PHYTOPHAGOUS HETEROPTERA AND IFP - A SOLVABLE CONTRADICTION? |
| Author: | W. Klein |
| Abstract:
Every year phytophagous Heteroptera, especially Plesiocoris rugicollis (FALLÉN) and Lygus pabulinus L., cause more or less severe damages in apple orchards in the northern parts of Germany. One reason for an increasing number of Heteroptera damages in IFP is caused by the loss of registration for parathion-ethyl in this culture. The egghatch of the bugs usually starts at the beginning of blossom (cultivar ‘Boskoop’). In consequence the pesticides used against bugs should not be harmful to bees and effective against bugs. Synthetic pyrethroids fullfill these options but are harmful to different beneficial arthropods. The effects of different chemical treatments with IFP-pesticides, synthetic pyrethroids and pesticides of ecological fruit production on bugs and beneficial arthropods are demonstrated. | |
