Summary: Circadian clocks, controlled by the period gene, regulate many behavioral and physiological rhythms in the moth Plutella xylostella. Loss of the period gene disrupts locomotor activity rhythms, affects pupal eclosion, mating, egg-laying, and egg hatching, and alters molecular and transcription rhythms in the heads of the moths.

Summary: The study identified the key role of PxPSI in male sex determination in Plutella xylostella, causing male-specific defects and changes in sex-biased gene expression in mutants, leading to male sterility. This suggests PxPSI as a potential molecular target for genetic-based pest management in lepidopteran pests.

Summary: This study identified 39 putative OBP genes from the diamondback moth genome and transcriptome sequences, and investigated their expression patterns across different developmental stages, sexes, and tissues. The results showed that most OBPs were highly expressed in adult antennae, with certain OBPs being regulated by mating activities and host plant feeding.

Summary: This study examines the impact of Bt-based bioinsecticides on the predation of Euborellia annulipes on Plutella xylostella. The results show that uninfected larvae are consumed less than Bt-infected larvae in a no-choice condition, and uninfected larvae are preferred over Dipel-infected larvae in a free-choice condition. Overall, the preference of the predator is towards uninfected larvae. These findings provide important insights into the interactions between earwigs and Bt.

Summary: Insect biogenic amines mediate behavioral and physiological processes through binding to biogenic amine receptors (BARs) in the G-protein-coupled receptor superfamily. This study cloned and characterized 17 genes encoding putative biogenic amine receptor proteins from the global pest Plutella xylostella, providing insights into potential target sites for pest control. The molecular properties, expression profiles, and pharmacological characterization of these BARs, including dopamine receptor PxDOP2, were investigated, offering valuable information and resources.

Summary: Body pigmentation is a crucial adaptation for insects, with some genes involved in melanization being used in genetic studies. A study on Plutella xylostella identified a homologue of the Bombyx mori melanization-inhibiting gene ebony, and utilized CRISPR/Cas9 to generate a knockout strain, revealing darker pigmentation. Fitness costs of Pxebony deficiency were assessed, with reduced embryo hatchability and larval survival observed. This study provides a potential target for CRISPR-based genetics-control systems in economically important pest lepidopterans.

Summary: The diamondback moth (DBM) has adapted to the chemical defenses of Brassicaceae plants, but its role in the DBM's adaptation to plant defense compounds is unknown. In this study, the secondary metabolites of radish seedlings were identified and found to reduce the growth of DBM larvae lacking gut bacteria. However, the re-introduction of Enterobacter dominated gut microbiota counteracted this effect. The bacterium Enterobacter not only degrades the flavonoid kaempferol, but also colonizes the gut epithelium, forming a protective biofilm.

Summary: This research identified insecticides that are least toxic to the parasitoid Diadegma insulare, an important natural enemy of the diamondback moth, to help farmers choose products that have a reduced impact on the natural field populations of D. insulare while effectively controlling the pest. The study also emphasized the need for better integration of natural control and chemical control in managing the main pest of cruciferous crops worldwide, Plutella xylostella. Some insecticide toxicity and residual activity should be considered within integrated pest management programs to conserve the role of D. insulare in field populations.

Summary: This review discusses the pest Bemisia tabaci and the advancements in strategies for its control. Genetic engineering techniques, such as transgenics and RNA interference, have shown promise but face challenges due to concerns about GMOs in food crops. New technologies, like manipulation of microbiota and CRISPR-based genome editing, have shown promising results and could play a key role in controlling agricultural pests including whitefly.

Summary: CRISPR/Cas9-based homing gene drives are a potential new approach to mosquito control. In this study, researchers successfully generated transgenic Ae. aegypti lines expressing Cas9, which significantly biased the inheritance of an sgRNA-expressing element. The sds3G1-Cas9 isolate showed the highest average inheritance, indicating its potential for driving the spread of the targeted element more efficiently.

Summary: Karst landscapes are unique among terrestrial ecosystems due to their poor soil fertility, water retention, and water holding capacity. The complex microhabitats in karst areas have facilitated species differentiation within the region. This study focused on the adaptation strategies of Ampelocalamus luodianensis, a bamboo species specialized in karst habitats. The findings revealed that biomass distribution varied in different years and microhabitats, and was influenced by environmental factors such as soil composition and temperature.

Summary: To address the issue of lithium (Li) plating on graphite anodes during fast charging, Li plating regulation and morphology control are proposed. A Li plating-reversible graphite anode is achieved through a localized high-concentration electrolyte (LHCE), resulting in high reversibility and stability. The stable LiF-rich solid electrolyte interphase (SEI) enables a higher average Coulombic efficiency (99.9%) and reversibility of Li plating (99.95%). A self-made LiNi0.5Mn0.3Co0.2O2 | graphite pouch cell exhibits a competitive capacity retention of 84.4% even at high current (7.2 A) after 150 cycles, demonstrating the potential for high-performance fast-charging batteries.

Summary: Insect hormones, particularly juvenile hormone (JH), play a crucial role in regulating insect life-history traits and their response to Bacillus thuringiensis (Bt). This study identified and characterized a JH esterase gene (PxJHE) from Plutella xylostella and demonstrated its differential expression in Bt Cry1Ac resistant and susceptible strains. The study also found that miR-108 or miR-234 can target and regulate PxJHE expression, subsequently affecting the tolerance of P. xylostella larvae to Cry1Ac protoxin.

Summary: A label-free difunctional electrochemiluminescence (ECL) sensor was developed for ultrasensitive detection of mercury ions (Hg2+) and silver ions (Ag+) using Ru(bpy)32+-functionalized metal-organic frameworks (Ru-MOFs) and the strand-displacement-amplification (SDA) reaction. The sensor achieved enhanced detection sensitivity by combining SDA with Ru-MOFs, which also provided a stable carrier for DNA during sensor construction. The sensor demonstrated low detection limits for Hg2+ and Ag+ ions and was successfully applied for their determination in seawater, making it an ideal platform for simultaneous detection of trace heavy metal ions.

Summary: Waveguide tapers are essential in silicon photonics for maximizing the coupling efficiency, but they require large footprints. A concept of taper-free waveguides is proposed, enabled by photonic topological phases, allowing efficient coupling without tapers. The experiment on an all-silicon on-chip terahertz wave platform confirms the efficacy of this concept, demonstrating its robustness against sharp corners and potential barriers. This work provides a promising solution for future compact optical/THz photonic integrated circuits.

Summary: Gene drive is a genetic engineering technology that allows specific alleles to spread through a population. CRISPR toxin-antidote gene drives are the most promising type, which disrupts essential wild-type genes and increases the frequency of the drive. These drives rely on an effective rescue element, either at the same site or a distant site from the target gene.

Summary: Inert digestibility index markers like titanium dioxide are commonly used in poultry feeding trials. However, the use of titanium dioxide in cell biology for enrichment of inositol phosphates suggests that its use as an inert marker may not be as inert as assumed. Our experiment showed no significant difference in the effect of phytase inclusion in the presence or absence of titanium dioxide, indicating that its inclusion in feed does not interfere with the recovery of inositol phosphates from digesta samples.
