“…In general, the application of Si treatments (either foliar, soil, or soil + foliar) reduced ACP oviposition in citrus seedlings around 60%. Short-term studies (4 weeks) carried out by Miranda et al (2017) with foliar spraying of insecticides (rotation of neonicotinoid, organophosphate, and pyrethroid chemical groups) showed a control around 80% of ACP adults. Ram ırez-Godoy et al (2018) found that foliar calcium carbonate sprays (a biorational insecticide) affected ACP oviposition negatively at around 60%.…”

ADDITIONAL INDEX WORDS. Diaphorina citri, foliar silicon concentration, integrated pest management, plant herbivory, sucking insects, host defense mechanisms SUMMARY. Asian citrus psyllid [ACP (Diaphorina citri)] is one of the most serious threats to the global citrus (Citrus sp.) culture, and management of ACP has depended primarily on the application of chemical insecticides. The expression of resistance mechanisms to herbivory is a key component in integrated pest management in crop production in which silicon (Si) applications can play an important role in plant-insect relationships. The objective of the current study was to evaluate the application of Si to tahiti lime (Citrus latifolia) plants under natural infestations of ACP. Two experiments were conducted using 15-month-old seedlings and 2-year-old trees, respectively. Treatments were 1) foliar Si sprays (potassium silicate) at a dose of 2 mLÁL -1 , 2) soil Si application at a dose of 1 kg commercial product per plant, 3) combined soil and foliar applications of Si at the doses just listed, and 4) untreated plants (control). The application of Si treatments to both seedlings and trees affected ACP oviposition, causing a reduction of 60%. Applications of Si did not affect the nutritional status (macronutrients and micronutrients) of plants in either test, except that the foliar concentration of Si tended to be greater in the soil and soil D foliar treatments than in the other treatment in both seedlings and trees. Based on these results, we suggest that Si can be added as a component of ACP integrated pest management programs.

“…Whenever significant F ‐values were obtained, treatment means were separated using Tukey's test ( p < 0.05). D. citri is known to have an aggregated behaviour (Sétamou et al., ), thus the frequency of adult detection on traps is considered a useful additional parameter to evaluate the effectiveness of control method (Miranda et al., ). The percentages of traps with positive D. citri detection were calculated for each sampling period and compared using a log‐likelihood ratio test.…”

Citrus grove colonization by the Asian citrus psyllid (Diaphorina citri) starts from border trees. This behaviour can be exploited by placing barriers along grove borders to prevent psyllid incursion and thwart population establishment and growth. We tested the effects of psyllid‐resistant mesh fencing along grove borders for season‐long control of D. citri populations. Deployment of sticky cards at different heights revealed that most D. citri (>99%) were collected on traps placed at or below 3.7 m along grove border. Thus, psyllid‐resistant mesh fencing (3.7 m in height) was installed along the eastern and southern borders of a 3‐year‐old grapefruit grove to protect against D. citri infestations, while the west and north edges were left unprotected. A similar adjacent grove with no border fencing served as untreated control. A reduction of 55%–98% of D. citri numbers was observed in the grove with border fences relative to the untreated control. D. citri density reductions were more pronounced on the sides with border fences suggesting that the observed effects were due to the mesh fencing. Thus, border mesh fencing as a standalone approach or coupled with other management strategies, such as border sprays, could be an effective psyllid management strategy. The season‐long benefits of border fences are not limited to D. citri population control, but also significant reductions of insecticide input and nontarget effects, thus substantially mitigating the risks of secondary pest outbreaks and ensuring the sustainability of D. citri management in citrus groves.

Diaphorina citri mainly damages the new shoots of citrus plants.…”

Background. Citrus huanglongbing (HLB) is a destructive disease of citrus and a major threat to the citrus industry around the world. This disease accounts for substantial economic losses in China every year. Diaphorina citri Kuwayama is one of the major vectors by which citrus HLB is spread under natural conditions in China. Research is needed to identify the geographic distribution of D. citri and its major areas of occurrence and to formulate measures for early warning, monitoring and control of this pest and citrus HLB. Methods. In this study, the ecological niche modelling software MaxEnt (maximum entropy model) was combined with ArcGIS (a geographic information system) to predict the potential geographic distribution of D. citri in China. Key environmental factors and the appropriate ranges of their values were also investigated. Results. Our results show that the training data provided a good forecast (AUC mean = 0.988). The highly suitable areas for D. citri in China are mainly concentrated to the south of the Yangtze River, and the total area is 139.83×10 4 km 2. The area of the moderately suitable areas is 27.71×10 4 km 2 , with a narrower distribution than that of the highly suitable area. The important environmental factors affecting the distribution of D. citri were Min Temperature of Coldest Month, Mean Temperature of Coldest Quarter, Precipitation of Wettest Quarter, Mean Temperature of Warmest Quarter, Precipitation of Warmest Quarter, Max Temperature of Warmest Month, and Temperature Seasonality. These results provide a valuable theoretical basis for risk assessments and control of D. citri. Discussion. The predicted results showed that there were highly suitable areas for D. citri in Chongqing, Hubei, Anhui and Jiangsu. Therefore, the possibility exists for the further spread of D. citri in China in the future. Extreme temperature variables, especially the Min temperature of the coldest month, play an important role in the distribution of D. citri and are most closely related to the distribution of D. citri.
