Lethal and Sublethal Effects on Tamarixia triozae (Hymenoptera: Eulophidae), an Ectoparasitoid of <i>Bactericera cockerelli</i> (Hemiptera: Triozidae), of Three Insecticides Used on Solanaceous Crops

Lethal and sublethal effects of refined soybean oil, imidacloprid, and abamectin on <i>Tamarixia triozae</i> (Burks; Hymenoptera: Eulophidae) were assessed after exposure of the eggs, larvae, and pupae of this parasitoid to three concentrations of these active substances: the LC<sub&g...

description Lethal and sublethal effects of refined soybean oil, imidacloprid, and abamectin on <i>Tamarixia triozae</i> (Burks; Hymenoptera: Eulophidae) were assessed after exposure of the eggs, larvae, and pupae of this parasitoid to three concentrations of these active substances: the LC<sub>50</sub> for fourth-instar <i>Bactericera cockerelli</i> (Sulc.; Hemiptera: Triozidae)and 50% and 100% of the minimum field-registered concentration (MiFRC). Soybean oil caused 26-61% mortality in <i>T. triozae</i> 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 <18% mortality of <i>T. triozae</i> pupae, with the exception of the abamectin 50% (47%) and 100% (72%) MiFRC. The mortality of larvae and pupae derived from treated eggs was ≤39% for all three insecticides, and that of pupae derived from treated larvae was ≤10%. In general, emergence of adults developed from treated eggs, larvae, and pupae was affected more by abamectin than by the other treatments. The proportion of females derived from all three development stages was not affected by treatment with the compounds, except when the parasitoid was treated as larvae with the soybean oil 100 and 50% MiFRC (66 and 68%, respectively) or when treated as pupae with the imidacloprid LC<sub>50</sub> and 100% MiFRC (~60%). Female longevity was generally higher than that of males. The use of imidacloprid, soybean oil, and abamectin in combination with <i>T. triozae</i> for pest control may be effective when the parasitoid is in the pupal stage because this stage is less susceptible than other immature stages.
