SURVEY AND SEASONAL ABUNDANCE OF MAJOR INSECT PESTS ATTACKING RICE PLANTATION

Abstract
Survey and seasonal abundance of major pests attack and damaging rice plants (Giza 171 , variety) in nursery and fields by using light trap and sweep net were carried out during 2003 and 2004 seasons at Faqus district, Sharkia Governorate.
Results of survey in both seasons revealed that the collected insects were 26 species belonging to 26 genera as well as one undefined species belonging to genus Chironomus of these , 12 species from Homoptera, four species from Diptera; four species from Lepidoptera; three species from Hemiptera and four species from Orthoptera. These orders could be arranged descendingly according to their abundance during the whole period of study as follows Homoptera, Diptera, Lepidoptera, Hemiptera and Orthoptera which recorded 85.13; 8.38; 2.90; 2.76 and 0.83% , respectively.
Accordingly seasonal abundance of some major economic importance insects found in large numbers and / or approximate period of abundance were, homopterous species such as: Nephotettix modulatus, (late June up to late Oct.), Sogatella furcifera (late July up to late Oct.) and Balclutha hortensis (late June up to late Oct.). Yet dipterous species including Chironomus sp. (early June up to early Oct.) and Hydrellia prosternalis (late June up to early Oct.) then, the lepidopterous species including Chilo agamemnon (late June up to late Oct.).
All the surveyed dominant species were peaked in field except bloodworm Chironomus sp. which reached its peak in nursery.
A relationship between insect population of each species and climatic factors (Temperature and relative humidity) were noticed in most cases.
Key words: Rice–light trap and sweep net–major insect pests- population fluctuations.
