THE BIOLOGICAL EFFECT OF TOTAL AND PARTIAL EXTRACTS OF LEAVES FOR TWO SPECIES OF POPLAR TREES ON Chaitophorus Versicolor NYMPHS

| description | This study included one type of forest insect in the Nineveh of northern Iraq, which is plant sap suckers that infect a group of forest trees, including Populus Euphratica and P.deltoides. The results showed a variation in the killing rate resulting from treating poplar leaf nymph aphids with phenols of the study tree species according to the type of tree, concentration, and insect phase. The phenols of the Euphratica poplar leaves excelled on average, with the killing rate of the American type being 62.01 and 56.49% at a concentration of 10%, respectively. For Alkaloids, it was 47.21 and 43.3% for P.euphratica and P.deltoides, respectively. Meanwhile, terpenes were 43.21 and 37.69%. The average percentage of expulsion reached 36.89% in the nymph phase of P. euphratica at a concentration of 10%. The study showed significant superiority of the Alkaloids of Euphratica poplar and the average expulsion percentage over the Alkaloids of the other types. The average percentage of expulsion was 32.69% in the nymph phase at a concentration of 10%. The Euphratica poplar Terpenes outperformed the average kill rate over the Terpenes of the other type, with an average expulsion ratio of 29.92% in the nymph phase at a concentration of 10%. |
