Abstract
The sorghum shoot fly, Atherigona soaata Rondani, attacks sorhgum ratoon (Sorghum bicolor (L.) Moench) at Sids and AI-Aiat with Arnerigona humeralis(VViedemann) on Sudan grass (Sorghum vu&tare var. sucranense Hitch.) and Adietigona bedfordi Emden (new record) on Barnyard grass (EchInochloa onus-galli (L) P. Beauv) at Alaiat in Middle Egypt. The shoot flies were generally active during the year and passing from crop to crop. It infested ratoon of sorghum plants left in the field after harvest reaching about 12% at Sids in 2002. Infestation was lower (about 5%) on Barnyard and Sudan grasses at Al-Aiat in 2002-2003 and 2003. Larvae peaked by early January on Barnyard grass and at early and late July as well as the third week of August on Sudan grass at AIAiat. Two peaks were attained by the third week of November and the second half of December on infessted sorghum ratoon at Sids. Flies emerged from infested plants of the forage crops during the most months in the year. Flies reared from larvae infested Barnyard and Sudan grasses peaked on late January, July and August and December. Larval parasitism was higher (about 61% ) on Barnyard and lower (about 9%) on Sudan grass at Al-Aiat. While pupal parasitism was (about 6%) on Sudan grass and reach the lowest rate (about 1%) on both larvae and pupae on sorghum ratoon at Sids. Three hymenopterous larval parasitoids i. e. Neotrichopavides sp. near nyemitawus Rohwer, Paliobius sp. and Pnigalio sp. (Eulophidae), two pupal parasitoids i. e. aditula sp. (Ptromalidae) and Dacnusa sp. (Braconidae) and one undetermined hyperparasitoid belongs to Cynipidae had emerged These species are newly recorded on A. soctata in Egypt. The first and the second species were abundant on larvae infested sorghum ratoon or Barnyard grass at Al-Aiat and on sorghum ratoon or Sudan grass at Sids and Al-Aiat Plowing sorghum fields and collecting stubbles could be useful as a cultural control method for decreasing the population size of the sorghum shoot fly
