Apfelwickler-Granulovirus: Erste Hinweise auf Unterschiede in der Empfindlichkeit lokaler Apfelwickler-Populationen
[Codling moth granulovirus: First indication of variations in the susceptibility of local codling moth populations]
Nachrichtenblatt des Deutschen Pflanzenschutzdienstes 57 (2), 29-34
Abstract: This study is part of a BMVEL project for the prevention of codling moth damage by long term population control on large areas. Local codling moth populations were collected in three different orchards, two of them having been treated with CpGV over many years (Bodensee II and Südbaden) and one since two years (Bodensee I). The susceptibility of the offsprings of the overwintering larvae against the granulovirus of codling moth (CpGV "Mexican strain") was investigated in bioassays on artificial diet and compared with a laboratory strain of the codling moth. The results indicated significant differences in sensitivity to the virus between the three local codling moth populations, Südbaden and Bodensee II being much less susceptible than Bodensee I and the laboratory strain.
