| Abstract | ||
| Liriomyza trifolii (Burgess) is one of the major insect pests on faba bean in Egypt. The efficacy of seed and foliar treatments of neonicotinoid insecticides in comparison with sulfoxaflor were evaluated for control of leafminer during 2021-2022 and 2022-2023 seasons. Seed treatments of sulfoxaflor, thiamethoxam and imidacloprid reduced leafminer on faba bean variety compared with the control during both seasons. However, acetamiprid and dinotefuran had lower effects as seed treatments. Furthermore, sulfoxaflor exhibited the highest reduction on faba bean leafminer. In addition, the foliar treatments of sulfoxaflor, thiamethoxam, imidacloprid, acetamiprid and dinotefuran significantly reduced the population of leafminer with an average reduction percentage of 82.41, 74.11, 66.13, 56.04 and 49.12%, respectively during the first season. In the second season, the average reduction was significant difference between sulfoxaflor 77.97% and thimathoxam 66.45%, imidacloprid 61.37%, acetamiprid 50.98% and dinotefuran 43.66%. Under faba bean field conditions, sulfoxaflor, thiamethoxam, imidacloprid, acetamiprid and dinotefuran registered a significantly high percent reduction of the faba bean leafminer at 1, 3, 7, 15 and 21 days post treatment. Therefore, sulfoxaflor as foliar and seed treatments could be used in integrated pest management programs for controlling leafminer. Both treatment methods have demonstrated efficacy against L. trifolii in faba beans. | ||
