Zusammenfassung: | Population fluctuations of Aphis craccivora, Aphis gossypii and their natural enemies in early season in cotton fields in Cukurova region, were studied in this work. A. craccivora, A. gossypii and very low population of Mysuz persicae were observed in early season in cotton fields. The infestation of A. craccivora was seen in early occurrence of A. craccivora changed between 9 and 33 days in the fields where experiments were conducted. At the beginning of growing season population of A. gossypi was lower than A. craccivora. After that when population of A. craccivora disappeared, A. gossypii population was started to increase |
