During the survey, three heteropteran species, Appasus japonicus, Aquarius paludum, and Ranatra chinensis, were collected. Among these species, water mites were found only on A. japonicus. The water mites were all in a post-larval resting stage and identified as the Hydrachna sp. The mite prevalence or intensity has no relation to the developmental stage or sex of A. japonicus. However, the host individuals infested with Hydrachna sp. were significantly larger than non-infested ones, and the mite intensity on each A. japonicus was apt to correlate with the host body size. Consequently, the Hydrachna sp. is opportunistically parasitic on larger A. japonicus individuals, regardless of the developmental stage or sex of the host. Though the Hydrachna sp. did not exhibit a preference for particular body parts of the juvenile A. japonicus, the mites preferred the forewing to the mesothorax, metathorax, foreleg, midleg, and hindleg of the adult one. The mites probably select large, inactive body parts rather than small, active parts for attachment on the adult host.","PeriodicalId":171325,"journal":{"name":"Journal of The Acarological Society of Japan","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121658116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To test the prediction that T. phaselus is adapted to F. villosa, we investigated the suitability of six host plants available in this species’ habitat. We supplementarily investigated the association between the density of T. phaselus and the density of an important predatory mite, Neoseiulus womersleyi (Acari: Phytoseiidae) on F. villosa leaves to infer the predation pressure. To know the characteristics of host plant use in T. phaselus, these characteristics were compared with the population of the common polyphagous species T. kanzawai on ramie (Boehmeria nivea, Urticaceae) leave. With respect to host-plant suitability, T. phaselus had one of the highest egg production and the survival rate on F. villosa among all six host plants examined, which partly supports the prediction that T. phaselus is adapted to F. villosa. On the other hand, T. phaselus egg production and development time on F. villosa was similar to that of T. kanzawai reared on F. villosa. Nevertheless, T. phaselus was found only on F. villosa in the field, and the density per leaf area of T. phaselus on F. villosa was higher than that of T. kanzawai on ramie leaves. Considering that the density of N. womersleyi was not significantly associated with the density of T. phaselus, the high density of T. phaselus could be partly attributed to the scarcity of N. womersleyi on F. villosa leaves.","PeriodicalId":171325,"journal":{"name":"Journal of The Acarological Society of Japan","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115075244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the development of effective control measures is necessary. The effect of mass-watered soil covered with a plastic film on T. similis densities was tested in the laboratory. Vinyl pots containing soil and released T. similis were mass watered. The soil surfaces of watered pots were closely covered with plastic film, except for the control. The densities of T. similis were significantly lower in the soil of pots that were covered for 10 or 14 d after watering than those in the control; however, no significant differences were found in the plot covered for 7 d. In 2015, the effect of mass-watered soil covered with a transparent vinyl film or a light-shading bilayer mulch film was investigated in three experiments in spinach greenhouses in Hokkaido. Although massive damage to the spinach was observed in plots covered with vinyl for 10 d, in most plots covered with vinyl and bilayer mulch for 14 d, T. similis densities were substantially lower and there was less damage than that observed in the control plots regardless of the soil temperature. However, in the plot where algae grew extensively on the soil during the covering period, T. similis densities increased rapidly and the spinach was severely damaged. Results indicated that mass watering and covering is effective to control mites; however, algal proliferation on the soil could cause mite densities to increase again, as algae is a suitable food source. T. similis density collected was determined the following morning at from 1- to 4-d intervals. The damage to spinach was observed in 25 plants in each repetition at approximately 7-d intervals using the following index: 0, no damage; 1, slightly damaged; 2, slightly deformed; 3, deformed; 4, greatly deformed, dwarfing. The extent of the damage was calculated as follows: {(the sum total of indexes/the number of observed spinach × 4) × 100}.","PeriodicalId":171325,"journal":{"name":"Journal of The Acarological Society of Japan","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133454844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mites feed on bee hemolymph in the tracheas of adult bees. Mite infestations cause serious damage to bee colonies. The distribution of these mites is now worldwide, from Europe to South and North America. The first recorded A. woodi infestation in the Japanese native honey bee, Apis cerana japonica, occurred in 2010. In a previous study, to determine the distribution of A. woodi in Japan, we sampled more than 350 colonies of A. cerana japonica. We found mite infestation from central to eastern Japan. On the other hand, Apis mellifera in Japan has not suffered serious mite damage. Here, to determine the effects of mite infestation on Japanese native honey bees, we investigated seasonal prevalence, mite load in the tracheal tube, and the relationship between mite prevalence and K-wing (disjointed wings). Similar to European honey bees, Japanese honey bees had a high prevalence of mite infestation in winter and a low prevalence in summer. The average mite load was about 21 or 22 mites (all stages) per trachea when all bees were infested by tracheal mites (100% mite prevalence). This mite load did not differ from that in A. mellifera. The K-wing rate was positively correlated with mite prevalence. Further comparative investigations focusing on the mechanisms of infestation will be needed to elucidate the differences in mite susceptibility between Japanese and European honey bees.","PeriodicalId":171325,"journal":{"name":"Journal of The Acarological Society of Japan","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130269089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because there is a paucity of information on eriophyoid taxonomy in Thailand, where the host plants are so diverse, there is a need to investigate the presence of these tiny creatures – especially those species that can be harmful to economic crops. Here, the taxonomy of the eriophyoid mites in the collection of the ﬁrst author was revised, together with the taxonomy of those reported by other researchers. To date, a total of 215 species of eriophyoid mites have been recorded from Thailand. The family Eriophyidae comprises 157 species, whereas only 58 species are reported in the family Diptilomiopidae. These mites are found on 161 plant species under 60 host plant families; they are relatively more numerous ( ＞ 10 species) on plants in the families Fabaceae, Poaceae, Moraceae, Sapindaceae, Rubiaceae, Anacardiaceae, Myrtaceae, and Euphorbiaceae. Fortunately, only a few species are considered to be pests of our economic crops. Eight new genera were assigned as new names for those mites previously identiﬁed by the ﬁrst author and Professor Jan Boczek. Another 8 new genera and 10 new species were also added for unidentiﬁed eriophyoid mites in this collection where Diptilomiopus phylanthi (Chandrapatya, 1992), Liparus eugeniae Boczek, chonburi Chandrapatya, Konvipasruang & Amrine, 2016 for Aculops desmodii Chandrapatya & Boczek, 2000 preoccupied by Aculops desmodii (Keifer, 1964) and Diptilomiopus sakaena Chandrapatya, Konvipasruang & Amrine, 2016 for Diptilomiopus combretae (Chandrapatya & Boczek, 2002) preoccupied by Diptilomiopus combretae Wei & Lu, 2001. words:","PeriodicalId":171325,"journal":{"name":"Journal of The Acarological Society of Japan","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123673225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
