| The reorganisation from conventional to organic farming practice on a farm located in Northern Germany was accompanied in a long term monitoring to survey the abun-dances of cereal aphids and their natural enemies in winter wheat. The research project focuses on the interactions of host plant and aphids in ecological crop rotation systems differing in their amount of legumes (nitrogen intensive, nitrogen extensive system). Additionally manure treated winter wheat plots established in both ecological crop rota-tion systems were investigated. For comparison the abundance of aphids in conventional farming systems with winter wheat fields nearby were also monitored. The results indi-cate that within the triannual investigation period, aphids significantly... |

| Soil dwelling pest species are difficult to control because of their cryptic life style and their unpredictable distribution belowground. The efficacy of biological control agents is limited, mainly because of low rhizosphere competence. Here we propose to use a strategy where pest are attracted to killing agents instead of bringing killing agents to the pest. We developed capsules emitting carbon-dioxide which are combined with an specific isolate of an entomopathogenic fungus or Neem. The principle of an attract & kill strategy takes advantage of the behaviour of soil dwelling larvae which use CO2 for locating their host plants. Components used for the production of the capsules are just contain biologically derived substances and therefore do not... |
