Mohamed Shahan Mahmoud;
Abstract
Ecological studies were carried out at the Entomology laboratory of the Faculty of Agriculture at Kafr El- Sheikh, Tanta University and the experimental farm of Rice Research & Training Center (RRTC), during two successive seasons of 2003 and 2004.
1. Survey insect pests and their natural enemies inhabiting rice field l.l.Survey by different traps:
This study was conducted at the experimental farm of Rice
Research & Training Center during two successive seasons; 2003 and
2004. An area of ten feddans. was prepared for this study, and sown by Sakha I 0I rice variety on May 5th 2003 season and on May I Oth 2004 season. All recommended agricultural practices were followed during the growing season without insecticide applications. Samples were initiated for every season two weeks after planting and continued every week until harvest using different sampling methods. The conducted experiments and main results could be summarized as follows:
1.1.1. Sweep net:
From the current study, 53 insect species were recorded, belonging to 32 families and 13 orders by sweep net. The recorded insects were classified into two main groups: pests (30 species, 17 families and 9 orders) however II of them are insect visitors (belonging to 9 families and 6 orders), natural enemies (17 predatory species, belonging to 13 families and 9 orders and 7 parasitoid species belonging to 3 families and only one order).
1.1.2. Photoelector:
The surveyed insects were 52 species of insects belonging to 30 families and I 0 orders. These insects could be divided into two groups.
