Abstract
Sbebab A. Hossni. " Ecological and biological studies on different aphid species infesting some legume plants in Egypt" Unpublished M. Sc. Thesis, Zagazig University, Benha Branch, Fac. of Agric., Department of Plant Protection, 2004.
The present work was carried out at Sids A.R.S., Beni-Suef Governorate during a period from 1998/99 to 200112002 growing seasons.
Different species of aphids were surveyed in five cool-season food legumes including faba bean, lentil, chickpea, fenugreek and peas. Six aphid species were surveyed on faba bean plants Aphis craccivora, A. fabae, A. gossypii, Acyrthosiphon pisum, Myzus persicae, Smynthurodes betae. Four aphid species were found to infest lentil plants, being Aphis craccivora, A. pisum, A. fabae, S. betae. Only two species of aphid were recorded on chickpeas were A. craccivora and Acyrthosiphum pisum. Three aphid species were sheltered fenugreek plants A. craccivora, A. fabae and A. pisum. Three species•of aphids were recorded on pea plants namely A. craccivora, A. fabae and Acyrthosiphon pisum.
Population density and seasonal abundance of cowpea aphid, Aphis craccivora and their associated predators on faba bean were estimated throughout two successive seasons 1999/2000 and 2000/200 I.
Some agricultural practices, such as effect of plant distribution and densities, planting dates and crop variety on the population abundance of A. craccivora infesting
• faba bean and its ability yield production were studied throughout two successive seasons of 1999/2000 and 2000/200 I.
Different biological aspects of A. craccivora reared on faba bean; cowpea and common bean were carried out for three generations under insectary conditions (24 ±
2 °C and 55 ± 5 % R.H.), during 2002.
• The potential applications of four rates of Gaucho (Imidacloprid) a novel systemic insecticide used as seed coated before crop cultivation in order to suppress early aphid attack and crop yields potentiality were carried out during 2000/200 I and
2001/2002 growing seasons.
Key words: Survey, Ecology, Biology, Aphids, Faba bean, Lentil, Chickpea, Fenugreek, Pea, Cowpea and Common bean.
