AbstractReproductive parameters of Helicoverpa armigera(Hübner) on 10 canola cultivars including ‘Sarigol’, ‘Hayula420’, ‘Opera’, ‘SLM046’, ‘Modena’, ‘RGS003’, ‘Zarfam’, ‘Licord’, ‘Talaye’ and ‘Okapi’ were determined at 25 ± 1 °C, 60 ± 5% RH and the photoperiod of 16: 8 (L: D) h. Furthermore, age-specific H. arimgerafecundity data were fitted to both Analytis and Enkegaard models. Different canola cultivars had a significant effect on reproductive parameters of adults. The highest values of gross fecundity and fertility rates were observed on ‘RGS003’ (2141.2 and 1578.1 eggs, respectively). However, the lowest values of these parameters were recorded on ‘Licord’ (1016.2 and 550.1 eggs, respectively). Among different canola cultivars, net fecundity and fertility rates were found to be the highest on ‘Okapi’ (1254.9 and 916.5 eggs, respectively) and the lowest on ‘Talaye’ (334.4 and 300.5 eggs, respectively). The age-specific data of H. armigerafecundity on ‘SLM046’ and ‘Sarigol’ fitted better (had the highest R2) to Analytis and Enkegaard models, respectively. The results of the cluster analysis based on reproductive parameters of H. armigerarevealed that among the tested cultivars, ‘Licord’ and ‘Talaye’ were the least suitable, while ‘RGS003’ the most suitable host plants for the reproduction of H. armigera. |
