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:
- 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.
- 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 , Orius albidipennis , Orius leavigatus , Camplyomma nicolas put., Peaderuis alfierii and Syrphus corollae ) .
