The development of highly efficient and environmentally friendly plant virus inhibitors with novel structures mostly depends on the discovery of new targets. G-quadruplexes are non-classical high-level structures that are formed by guanine-rich nucleic acid sequences, which have significant biological functions. Small molecules that target the G-quadruplexes in the genomes of animal viruses have been shown to inhibit viral proliferation. However, the structure and function of the G-quadruplex in the plant virus genome have rarely been reported. Investigating the function of plant virus G-quadruplexes facilitates the discovery of new targets for screening viral inhibitors.

Outbreaks of the rice leaf folder (Cnaphalocrocis medinalis) poses a significant threat to rice production. Silk-spinning creates an enclosed leaf roll that protects larvae from predators and insecticides, while serving as a feeding site and facilitating host transfer and leaf-folding. Disrupting this behaviour could enhance control strategies. The silk fibroin gene, essential for silk production, remains poorly understood in C. medinalis.

Southern blight, caused by Sclerotium rolfsii, poses a formidable threat to the cultivation of Coptis chinensis, especially affecting both yield and crop quality. Given the environmental harm associated with chemical fungicides, microbial antagonists are emerging as a viable solution for plant disease management. This study aimed to identify bacterial strains with antagonistic properties against southern blight in Coptis chinensis and to evaluate their biocontrol capabilities.

Phthorimaea absoluta (Meyrick) (Lepidoptera: Gelechiidae) poses a significant challenge in tomato cultivation owing to its increasing resistance to various insecticide classes. This study aimed to characterize the resistance of a field-collected P. absoluta population to abamectin, focusing on its genetic aspects and cross-resistance with other chemical groups, and monitoring the frequency of resistance in other populations.

Piezodorus guildinii (Westwood, Hemiptera: Pentatomidae) causes economic losses in soybean crops by diminishing productivity, impacting grain size, oil content, and germination power. RNA interference (RNAi), a conserved gene regulation process initiated by double-stranded RNA (dsRNA), may be used as a safe technique in integrated pest management strategies. Conjugating dsRNA with cationic polymers, which protect dsRNA from degradation has shown to enhance this response. This study aims to assess the impact of dsRNA administration on the viability of P. guildinii and evaluate dsRNA-chitosan nanocomplexes as a pest control strategy.

Weed management is the greatest production challenge for most certified organic farmers, with few herbicides allowed on organic farms. Here, we compared the efficacy and cost of handhoeing (MECH) with a control (no weed management) and four commercially available registered organic herbicides under United States Department of Agriculture organic standards in managing Canada thistle (Cirsium arvense (L.) Scop.) and total vegetative cover in two apple (Malus domestica Borkh.) orchards. The four herbicide treatments had the following active ingredients: capric and caprylic acid (CAP), d-limonene (LIM), acetic and citric acid (ACET), and clove and cinnamon oil (CIN). In separate greenhouse trials, Canada thistle response to CAP (at two concentrations), LIM, glyphosate (GLY), and MECH were also studied.

While natural forests have decreased globally, forest plantations have expanded highlighting the need for studies on plantations’ capacity to sustain biodiversity and provide ecosystem services within agroforestry mosaics. This study examined the breeding habitat preferences of European honey buzzards Pernis apivorus (a native predator of the invasive yellow-legged hornet) and their relationship with reproductive performance in exotic Eucalyptus plantations in southwestern Europe. We expected better reproductive performance in preferred habitats.
