Abstract
The reproduction of apterous and alate morphs of the aphids Sitobion avenae and Metopolophium dirhodum is compared on the basis of fecundity in 5- and 10-day periods of adult life. Apterae of both species are consistently more fecund than alatae of comparable weight, producing about three more nymphs on average in any 5-day period. The reproductive differences are related to the number and quality of embryos at eclosion and to ovulation rates, both of which in turn appear to be linked to wing-muscle maintenance. These relationships between weight, embryos and reproduction may be used to predict a newly moulted adult aphid's fecundity, a method which may facilitate the assessment of resistance to aphids in new cereal varieties, by obviating lengthy recording of reproduction. The strategies by which alatae of these and other aphid species minimize the difference between their fecundity and that of apterae are discussed.
期刊介绍：
Annals of Applied Biology is an international journal sponsored by the Association of Applied Biologists. The journal publishes original research papers on all aspects of applied research on crop production, crop protection and the cropping ecosystem. The journal is published both online and in six printed issues per year.
Annals papers must contribute substantially to the advancement of knowledge and may, among others, encompass the scientific disciplines of:
Agronomy
Agrometeorology
Agrienvironmental sciences
Applied genomics
Applied metabolomics
Applied proteomics
Biodiversity
Biological control
Climate change
Crop ecology
Entomology
Genetic manipulation
Molecular biology
Mycology
Nematology
Pests
Plant pathology
Plant breeding & genetics
Plant physiology
Post harvest biology
Soil science
Statistics
Virology
Weed biology
Annals also welcomes reviews of interest in these subject areas. Reviews should be critical surveys of the field and offer new insights. All papers are subject to peer review. Papers must usually contribute substantially to the advancement of knowledge in applied biology but short papers discussing techniques or substantiated results, and reviews of current knowledge of interest to applied biologists will be considered for publication. Papers or reviews must not be offered to any other journal for prior or simultaneous publication and normally average seven printed pages.
