Psyllids feeding on treated plants may ingest antimicrobials, which may have the potential to harm psyllids due to their reliance on bacterial endosymbionts for survival. Antimicrobial treatments may negatively affect a variety of psyllid biological features, including fecundity, transmission capacity, life span, developmental time, and behavior.� The current objective was to evaluate the effect of dietary exposure to antibiotics on�D. citri�survival in a greenhouse bioassay. Feeding solutions containing oxytetracycline (Fireline) or streptomycin (Firewall) were orally administered to�D. citri. D. citri mortality was significantly higher when insects fed on artificial diet solutions containing 1mg ml-1 oxytetracycline, 5mg ml-1 oxytetracycline, or imidacloprid. Approximate 40% and 100% mortality occurred among�D. citri that fed on 5 mg ml-1 of oxytetracycline after 3-d and 10-d, respectively. Greater mortality occurred in response to the high oxytetracycline concentration than the low concentration on day 3 (25%) and day 10 (63%).�� D. citri mortality in response to untreated diet was approximately 20% and 30% on days 3 and 10, respectively. Neither 5 mg ml-1 nor 1 mg ml-1 streptomycin exhiwas associated with significant�D. citri mortality as compared with untreated diet. After 30d, 40% of�D. citri that fed on untreated or streptomycin diets survived. Subsequent assays will evaluate the effect of foliar applied antimicrobial treatments on�D. citri survival and CLas transmission.�
