatures and development rates of R. sublimbata overwintering eggs satisfied the equation: y=-0.086+0.008x. The developmental threshold temperature was 10.80℃ and the effective accumulated temperature was 125 degree-days. The overwintering eggs of R. sublimbata begun to hatch on April 10 under natural temperature conditions outdoors, and the cumulative hatching rate reached 73.37% on May 5. The results revealed that the first-generation nymphs hatched from overwintering eggs of R. sublimbata during this period in Xinyang tea area. This study laid a theoretical basis for the prediction of occurrence period and the control strategy of this pest in Xinyang tea-producing area. |
