Influence of flight and colour morph on susceptibility of Sitobion avenae to infection by Erynia neoaphidis
Biocontrol Science and Technology 12 (6), 753-756
Abstract: The influence of clone and morph on the infection of Sitobion avenae with Erynia neoaphidis was examined in laboratory assays. The LC50-values were low; green alates: 0.8-1.8, green apterae: 2.9, brown alates: 1.5 and brown apterae: 2.6-3.6 conidia mm-2. Within each of the two inoculation occasions, alates of both clones were significantly more susceptible than apterae, while there was no difference between the two clones. The LT50-values at 18°C varied between 6.4 and 7.5 days and there was no significant difference in LT50-values between either the two different coloured clones or between alates and apterae.
