From India, very few research papers could be reviewed on the pollination ecology of hawkmoths. Herein, we analyzed the interactions of 109 individuals in 39 hawkmoth species to study their role as pollen transporters and potential pollinators. 67 individuals (61.47%), accounting for 29 species (74.35%), are found to be pollen carrier moths (PCM). The hawkmoths transported pollen from 16 plant families, with Ericaceae dominating the pollen composition (33.37% of total pollen grains). The pollen spectra (based on pollen abundance and relative pollen frequency) revealed that 44 PCM (18 species) came from Macroglossinae, followed by 16 PCM (7 species) from Smerinthinae, and 7 PCM (4 species) from Sphinginae. Macroglossinae transported pollen of 14 plant families. The value of selectivity (H2’) is 0.77 for the pollen transportation network and 0.36 for the moth-plant visitation network. We followed the refined method of pollen extraction from proboscides, rather than swabbing body parts, which enabled us to assess pollen carrying capacity in a refined way. Considering the scenario of the declining global pollinators, largely affecting crop production, moths are the least concerned insects for conservation and management. The outcome of the present study will help in strengthening the baseline information for expanding plant-moth interaction network-related studies and considering the least concerned groups of insects in the conservation policies.</p></div>","PeriodicalId":8409,"journal":{"name":"Arthropod-Plant Interactions","volume":"19 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109563","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}

DNA-based diet analyses have been used to study their regulatory effect on soil seedbanks. It is unknown whether specialized granivores digest seed species they are adapted to (‘essential seeds’) faster, and whether this affects food web construction based on molecular data. We hypothesized that specialized granivores digest their essential seed faster than other seeds, and at faster rates than generalist granivores or carnivores. Further, we assumed that generalist granivores digest different seeds equally fast, while carnivorous carabids digest seeds slower than granivores. In feeding experiments, three carabid species—<i>Amara similata</i> (specialized granivore), <i>Harpalus affinis</i> (generalist granivore), and <i>Poecilus cupreus</i> (generalist carnivore)—were fed either a broadly accepted seed or the specialist's essential seed. Gut content samples were collected 0, 6, 12, 24, 48, and 72 h after feeding and screened with plant-primers to trace seed DNA. Time until 50% detection probability in the specialists was shorter for its essential than the broadly accepted seed and shorter than in the generalist granivore, which digested both seed species equally fast. The carnivore was reluctant to feed on the seed species offered, and detection probabilities did not significantly decrease with digestion time. Our findings suggest that the strength of specialized granivores’ feeding interactions and their role in weed seed regulation might be underestimated when assessed with DNA-based diet analysis, due to their more efficient seed digestion.</p></div>","PeriodicalId":8409,"journal":{"name":"Arthropod-Plant Interactions","volume":"19 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11829-024-10122-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109637","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}

Climatic changes, alterations in land utilization, and changes in the salinity levels of irrigation water are the main reasons of rising salinization of soil. Enhanced soil salinity modifies the plant quality, potentially leading to cascading impacts on phytophagous insects. On the other hand, virus infection of host plants can have notable effects on the demographic characteristics of the herbivorous insects including virus vectors. So, in our study we investigated how salinity stress affects the demographic characteristics of <i>Frankliniella occidentalis</i> (WFT) through cherry tomato plant infected with tomato yellow ring virus (TYRV). Despite significant enhancement of adult longevity, oviposition period, and fecundity of WFT on virus-infected plants under no-stress conditions, these parameters were adversely affected by salinity stress, leading to a decline in overall fitness of the WFT. The salinity interfered the development duration of nymphs, adult longevity, and oviposition of WFT. Remarkable differences detected in the intrinsic and finite increase rates as well as the net reproduction rate of WFT under high level of salinity. Salinity had a negative impact on WFT development; nonetheless, population projection forecasted a clear but slower growth trend in WFT population particularly under moderate level of salinity (2.8 dS/m of NaCl), while high level of salinity (4.7 dS/m) led to notable fitness costs in WFT populations. The results imply that WFT may pose a growing threat in both virus-free and virus-infected environments characterized by low to moderate salinity levels, potentially exacerbating the negative impacts of salinity on tomato yields. This study will provide insights into the life table characteristics of WFT in tomato fields infected with tomato yellow ring orthotospovirus, aiding in environmentally friendly management strategies.</p><h3>Graphical Abstract</h3><p>Salinity stress affects western flower thrips, <i>Frankliniella occidentalis</i> (Pergande), by affecting food sources, physiology, and behavior, leading to reduced fitness and increased mortality rates.</p>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":8409,"journal":{"name":"Arthropod-Plant Interactions","volume":"19 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994990","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}

The classification relies exclusively on leaf characterisation, without considering gene flow across sympatric taxa. Additionally, it remains unexplored whether different varieties support distinct fig wasp pollinators, or to what extent the floral scents emitted by receptive phase figs of these varieties differ.

To see the correlation between the varieties entered by the fig wasps and the volatile odour compound (VOC) releases from the receptive figs, a headspace solid-phase microextraction and gas chromatography–mass spectrometry analysis were used. The breakdown of one-to-one specificity in fig and fig wasp mutualism occurs when <i>Blastophaga</i> sp. from var. <i>trengganuensis</i> enters another variety (var. <i>kunstleri</i>) apart from its own variety.

However, some buckwheat flowers have been observed opening at night; thus, we can assume that nocturnal insects play a role in buckwheat pollination. Our field observations showed that 80% of buckwheat flowers that opened in the morning remained open at night. The insects visiting buckwheat flowers at night belonged to the moth families of Noctuidae, Crambidae, and Pyralidae. These moths were all found to have buckwheat pollen on their bodies. To quantify the contribution of nocturnal pollinators to seed set, we conducted a pollinator exclusion experiment using the following bagging treatments: no pollinators (bagging for 24 h), only diurnal pollinators (bagging from 18:00 to 06:00), only nocturnal pollinators (bagging from 06:00 to 18:00), and natural pollination (no bagging). The results showed that the seed set decreased in the following order: natural pollination, diurnal pollinators only, nocturnal pollinators only, and no pollinators, with one-fourth of the buckwheat seed sets resulting from nocturnal pollinators. However, the proportion of flowers open at night decreased as the flowering period progress, and the role of nocturnal pollinators appeared to decline over time.
