Predominance of parthenogenetic reproduction in Aphis gossypii populations on summer crops and weeds in Greece
Margaritopoulos, J. T.; Tzortzi, M.; Zarpas, K. D.; Tsitsipis, J. A. (2009)The photoperiodic response of 56 parthenogenetic lineages of Aphis gossypii Glover was examined by rearing the aphids for three generations under short day conditions (SD, L 10:13 14) and 17 degrees C. The lineages were ...
