Lethal and sublethal effects of refined soybean oil, imidacloprid, and abamectin on Tamarixia triozae (Burks;Hymenoptera: Eulophidae) were assessed after exposure of the eggs, larvae, and pupae of this parasitoid to three concentrations of these active substances: the LC50 for fourth-instar Bactericera cockerelli (Sulc.; Hemiptera: Triozidae)and 50% and 100% of the minimum field-registered concentration (MiFRC). Soybean oil caused 26?61% mortality in T. triozae eggs and 6?19% in larvae; mortality in both eggs and larvae was ≤19% for imidacloprid and 4?100% for abamectin. All three compounds caused
