To bridge this knowledge gap, we undertook a study to investigate mite infestations on freshly captured hawkmoths (Lepidoptera: Sphingidae). From August 2016 to July 2018, we collected samples in the Chapada do Araripe area in the municipality of Santana do Cariri (7°12'33''S, 39°43'22''W, 750 m a.s.l.), Ceará, Northeast Brazil. We attracted and captured sphingids using an artificial light source and then gathered mites from them. Among the 3,690 sphingid specimens collected from 37 species of both sexes, 119 individuals from 18 species were found to be mite-infested-a prevalence rate of 3.3%. We identified four mite species: Prasadiseius donahuei (Prasad), Prasadiseius cocytes (Prasad) (Otopheidomenidae), Callidosoma selmae Costa, Klompen, Santos, Favretto & Pepato, and an unidentified Caeculisoma species (Erythraeidae). Our data revealed the importance of seasonality for both host and parasite populations, and we observed no specific preference for infestation sites. This research recorded several first-time observations: a sphingid infested by two species of otopheidomenid mites, C. selmae parasitizing sphingids, and mites recorded from the legs of sphingids. The species Erinnyis ello ello (Linnaeus) was not only the most abundant but also the most frequently parasitized. This host presented the highest parasitism descriptors. Among the 662 mites identified, 506 were P. donahuei, predominantly infesting E. ello ello. We recommend further research to explore the potential for coevolutionary dynamics between mites and their hosts, examining how host defenses and mite adaptations influence each other over time.","PeriodicalId":12088,"journal":{"name":"Experimental and Applied Acarology","volume":"94 1","pages":"14"},"PeriodicalIF":1.8,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142834738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The species includes bisexual and parthenogenetic lineages. Various aspects of these two lineages, such as their abundance ratio, genetic relationship, and population structure, remain unknown in island environments such as Japan that are isolated from the mainland. Therefore, in this study, 235 individuals were collected across 15 prefectures, and their mtDNA was analyzed to better understand the genetic population structure of this species in Japan. Haplotype analysis of the 631 bp cox1 region revealed the presence of 38 haplotypes, which showed for the first time that a large diversity of haplotypes is present in Japan. In addition, the calculated haplotype diversity was 0.889-equivalent to that reported in the study that examined haplotypes across a larger region in China. This indicates that Japan is a hotspot of genetic diversity of this species. The haplotype network of this species was divided into two major clades, but there were no clear geographical boundaries in the distributions of the haplotypes. However, a qualitative cline was observed in the distribution of sexual lineage, with the parthenogenetic lineage being more prevalent in northeastern Japan and the bisexual lineage being more prevalent in southwestern Japan. Future analysis combining the results of this paper with information from nuclear DNA and large-scale mtDNA analyses would facilitate a more detailed understanding of the population structure and historical distributions of the Asian longhorned tick.","PeriodicalId":12088,"journal":{"name":"Experimental and Applied Acarology","volume":"94 1","pages":"8"},"PeriodicalIF":1.8,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142834718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ticks were collected from vegetation and on birds between November 2021 and December 2023. A possible seasonal activity was observed in the immature stages of I. silvanus, with larvae in autumn-winter and nymphs in spring-summer, consistent with a behavioral diapause. A total of 937 ticks were identified as I. silvanus and confirmed molecularly, 741 host-seeking and 196 parasitizing 49 passerine birds (of 9 species, 6 genera and 5 families). All host-seeking ticks were found in leaf litter in forests dominated by the invasive tree Ligustrum lucidum, suggesting a possible link between environmental changes and the establishment of I. silvanus in this region. The prevalence of I. silvanus on birds was 27.4%, with significant participation of the Turdus genus and new host associations documented. The findings suggest that I. silvanus may be expanding its range, potentially facilitated by environmental modifications, the movement of austral migratory birds (Turdus nigriceps, Synallaxis frontalis and Zonotrichia capensis), and the range expansion of other bird species (Turdus amaurochalinus, Turdus chiguanco and Turdus rufiventris). Therefore, I. silvanus may represent a biological invasion and a potential threat to wild bird populations as a vector of pathogenic microorganisms. Future studies are required to determine the implications this could have.","PeriodicalId":12088,"journal":{"name":"Experimental and Applied Acarology","volume":"94 1","pages":"12"},"PeriodicalIF":1.8,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142817309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development and utilization of symbiotic bacteria in insects show promising potential for enhancing their reproduction, temperature tolerance, resistances to pathogens and insecticides. However, limited research has been conducted on symbiotic bacteria in predatory mites. In Phytoseiulus persimilis, we successfully cultivated a strain of Stenotrophomonas maltophilia, which has been noted for its significant contributions to pathogen control, pesticide and toxin resistance, and nutrition provision in some insect species. To explore the effect of S. maltophilia and its potential application on predatory mites, we fed S. maltophilia to P. persimilis and evaluated the transmission dynamics within mite generations. We examined its impacts on predator fitness and resistances to pesticides, pathogens, and starvation. The results showed that the S. maltophilia content in the offspring increased by 12.91 times when gravid mites were fed with the bacterial solution. P. persimilis that consumed prey treated with S. maltophilia showed a 25.20-fold increase in microbial content. Mating with treated males did not affect microbial levels in females. Moreover, S. maltophilia did not cause any discernible effect on the fitness of P. persimilis, including survival, developmental duration, fecundity, and longevity. Notably, it was found to improve P. persimilis survival following exposure to the pathogen Acaricomes phytoseiuli, resulting in a reduction of mortality by 20% compared to the control. This study serves as a foundational step for further utilization of beneficial microbes to improve the efficacy of predatory mite biological control.","PeriodicalId":12088,"journal":{"name":"Experimental and Applied Acarology","volume":"94 1","pages":"11"},"PeriodicalIF":1.8,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142817295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because hibiscus is a highly traded ornamental plant, CiLV-C2 has the potential to spread. In laboratory experiments, the abundance and distribution of B. yothersi were studied on four varieties of tropical hibiscus. Plants, grown from cuttings, were infested with female mites, and held in environmental chambers (25 °C, 75% RH). After 3 months, the plants were divided into strata representing the top, middle and bottom of the plant. All mites (including eggs) found on the leaves and woody parts (main stems and side branches) were counted, and the surface area of each part calculated. The number and surface area of leaves and woody parts varied between hibiscus varieties; however, the differences between varieties with respect to total number of mites/plant and mites/cm2 were not statistically significant. There were twice as many mites on the woody parts than on the leaves. Most mites were found in the bottom stratum of the plants, and they showed an aggregated spatial distribution. The implications of mite distributions for assessing population sizes of B. yothersi were analyzed with the purpose of optimizing sampling without damaging the plant. The efficient sampling protocol developed is an important tool for managing the vector and thereby the disease.","PeriodicalId":12088,"journal":{"name":"Experimental and Applied Acarology","volume":"94 1","pages":"9"},"PeriodicalIF":1.8,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11638289/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142817294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, proximate factors influencing such overwintering stages remain poorly understood. This study investigated photoperiodic responses and life-stage compositions during winter in a population of Schizotetranychus shii, a specialist of Japanese chinquapin (Fagaceae). The proportion of non-ovipositing females at 20 °C followed a sigmoid curve with increasing photoperiod. The critical day length was estimated as a photoperiod of 11.8 h light and 12.2 h dark (11.8L), which was similar to the natural photoperiod from late September to early October. Although females grown under 10L and 11L conditions never oviposited within 7 days, 90-96% of them started oviposition within 30 days without chilling, indicating shallow reproductive diapause. In the field, all life stages occurred throughout winter, but their proportions varied considerably. The proportion of eggs declined from early October (62%) to early December (12%), as predicted by the critical day length, but steeply increased toward late February (96%), in which only adult females and eggs remained. These findings suggest that short-day conditions in the field do not maintain adult diapause as predicted by the above experiment. In summary, a short photoperiod in October or November arrests oviposition in emerging females, but they commence oviposition during the short-day season when immature stages are still growing. As a result, individuals at all life stages coexist until all immature stages mature in February.","PeriodicalId":12088,"journal":{"name":"Experimental and Applied Acarology","volume":"94 1","pages":"10"},"PeriodicalIF":1.8,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142817316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
