The study was carried out in the agricultural landscape (mosaic of an urban environment, gardens, grassland, fields, small forests and semi-natural non-forest habitats) in central Europe (southeast Czechia) in 2021. A light trap was used for trapping (207 nights). A total of 485 moth species and 5 170 individuals were captured. Eurytopic species dominated the area, 72% of species and 89% of individuals. Fifty-nine species are considered pests (12%), representing 25% of individuals. The seasonal dynamics of selected harmful species were evaluated and discussed. Species of semi-natural dry and wet habitats were represented by 14%, i.e. a proportion comparable to pests, but with only 4% of individuals. The numbers of species and individuals recorded and the Shannon-Wiener diversity and evenness indices are lower than at natural sites. Yet, overall biodiversity is relatively high, including the presence of some rare, ecologically, or zoogeographically remarkable species.Â

Glyoxal oxidase (GLOX, EC 1.2.3.15) is a class of hydrogen peroxide synthases involved in lignin degradation. Several GLOX genes of biotrophic and necrotrophic phytopathogenic fungi have been confirmed to contribute to fungal growth, development, and pathogenicity. However, the composition, sequence characteristics and functions of genes in the GLOX family of hemi-biotrophic phytopathogenic fungi remain poorly understood. This study identified a GLOX-encoding gene CsGLOX in the hemi-biotrophic phytopathogenic fungus Colletotrichum siamense by bioinformatics analysis and PCR cloning. The encoded protein contains a signal peptide and five cell wall stress-responsive component (WSC) domains at the N terminus, followed by a catalytic structural domain (AA5_1). CsGLOX-deficient mutants were constructed by homologous replacement, which significantly increased the formation of conidia and reduced the pathogenicity and the high-osmotic stress tolerance of the fungus. However, the deletions did not influence fungal filamentous growth. This study proposes that the CsGLOX gene is involved in pathogen conidial formation, pathogenicity, and osmotic stress response, which deepens our understanding of the pathogenic mechanism of hemi-biotrophic phytopathogenic fungus C. siamense.

Symptomatic samples were taken from five districts in Yogyakarta and Central Java provinces of Indonesia to survey the genetic diversity of Begomovirus, α and β satellites. A total of 14 samples were tested positive by PCR for tomato leaf curl New Delhi virus (ToLCNDV), pepper yellow leaf curl Indonesia virus (PepYLCIV), mungbean yellow mosaic India virus (MYMIV), and ageratum yellow vein China virus (AYVCNV) infections. Besides that, ageratum yellow vein alphasatellite (AYVA) was identified for the first time in Indonesia, and tomato leaf curl Java betasatellite (ToLCJaB) were detected for the first time in different hosts. Partial genome sequences of begomoviruses and complete sequences of the α and β satellites were recovered and registered in NCBI GenBank (OP846592-OP846615). Phylogenetic study showed that AYVA and ToLCJaB each had two separate lineages. Polymorphism and diversity analyses confirmed other reports that βC1 coding region of ToLCJaB genome is highly conserved. Comparison of phylogroups 1 and 2 of ToLCJaB produced a high FST value, indicated genetic isolation between them. This report could be a basis for future works on the less studied genetic variation of α and β satellites in Indonesia and other countries.

Chemical fungicides can cause drug resistance of plant pathogenic fungi, environmental pollution, and potential threats to humans and animals. Therefore, developing low-toxicity, high-efficient and environment-friendly biological control products is critical for green prevention, controlling plant fungal diseases, and maintaining ecological balance. Biocontrol research mainly includes the following aspects: antagonistic microorganisms, fungicidal proteins, RNA interference techniques and botanical fungicides. Significantly, natural products extracted from medicinal plants are valuable repertoire for inhibiting plant fungal diseases. This review systematically reviewed the research advances of using natural products from medicinal plants to inhibit plant pathogenic fungi, including the types of natural products, extraction methods, and antifungal mechanisms. The further prospects for the study and application, which provide the reference for botanical fungicide development and practical application in preventing and controlling plant fungal disease, were also discussed.

Plant-based biopesticides such as extracts of neem and eucalyptus are gaining increasing attention as potential alternatives to synthetic pesticides due to their reduced toxicity to non-target species and the environment. The present study aimed to evaluate the efficacy of ethanolic and aqueous extracts of neem (Azadirachta indica A. Juss.) and eucalyptus (Eucalyptus citriodora Hook.) as biopesticides against the brinjal fruit and shoot borer (BFSB) (Leucinodes orbonalis), a major pest of brinjal (eggplant) crop. Experiments were conducted to determine the lethal concentration of both neem and eucalyptus extracts against BFSB larvae. The biopesticides were applied to brinjal fruit and their efficacy was evaluated by monitoring the mortality of BFSB larvae and pupae. The results showed that both neem and eucalyptus extracts were effective in controlling BFSB larvae, with the neem extract being slightly more toxic than the eucalyptus extract. A 5% concentration of ethanolic and aqueous extracts of neem caused 82% and 64% mortality of BFSB 3rd instar larvae, while the same concentration of eucalyptus extracts caused 73% mortality with 60% mortality, respectively. BFSB 5th instar larvae showed a decreased mortality as compared to 3rd instars. It concludes that the use of aqueous and ethanolic extracts of neem and eucalyptus could help to reduce the use of synthetic pesticides to control brinjal fruit and shoot borer. Further studies are needed to assess the long-term effectiveness and sustainability of these biopesticides in controlling BFSB and protecting brinjal crops.
