Summary: This study observed that Riptortus pedestris can stably colonize Serratia marcescens in the insect midgut without exhibiting insecticidal activity. Additionally, oral infection with S. marcescens does not affect the growth or fitness of the host insect. The findings suggest that orally infected S. marcescens lose their entomopathogenicity due to host-derived degrading factors and suppression of serralysin.

Summary: Symbiotic microorganisms affect the physiology, behavior, and morphology of their host insects. In this study, the symbiotic relationship between the bean bug and Caballeronia bacteria was investigated. The results showed that symbiotic males had larger body size and hind legs, higher feeding efficiency, and enhanced movement and flight capacity compared to apo-symbiotic males. Survivorship did not differ significantly between symbiotic and apo-symbiotic males. However, the titer of Caballeronia symbiont in male bean bugs decreased over time.

Summary: The study identifies Rpfmd as the female determiner gene in the sex determination pathway of R. pedestris, which influences sex differentiation and ovary development. Knockdown of Rpfmd leads to female-specific lethality and male-only offspring, showing potential for genetic control. The findings also enhance understanding of sex determination mechanisms in hemimetabolous insects.

Summary: In this study, 49 putative odorant-binding protein (OBP) genes and 25 chemosensory protein (CSP) genes were identified in the R. pedestris genome. The expression patterns of these genes in the antennae and non-antennal tissues were examined, revealing some genes with sex-biased expression. These findings provide insights into the functions of these genes and potential for developing environmentally friendly insecticides.

Summary: Prokaryotic and eukaryotic microbial symbiotic communities exist across different kingdoms, extending the host genome and aiding adaptation to changing environments. Plants and insects carry a variety of microbes on their surfaces, internally, and even within cells, with the insect gut being a selective environment. Despite their high dependence and frequent interaction, it remains uncertain how much plants and insects exchange and modify each other's microbiomes. This review focuses on herbivores that feed on plants in forest ecosystems, discussing the plant microbiome, overlap with insect microbial communities, and the effects of microbiome exchange on each host's fitness.

Summary: In this study, we investigate the Neumann boundary feedback stabilization for reaction-diffusion equations with matched boundary uncertainties. We propose a prescribed-time boundary control law by estimating the uncertainties within the prescribed time and utilizing backstepping transformation with a time-varying kernel. The Neumann boundary control is proven to be uniformly bounded.

Summary: This paper addresses the adaptive control for a kind of nonlinear system over the event-driven sensors-controller communication network. Two kinds of adaptive control strategies are proposed to overcome the limitations of the existing strategy. The decoupling structure of event-triggered mechanism and adaptive estimators saves communication cost and ensures the asymptotical stability of the system.

Summary: Digestion and absorption of old cuticles during insect molting are essential for new cuticle formation. This study identified 33 trypsin and trypsin-like homologs, 14 metallocarboxypeptidase and 32 aminopeptidase genes in the brown planthopper. Gene silencing experiments showed that certain trypsin-like proteases and a metallocarboxypeptidase were essential for ecdysis in the brown planthopper. These proteins exhibited specific expression patterns and were predominantly located in the exuvial space.

Summary: Direct feeding by Riptortus pedestris is the primary cause of soybean staygreen syndrome, occurring at the early pod stage. Various signal transduction pathways, including photoperiod, hormone, defense response, and photosynthesis, respond to R. pedestris infestation in soybean. Overexpression of floral inducer GmFT2a attenuates staygreen symptoms by mediating soybean defense response and photosynthesis.

Summary: This paper considers the boundary control design of time fractional-order nonlinear reaction-diffusion systems (FNRDSs) in three cases: domain-averaged measurement, collocated boundary point measurement, and anti-collocated boundary point measurement. Boundary controllers are directly designed based on the measurements for domain-averaged measurement and collocated boundary point measurement. For anti-collocated boundary point measurement, an observer is constructed first to overcome the difficulty of using the measurement directly, and then an observer-based boundary controller is designed. Sufficient conditions for the Mittag-Leffler (M-L) stability of the closed-loop system are provided in terms of linear matrix inequalities (LMIs). Numerical simulation results are provided to demonstrate the feasibility and effectiveness of the proposed methods.
