Bottom-up and top-down effects in a tritrophic system: the population fluctuations of Plutella xylostella and its parasitoid, Oomyzus sokolowskii on the cauliflower cultivars in field conditions
Archives of Phytopathology and Plant Protection 47 (6), 681-689
Abstract: The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Yponomeutidae), has worldwide distribution and found wherever cruciferous plants is grown. In this study, fluctuations of parasitism rate of P. xylostella by Oomyzus sokolowskii on different cauliflower cultivars were evaluated in the field during 2011 at research station of the Shahed University (South of Tehran). This investigation was conducted on the eight cauliflower cultivars including Smilla, Snow mystique, White cloud, Buris, Galiblanka, Snow crown, SG and Tokita in a randomised complete block design with five replications. The results showed that density of total larva and pupa of the diamondback moth on Buris and Snow crown cultivars is lower than other cultivars. The highest and the lowest percentage of parasitism by O. sokolowskii was observed on Buris cultivar (7.93 ± 0.91%) and SG cultivar (1.28 ± 0.36%) during the season, respectively.
