SURVEY AND RELATIVE OCCURRENCE OF INSECTS AND ASSOCIATED NATURAL ENEMIES ON FENUGREEK PLANTS AND STUDY EFFECT OF PLANT LEVEL ON ABUNDANCE OF INSECTS
Plant Protection Research Institute, Agricultural Research Center, Dokki, Giza, Egypt.
Abstract
The present investigation was carried out at the Experimental Farm of Plant Protection Research Station at Qaha,Qalyubiya Governorate throughout two successive seasons(2006 / 2007 and 2007 / 2008).The obtained results dearly indicated the following points: (1)-Tiventy three species of insects and associated natural enemies were surveyed on the fenugreek plant during two successive growing seasons . (2)- Thrips insect proved to be most abundant species during the two growing seasons showing the highest percent (50.27%) of grand total. (3)- It is worthy to mention that A. pis= among homopterous insects showed the highest relative occurrence comparing with the other homopterous insects (41.68 %.).(4)-The investigated orders were descendingly arranged according to occurrence rates as Thysonoptera, Homoptera, Diptera, Coleoptera, Hemiptera, Lepidoptera, Mesostigmata and Neuroptera . (5) It is worthy to mention that the individuals of aphid species berseem leaf weevil and cotton thrips were surveyed on terminal buds of fenugreek plant only and it is dear that lower leaves of plant were free from any individuals in both seasons. It mentioned that the lower leaves harboured the highest numbers of leafminer and whiteflies during two growing seasons.
