在我们努力了解蚜虫生物学的过程中，我们试图在实验室中使用化学定义的人工饲料来维持它们。研究了来自Eriosomatinae和Hormaphidinae亚科的16种昆虫在人工饲料中的生存能力，其中大部分是产酶物种。有些物种既不进食也不生长，而其他物种接受饮食，在一定程度上生长，并设法产生少量短命的后代。虽然他们表现不佳的饮食在一般情况下，蚜虫的性能与生命周期的阶段和发育阶段，蚜虫的虫瘿一代往往接受的饮食和生存，而蚜虫的非虫瘿一代没有，而且，老昆虫往往表现得更好的饮食比年轻的蚜虫。值得注意的是，只有一个物种，即styraci，一种产生2龄不育士兵的成瘿蚜虫，在饮食上表现出良好的性能。从虫瘿收集的昆虫（GO代）在饮食中存活，生长良好，并产生许多后代。连续三代（G1、G2和G3）在饮食上产生。发育期，成人的身体大小，和ACE的第一次繁殖几乎是恒定的，通过GO，G1和G2，而繁殖力，成人寿命和每日的后代产量下降，代进行。这些结果与以前的研究相当，在以前的研究中，害虫蚜虫已经保持了几代类似的人工饲料。因此，人工饲料饲养系统将为研究产蚜真社会性蚜虫的生物学特性提供有用的工具。苏合香(C)2002爱思唯尔科技有限公司。保留所有权利。
In our efforts to understand the biology of soldier-producing aphids, we attempted to maintain them in the laboratory using a chemically defined artificial diet. The ability of 16 species from the subfamilies Eriosomatinae and Hormaphidinae, most of which are soldier-producing species, to survive on the artificial diet was examined. Some species neither fed nor grew on the diet, whereas other species accepted the diet, grew to some extent, and managed to produce a small number of short-lived offspring. Although they performed poorly on the diet in general, aphid performance was correlated with the stage in the life cycle and the developmental stadium in that aphids of the gall generation tended to accept the diet and survive on it, whereas aphids of the non-gall generation did not, Also, old insects tended to perform better on the diet than young nymphs. Notably, only one species, Tuberaphis styraci, a gall-forming aphid that produces 2nd instar sterile soldier, showed good performance on the diet. Insects collected from galls (generation GO) survived on the diet, grew well, and produced many progeny. Three successive generations (G1, G2 and G3) were produced on the diet. Developmental period, adult body size, and ace of first reproduction were almost constant through GO, G1 and G2 whereas fecundity, adult longevity and daily offspring production declined as the generations proceeded. These results are comparable to previous studies in which pest aphids have been maintained on similar artificial diets for several generations. Therefore, it is suggested that the artificial-diet rearing system will provide a useful tool to investigate various biological aspects of the soldier-producing eusocial aphid, T. styraci.
