Abstract: This work was carried out at Mallawi Agricultural Research Station Farm, El-Minia Governorate on cotton plants during 2003 and 2004 cotton seasons . The present work aimed to shed light on the natural enemies associated with Bemisia tabaci ( Genn.) and Aphis gossypii (Glover ) infesting cotton fields and its role of suppression of these insects .
The obtained data showed that :
1-Two hymenopterous species Encarsia lutea (Masi) and Eretmocerus mundus Mercet (family: Aphelinidae) were identified as parasitoids of Bemisia tabaci. The population of En Luta Masi. was higher than Eret. mundus Mercet during the two seasons . Parasitoids on A gossypii were nil during the present investigation.
2-The predators species during this survey were predacious mite Amblyseius swirskii , true spiders and predacious insects (Coccienlla undecimpunctata , Coccienlla septempunctata , Cydonia vicina , Coccienlla tridecimpunctata , Scymnus syriacus, Scymnus interruptus, Chrysopela carnea , Onus albidipennis , Orius leavigatus , Camplyomma nicolas put., Peaderuis alfierii and Syrphus corollae ) .
