The cotton aphid, Aphis gossypii Glover, is known as the most important vectant vector of citrus tristeza virus, cucumber mosaic virus, potato virus Y and potato leafroll virus. This study conducted to investigate the life history of cotton aphid at Suweon, Korea(Lat. 37°16'N, Long. 126°59'E).
The aphids were reared in small cages placed over twig of hibiscus and on the leaves of cucumber. The results obtained were summarized as follows:
1. Overwintering eggs hatched from mid to late April, with a hatching rate averaging seventy-nine percent.
2. The early-born progeny have 22 generations and the late-born progeny have 6 generations on hibiscus and cucumber from April to October.
3. The fundatrigeniae leave the the primary host in late May to early June and migrate to the secondary hosts.
4. From early to mid Oct., the gynoparae migrate from the secondary hosts to the primary host.
5. The average length of life was about 29 days and they produced an average of 70 nymphs each.
6. The maximum number of aphids produced per female was 117 in the spring.
7. The developmental period ranged from 6 to 16 days (average 8 days), the reproductive period from 12.2 to 24.6 days (average 19 days).
8. The average number of nymphs produced by a female per dys was about 3.7, with a maximum number of 17.
