In fire-prone habitats, bees depend on plants for gathering resources, and on the availability of nesting resources. Consequently, bee communities are expected to vary spatially and temporally due to changes in plant dynamics provoked by fire. Bee’s resilience to fire is highly influenced by their life history traits and behavioral strategies. Bees may employ a variety of strategies to survive fire including fleeing, sheltering, and entering dormancy during active fire seasons. Recovery of burned patches through recolonization is a key strategy in constructing resilient communities at the landscape level. While polylectic species may have a significant advantage over more specialized foragers in dispersion and recolonization in post-burned habitats, belowground nesters have an advantage over cavity nesters through fires and during early stages. In the context of climate crisis, fire regimes are expected to intensify, potentially threatening bee diversity by altering resource availability and habitat structure. Future studies should incorporate approaches that consider temporal and spatial scales, fire history, bee functional traits, and other aspects, such as voltinism and developmental stages to better predict both species- and community-level responses to fire.

In northeastern Brazil, populations of Montella sp. (Coleoptera: Curculionidae) have emerged as a significant pest of vanilla crops, with both larvae and adults causing damage. Notably, adults are frequently observed on the flowers, suggesting a potential role of floral volatile organic compounds (VOCs) in host localization. To investigate this, we analysed the floral VOC profile of V. planifolia using dynamic headspace collection followed by gas chromatography–mass spectrometry (GC-MS). Six compounds were identified: β-myrcene, (R)-limonene, (Z)-β-ocimene, eucalyptol, (E)-β-ocimene, and β-caryophyllene, with (E)-β-ocimene being the predominant component of the natural floral bouquet. In Y-tube olfactometer assays, Montella sp. adults were significantly attracted to fresh flowers, floral VOC extracts, and a β-ocimene isomer mixture (Z/E = 1:3), the latter eliciting responses comparable to the full floral extract. These findings indicate that β-ocimene contributes to the attraction of Montella sp. and may be involved in host location, with the (E)-isomer representing the predominant form in the natural floral blend.

Previous research on this topic has been limited and has mostly focused on comparisons among functional groups within narrow taxonomic groups, such as bees. To investigate this issue more broadly, we assessed how 11 groups of insect pollinators spanning four major orders in a Japanese satoyama landscape, classified by both taxonomy and putative behavioral differences, varied in the heterospecificity of pollen on their bodies. Despite being collected from flowers of the same Ligustrum trees in close proximity, the body pollen profiles of these insects significantly differed—both among and within the 11 groups—in terms of the proportion of heterospecific (non-Ligustrum) pollen, the composition of pollen species, and the diversity of pollen species. Notably, marked variations were found within bees, flies, and beetles, as well as between males and females of the same bumble-bee species. We discuss the implications of these findings for the ecological relevance of pollinator groupings based on taxonomy and morphology in terms of their HPT potential, and how variation among and within groups may shape our understanding of their diverse effects on plants.</div>","PeriodicalId":8409,"journal":{"name":"Arthropod-Plant Interactions","volume":"20 3","pages":""},"PeriodicalIF":1.3,"publicationDate":"2026-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148009492","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}

Hancornia speciosa Gomes (Apocynaceae), popularly known as mangabeira, is native to Brazil and widely distributed in savannas, open sandy landscapes, and coastal restinga vegetation formations. Its edible fruits generate income for thousands of families. We recorded attacks by Asphondylia hancorniae, a specialist endoparasitic gall midge, on immature H. speciosa fruits on trees in the Chapada Diamantina mountains and in the coastal zone, Northeastern Brazil, for 24 months. We also investigated the influence of environmental variables on this process. Asphondylia hancorniae attacks cause the withering of immature fruits before seed formation and dispersal. We suggest the use of the Fournier Intensity Index as a quantitative tool to assess the intensity of seed predation and plant disease occurrence in a standardized and comparable manner. Predation intensity reached 47.22% in coastal zone and 35.65% in the inland Chapada Diamantina mountains populations and showed positive correlations with temperature and photoperiod. This approach is especially important for conservation strategies aiming to understand the impact of fruit losses in H. speciosa caused by the gall midge A. hancorniae and how contrasting climatic factors modulate those plant-insect interactions. The damage caused by A. hancorniae on fruits allowed secondary attacks by Hypothenemus obscurus, an association not previously reported as involving a Cecidomyiidae fly and a Scolytinae bark beetle.

The analysis identified 2,588 metabolites in fourth-instar larvae (n = 15), 2,369 in larval feces (n = 15), 636 in adult females (n = 15), 929 in female feces (n = 15), and 3,161 in Parthenium leaves (n = 15 plants). Enrichment analysis based on chemical structure revealed distinct differences in chemical classes across the four groups: fourth instar larvae, larval feces, adult females, and female feces. A comparative analysis of metabolic pathways across all groups identified 11 pathways common to all, five shared only by larvae and adult females, seven exclusive to larvae, and one unique to adult females. Metabolomic profiles of larvae, adult females, and their feces contained a range of compounds, including terpenoids, flavonoids, amino acids, pseudo-guaianolides, carbohydrates, and phenolic acids. Among these, seven potential phytotoxic compounds—caffeic acid, vanillic acid, ferulic acid, chlorogenic acid, quinic acid, anisic acid, and parthenin—were also detected in the host plant P. hysterophorus. These findings highlight significant differences in the metabolic profiles of Z. bicolorata and its host plant, providing new insights into the insect's detoxification mechanisms. This study enhances our understanding of the complex biochemical interactions between Z. bicolorata and Parthenium, contributing valuable knowledge for biocontrol applications.\u0000 </div>","PeriodicalId":8409,"journal":{"name":"Arthropod-Plant Interactions","volume":"20 3","pages":""},"PeriodicalIF":1.3,"publicationDate":"2026-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147754440","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}
