| Application: | • Recruitment of Hippodamia variegata by active volatiles from Glycyrrhiza uralensis and Alhagi sparsifolia plants infested with Aphis atrata.: This research explores the role of butyl butyrate as a volatile compound in attracting predatory insects to plants infested with aphids. The study provides valuable insights into plant-insect interactions and the potential use of natural volatiles in integrated pest management (Jiang et al., 2024  ). |
