<Synopsis>The hermit beetle, Osmoderma opicum Lewis, 1887 is one of the endangered beetle species living in tree hollows. We found the beetle in a warm-temperate evergreen forest on Mt. Kasugayama. This beetle has been thought inhabiting a summergreen forest zone and the coniferous trees zone of the high altitude. Therefore, it was the first time to prove that the beetle can inhabits in a warm-temperate evergreen forest.

[Synopsis] We found large numbers of the exotic millipede, Chamberlinius hualienensis, which is originally distributed in Hualien, Taiwan, from two areas in Wakayama Prefecture. Because there was no trace of a large amount of soil or plants brought into the study sites, and the millipede was univoltine, these populations suggested their invasion was not recent in Wakayama Prefecture. The density of the millipede was 9.5±8.1 ind./m2 in the forest in Tanabe City. Its density was lower than observed when outbreaks occurred in Kanagawa and Okinawa Prefectures (1/6- 1/54 times). Therefore, it was considered that there was no outbreak of millipede at this site at this time. This is the first report showing the possibility of the millipede has invaded in the Kinki region in Central Japan.

[Synopsis]An exotic terrestrial slug, Limax flavus had been found from Nara park. Their main habitat was an old rock wall and its surrounding in Nara Park. The Limax flavus individuals were living with the other slug species, Meghimatium bilineatum on the same rock wall, but Ambigolimax valentinus was seldom observed in the habitat of Limax flavus.

[Synopsis]A deadly poisonous fungus, Podostroma cornu-damae has occurred in Satoyama forest surrounding Nara Campus of Kindai University. This is first record of this fungus in the forest of our campus, and it need to call not to touch this fungus indiscriminately.

[Synopsis] There are no reports of the ant fauna at the Kindai University Faculty of Agriculture, and there is a lack of records for the ant fauna in Nara Prefecture. Therefore, we surveyed them around the campus and searched the past records in literature in Nara Prefecture. As a result, 66 species including 9 rare species and 4 alien species were recorded. The ant fauna had larger species number than the surrounding area and it was species composition including species living diverse habitat. This result suggests that the ant fauna is influenced by the unique environment of the campus that includes Satoyama forest and artificial environment.

[Synopsis] The distribution of Opisthoplatia orientalis had been restricted naturally in the southern part of Kyushu, Ashizuri-misaki Cape in Shikoku, and the Nansei Islands in Japan. However, the cockroach has expanded its distribution area to various parts of Japan in recent years with transplantation of plants such as cycads. We found large numbers of the cockroach individuals comprised the both larvae and adults at two places in the Nanko area of the Port of Osaka in Japan in 2017 through the field surveys based of the eyewitness information of the remains of the cockroach in there in 2015. This is the first report to suggest the cockroach has established in Osaka prefecture.

[Synopsis] The hyaluronidase, elastase and collagenase inhibitory activities of twenty species of vegetables were measured to evaluate their anti-wrinkle and anti-inflammatory capabilities. Among the tested vegetables, Manganji pepper, Takagamine pepper and kohirabi had the high elastase inhibitory activity although high hyaluronidase and collagenase inhibitory activities were not detected.Manganji and Takagamine peppers are classified into the same genus (Capsicum). It suggested that Manganji pepper, Takagamine pepper and kohirabi had the high anti-wrinkle capability and that the capability might be species-specific.

〈Synopsis〉In captive environment, reproductive characteristics of seven bitterlings (Tanakia lanceolata, T. limbata, Acheilognathus rhombeus, A. cyanostigma, A. melanogaster, A. tabira jordani, and A. t. tabira) were estimated by the breeding experiments with Schale's method. Major interspecific difference were confirmed on the spawning pattern and survival rates to emergence from hatching. Some different initial growth patterns were observed in some closely-related Acheilognathus spawning in spring. Such abnormalities as deformation of yolk sac or vertebrae were observed. The achievements would be contributed to ex situ preservation as well as in situ conservation and even taxonomical studies.

<Synopsis>Outbreak of gypsy moth occurred in Nara campus of Kinki University in 2012 and May in 2013 and the outbreak have rapidly declined in June 2013. Many larvae dead on lower portion of tree trunks showing typically attached by their prolegs with their head pointed downward. Spore production of entomopathogenic fungus, Entomophaga maimaiga was observed on some larval body surface. But majority of the larvae showed no external and internal sporulation, and 25% of them contained one or two dipteran larvae. These observations suggested that many larvae of the moth were killed by viral infection, such as baculovirus. The larvae survived the attack by parasitic organisms got pupae, but most of them were killed by parasitic wasps and did not emerge. These facts showed the complex of parasitic organisms, such as virus, fungus, and parastoid diptera and wasps caused the decline of gypsy moth outbreak in Nara campus of Kinki University.

[Synopsis]Degradation of the Philippines’ coastal environment with economic growth is expected to negatively impact tidal flat inhabiting mollusks. But there are few studies investigating local changes in quantity and species composition of Philippine tidal flat mollusks. This study surveyed the quantity and species composition of tidal flat mollusks at several coastal sites and those being sold at the local markets of the Visayas, Philippines, compared the results between sites and against previous studies, and estimated current resource quantity and ecological status of the tidal flat habitat. The total volume of mollusks sold in Cebu –significantly, mollusks from mangrove and freshwater habitats have decreased as compared to 30 years past. No change in volume was found in Dumaguete, Negros Island. The results indicate decreasing population and species number of mollusks in the tidal flats of Cebu possibly caused by worsening coastal degradation due to widespread urbanization of the island. This study suggests implementation of mollusk resource management and prevention of further coastal environment disturbance and over-exploitation of coastal resources in the Visayas, Philippines.
