| Abstract:
Cultivation of caraway, Carum carvi, is concentrated mainly in upper Egypt, but has recently been introduced to the Nile delta. Field and lab investigation showed a severe attack by different insects especially in the early vegetative growth period. Pit-fall traps were used to determinate population densities of pests and natural enemies and the Absolute Importance Value (AIV) was estimated for each component. The results show that the most important insects were Tropinota squalida (Coleoptera) with AIV 3.89 followed by Lepidoptera larvae 3.45 and Messor sp. (Forinicidae) 2.99 respectively. The highest importance values were recorded for 4 associated natural enemies: spiders (Arachnidae) with AIV 4.71, Carabidae 3.51, Labidura riparia (Lapiduridae) 2.42 and Surphus corolla (Diptera) 3.22 respectively. Correlation analysis showed, that caraway was similar to lettuce, okra and cabbage concerning the natural insect fauna. | |
