Microorganisms play essential roles in bark beetles, including nutrition, fitness as well as in overcoming host defenses. Here, we performed high-throughput 16S rRNA metabarcoding of I. typographus across different populations in Europe, to assess its bacterial community. We investigated four postglacial refugial areas in Europe and focused specifically on a current bark beetle hot spot in the Dolomites where we compared populations with different epidemiological phases (outbreaking vs. non-outbreaking) and across different seasons (pre-overwintering vs. overwintering). Our results show that the bacterial community structure varied among populations from the refugial areas and between different regions within the Dolomites. We found a significant difference in the bacterial community between pre-overwintering and overwintering individuals, but we did not find differences between epidemic and endemic populations. The prevalence of the genera Erwinia (which was present in all individuals) and Pseudoxanthomonas (present in almost all individuals) across all populations suggests that these taxa form the core bacterial community of I. typographus. Furthermore, several additional bacterial taxa occurred in all populations, but with variable frequencies. This study highlights a complex interaction of I. typographus and various bacterial taxa across different regions and ecological phases and provides new insights into the role of microorganisms in the biology of this important pest species.","PeriodicalId":11728,"journal":{"name":"Entomologia Generalis","volume":null,"pages":null},"PeriodicalIF":6.9,"publicationDate":"2024-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139948858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bagrada hilaris is a worldwide invasive pest of crops in the family Brassicaceae. The present study aims to evaluate the parasitoid’s host range in a European context. These tests complement studies underway in California and provide risk information for a potential release of G. aetherium in southern continental Europe where B. hilaris is likely to spread in the future. Of the 11 non-target species tested, four pentatomids were in the physiological host range of G. aetherium: Carpocoris mediterraneus, Dolycoris baccarum, Graphosoma italicum and Ancyrosoma leucogrammes. Parasitism rates on these four species were lower in choice than in no-choice conditions. Surprisingly, the three Eurydema spp. that belong to the same tribe as B. hilaris (Strachiini) and feed on plants in the family Brassicaceae were not parasitized. No parasitism was observed on the cosmopolitan invasive pentatomids Nezara viridula and Halyomorpha halys, nor on the rhopalid Liorhyssus hyalinus. Parasitoids that developed from non-target species were larger than ones developing on B. hilaris and took more time to complete development.","PeriodicalId":11728,"journal":{"name":"Entomologia Generalis","volume":null,"pages":null},"PeriodicalIF":6.9,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139949133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to its unique insecticidal mechanism and environment-friendly characteristics, it has received increasing attention in recent years. There are many species that can be used as trap plant, but few of them can be used as dead-end trap plants. These plants are commonly utilized for lepidopteran pest management in graminaceous crops, cruciferous vegetables and other cropping systems. At present, vetiver grass, Chrysopogon zizanioides, is widely used in the integrated pest management (IPM) of rice borers in southern China as an alternative to chemical pesticides. This article lists plant species that can be used as dead-end trap plants, together with the target pests and relevant cropping systems. In addition, the trapping principle and insecticidal mechanism of dead-end traps is reviewed, and the application of vetiver grass as a dead-end trap in rice borer IPM introduced. The future research directions of dead-end trap plants towards the protection of crops are also discussed.","PeriodicalId":11728,"journal":{"name":"Entomologia Generalis","volume":null,"pages":null},"PeriodicalIF":6.9,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139769327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, little is known about the determinants influencing bee preferences among buzz-pollinated flowers. We studied five co-flowering, nectarless species of Pedicularis (Orobanchaceae) buzz-pollinated by bumblebees in an alpine meadow, to investigate bumblebees’ flower preferences in response to fluctuations of floral abundance across five years. We also recorded and analyzed the buzzing frequencies produced by the three dominant bumblebee specie. Our results indicate that Bombus friseanus and B. lepidus visited different Pedicularis flowers using similar buzz frequencies and displayed an abundance-dependent flower preference across years. These two bumblebee species had staggered phenologies with distinct timing of peak abundances across the five years. In contrast, B. festivus used lower fundamental buzz frequencies, had a constant flower preference across years, but used different buzz frequencies across Pedicularis species. Although the amount of pollen released after bumblebee visitation varied across Pedicularis species, we found that after a single visit all bumblebees deposited similar amounts of pollen on stigmas. Our study indicates that bumblebees’ flower preferences is sometimes, but not always, modulated by floral abundance, and that at least one bumblebee species was observed to produce buzzes of different frequencies in different plant species. Competition for floral resources among bumblebees and for pollination services among co-flowering Pedicularis species may structure plant-pollinator interactions and affect species coexistence.","PeriodicalId":11728,"journal":{"name":"Entomologia Generalis","volume":null,"pages":null},"PeriodicalIF":6.9,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139773531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, the reliance on chemicals has negatively affected human health, biodiversity, and the environment. Therefore, the development of eco-friendly alternatives is highly encouraged to replace hazardous chemical pesticides. Inhibitory cystine knot (ICK) peptides have a leading future as they present a narrow spectrum activity, and remarkable stability, making them promising bio-insecticide modalities against pests of crops of economic importance. In this study, the impact of Pea albumin 1-b (PA1b), a plant ICK peptide extracted from seeds of peas (Pisum sativum, Fabaceae) was investigated through foliar application to be delivered to 2nd instar larvae of T. absoluta. However, due to the failure of delivery upon foliar application, microinjections of the peptide into 3rd instar larvae were performed to assess the insecticidal activity of PA1b when being into the body cavity of the larvae. Toxicity bioassays were conducted in Petri dishes in a developed experimental arena that allowed us to easily survey the status of the larva and the leaf for up to 18 days. Our study showed that PA1b has a significant toxic effect against T. absoluta when delivered through injection. Further studies must be conducted to optimize the administration of PA1b into the larvae of T. absoluta, investigate the binding sites of the peptide in this pest, and ascertain the insecticidal capacity of such a peptide at an agricultural-relevant scale.","PeriodicalId":11728,"journal":{"name":"Entomologia Generalis","volume":null,"pages":null},"PeriodicalIF":6.9,"publicationDate":"2024-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139553883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
