| Description
| - Spatial distributions of pea aphid (Acyrthospihon pisum) and its natural enemies in field peas (assessed in large field trials in the Czech Republic during 2008 - 2012, project NAZV: QH82027) were influenced by the way of growing the crop. In field pea monocultures the aphids tended to aggregate into clusters significantly more. Especially that was well apparent when insecticides were applied into the crop some time (mostly 14 days) before the beginning of pea aphid fly activity. There was easy to localize patch clusters (they were indicated by the values of aggregation Indices Ia and Ja, p < 0,05), usually more than one per field, with differently large areas and with different distances one another. In patch clusters (focuses) the infestation of plants were increasing intensively in time and the infestation extended across the whole crop from them. The distributions of aphids in field peas intercropping with spring cereals were more uniform (Indices of aggregation, Ia, were usually smaller than unity), aphids had weaker tendency to create significant clusters and clear focuses of infestation in the crop and their population growth were less dramatic. The distributions of pea aphids and their natural enemies were significantly associated only in field peas intercropped with spring cereals. Field pea growing in monocultures and also using of insecticides had clear negative effects on spatial and temporal associations between distributions of pea aphids and their natural enemies in crops. Pea aphid´s predators and parasitoids were able to find their host significantly earlier (temporal view) and more effectively (spatial view) in field peas intercropping with spring cereals compared to field peas monocultures (with or without insecticides).
