Variation in susceptibility of rapeseed cultivars to the peach potato aphid
Journal of Pest Science 94 (2), 435-449
Abstract: Considering the need for reduction in insecticide use, we studied the potential for antibiosis and the potential for antixenosis in seven highly yielding winter Brassica napus L. cultivars against Myzus persicae (Sulz.). We found evidence for antixenosis, i.e., disruption in probing in non-phloem tissues and a failure in reaching sieve elements in cultivar 'Alister'. We found evidence for antibiosis, i.e., reduced ability of the plant to serve as a host, in cultivar 'Florida'. On 'Alister' and 'Florida', net reproduction and reproductive period duration of M. persicae were the lowest of all studied cultivars. 'Adriana', 'Andromeda', 'Gladius', and 'Kolumb' are intermediately susceptible to M. persicae infestation with medium values of net reproduction and reproduction period duration, and slight disturbances in aphid probing and feeding. 'Artoga' is highly susceptible. On 'Artoga', reproduction period was the longest, daily fecundity and net reproduction of M. persicae were highest, and probing and feeding behaviors were unaltered. Glucoallysin, glucobrassicanapin, gluconapin, gluconapoliferin, progoitrin, glucobrassicin, and 4-OH-glucobrassicin occurred in the leaves of all rapeseed cultivars in similar quantities and proportions and did not affect aphid performance and phloem sap ingestion by M. persicae.
