Solar insecticidal lamps(SIL) can effectively control pests and reduce the use of pesticides. Combining SIL and Internet of Things(IoT) has formed a new type of agricultural IoT,known as SIL-IoT, which can improve the effectiveness of migratory phototropic pest control. However, since the SIL is connected to the Internet, it is vulnerable to various security *** issues can lead to serious consequences, such as tampering with the parameters of SIL, illegally starting and stopping SIL,etc. In this paper, we describe the overall security requirements of SIL-IoT and present an extensive survey of security and privacy solutions for SIL-IoT. We investigate the background and logical architecture of SIL-IoT, discuss SIL-IoT security scenarios, and analyze potential attacks. Starting from the security requirements of SIL-IoT we divide them into six categories, namely privacy, authentication, confidentiality, access control, availability,and integrity. Next, we describe the SIL-IoT privacy and security solutions, as well as the blockchain-based solutions. Based on the current survey, we finally discuss the challenges and future research directions of SIL-IoT.

Inspired by ballpoint pen, an optical biosensor is developed for detection of Salmonellausing a mechanical step rotator with a dropper to greatly simplify operation, a high gradient magnetic field with immune magnetic nanobeads to specifically separate bacteria, and immune gold@platinum nanozymes with a smartphone to sensitively detect bacteria. First, the preloaded bacterial sample is drawn by the dropper to react with the immune magnetic nanobeads through repeated squeezing and releasing of the dropper, and the rotator is successively rotated and the dropper is repeatedly squeezed and released to achieve mixing of the bacteria, magnetic nanobeads and gold@platinum nanozymes, followed by magnetic separation to remove the background. Then, the conjugates are eff ectively washed with skim milk and ultrapure water, and the substrate are rapidly catalyzed into the product. Finally, the blue product is photographed and analyzed using a smartphone to obtain the Salmonella concentration. This biosensor could detect Salmonellaas low as 56 CFU/mL in～25 min.

Improving plant resistance to Verticillium wilt(VW), which causes massive losses in Gossypium hirsutum, is a global challenge. Crop plants need to efficiently allocate their limited energy resources to maintain a balance between growth and defense. However, few transcriptional regulators specifically respond to Verticillium dahliae and the underlying mechanism has not been identified in cotton. In this study, we found that the that expression of most R2R3-MYB members in cotton is significantly changed by V. dahliae infection relative to the other MYB types. One novel R2R3-MYB transcription factor(TF) that specifically responds to V. dahliae, GhMYB3D5, was ***3D5 was not expressed in 15 cotton tissues under normal conditions, but it was dramatically induced by V. dahliae stress. We functionally characterized its positive role and underlying mechanism in VW *** V. dahliae infection, the up-regulated GhMYB3D5 bound to the GhADH1 promoter and activated GhADH1expression. In addition, GhMYB3D5 physically interacted with GhADH1 and further enhanced the transcriptional activation of GhADH1. Consequently, the transcriptional regulatory module GhMYB3D5-GhADH1 then promoted lignin accumulation by improving the transcriptional levels of genes related to lignin biosynthesis(GhPAL, GhC4H,Gh4CL, and GhPOD/GhLAC) in cotton, thereby enhancing cotton VW resistance. Our results demonstrated that the GhMYB3D5 promotes defense-induced lignin accumulation, which can be regarded as an effective way to orchestrate plant immunity and growth.

Mercury（Hg） is among the most concerned contaminants in the world. It has three major chemical forms in the environment, including Hg0, Hg2＋, and methylmercury（MeHg）. Due to their differences in toxicity, mobility, and bioavailability, speciation analysis is critical for understanding Hg cycling and fate in the environment. SnCl2 reduction-atomic fluorescence spectrometry detection is the most commonly used method for analyzing inorganic Hg. However, it should be noted that MeHg may also be reduced by SnCl2, which would result in the overestimation of inorganic Hg. In this study, the reduction of MeHg by SnCl2 in both de-ionized（DI） water and four natural waters was investigated. The results showed that MeHg could be reduced by SnCl2 in DI water whereas this reaction was hard to occur in tested natural waters. By investigating the effects of water chemical characteristics（dissolved organic matter, pH and common anions and cations） on this reaction, SO42- was identified to be the dominant factor prohibiting SnCl2 induced MeHg reduction in natural waters. SO2-4 in natural waters was evidenced to be reduced to S2- by SnCl2 and the generated S2-can complex with MeHg to form MeHg S-which is hard to be reduced by *** of this study indicate that the effect of MeHg reduction by SnCl2 on inorganic Hg analysis is negligible in natural waters; however, at simulated experimental systems without SO42-, SO42- should be added as protecting agents to prevent MeHg reduction when analyzing inorganic Hg if it would not cause any other unwanted effects.
