摘要
为明确新疆野苹果Malus sieversii吉尔吉斯与栽培苹果Malus domestica金冠对苹果全爪螨Panonychus ulmi生长发育和繁殖的影响,在室温23±1℃,相对湿度75%±5%,光周期16L∶8D条件下,组建了苹果全爪螨在吉尔吉斯和金冠上的实验种群两性生命表。结果显示:吉尔吉斯和金冠对苹果全爪螨雌螨寿命、产卵期及总产卵量等有明显影响、而对总发育历期、总产卵前期、未成熟螨存活率等影响不显著。苹果全爪螨总发育历期在吉尔吉斯(雌12.60d,雄11.40d)和金冠(雌12.54d,雄11.67d)上无显著差异,雌成螨寿命在金冠(13.46d)上显著长于在吉尔吉斯(10.88d)上(P<0.05)。产卵期在金冠和吉尔吉斯上分别为10.55d和8.30d,达到显著差异水平(P<0.05)。总产卵量在金冠上为34.12粒/雌,显著高于在吉尔吉斯上(22.48粒/雌)(P<0.05)。苹果全爪螨在吉尔吉斯上内禀增长率(r)、净增殖率(R0)、世代平均周期(T)、周限增长率(λ)分别为0.1354,11.96,18.33和1.1450,而在金冠上分别为0.1489,17.39,19.18和1.1606。由种群动态参数可知,苹果全爪螨在金冠上种群数量增长快于在吉尔吉斯上。研究结果有助于深入了解该螨在新疆野苹果与栽培苹果上种群动态,并为苹果抗螨性育种及害螨综合治理提供理论依据。
In order to understand the influence of Malus sieversii subsp, kirghisorum and M. domestica Golden Delicious on the development and reproduction of the European red mite, Panonychus ulmi （Koch）, age-stage two-sex life tables of the experimental population of P. ulmi on the two varieties under the conditions of 23 ± 1℃, 75%±5% relative humidity and a photoperiod of 16L： 8D in the laboratory were constructed. The results showed that there were significant differences in female adult longevity, oviposition period and fecundity between P. ulmi mites reared on M. sieversii subsp. kirghisorum and on M. domestica Golden Delicious （P 〈 0.05 ）. However, no significant difference was found in total developmental duration, total pre-oviposition period and survival rate of immatures between P. ulmi mites on M. sieversii subsp, kirghisorum and on M. domestica Golden Delicious. The total developmental duration of P. ulmi on M. sieversii subsp, kirghisorum and M. domestica Golden Delicious were 12.60 d and 12.54 d for females, and 11. 40 d and 11.67 d for males, respectively. The longevity of female P. ulmi mites reared on M. domestica Golden Delicious （ 13.46 d） was longer than those on M. sieversii subsp, kirghisorum （ 10.88 d）. The oviposition periods of P. ulmi on M. domestica Golden Delicious and M. sieversii subsp, kirghisorum were 10.55 d and 8.3 d, respectively. The number of eggs laid per female was significantly higher on M. domestica Golden Delicious （34.12 eggs/female） than on M. sieversii subsp, kirghisorum （22.48 eggs/female） （ P 〈 0.05 ）. The intrinsic rate of increase （r）, the net reproductive rate （ R0） , the mean generation time （T） and the finite rate of increase （ λ ） of P. ulmi mites reared on M. sieversii subsp, kirghisorum were 0. 1354, 11. 96, 18. 33 and 1. 1450, respectively, while those reared on M. domestica Golden Delicious were 0. 1489, 17.39, 19. 18 and 1. 1606, respectively. The results of population dynamic parameters suggest that the population growth of P. ulmi mites reared on M. domestica Golden Delicious is quicker than those reared on M. sieversii subsp, kirghisorum. The results may contribute to further understanding of the population dynamics of P. ulmi occurring on M. sieversii and M. domestica, and provide a theoretical basis to breed mite-resistant apple varieties and to promote comprehensive management for P. ulmi.
