| 为搞清楚温度与桧柏臀纹粉蚧Planococcus vovae生长发育、繁殖的关系，本研究在6个恒温条件下（17℃、20℃、23℃、26℃、29℃和32℃），测定了各虫态的存活率、发育历期、发育起点温度、有效积温、繁殖力和发育速率等相关参数，并构建了实验种群生命表。结果显示：1）温度对桧柏臀纹粉蚧各虫态的发育历期有重要影响，在20~32℃恒温条件下，桧柏臀纹粉蚧各虫态的发育历期随温度的升高先缩短后延长；雌若虫发育历期在26℃时仅为27.00 d；而雄若虫的发育历期在29℃下最短，为23.17 d。雌、雄若虫期在20℃时发育历期最长，分别为92.06 d和86.80 d。2）桧柏臀纹粉蚧各虫态发育速率与温度之间呈二次回归关系，但雄虫蛹期除外。3）在26℃时雌、雄若虫的存活率显著高于其他温度，分别为64.58%和64.27%。4）雌成虫产卵前期和成虫寿命随着温度的升高逐渐缩短；雌成虫产卵量从26℃下的每雌193.25粒缩减到17℃下的每雌84.20粒。5）世代发育起点温度分别为雌19.04℃、雄15.02℃，有效积温分别为461.29日·度和353.42日·度。6）26℃和20℃下的种群趋势指数分别为62.3和16.1；17℃时，2龄若虫生长停滞，持续期达80 d以上；32℃时2龄、3龄若虫发育历期延长。桧柏臀纹粉蚧最适宜在23~29℃生长发育和繁殖。 |

| In order to investigate the influence of temperature on the growth, development and reproduction of Planococcus vovae, the survival rate, developmental period, developmental threshold temperature, effective accumulated temperature, fecundity and developmental rate of P. vovae were measured at 17℃, 20℃, 23℃, 26℃, 29℃ and 32℃ under six constant temperature conditions, and the laboratory population life table at different temperatures was constructed. Results showed: 1) The temperature significantly influenced the developmental period of P. vovae, the developmental period of different stages of P. vovae decreased and then increased as temperature increasing from 20℃ to 32℃; the shortest period was 27.00 d for the female at 26℃ and 23.17 d for the male at 29℃; the longest developmental duration of female and male nymph were 92.06 d and 86.80 d, respectively, at 20℃. 2) There was a quadratic regression between developmental rates and temperature for each insect state of P. vovae, except for the pupal stage of males. 3) The highest survival rate of the female and male were 64.58% and 64.27%, respectively at 26℃. 4) Both pre-oviposition and adult longevity of female adults declined progressively with increasing temperatures. The egg production was the highest at 26℃ with 193.25 eggs per female and lowest at 17℃ with 84.20 eggs per female. 5) The developmental threshold temperatures of the female and male generations were 19.04℃ and 15.02℃, and the effective cumulative temperatures were 461.29 day-degrees and 353.42 day-degrees. 6) The population trend index was 62.3 and 16.1 at 26℃ and 20℃, respectively; the second instar of P. vovae showed growth stagnation at 17℃, which lasted for more than 80 d; the developmental period of the second and third instars of P. vovae was all prolonged at 32℃. The most suitable temperature range is 23~29℃ for the growth, development and reproduction of P. vovae. |
