| 本研究在6个恒温(18?21?24?27?30?33℃)条件下, 观察并记录了白茨粗角萤叶甲Diorhabda rybakowi卵?幼虫与蛹的发育历期和存活率, 以及成虫的寿命和繁殖力?结果表明, 卵和幼虫的发育历期随温度升高而缩短, 发育速率随之加快?白茨粗角萤叶甲的卵?幼虫期?蛹?成虫产卵前期和世代的发育起点温度分别为(10.4±0.8)?(12.2±0.7)?(8.7±0.9)?(16.4±0.8)℃和(8.6±0.9)℃, 有效积温分别为(97.9±4.8)?(158.2±7.9)?(212.1±11.5)?(158.6±13.6)日·度和(838.0±43.9)日·度?在低温18℃和高温33℃条件下, 白茨粗角萤叶甲幼虫的存活率均降低, 成虫的羽化率在33℃高温下显著降低, 而卵的存活率高于幼虫期的存活率?白茨粗角萤叶甲生长发育和繁殖的最适温区为21℃ |
| 英文摘要: |
| The developmental duration and survival rate of egg, larva and pupa and adult longevity and fecundity of Diorhabda rybakowi were investigated under six constant temperatures (18, 21, 24, 27, 30, 33℃) in this study. The results showed that the developmental durations of egg and larva declined and the growth rate accelerated along with the increase of temperature. The threshold temperatures for development of egg, larva, pupa, pre-oviposition of adult and generation of D. rybakowi were (10.4±0.8), (12.2±0.7), (8.7±0.9), (16.4±0.8)℃ and (8.6±0.9)℃, respectively, and the effective accumulated temperatures were (97.9±4.8), (158.2±7.9), (212.1±11.5), (158.6±13.6) and (838.0±43.9) degree-days, respectively. The larval survival rate decreased at 18℃ and 33℃, and the adult emergence rate decreased significantly at 33℃, while the egg survival rate was higher than the larval survival rate. The optimum temperature(T)range for the growth, development and reproduction of D. rybakowi was 21℃ |
