摘要
在室内22℃条件下,利用年龄-龄期两性生命表理论研究了济麦22上麦长管蚜种群生命表,并比较了有翅型和无翅型麦长管蚜的发育历期和繁殖力。结果发现,济麦22上麦长管蚜的寿命为23.0±1.0d,繁殖力为24.6±1.1头/雌。种群的内禀增长率(r)、周限增长率(λ)、净生殖率(R0)和平均世代周期(T)分别为0.22±0.01 d-1、1.25±0.01 d-1、20.28±1.38头、13.48±0.19 d。济麦22上有翅型麦长管蚜若蚜历期、产蚜前期显著长于无翅型,但成蚜期、产蚜历期和繁殖力却显著低于无翅型。
The population life table of Sitobion avenae was analyzed using the age -stage two -sex life table theory, and the developmental period and fecundity of winged and wingless adult were studied on the wheat variety Jimai22 at 22℃ in laboratory. The results showed that the longevity of aphid was 23.0 ± 1.0 d, the fecundity was 24.6 ±1.1 nymphs per female. The intrinsic increase rate （ r）, finite increase rate （ k）, net reproductive rate （R0） and mean generation time （T） were 0.22 ±0.01 d-1, 1.25 ±0.01 d^-1, 20.28 ±1.38 nymphs and 13.48 ±0.19 d, respectively. The survival rate of nymph and preoviposition period of winged morph were significantly longer than those of wingless morph, however, the adult longevity, oviposition period and fecundity of winged morph were significantly shorter than wingless morph on the wheat variety of Jimai 22.
