How can you use “aphids” in a sentence? Here are some example sentences to help you improve your vocabulary:
Transferring aphids from 0-4°C to 16°C on day 49 resulted in almost immediate katatrepsis followed by a rapid completion of development (figure 7).
According to Behrandt, diapause occurs at the end of anatrepsis (germband immersion) in Aphis fabae . This has been corroborated by the observation that in Sitobioum graminum the majority of embryos also pass winter at the end of anatrepsis [ 13 ] , and the same may be true of Aphis pomi in Virginia USA [ 14 ] . Other aphids, however, including German clones of Aphis pomi, appear to develop constantly throughout the winter, with no definite resting stage [ 15 ] . A resting stage is a widely reported characteristic of diapause [ 1 2 16 17 18 ] and so the extent to which diapause occurs generally in aphids is therefore in some doubt.
In aphids, and most other insects, however, there is a strong relationship between temperature and developmental rate [ 19 ] . In order, therefore, to determine whether any resting stage we observed at 0-4°C was truly diapause and not a consequence of low rearing temperatures, we also tracked the development of embryos maintained under warmer conditions (10°C and 16°C).
Among fully sequenced published genomes, the only instance of a highly reduced genome that shows a close relationship to large genomes is Buchnera aphidicola, the obligate endosymbiont of aphids (Insecta).
We produced sexually reproducing male and female aphids by exposing asexual females from a single clone (LSR1, collected near Ithaca, NY) to 'autumnal' conditions (short-day illumination, 13L:11D, 16°C) for five weeks.
