Potato aphid catches and virus infestation in seed potato production. Results in Mecklenburg-Vorpommern from 1992 to 2002.

摘要

Results of aphid catches with yellow traps during 1992-2002 are presented. Data were recorded in the German northeastern federal state of Mecklenburg-Vorpommern. The following virus vectors and aphid species were recorded: Myzus persicae, Aphis nasturtii, Aphis frangulae, Aulacorthum solani and Macrosiphum euphorbiae. Results show unimportant levels of catches from mid-May to June. A comparison between the catching methods with yellow traps and a sucking trap shows constant higher catches with the later, and it is concluded that the yellow traps are sufficient for field use. It is also concluded that catches in Mecklenburg-Vorpommern are below other German potato seed producing areas like Niedersachsen and Bayern. The colder maritime climate seams to successfully limiting the spread of aphids.
