The mechanisms underlying host plant location by spittlebugs—critical for the transmission of associated bacterial pathogens—remain poorly understood, particularly with respect to the potential role of visual cues. Here, we investigated the visual system of <i>P. spumarius</i> through an integrated anatomical, optical, physiological, and behavioural approach to explore the potential role of vision in host-seeking behaviour. Using microscopy, 3D reconstructions, and single-cell recordings, we examined the structure and function of the compound eyes. Optical mapping revealed relatively low spatial resolution, with interommatidial angles of 4°–8° and somewhat smaller angles and finer visual sampling in central and anterior-ventral regions. Intracellular recordings showed that photoreceptors are maximally sensitive to ultraviolet (UV), blue (B), and green (G) light, suggesting the potential for trichromatic colour vision. UV and B-sensitive photoreceptors exhibited high polarization sensitivity (PS), with UV and B photoreceptors maximally sensitive to vertically and horizontally or obliquely polarized light, respectively. The physiological evidence indicating that polarized light is detected primarily by UV and B photoreceptors was complemented by the observation of orthogonally arranged microvilli in anatomical cross-sections of the retina, which might belong to polarization-opponent photoreceptor pairs with orthogonal sensitivity maxima to polarized light. Behavioural tests in a Y-maze demonstrated that starved spittlebugs preferred linearly polarized over a diffuse visual stimulus. This preference disappeared when a yellow filter blocked UV and blue light, implicating the necessity of UV and B photoreceptors for the detection of polarized reflections. Our findings demonstrate that <i>P. spumarius</i> uses visual cues, including polarized light, which may aid in the visual detection of reflections from host plants. Understanding these visual mechanisms provides new insight into the ecology of this key vector species and may inform strategies to disrupt its host-finding behaviour.</p>","PeriodicalId":7977,"journal":{"name":"Annals of Applied Biology","volume":"188 2","pages":"503-519"},"PeriodicalIF":1.8,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aab.70065","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146256416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the farming situations, social acceptability, growers' demand and supply, market requirements, compatibility and profitability in a sugarcane-based system, four modules of integrated farming systems (IFS) were designed and laid out in 1 ha area from 2019–2020 to 2022–2023. These systems were evaluated with autumn (autumn sugarcane-based integrated farming system—ASBIFS) and spring seasons (spring sugarcane-based integrated farming system—SSBIFS). On the basis of compatibility and efficiency of various agri-enterprises with the sugarcane production system, it could be concluded that the inclusion of vegetables, backyard poultry, pisciculture, vermicomposting, apiculture, mushroom, and dairy unit (consisting of two cows) was found compatible and remunerative in increasing system productivity. Autumn sugarcane-based IFS involving all these enterprises recorded the highest mean system productivity (123.6 t/ha/year), gross returns (US$ 4901/ha/year), and net returns (US$ 2509/ha/year). However, spring sugarcane-based IFS integrating all these enterprises recorded the highest system production efficiency (348.8 kg/day), marginal returns (US$ 46 × 10⁻³/day), and relative economic efficiency (146.7%). Thus, autumn-based IFS modules were found more profitable compared to spring sugarcane-based IFS. The higher relative economic efficiency with spring sugarcane-based IFS compared to autumn sugarcane-based IFS indicated that for small and marginal farmers, the spring sugarcane-based IFS was more profitable compared to autumn sugarcane-based IFS. Thus, it could be concluded that the integration of vegetables, including horticultural crops throughout the year, backyard poultry, fisheries, apiculture, mushroom, and dairy unit with sugarcane planting resulted in the highest net returns and B:C ratio and could be adopted by the sugarcane growers for higher profitability and sustainability of the farming system.</p>","PeriodicalId":7977,"journal":{"name":"Annals of Applied Biology","volume":"188 2","pages":"520-535"},"PeriodicalIF":1.8,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147280088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, certain phytoremediator species can mitigate their impact by reducing the availability of Cd in the soil. However, as the exposure to heavy metals significantly affects the plant growth and metabolism of these species, the development of strategies to enhance their tolerance while maintaining their remediation potential is essential. The exogenous application of plant growth regulators (PGRs) can be an effective strategy in this context. However, the biological effects of jasmonates on plant metabolism under Cd stress are not fully understood. This study aims to provide a comprehensive review of phytoremediation and heavy metals tolerance, focusing on the effects of jasmonate application on plants grown in Cd-contaminated environments. It examines the role of jasmonates in Cd tolerance and phytoremediation from a biochemical perspective, considering Cd uptake, malondialdehyde (MDA) levels, the activity of antioxidant enzymes—superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), and ascorbate peroxidase (APX)—as well as glutathione (GSH) content. An exhaustive analysis of all relevant articles published between 2012 and 2024 allowed for classifying the most commonly used methodologies and identifying key physiological responses triggered by jasmonates. The findings confirm that, for most analysed species, the protective effect of jasmonates enhances plant growth and reduces Cd uptake, while improving stress tolerance primarily through the activation of antioxidant enzymes such as superoxide dismutase, catalase, peroxidase, and ascorbate reductase, as well as non-enzymatic antioxidants like glutathione. Although jasmonates promote stress tolerance, as evidenced by improved plant growth, increased antioxidant activity, and a decrease in stress markers, their application should be avoided as a strategy for phytoremediation, since they reduce Cd accumulation in plant tissues.</p>","PeriodicalId":7977,"journal":{"name":"Annals of Applied Biology","volume":"188 2","pages":"390-405"},"PeriodicalIF":1.8,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aab.70062","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146224482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These changes align with our priority of making &lt;i&gt;Annals&lt;/i&gt; even more attractive to the authors and readers, with a wider range of subjects and types of publication, and a more friendly, faster, and easier way to submit the manuscripts. For instance, I can mention the new board structure introduced in July 2025. &lt;i&gt;Annals&lt;/i&gt; has now several SEs divided into the main subject areas covered by the journal. These editors will be handling directly all submissions. This should make the experience better for the authors and ensure a faster editing process.

This study presents the first comprehensive characterization of its phenological development using an extended Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie (BBCH) scale. Fieldwork was conducted from June 2024 to May 2025 in Dimiao, Bohol, Philippines. A species-specific BBCH scale coding was developed, capturing key phenological stages: corm dormancy, leaf emergence, inflorescence development, anthesis, fruiting and senescence. A bimodal life cycle synchronized with the Northeast and Southwest Monsoon systems was observed, with a dormancy phase from October to May and an active reproductive–vegetative phase from April to September, primarily regulated by rainfall and rising temperatures. Observations support a resource allocation trade-off, where corms alternate between reproductive and vegetative investment in response to environmental cues, particularly the onset of the Southwest Monsoon with rising precipitation, consistently high relative humidity and increasing temperatures that signal the shift from dormancy to active growth. Within this framework, the BBCH codes developed encompass dormancy (00), leaf development (10–19), pseudostem elongation (31–39), inflorescence and fruit development (51–59, 60–69, 71–79, 81–89) and senescence with return to dormancy (91–97).
