Pattern of growth and fat content of somatic and gonadal tissues of virginoparae of the vetch aphid, Megoura viciae
1990
Brough, C.N. | Dixon, A.F.G. | Kindlmann, P.
Throughout the development of virginoparous apterae of the vetch aphid, Megoura viciae, the percentage water content remained constant. Over the period from birth to the onset of reproduction the somatic tissues grew logistically and the gonads exponentially. During development the percentage of the weight of an aphid that consisted of gonads increased. The sigmoidal pattern of growth in weight of an aphid reflects the combined growth patterns of the somatic and gonadal components. Large adults had proportionally bigger gonads than small adults. The fat (lipid) content of both the soma and gonads increased during development; in the soma up to the adult moult, and the gonads up to the onset of reproduction.
