Abstract

This research was conducted to study the biological control of some  piercing sucking insect pests infesting common bean plants under  open field and greenhouse conditions using biofertilizers and biocides as well as the release of the predator , Coccinella undecimpunctata L. (Coleoptera: Coccinellidae). Experiments were carried out during the Winter and Spring seasons of 2012, 2013 and 2014 years at a private farm and greenhouse at Elmenoufia Governorate, Egypt. The collected samples were examined at the Biological Laboratory of Economic Entomology and Agricultural Zoology of the Faculty of Agriculture, Menoufia University.

The aim of the study is to maximize the use of bio fertilizers; biopesticides; insect predators; resistant varieties and planting time in the control programs as well as in the integrated management programs of some piercing sucking vegetable pests in open fields and plastic houses.
The obtained results indicated that the application of Nitroben, phosphorin, poultry manure, compost and the predator, Coccinella undecimpunctata, significantly controlled aphid and white fly stages infesting common bean plants under open field and greenhouse conditions to prevent the random application of different chemical pesticides which destroy and pollute our environment.
