TL;DR: Insecticide resistance has been and continues to be a significant problem for invertebrate pest control as discussed by the authors, and effective insecticide resistance management (IRM) is critical to maintain the efficacy of current and future insecticides.

TL;DR: It is suggested that the QNLC is a promising antioxidant for drug delivery to be used as a therapeutic and prophylactic agent for PQ poisoning.

TL;DR: The results suggest that strain B21 and its bioactive compounds have the potential to be developed into a biopesticide for the biocontrol of rice blast.

TL;DR: The results show the hormetic effects of thiamethoxam on F1 individuals, which might be due to the intermittent changes in expression of genes involved in fertility, growth and insecticide detoxification in A. gossypii.

TL;DR: The results showed that among eight insecticides, emamectin benzoate, spinetoram, chlorantraniliprole, chlorfenapyr, and lufenuron showed higher toxicity to this pest, while lambda-cyhalothrin and azadirachtin exhibited lower toxicity.

TL;DR: The article explores the potential in enhancing Si-mediated plant resistance against various economically important diseases and insect pests, further shedding light upon future issues regarding the role of Si in defense against pathogens and Insect pests.

TL;DR: Results highlighted that polymer chitosan nanoparticle encapsulated with essential oil is a promising novel design that could be promoted in stored food pest management schedule for T. castaneum and S. oryzae.

TL;DR: The goal of this review is to critically summarise the current knowledge and the gaps of the CYP-based metabolic insecticide resistance in Anopheles and Aedes mosquito vectors.

TL;DR: RNA interference-mediated knockdown of CYP6CY14, CYP 6DC1, and CYP5CZ1 genes significantly increased the sensitivity of Ace-R strain to acetamiprid, which could be useful to understand the molecular basis of acetAMiprid resistance mechanism in A. gossypii.

TL;DR: Overall results of nanoformulation indicated that these novel design systems could be promoted in integrated pest management schedule for T. castaneum and S. oryzae.

TL;DR: Bacillomycin D showed more potent activity against C. gloeosporioides (Penz.) than two common fungicides prochloraz and mancozeb and reveals its high potential as a biopesticide to control phytopathogens.

TL;DR: The first report of the control effect of LGO, CO, and their nanocapsule in MSNPs against the take- all disease of wheat showed that the EOs-MSNPs can be a safe product for the efficient control of take-all disease in wheat crop.

TL;DR: This study provides a foundation for exploring the olfactory mechanism of A. lepigone and identified two potential target genes for the development of highly effective insecticides in the future.

TL;DR: The results strongly suggest that due to its strong endosomal escaping ability, CQD was the most efficient carrier for inducing systemic RNAi, and thereby causing effective gene silencing and mortality in SSB.

TL;DR: This study indicates that C. sinensis essential oil and its constituents have potential to be developed into botanical pesticides.

TL;DR: Confocal laser scanning microscopy images of fungi treated with cinnamon bark and lemongrass essential oils, trans-cinnamaldehyde, neral, and geranial revealed the reactive oxygen species (ROS) generation and cell membrane disruption.

TL;DR: The results of this study suggests that B. methylotrophicus DR-08 can be utilized as a biocontrol agent for various bacterial plant diseases including tomato bacterial wilt.

TL;DR: This is the first study to report that the novel Asp-2078-Glu mutation confers resistance to several ACCase inhibitors, and a number of herbicides remain effective in controlling this MHR E. crus-galli population.

TL;DR: This work provides a valuable clue for further study of pyrethroid resistance mechanisms in S. litura and shows that multiple differentially expressed genes were enriched in metabolism-related GO terms and KEGG pathways.

TL;DR: The advances that have been made through the application of genome modification technology in insecticide resistance research are presented and an experimental framework that may circumvent current limitations while retaining the genetic versatility and robustness that Drosophila has to offer is discussed.

TL;DR: Results demonstrated the overexpression of CYP6CY14, CYP 6CY22 and CyP6UN1 contributed to dinotefuran resistance in A. gossypii.

TL;DR: It is demonstrated that sensitivity of CPB to sprayable RNAi slightly varies between strains but also shows that foliar RNAi as a control method works against all tested CPB populations collected across a broad geographic range in Europe.

TL;DR: It is suggested that pinocembroside suppressed postharvest blue mold by direct inhibition of P. italicum mycelial growth via membrane-targeting mechanism, thus providing a novel mode of action against traditional fungicides for controlling blue mold of citrus fruit.

TL;DR: Cloned the antennal esterase SexiCXE11 cDNA full-length sequences from the male antennae of a notorious crop pest, Spodoptera exigua, and its encoded 538 amino acids are cloned to facilitate a better understanding of moth ODE differentiation and suggest strategies for the development of new pest behavior inhibitors.

TL;DR: The importance of Bacillus-derived proteins/peptides in the inhibition of P. nicotianae through irreversible damage to its cell wall and membrane is demonstrated and the effectiveness of PGPR strain B. velezensis Ba168 for biocontrol of the soil-borne disease caused by TBS is demonstrated.

TL;DR: The antibacterial mode of action of trans-cinnamaldehyde and salicylaldehyde is ROS generation by the Fenton reaction caused by the down-regulation of an ATP synthesis-related gene cluster, corrupted iron ion homeostasis, and a corrupted ROS defense mechanism.

TL;DR: The results showed that the Nrf2/ARE signaling pathway has a protective effect in cypermethrin-induced apoptosis of the cortical neurons, however, this protective effect is very limited and is dependent on the exposure dose and exposure period of cy permethrin.

TL;DR: The presence of high resistance levels (up to >640-fold) against ketoenol insecticides in both Spanish and Australian B. tabaci strains of the MED and MEAM1 species, respectively is confirmed and emphasizes the importance of implementing appropriate resistance management strategies to prevent or slow the spread of resistance through global whitefly populations.

TL;DR: The P450 enzyme activity was higher in both selected strains of imidacloprid and acetamipird than that of susceptible strain and CYP6CM1 showed the highest expression level among all the 13 tested genes.

TL;DR: The results show that CYP9A10 might play an important role in xanthotoxin and α-cypermethrin detoxification in S. exigua and RNAi-mediated silencing could provide an effective synergistic agent for pest control or insecticide resistance management.
