| Abstract | ||||
| This study was carried out to evaluate some compounds (Crater; Baiocao and Achook) against aphid insect (Aphis craccivora) and its predator Coccinella undecimpunctata) on some plants,( green mint; pepper mint; dill and thyme plants) with different concentrations under laboratory conditions and EL-Fayoum Governorate during the seasons 2007 and 2008. The results were obtained,directy before spraying as a pre-count and then after 1, 3, 5 and 7 days as a post count at field and after 24 hr at laboratory. Crater was the most effective compound against aphid individuals, followed by Baicao and Ashook on some plants,( green mint; pepper mint; dill and thyme plants). Baicao was the most effective compound against the predator Coccinella undecimpunctata) on some plants,( green mint; pepper mint; dill and thyme plants) . The mean general reduction of aphid individuals could be arranged as follows Crater (89.47;90.2;87.5 & 88.3%) at 0.6 ml\l( 80.61;82.1;79.9 &80.5%) at 0.3 ml\l and( 73.66;70.9;75.1 72.6%) at 0.1ml\l while Ashook (81.53;80.0;77.9&79.9%) at 3.7 ml\l( 59.88;60.2;58.6 &57.8%) at1.8 ml\l ( 58.40 ;55.9 ;56.8& 58.1%) at 0.9 ml\l) on different plants,( green mint; pepper mint; dill and thyme plants) respectively, during the first seasons. The results obtained during season 2008 were the same season 2007. | ||||
