| Abstract | ||||
| Larval parasitoids of the potato tuber moth, Phthorimaea operculella Zell. were surveyed in potato and tomato fields in Menofyia Governorate in 2003. Three species were found to attack P. operculella larvae infesting potato plants; the endoparasitoids, Apanteles litae var. operculellae Nixon and Diadegma molliplum Hlmgrn. and the ectoparasitoid, Bracon instabilis Marshal. Meanwhile, only B.instabilis was found to attack the larvae infesting tomato leaves. Percentages of parasitism in potato fields averaged 10.8, 5.6 and2.6 % by B.instabilis, A.litae and D.molliplum, respectively. The total percentages of parasitism by the three species ranged from 11.0 to 28.6 % with an average of 19.1 % in potato field, while it ranged in tomato fields from 0.0 to 21.4 % with an average of 11.1 % by B. instabilis | ||||
