The Effect of Some Biological Parameters of Brevicoryne brassicae (L.) (Hemiptera: Aphididae) on Different Cauliflower Cultivars

Abstract

In this article, some biological parameters of Brevicoryne brassicae were studied on four different cauliflower cultivars (Casper RZ, Barcelona F1, Karbeyaz F1 and Mor karnabahar). This study was conducted under controlled conditions: 25±1 0 C, 65±5% relative humidity (RH), and 16:8 (L:D) h photoperiods. The maximum and minimum developmental times were observed on Karbeyaz F1 and Barcelona F1 cultivars, respectively. When we examine the total development period, the shortest Barcelona F1 cultivar (6.73 days) and the longest total nymphal growth period were determined on Karbeyaz F1 (7.07 days). When the biological parameters of B. brassicae were examined, it was determined that the varieties with the lowest rm values were on Barcelona F1 cultivar. When the Ro values are compared, it is seen that the lowest value is obtained in Barcelona F1 variety. When the To values were examined, it was determined that the lowest value was obtained on Karbeyaz F1 variety, followed by Barcelona F1, Casper RZ and Mor karnabahar varieties.
