Evaluation of Artemisia absinthium L. Essential Oil as a Potential Novel Prophylactic against the Asian Citrus Psyllid Diaphorina citri Kuwayama

Interest in developing novel crop protectants has increased the recent decade due to harmful effects of synthetic pesticides on humans and environment. Diaphorina citri threatens citrus industry worldwide is primary vector phloem-limited bacterium (HLB). However, there no available cure for HLB. management mainly depends use insecticides, but their massive application leads resistance pest populations. Therefore, alternative strategies are needed. Our results indicated that fewer D. adults settled plants treated with AAEO than control 48 h after release. The psyllids fed leaves significantly reduced honeydew production compared control. showed potent ovicidal activity against eggs LC50 5.88 mg/mL. Furthermore, we also explored fitness AAEO-treated untreated Citrus sinensis by using two-sex life table tools. revealed intrinsic rate increase (r) was higher seedlings (0.10 d−1) those an LC20 concentration (0.07 d−1). Similarly, net reproductive (R0) (14.21 offspring) (6.405 offspring). were safer Aphis mellifera, 35.05 mg/mL, which relatively 24.40 mg/mL values citri. indicate exhibits toxic behavioral citri, can be a potential candidate managing this pest.
