Drosophila suzukii is an invasive pest causing high losses of agricultural crops. Conventional treatment strategies are considered problematic for their high risk of inducing resistance and environmental harm. Photodynamic Inactivation (PDI) is based on the photosensitizer-mediated and light-dependent generation of reactive oxygen species. Natural and food-grade photosensitizers, such as the food additive sodium magnesium chlorophyllin (Chl, E140), have been proven effective against microbial pathogens and several agricultural pests. The aim of this study is to assess whether the principle of Chl-based PDI of D. suzukii could be transferred from laboratory towards practical conditions.

铃木果蝇是一种入侵害虫，给农作物造成严重损失。传统的治疗策略被认为存在问题，因为它们极有可能诱发抗药性并对环境造成危害。光动力灭活（PDI）是基于光敏剂介导的、依赖光产生的活性氧。天然和食品级光敏剂（如食品添加剂叶绿素镁钠（Chl, E140））已被证明对微生物病原体和几种农业害虫有效。本研究的目的是评估基于 Chl 的苏云金蝽 PDI 原理是否可以从实验室转移到实际条件下。

The global agricultural sector faces immense challenges in ensuring food security for a growing population while safeguarding environmental and human health. The discovery of new products and solutions for the sustainable crop protection of the future is an imperative necessity and a matter of great urgency. With the purpose to showcase the most recent innovations and developments in crop protection the 15th IUPAC International Congress of Crop Protection Chemistry was held in 2023. This Special Issue comprises 26 articles and provides information on the latest innovations in crop protection research that were presented at this congress or resulted from accompanying discussions. © 2025 Society of Chemical Industry.

A promising strategy to optimize biological control of insect pests is selecting crop varieties with indirect defense traits. Indirect plant defenses recruit natural enemies to kill pests and include chemical attractants like herbivore-induced plant volatiles. In prior laboratory assays, we found sorghum (Sorghum bicolor L.) cultivar ATx3409/RTx436 infested with sorghum aphid (Melanaphis sorghi Theobald) was attractive to natural enemies and emitted more chemical attractants than two other cultivars. In this field study, we manually infested 9-week-old sorghum plants with aphids and quantified differences in natural enemy and aphid densities among cultivars throughout the growing season. We also used field cages to control access of natural enemies to plants and estimate their effects on aphid suppression.

选择具有间接防御特性的作物品种，是优化害虫生物防治的一种可行策略。植物的间接防御功能可以招引天敌来杀死害虫，还包括化学引诱剂，如食草动物诱发的植物挥发物。在之前的实验室试验中，我们发现高粱（Sorghum bicolor L.）栽培品种 ATx3409/RTx436 在遭受高粱蚜（Melanaphis sorghi Theobald）侵染时对天敌具有吸引力，并且比其他两个栽培品种释放出更多的化学引诱剂。在这项田间研究中，我们用人工方法在 9 周大的高粱植株上施放蚜虫，并量化了不同栽培品种在整个生长季中天敌和蚜虫密度的差异。我们还使用田间笼子来控制天敌与植株的接触，并估计天敌对抑制蚜虫的影响。

Weeds are a menace in agriculture causing crop yield reductions to the tune of 40–50%. To overcome the problems of weeds, herbicides have been used excessively to the extent that they have caused resistance in weeds, in addition to the environmental hazards. Nano-herbicides are intended to exploit botanicals to develop novel bio-nano-herbicide formulations. Bio-nano herbicide was developed using Eucalyptus citriodora essential oil combined high-energy approaches such as ultra-sonication and high-pressure homogenization. The formulation has hydrodynamic and physical sizes of 95.5 and 32.3–57.7 nm, respectively. The product was tested for their pre-emergence and post-emergence herbicidal activity against Echinochloa crus-galli.

Casuarina wilt is a destructive soil-borne disease caused by Ralstonia solanacearum species complex (RSSC). Recent large-scale outbreaks of Casuarina wilt in the coastal regions of Guangdong Province, China, suggest that the originally resistant Casuarina clones become susceptible to RSSC infection. This study aimed to investigate the microbial diversity of environmental microorganisms and its potential in biocontrol of this devastating disease.

BACKGROUNDRNA interference (RNAi) is a promising strategy for aphid control; however, its practical application has been limited by low efficiency in aphids. To address this, we combined transcriptomic analysis with an ‘RNAi of RNAi’ approach to identify genes associated with RNAi efficiency in green peach aphid Myzus persicae.RESULTSUsing the artificial diet‐mediated dsRNA delivery method, we observed that ingestion of both dsMpHunchback and dsfusion (a dsRNA targeting three genes) induced RNAi effects. These included significant gene silencing and reduced nymph production at 24, 36, and 48 h post‐feeding compared to dsGFP. Expression profiling of core RNAi machinery revealed that samples from 36 and 48 h post‐feeding were critical for RNAi efficiency, prompting their selection for transcriptome sequencing. Weighted gene co‐expression network analysis (WGCNA) and analysis of Differentially Expressed Genes (DEGs) were employed to elucidate the RNA‐seq data. Subsequent validation through RNAi of RNAi assay demonstrated functional roles for genes encoding basic region leucine zipper (gene11325), cathepsin B‐like (gene12476), glucosidase KIAA1161‐like (gene6489), and piggyBac transposable element‐derived protein 3‐like (gene7736). Notably, gene11325 and gene6489 were associated with RNAi efficiency, whereas gene12476 and gene7736 appeared to exert compensatory effects that counteracted the RNAi effects induced by dsMpHunchback and dsfusion.CONCLUSIONThese findings highlight the functional diversity of genes influencing RNAi efficiency in green peach aphid, enhancing our understanding of RNAi mechanisms and establishing a foundation for optimizing RNAi‐based aphid control strategies. © 2025 Society of Chemical Industry.

Both insertion mutation and low expression of nicotinic acetylcholine receptor Nlα4 subunit are associated with sulfoxaflor resistance in Nilaparvata lugens

Sulfoximine insecticide sulfoxaflor acts on insect nicotinic acetylcholine receptors (nAChRs). Metabolic resistance arising from increased activity of detoxification enzymes has been extensively documented in insect populations. Prior research by the present authors demonstrated the involvement of cytochrome P450 monooxygenases in mediating metabolic resistance to sulfoxaflor in Nilaparvata lugens. Nevertheless, investigations into the target-site resistance mechanisms of insects to sulfoxaflor remain limited.

Plants emit volatile organic compounds (VOCs), which serve as critical cues for herbivorous insects to locate hosts for feeding and oviposition. Understanding how adults identify host plants is essential to develop pest management strategies, particularly for hemiedaphic insects like click beetles, the larvae of which are significant soil-dwelling pests. To investigate click beetle attraction towards plant VOCs and their relevance for oviposition, we tested the attractiveness of constitutive VOCs (emitted by intact plants) and damage-induced VOCs (released by chopped plants) from 11 plant species to male and female Agriotes sputator beetles.
