“…The success of these insecticides is due in part to their broad spectrum of efficacy, systemic action in the plant, long residual activity and application versatility (e.g., foliar, trunk, and soil) 12 . However, extensive use of neonicotinoid insecticides has resulted in the development of resistance in populations of D. citri 13 . Furthermore, the several governments, including Canada and the European Union, have restricted the use of neonicotinoids owing to concerns about unintended environmental consequences associated with their usage (e.g., toxicity to pollinators and non‐target insects).…”

BACKGROUND Chemical control is the most used and effective method to control Diaphorina citri, the vector of the phloem‐limited bacteria associated with citrus huanglongbing (HLB) disease. The objectives of this study were to determine the effectiveness of flupyradifurone applied via dripping irrigation systems on D. citri. Bioassays were conducted using leaves harvested on various dates post treatment, and insecticide residue in leaf tissue was quantified. RESULTS The drip application of flupyradifurone on citrus trees provided high‐level and long‐term control against D. citri adult, and the median lethal concentration (LC50) for ingestion of flupyradifurone in D. citri was 22.22 mg kg–1 (fresh leaf). Flupyradifurone residue was detected in leaf tissue within 3 days after treatment. The measured level of flupyradifurone peaked on day 40 day after application, and then showed a steady decline in subsequent days for all three applied dosages. The amounts of flupyradifurone in upper, middle, and lower leaves were similar, and trends in the change in concentration of flupyradifurone were consistent. CONCLUSIONS The results demonstrate that flupyradifurone can be a valuable new tool for D. citri management programs, and drip‐applied flupyradifurone provides an extended period of control efficacy. This paper could provide a reference to reduce the dependence on foliar‐applied insecticides, with associated benefits for non‐target exposure to workers and pollinators. © 2021 Society of Chemical Industry

“…Scirtothrips dorsalis has developed resistance to monocrotophos, acephate, dimethoate, phosalone, carbaryl, and triazophos in India [17]. In another study, S. dorsalis showed no or very low level of resistance against organophosphates (acephate, chlorpyrifos, quinalphos, and dimethoate), neonicotinoids (thiamethoxam, imidacloprid), and abamectin as measured by resistance ratio (RR) but showed 21-28 fold increase in RR to Spinosad 45SC probably due to multiple applications [18]. Moreover, frequent insecticide applications negatively affect non-target organisms that help to regulate thrips populations in blueberry plantings [19,20].…”

Scirtothrips dorsalis Hood is an invasive and foliar pest of Florida blueberry that reduces plant growth by feeding on new leaf growth. A sampling plan is needed to make informed control decisions for S. dorsalis in blueberry. Fourteen blueberry fields in central Florida were surveyed in 2017 and 2018 after summer pruning to determine the spatial and temporal distribution of S. dorsalis and to develop a fixed-precision sampling plan. A sampling unit of ten blueberry shoots (with four to five leaves each) was collected from one blueberry bush at each point along a 40 × 40 m grid. Field counts of S. dorsalis varied largely ranging from zero to 1122 adults and larvae per sampling unit. Scirtothrips dorsalis had aggregated distribution that was consistent within fields and temporally stable between summers, according to Taylor’s power law (TPL) (aggregation parameter, b = 1.57), probability distributions (56 out of 70 sampling occasions fit the negative binomial distribution), Lloyd’s index (b > 1 in 94% occasions), and Spatial Analysis by Distance IndicEs (31% had significant clusters). The newly developed fixed-precision sampling plan required 167, 42, seven, or three sampling units to estimate a nominal mean density of 20 S. dorsalis per sampling unit with a precision of 5%, 10%, 25%, or 40%, respectively. New knowledge on S. dorsalis distribution will aid in evaluating the timing and effectiveness of control measures.
