The predominant method for pest control has been the use of pesticides, which have been shown to have detrimental effects on soil, freshwater, and crop quality. Therefore, the development of novel and sustainable crop protection strategies has become increasingly imperative. In this study, a novel orange–red emitting Ba 2 SrWO 6 : Sm 3+ phosphor was synthesized using the high-temperature solid-state reaction. Under ultraviolet excitation, the phosphors showed obvious emission peaks at 575, 614, and 662 nm. The Ba 2 SrWO 6 : Sm 3+ was used to fabricate a fluorescence film with polydimethylsiloxane (PDMS), and attracted twice as many insects as the blank control group under 365 nm ultraviolet light. This material holds great potential as a fluorescent agent for insect trapping in the pest control fields of tea, cotton, eggplant, rice, potato, grape, and other agricultural industries. Our findings provide an eco-friendly approach to pest management for the increment of food production.

The objective of this work was to determine the best conditions for the use of synthetic sex attractants to monitor Illiberis pruni Dyar (Lepidoptera: Zygaenidae, Procridinae) in the Helan Mountain National Nature Reserve, Ningxia, China. Traps with binary blends of 2-butyl (7Z)-dodecanoate (300 µg) and 2-butyl (9Z)-tetradecanoate (300 µg) at a ratio of 1:1 caught the most moths. Catches were significantly different across 5–45 m inter-trap distances; the optimal trapping radius was 25 m. Trap height did not affect catches. The slope aspect, temperature, and humidity significantly influenced catches. More moths were caught as temperatures increased and relative humidity decreased. Traps placed on shady slopes caught significantly more moths than did traps placed on sunny slopes. This study elucidates how various factors influence the effectiveness of traps. The implications of these findings could facilitate safer and more environmentally friendly in situ management of I . pruni .

The attractiveness of a series of mixtures of (Z)-7-dodecenyl acetate (Z7-12:Ac), (Z)-9-tetradecenyl acetate (Z9-14:Ac), and (Z)-11-hexadecenyl acetate (Z11-16:Ac), the Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae) pheromone, were evaluated in four locations in China. The ternary blend of Z7-12:Ac, Z9-14:Ac, and Z11-16:Ac was the complete pheromone blend for A. ipsilon and the ratio of Z7-12:Ac and Z9-14:Ac was optimal at 3:1. The most attractive ratio of Z11-16:Ac to the other components depended on geographic location. The optimal ratio was 3:1:6 in Yunnan and Shanxi, 3:1:2 in Sichuan and ranged from 3:1:2 to 3:1:12 in Shanghai, which differs significantly from the ratio of 3:1:16 in Japan. The dose of the blend in the pheromone lure influenced attractiveness to male moths and was related to the temperature in the test locations. Attractiveness of sugar–acetic acid-baited and pheromone-baited traps to male and female moths was different before and after the start of flowering of the oilseed rape crop; large numbers of female moths were attracted to sugar–acetic acid traps before flowering but none after flowering had started. This was similar for male moths and there was no synergistic effect when sugar–acetic acid solutions and pheromone were used together. These studies suggest that pheromone trapping based on the blends of three components can be an effective tool to improve the efficiency of monitoring of this pest in China.

Simple SummaryHelopeltis cinchonaeis an economically important pest of tea plantations in Asia and has recently been reported in various provinces of China, expanding its population range. The bugs feed on growing shoots, sucking the sap and leaving the shoots susceptible to infection by fungi. No known control or monitoring tools have been developed forH. cinchonaeexcept for the excessive application of pesticides. The components of the sex pheromone produced by femaleH. cinchonaehave been identified and synthesized in previous work and have been shown to attract male bugs to traps. This is the first time that the components of the sex pheromone have been identified for a species ofHelopeltisbug. Here, we present the results of field trapping tests to optimize the blend of pheromone components, compare different types of traps, and determine the best position of the trap in order to maximize the catch of male bugs. Traps baited with the optimized lure were used to monitor populations of the bug and showed two distinct generations during the year. These results contribute to an environmentally-friendly approach to monitoring and managingH. cinchonaein the field.Helopeltis cinchonaeis an emerging pest of tea and causes severe damage to tea plantations in China. The female ofH. cinchonaehas been reported to produce a sex pheromone consisting of two components, hexyl (3R)-3-acetoxybutyrate and (5R)-1-acetoxy-5-butyroxyhexane, and lures containing the synthetic compounds have been shown to attract maleH. cinchonaeto traps in the field. This is the first time that components of the sex pheromone have been identified for a species ofHelopeltisbug, but their field application has not been evaluated in detail. The present study shows that a blend of both compounds loaded into a polyethylene vial at 0.2 and 2 mg, respectively, caught significantly more maleH. cinchonaebugs than the individual compounds and all the other tested blends. Sticky wing traps baited with the binary blend of compounds at the optimized ratio and dosage caught more bugs than bucket funnel or delta traps, and traps hung at a height of 10 cm above the tea shoots caught more bugs than those at other heights. The optimized traps and lures were used for monitoring the pest and two distinct population peaks ofH. cinchonaewere observed, the first one during mid-May to early June, and the other one in mid-September. Overall, the results of this study contribute to an environmentally-friendly approach to monitoring and managingH. cinchonaein the field.

Field studies using the synthetic sex pheromone of Trichophysetis cretacea , a trinary blend of ( Z )-11-hexadecenyl acetate ( Z 11-16:OAc), ( Z )-11-hexadecenal ( Z 11-16:Ald) and ( Z )-11-hexadecenol ( Z 11-16:OH), were performed in Sichuan to determine operational parameters for detection and control, such as dispenser type, blend ratio, dosage, and trap type, height and density. Of three pheromone dispensers tested, grey halo-butyl isoprene elastomeric septa were significantly more effective than polyvinyl chloride capillary tubing or silicone rubber septa. The ratio of the three components in the blend significantly affected moth catch. In the halo-butyl isoprene septa, the most effective ratio was 5 : 2 : 1 Z 11-16:OAc: Z 11-16:Ald: Z 11-16:OH. Sticky wing traps caught significantly more moths than water, noctuid moth or cone funnel traps. The most effective height at which wing traps were hung was 20 cm above the jasmine plants. Optimum trap density was 45 traps per hectare. Addition of volatile jasmine compounds did not increase the attractiveness of the sex pheromone. A dosage of 50 μg Z 11-16:OAc per lure was most effective in the autumn weather conditions of Quanwei. These data provide sufficient information to develop effective protocols for using the T. cretacea pheromone to detect and monitor this pest in the jasmine fields.

The sex pheromone of Phyllonorycter ringoniella (Matsumura) (Lepidoptera: Gracillariidae) has been identified to be a blend of ( Z )-10-tetradecenyl acetate ( Z 10-14:OAc) and E 4, Z 10-tetradecadienyl acetate ( E 4, Z 10-14:OAc) in Japan, Korea, and China. However, the commercial product based on previous results is not attractive enough to be used for monitoring and controlling apple leafminer populations in the field. We re-investigated the attractiveness of the two pheromone components, singly and in blends, in apple orchards in Shangdong and Shaanxi, the main apple-growing provinces in China. Our results revealed that Z 10-14:OAc alone was not attractive to P . ringoniella male moths in the field, but E 4, Z 10-14:OAc alone not only was strongly attractive but caught more males than any of the blends of Z 10-14:OAc and E 4, Z 10-14:OAc tested. The most attractive blend ratios differed slightly for the two locations. No clear dose–response relationship was obtained for the 2:8 blend of Z 10-14:OAc and E 4, Z 10-14:OAc. However, the dose–response field study of E 4, Z 10-14:OAc alone showed that 1 mg per lure achieved the highest moth catch. These findings differ from the previous report of the best pheromone blend in China. Our data showed that E 4, Z 10-14:OAc is the major component of the pheromone of P . ringoniella .

For successful pest management, codlemone (E, E-8,10-dodecadien-1-ol) is widely used to monitor codling moth. The pheromone release rate is essential for the lure’s attractiveness. The optimal sex pheromone release rate (V 0 ) for trapping codling moth was evaluated during 2013–2014. The overwinter generation V 0 was 6.7–33.4 μg wk −1 , and moth catches (MCs) were 0.82 ± 0.11 adults/trap/week; MCs for lower (V 1 ) and higher (V 2 ) release rates were 52.4% and 46.3%, respectively, of that for V 0 . The first generation V 0 was 18.4–29.6 μg wk −1 , with MCs of 1.45 ± 0.29 adults/week/trap. V 1 and V 2 MCs were 34.5% and 31.7%, respectively, of those for V 0 . Combining across generations, the final V 0 was 18.4–29.6 μg wk −1 , with MCs of 1.07 ± 0.06 adults/week/trap. V 1 and V 2 MCs were 51.4% and 41.1%, respectively, of that for V 0 . Overwinter generation emergence was relatively concentrated, requiring a wider V 0 . Maintaining the release rate at 18.4–29.6 μg wk −1 could optimize the lure’s efficacy; this resulted in the capture of nearly 1.9 and 2.4 times more moths than V 1 and V 2 , respectively. The results also indicate that a dispenser pheromone release rate of 200–300 times that of the female moth can perfectly outcompetes females in the field.

Population control of small sucking insects has been challenging, and alternative control methods are constantly being sought. Visual traps have long been used to monitor and control pests. Colored sticky cards are widely used for diurnal pests, but their effects are influenced by environmental light conditions. Artificial light traps are mostly used for nocturnal pests. Here, we explored and evaluated light-emitting diode (LED) traps for the monitoring and control of small diurnal sucking insects using greenhouse tests targeting the greenhouse whiteflyTrialeurodes vaporariorum. We tested the trapping efficacy of the LED water pan trap, assessed the most attractive LED light and analyzed its efficacy under different weather conditions. The results showed that the LED water pan trap was too inefficient to be useful. Green LEDs were more attractive than yellow LEDs, UV LEDs and green-UV combinations. Regardless of sunny or cloudy conditions, the green LED trap caught more than twice the number of whiteflies than the yellow sticky card alone under summer shading conditions. Our study suggests that LED traps have a significant field application value in whitefly mass trapping and may also be efficient for other diurnal insects. The design of LED traps specific for diurnal insects is discussed.

Periodontitis, a chronic inflammatory disease affecting over one billion people worldwide, is characterized by bacterial infections and hyperactive immune responses. Recent studies have revealed that the formation of neutrophil extracellular traps (NETs) contributes significantly to periodontal tissue destruction, and NETs degradation plays a critical role in periodontitis treatment. Current treatments, including mechanical debridement and systemic antibiotics, face limitations such as antibiotic resistance and insufficient local efficacy. To integrate antibacterial and NETs-elimination strategies, the authors propose a novel therapeutic approach using bifunctional core-shell microneedles (MNs) that deliver two types of nanozymes: a peroxidase (POD)-like palladium (Pd) nanozyme in the inner core layer and a DNase-like dendritic mesoporous silica nanoparticles (DMSN)-cerium (Ce) nanozyme in the outer layer. The Pd/Ce MNs are designed to facilitate the rapid release of Pd for bacterial eradication and the sustained release of DMSN-Ce for NETs degradation. This study details the synthesis and characterization of two nanozymes and core-shell structured MNs, followed by evaluations of their catalytic activities, in vitro biocompatibility, antibacterial efficacy and NETs-cleavage ability. In vivo testing using a rat model of periodontitis demonstrates significant improvements in bacterial clearance, inflammation reduction, and alveolar bone preservation. In conclusion, these findings suggest that Pd/Ce MNs with superior antibacterial and NETs-hydrolyzing properties represent a promising therapeutic strategy for the management of periodontitis.

Grapholita molesta (Busck) (the oriental fruit moth; OFM) and Conogethes punctiferalis (Guenée) are both fruit and stem borers with overlapping habitats, occurrences, and outbreak cycles. These two species are in different families and they have completely different sex pheromone components. Here, the effects of the sex pheromone components of C. punctiferalis , ( E )-10-hexadecenal ( E 10-16:Ald) and ( Z )-10-hexadecenal ( Z 10-16:Ald) and their mixture, were evaluated on the sexual communication of OFM by examining electrophysiological (EAG) and behavioral responses. We found that a considerably large amount of E 10-16:Ald or Z 10-16:Ald and a tiny amount of OFM pheromone elicited comparable EAG responses in OFM males, indicating the low antennal olfactory sensitivity of OFM males to the heterospecific pheromone compounds. In two different peach orchard parcels, captures of OFM by their pheromone lures baited in delta traps were increased by at least 1.5 times when OFM pheromone lures were combined with lures that contained 1000 μg of either E 10-16:Ald, Z 10-16:Ald or their mixture. In two other pear orchard parcels, both E 10-16:Ald and Z 10-16:Ald increased captures of OFM in Unitraps in a dose-dependent manner with more than a four-fold increase. Therefore, the enhanced attractiveness of OFM lures by the two interspecific pheromones suggests their potential application to improve mass trapping, population monitoring and mating disruption of OFM.

The major obstacles delaying the commercialization of thin film solar cells based on hybrid organic halide perovskite are the expensive materials, instability of the devices and the complicated multi-step fabrication process. To solve these challenges, we present a simple and high material utilization strategy which employing the polyethyleneimine (PEI) interface abduction to in-situ fabricate perovskite layer and hole transporting layer (HTL) from MAPbI 3 and Spiro-OMeTAD (SPI) mixed precursors in single step. Analyzation find that the in-situ phase separation is induced by the PEI abduction. The existence of PEI blocks SPI form Ti–O bond with bottom TiO 2 surface and converting the interaction between SPI and bottom interface to Van der Waals interaction . Employing this fabrication technique for PSCs, remarkably improves materials utilization of perovskite and SPI, as well as exhibiting superior stability of about 95% initial efficiency even after 68 days of storage in ambient condition without encapsulation. We believe that our strategy will pave a new way for simple, economical and stable PSCs preparation, and provide an inspiration to simplify fabrication process for organic-inorganic electronic devices.

Introduction Sepsis-induced cardiomyopathy (SIC) is a rapidly advancing condition associated with a poor prognosis due to the lack of effective treatments. Neutrophil extracellular traps (NETs), however, act as a double-edged sword in the innate immune response during sepsis. N-formyl methionine (fMet) has been documented to induce NETs in inflammatory conditions, yet its clinical significance and biological function in SIC remain unclear. In this study, we investigated whether fMet induces excessive NETs, thereby promoting SIC. Methods and results Clinically, serum fMet levels were quantified using ELISA, revealing a significant elevation in patients with SIC compared to non-sepsis patients and healthy controls. The fMet levels were positively correlated with the NETs-related markers myeloperoxidase (MPO) and double-stranded DNA (dsDNA) in patients with SIC. Treatment with lipopolysaccharide and fMet increased NET formation in human neutrophils and upregulated the expression of formyl peptide receptor 1 (FPR1) and hypoxia-inducible factor 1-alpha (HIF-1α). Furthermore, bone marrow-derived neutrophils (BMDNs) were isolated from global FPR1 knockout mice, and FPR1 deficiency in BMDNs was found to suppress NETosis. The cecal ligation and puncture (CLP) model was employed to induce SIC in mice and we found knockout of FPR1 improved outcomes in CLP mice, as evidenced by survival benefit, increased cardiac function, attenuated cytokine storm, reduced neutrophil infiltration, improved mitochondrial function and suppressed NETosis, compared with those of wild-type (WT) mice. In addition, treatment with FPR1 inhibitor HCH6–1 improved cardiac outcome and inhibits NETosis in CLP mice. Conclusion These data reveal the role of fMet-mediated FPR1/HIF-1α activation in promoting SIC through the NETosis, indicating novel therapeutic strategy for SIC.
