摘要： 【目的】本研究旨在测定不同存储温度和时间下，七星瓢虫Coccinella septempunctata、异色瓢虫Harmonia axyridis和龟纹瓢虫 Propylaea japonica卵孵化率和孵化时间，探究3种商品化瓢虫卵的最佳贮存温度和时间。【方法】将七星瓢虫、异色瓢虫和龟纹瓢虫室内饲养新产的卵置于6, 8和10 ℃下，冷藏3, 5, 7, 9, 11, 13和15 d后测定卵的孵化率；将七星瓢虫、异色瓢虫和龟纹瓢虫新产卵分别置于15, 20和25 ℃下，测定卵的孵化时间。【结果】七星瓢虫卵在6, 8和10 ℃下冷藏5 d内孵化率均高于80%， 6, 8和10 ℃下冷藏超过5 d时孵化率差异显著， 10 ℃下卵孵化率最高， 10 ℃下11 d时孵化率可达到56.1%。异色瓢虫卵对低温更敏感，在10 ℃下冷藏7 d时孵化率为85.3%，而6 ℃下冷藏7 d孵化率仅有6.1%;在10 ℃下冷藏11 d内孵化率不低于50%。龟纹瓢虫卵对低温最敏感，在10 ℃冷藏7 d时孵化率降为34.3%，在6和8 ℃冷藏3 d时孵化率降为0。这3种瓢虫卵的孵化时间随温度的降低而延长，15 ℃下为7~8 d，20 ℃下为4~5 d，25 ℃下为2~3 d。【结论】七星瓢虫和异色瓢虫卵的最佳贮存温度均为10 ℃， 10 ℃下冷藏7 d内其孵化率均高于85%。龟纹瓢虫卵不适合冷藏。可通过降低孵化温度至15 ℃延长瓢虫卵的货架期。

Abstract: 【Aim】This study aims to determine the hatching rates and hatching duration of Coccinella septempunctata, Harmonia axyridis and Propylaea japonica eggs stored under different temperatures for different duration, so as to explore the optimal storage temperature and duration of the three commoditized ladybird eggs.【Methods】After the newly laid eggs of C. septempunctata, H. axyridis and P. japonica were maintained under 6, 8 and 10 ℃ for 3, 5, 7, 9, 11, 13 and 15 d, the hatching rates were determined. The newly laid eggs of C. septempunctata, H. axyridis and P. japonica were placed at 15, 20 and 25 ℃, and the egg hatching duration was tested. 【Results】The hatching rates of C. septempunctata eggs stored under 6, 8 and 10 ℃ within 5 d were higher than 80%. The hatching rates of C. septempunctata eggs stored under 6, 8 and 10 ℃ for more than 5 d showed significant difference, and their hatching rate under 10 ℃ was the highest. The hatching rate of C. septempunctata eggs stored under 10 ℃ for 11 d was 56.1%. H.axyridis eggs were more sensitive to low temperatures. When H.axyridis eggs were stored under 10 ℃ for 7 d, the hatching rate was 85.3%, while that of H. axyridis eggs stored under 6 ℃ for 7 d was only 6.1%. When H. axyridis eggs were stored under 10 ℃ within 11 d, the hatching rate was not less than 50%. P. japonica eggs were the most sensitive to low temperatures. The hatching rate of P. japonica eggs was decreased to 34.3% when stored under 10 ℃ for 7 d and decreased to 0 when stored under 6 and 8 ℃ for 3 d. The egg hatching duration of the three ladybird species increased with the decrease of incubation temperature. The egg hatching duration of the three ladybird species was 7-8, 4-5 and 2-3 d, respectively, under 15, 20 and 25 ℃. 【Conclusion】The optimial storage temperature is 10 ℃ for C. septempunctata and H. axyridis eggs, and their hatching rates are higher than 85% when stored under 10 ℃ within 7 d. Cold storage is not applicable for P. japonica eggs. The shelf life of ladybird eggs can be extended by reducing the incubation temperature to 15 ℃.
