Results conducted show that the best oil gives the lowest average of eggs for adult and percentage of production was Nigella sativa oil with an average of 46.51 eggs /female and 47.41 % respectively . on one hand Cyperus rotundus oil has the best oil effect on the number of emergencys insect and gives a lowest percentage of damage and lowest effect on seeds germination with an average of 30.27 insects , 13.99 % and 98.99 % respectively . On the other hand the oil of Foeniculm vulgare gives the least effect on average of eggs / female , number of emergency insects percentage of production adult , the lowest percentage of damage and higher effect on percentage of seeds germination with an average of 87. 38 eggs /female , 67.49 insect /female , 27.66 % and 92.22 % respectively | ||
