| Inhoud: |
Changes of 0, 20 and 35% of NH4+ compared to N (NH4++NO3–) nutrient solutions of Lycopersicum esculentum L. cultivated on inert media on the multiplication of Macrosiphum euphorbiae (Aphididae Homomptera) were tested. The use of 0% NH4+ decreased 12% the fertility of aphids compared to 20% NH4+ and 17% compared to 35% NH4+. Reproduction of aphids on the leaves of flowering inflorescence increased 33% compared to that of the fruit setting inflorescence and 40% compared to that of the magnification inflorescence and 52% relative to the fixed level. The interruption of the fertilization of plant and its replacement by water for 4 days decreased 45% the fertility of aphids in the fourth inflorescence and 36% in the seventh inflorescence. |
