Abstract

The foxglove aphid, Aulacorthum solani (Kaltenbach), is a polyphagous economic pest. In this study, A. solani were fed on detached leaves of dockleaf knotweed, Persicaria lapathifolia (L.) Delarbre. Survival, development, and reproduction were studied at constant temperatures of 17, 20, 23, 26, 29, and 32 °C. These data were compared with those of controls fed on Glycines max (L.) Merrill. At 17, 20, 23, and 26 °C, the survival rate of A. solani adults fed on P. lapathifolia were lower than those fed on G. max; the adult longevity, aphid total longevity, and reproduction period were shorter. At 20, 23, and 26 °C, the adult fecundity, intrinsic rate of increase, finite rate of increase, and net reproductive rate of A. solani fed on P. lapathifolia were smaller than those fed on G. max. At 29 °C, the survival rate of A. solani adults fed on P. lapathifolia were higher than those fed on G. max; the adult longevity and aphid total longevity were longer. These results are consistent with our finding that A. solani feed on P. lapathifolia, which is important for studying the host adaptability of A. solani.

以青叶柿为食的 Aulacorthum solani(半翅目:蚜科)的生存、发育和繁殖。
凤仙花蚜 Aulacorthum solani (Kaltenbach) 是一种多食性经济害虫。在这项研究中,A. solani 被取食于坞叶结缕草Persicaria lapathifolia (L.) Delarbre的分离叶片上。在 17、20、23、26、29 和 32 °C 的恒温条件下研究了其存活、发育和繁殖情况。这些数据与以 Glycines max (L.) Merrill 为饲料的对照组的数据进行了比较。在 17、20、23 和 26 °C条件下,喂食 P. lapathifolia 的蚜虫成虫存活率低于喂食 G. max 的成虫;成虫寿命、蚜虫总寿命和繁殖期均较短。在 20、23 和 26 °C条件下,喂食 P. lapathifolia 的 A. solani 的成虫繁殖率、内在增长率、有限增长率和净生殖率均小于喂食 G. max 的 A. solani。在 29 °C 条件下,以 P. lapathifolia 为饲料的 A. solani 成虫存活率高于以 G. max 为饲料的成虫存活率;成虫寿命和蚜虫总寿命更长。这些结果与 A. solani 以 P. lapathifolia 为食的发现一致,这对研究 A. solani 的寄主适应性非常重要。
