“…Insecticide susceptibility is known to vary among different life stages and among different body (abdomen) color morphs of the same life stage of ACP and cotton whitefly, Bemisia tabaci (Gennadius), owing to differences in feeding behavior, total protein content and activity levels of detoxifying enzymes . Although experiments with nymphs and adults are not directly comparable owing to differences in endpoint observation, in general, ACP nymphs were more susceptible to pymetrozine than adults on potted plants sprayed with pymetrozine at the labeled rate (52 mg L −1 ) . Eggs of ACP were more susceptible to buprofezin and diflubenzuron than nymphs, while fourth‐instar nymphs were less susceptible to carbaryl, chlorpyrifos, fenpropathrin and spinetoram than adults .…”

By 2014, huanglongbing (HLB), the most destructive disease of citrus, and its insect vector, the Asian citrus psyllid (ACP), Diaphorina citri (Kuwayama), became established in all major citrus-growing regions of the world, including the United States, with the exception of California. At present, application of insecticides is the most widely followed option for reducing ACP populations, while application of antibiotics for suppressing HLB disease/symptoms is being practiced in some citrus-growing regions. Application of insecticides during the dormant winter season, along with cultivation of HLB-free seedlings and early detection and removal of symptomatic and asymptomatic trees, has been very effective in managing ACP. Area-wide management of ACP by application of insecticides at low volume in large areas of citrus cultivation has been shown to be effective in managing HLB and reducing management costs. As insecticide resistance is a major problem in sustainable management of ACP, rotation/alternation of insecticides with different chemistries and modes of action needs to be followed. Besides control of the insect vector, use of antibiotics has temporarily suppressed the symptoms of HLB in diseased trees. Recent efforts to discover and screen existing as well as new compounds for their antibiotic and antimicrobial activities have identified some promising molecules for HLB control. There is an urgent need to find a sustainable solution to the HLB menace through chemical control of ACP populations and within HLB-infected trees through the judicious use of labeled insecticides (existing and novel chemistries) and antibiotics in area-wide management programs with due consideration to the insecticide resistance problem.

“…Currently the world's main producer of Mexican lemon fruit, the Apatzingán Valley, with an area of 45715 ha, is responsible for 60% of the total national production . Since its detection in Mexico, chemical control through the use of pyrethroids, organophosphates, neonicotinoids, and spynosin insecticides remains the most practical method for reducing populations of D. citri . However, as a consequence of extensive application schedules and, in some cases, repeated sequential use of the same insecticide or products with the same mode of action, this approach is producing unsatisfactory results, with the development of variable levels of resistance…”

“…In addition to the direct effects of afidopyropen on population growth, sublethal concentrations may also reduce the rate of transmission of Candidatus Liberacter bacteria between citrus hosts as a consequence of reduced D. citri feeding. This hypothesis warrants further investigation; however, reduced pathogen transmission by D. citri caused by sublethal insecticide exposure has been demonstrated previously (Boina et al 2011). Exposure to sublethal insecticide concentrations is known to cause physiological changes that reduce development and fecundity and lead to an overall fitness decline in certain insect species (Harnoto et al 1984;Luckey 1968;Omer and Leigh 1995;Stark and Banks 2003).…”

A relatively new insecticide chemistry for controlling sucking insects, afidopyropen, was investigated for toxicity against Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae). We evaluated the mortality of D. citri eggs, nymphs, and adults treated with afidopyropen using both laboratory-reared and field populations. We also quantified the effects of sublethal doses of afidopyropen on D. citri feeding, host choice selection, and fecundity. For laboratory susceptible adults, the contact LC 50 , topical application LD 50 , and leaf dip LC 50 were 2.13, 2.00, and 3.08 ng/µL, respectively. For adults collected from a commercially managed citrus grove in Florida, the contact LC 50 , topical application LD 50 , and leaf dip LC 50 were 1.37, 1.92, and 4.89 ng/µL, respectively. Egg hatch was significantly reduced following exposure to afidopyropen at 100 ng/µL. Furthermore, afidopyropen reduced D. citri nymph survival and adult emergence at concentrations ranging between 0.01 and 100 ng/µL. Diaphorina citri adult feeding decreased on citrus leaves treated with afidopyropen in a concentration-dependent manner as measured indirectly by honeydew excretion, and appeared almost completely inhibited after treatment with 10 and 100 ng/µL solutions of afidopyropen. In choice tests, significantly fewer D. citri adults settled on afidopyropen-treated plants than on control plants at 24, 48, and 72 h after release, with no differences in settling between males and females. Afidopyropen reduced the fecundity of D. citri in a concentration-dependent manner. Collectively, the results suggest that afidopyropen could contribute to the integrated management of D. citri and may therefore be useful in rotational programs to improve resistance management.
