Integrated management strategies for control of cotton key pests in Middle Egypt
Agronomy Research 4 (special issue), 121-128
Abstract: In cotton production, there are many factors that can reduce crop yield. One important cause is insects. Insects that cause loss to the fruit are frequently more destructive than those that damage leaves, stems and roots. Cotton in Egypt is subjected to yield and quality losses by arthropod insects; losses extend to oil contents in the seeds. The cotton leaf worm (CLW), Spodoptera littoralis, the pink bollworm (cotton bollworm) (PBW), Pectinophora gossypiella and spiny bollworm (SBW), Earias insulana cause the greatest number of yield losses from nearly one million hectares cultivated annually.
This study describes an improvement in insect control practices directed against feeding insects (i.e., CLW, PBW and SBW) by integration of monitoring, biological control, cultural, behavioural and genetic aspects, and bio-insecticides that can serve as a basis for the formulation of a biologically-based new approach of integrated management of key cotton pests. Field studies were conducted during 2004 and 2005 at Minia Governorate, Middle Egypt. The experimental area was about 150 hectares of cotton (Giza-80). Five programs were evaluated. Percentages of infestations, cotton yield and population density of both natural enemies and sucking pests were used as criteria for evaluation of various programs.
