| Abstract: | The functinal response of the third instar larva of chrysopa septempunctata wesmael to the density of Aphis citricola conforms to the Holling's disc equation when the density of Aphis citricola is above 20 phids per shoot. When the density of aphid is Below or epual to 20 aphids per shoot, the aphids will be predated entirely. The instar larva of chrysopa septempunctata had strong searchign and predatory abilites for Aphis citricola. When aphids are enough, the predeated aphids per C. septempunctata in 24 hours are above 200. Although only one aphid per shoot is existed,C. septempunctata can predeted it 24 hours. |
