Systemic imidacloprid affects intraguild parasitoids differently

Data taken on parasitism rates in H. virescens larvae by T. nigriceps and C. sonorensis in flue-cured tobacco treated with and without systemic applications of imidacloprid in Edgecombe County and Lenoir County, North Carolina (2012-2013). Parasitism rates for field and greenhouse trials are presented. Included are imidacloprid and metabolite concentrations (in ppb) in field-collected H. virescens larvae, T. nigriceps larvae and T. nigriceps adults. Also included are imidacloprid and metabolite concentrations in H. viresecens larvae parasitized by T. nigriceps or C. sonorensis and fed on imidacloprid treated or untreated plants in greenhouse trials.
