Initially, we examined their physical traits using a microscope and a specific camera and observed differences between the two species. To further validate these distinctions on a molecular level, we designed primers based on mitochondrial genome sequences obtained from the NCBI database. The primers were effectively used in general PCR and loop-mediated isothermal amplification (LAMP) tests. General PCR was successfully performed at 61°C using NC_mt5117F33 and NC_mt5438B33 primers for <i>N. cincticeps</i> and NV_mt3089F31, NV_mt3360B31 primers for <i>N. virescens</i>. The effectiveness of the selected primers was validated using quantitative PCR (qPCR) on the pooled gDNA samples and droplet digital PCR (ddPCR). The best conditions for LAMP were 61°C and time 45 min, resulting in the most favourable amplification outcomes. Additionally, LAMP enables diagnosis at the individual level in the field, and qPCR and ddPCR can be used for relative or absolute quantification, even from pooled gDNA from multiple species. This study emphasises the importance of combining traditional and molecular techniques in primary pest species diagnostics to ensure precise and timely pest control, which can contribute to improved pest management strategies.</p>\u0000 </div>","PeriodicalId":14987,"journal":{"name":"Journal of Applied Entomology","volume":"149 3","pages":"417-429"},"PeriodicalIF":1.7,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143629849","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}

A bibliometric analysis conducted on 368 documents extracted from the Scopus database reveals a historical overview spanning from 1836 to 2023, highlighting significant trends in publication rates and citation counts. Despite a consistent rise in yearly publication rates, citation frequencies have notably declined over time. The analysis further explores geographic trends, with authors from forty-nine countries contributing to the research landscape. Brazil emerges as the leading contributor, followed by the United States and China. Additionally, the study identifies 159 different journals publishing articles on the subject, with the <i>Journal of Economic Entomology</i> leading in publication frequency. The most cited article focuses on the transgenic enhancement of rice plants against lepidopteran pests. Further examination, with an emphasis on factors influencing rearing conditions and behavioural studies, categorises research topics into areas such as basic biology, biological control and ethological control. Clustering analysis reveals distinct research foci, including the study of larval physiology, host–parasite interactions and the genetic basis of biological control strategies such as <i>Bacillus thuringiensis</i> and transgenic plants. Studies focusing on the most common species of Lepidoptera, <i>Spodoptera frugiperda</i>, are also identified. Overall, this review provides a comprehensive overview of the research trends and thematic areas in the field of the rearing of Lepidoptera under laboratory conditions and can be a source of information for researchers interested in this field. This review is limited to the information deposited in Scopus, the number of research studies focused on lepidopteran rearing in laboratories and the low interaction of researchers between countries.

Effective control strategies are crucial to mitigate these losses. This study aimed to elucidate TPB host preferences and reproductive behaviours under various integrated pest management approaches. Experimental arenas with strawberry plants included treatments involving the predator <i>Nabis americoferus</i> (Carayon) (Hemiptera: Nabidae) and trap crops. In each arena, 30 adult TPBs were exposed to different configurations: (i) three strawberry plants, (ii) three strawberry plants with predators, (iii) one strawberry plant alongside two trap crop plants (buckwheat and canola), and (iv) one strawberry plant with the two trap crops and predators. TPB distribution among the arena, plant species and plant sites (flower, stem and adaxial and abaxial leaves) were monitored over 72 h. One week later, adults were removed and the number of emerged first instar nymphs (L1) was recorded three times postexperiment. The results indicate a preference shift in TPB behaviour influenced by plant diversity and predator presence. TPBs exhibited a reduced presence on strawberries when trap crops were introduced, with canola as a preferred plant. This preference for canola was supported by higher TPB offspring counts. Conversely, buckwheat, although less preferred, contributed to diluting TPB populations across plant species. The introduction of <i>N. americoferus</i> showed dual effects: While reducing TPB oviposition on canola, it increased TPB presence on strawberries, highlighting the importance of nonconsumptive effects (NCEs) of predators in agroecosystems. Nonetheless, the combination of canola as a trap crop and <i>N. americoferus</i> as a predator effectively reduces TPB presence on strawberry flowers, essential for fruit development. This approach shows promise when integrated with other strategies, such as vacuuming and pheromone-enhanced coloured traps.</p>","PeriodicalId":14987,"journal":{"name":"Journal of Applied Entomology","volume":"149 3","pages":"372-383"},"PeriodicalIF":1.7,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jen.13389","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143629903","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}

This review synthesises current knowledge on wasp pollination's ecological and evolutionary dynamics. For clarity, I classified wasp pollinators into three categories: (1) generalist pollinators associated with resource-rich plants, (2) specialised pollinators of resource-rich plants and (3) specialised pollinators of resource-less plants (deceptive pollination). The latter category includes sexual and food deception. These pollination types will be described in detail throughout the text. Generalist wasps pollinate flowers with less morphological specialisation, which are also visited by other insect groups. In contrast, certain groups, such as the subfamilies Masarinae and Thynninae, the genus <i>Hemipepsis</i> (Pompilidae) and the family Agaonidae (fig wasps), have specialised in certain taxa or plant guilds. Deceptive pollination strategies, primarily in orchids, exploit wasps through sexual and food mimicry, reflecting intricate evolutionary adaptations. Fig wasps exhibit a long history of co-diversification with their host plants, presenting a key innovation that combines wind-mediated and chemotactic pollen dispersal. This review highlights the ecological implications and evolutionary aspects of wasp pollination by examining these diverse mechanisms.
