SONE K., TOMIMOTO M., TOKURAKU T., MATSUYAMA K., HATA K., HIGUCHI T., OKABE T. . Improved Method of Applying Non-woven Fabric Strips Inoculated with Beauveria bassiana Conidia to Control Monochamus alternatus (Coleoptera : Cerambycidae) Adults . Journal of the Japanese Forest Society89 ( 4 ) 262 - 268 2007.8

Language：Japanese Publisher：Japanese Forestry Society

In 2004 and 2005, we applied non-woven fabric strips inoculated with Beauveria bassiana conidia (NFS) to infested logs, then covered them in various ways, and compared the mortality of Monochamus alternatus adults emerging from the logs. Covering of the logs with a woven polyethylene sheet (blue sheet, #1500) without openings resulted in a high mortality of adults emerging from the logs. The mortality within 15 days after capture was 86% in Kagoshima and 80% in Sakurajima. Application of NFS increased the adult mortality to 100% and 96% in Kagoshima and 91% in Sakurajima. B. bassiana conidia appeared on 37&sim;100% of captured adults. However, covering of NFS-applied logs with a blue sheet with openings on both cut end sides or at the center of the upper side of log piles reduced the adult mortality to 92% and 86%, respectively. The adult mortality was also high, 96%, when NFS-applied logs were covered with a biodegradable organic sheet. However, the percentage of adults with B. bassiana conidia was low, 21%, suggesting that the high adult mortality might not be mainly caused by infection with B. bassiana. These results indicate that M. alternatus adults can be controlled efficiently by applying NFS to infested logs and covering them with a blue sheet anywhere in Japan.

Tomimoto M., Sone K., Hata K., Higuchi T., Okabe T. . Application of Non-woven Fabric Strips with Beauveria bassiana Conidia to Control Monochamus alternatus (Coleoptera: Cerambycidae) Adults in Southern Kyushu. . Journal of the Japanese Forest Society89 ( 2 ) 79 - 84 2007

Language：Japanese Publisher：Japanese Forestry Society

To examine the applicability of non-woven fabric strips with Beauveria bassiana conidia (NFS) to the control of Monochamus alternatus adults in southern Kyushu, we piled 1 m3 of Pinus thunbergii logs infested with M. alternatus in each of two outdoor cages, and placed 2,500 cm2 of NFS on one of these piles in May 2003. We covered each log pile with a blue vinyl sheet containing two triangular openings (the base: 50 cm, the height: 40 cm) on both cut end sides of the log piles. We captured adult beetles every day and reared them individually to determine the longevity and infection by B. bassiana. Infection by B. bassiana did not affect the average rate of food consumption. By applying NFS, the percentage of adults on which B. bassiana produced conidia increased from 2 to 34 % and the mortality rate of adults 15 days after emergence from 20 to 52 %. These mortality rates were similar to those obtained by the same application test to 0.2 m3 of logs in 2001, suggesting that the dose of NFS per log volume might determine the efficiency of B. bassiana. The mortality rate and infection rate in this study were lower than those reported in Kanto District. We discussed the problems to be solved for the improvement of the efficiency of NFS-application in southern Kyushu.

Hirata R., Takamatsu N., Nakamura M., Fuchigami M., Hata K., Sone K. . Secondary Dispersal of Pasania edulis Acorns by Apodemus speciosus into a Coniferous Plantation. . Journal of the Japanese Forest Society89 ( 2 ) 113 - 120 2007

Language：Japanese Publisher：Japanese Forestry Society

In order to evaluate the role of Apodemus mice in invasion of Pasania edulis Makino into a plantation of Japanese cedar, Cryptomeria japonica D. Don, we studied the primary dispersal of acorns from parent trees, secondary dispersal of acorns by mice, and seedling establishment in the plantation and adjacent evergreen broad-leaved forest at the Kagoshima University Forest from April 2003 to January 2005. By primary dispersal, acorns were dispersed on average 2.4 m from the crown edge of the parent trees, and the maximum distance of invasion into the plantation by primary dispersal was 4.4 m from the border of the forests of two types. Of the 200 magnet-attached acorns we placed in the broad-leaved forest in autumn of 2003 and 2004, mice transported 66 and 58 acorns, respectively, into the plantation. The maximum distance from the border to cache site in the plantation was 34.5 m in 2003 and 18.5 m in 2004. Six acorns cached in 2003 remained intact until the next spring. In the plantation, the density of seedlings decreased with the distance from the border, but within 10 m of the border, the density did not differ significantly from that in the broad-leaved forest. From these results, we concluded that wood mice contribute to the invasion of P. edulis into the plantation as an important seed disperser.

HIRATA R., HATA K., SONE K. . Seed Dispersal by Frugivorous Birds in a Coniferous Plantation . Journal of the Japanese Forest Society88 ( 6 ) 515 - 524 2006.12

Language：Japanese Publisher：Japanese Forestry Society

In order to evaluate the role of frugivorous birds in the dispersal of broad-leaved tree seeds in a plantation of Japanese cedar, Cryptomeria japonica D. Don, we monitored seed rain with 120 seed traps distributed over the plantation and an evergreen broad-leaved forest close to the plantation at the Kagoshima University Forest from October 2002 to April 2004. The numbers of bird-dispersed seeds and their seed species deposited in the traps in the plantation were significantly larger than those derived from naturally fallen fruits. Seasonal and yearly variation of bird-dissemination was observed in the plantation; the frugivorous birds deposited more seeds in the autumn-winter season than in the spring-summer season, and in 2002 than in 2003. In the plantation, naturally fallen fruits were localized around the broadleaved forest, while the bird-dispersed seeds were widely dispersed randomly. We also conducted a bird census in the study area for 43 days from February to December 2003. We observed 14 frugivorous bird species in the study area, and among them, the Brown-eared Bulbul, Hypsipetes amaurotis, was observed most frequently. These results suggest that frugivorous birds, especially H. amaurotis plays an important role in seed dispersal in the conifer plantation.

Language：Japanese Publisher：Kagoshima University

In order to examine the applicability of automatic cameras with an infrared censor switch, we set the cameras to take photographs of mammals and birds in an evergreen broad-leaved forest of Takakuma University Forest of Kagoshima University during the period from December 2002 to December 2004. A total of 1733 photographs were taken of 11 species of mammals such as Apodemus mouse and wild boars, nine species of bird, and some arthropods. We identified the species and in some cases determined the behavior of each individual. Data obtained from photographs revealed the diurnal pattern of activities on the ground surface, the effects of weather conditions, and the characteristics of acorn handling in Apodemus mice. The diurnal and seasonal activities of wild boar in the study site can also be estimated. These results suggest that automatic cameras with an infrared censor switch are promising tools in wildlife surveys.

Language：Japanese Publisher：Kagoshima University

We surveyed the nesting and foraging sites of herons in Tarumizu City and Sakurajima, Kagoshima Prefecture, during the period from March to December, 2004. We observed 7 species of herons, Egretta alba, E. intermedia, E. garzetta, Bubullcus ibis, Ardea cinerea, Nycticorax nycticorax, and Butorides striatus, in the study area. A. cinerea and E. garzetta were observed much more frequently than the other five species of herons. Foraging sites differed among the heron species. A. cinerea and B. ibis had a strong preference for a certain type of habitat and foraged exclusively at fish farms and farmlands, respectively. While, three egrets foraged in various types of habitat, such as fish farms, farmlands, rivers, and tidal flats, but the main foraging sites differed among the three. E. alba and E. garzetta foraged more frequently on fish farms, and E. intermedia foraged mainly in rivers and on farmland. We observed seven colonies/nests in the study area. All colonies and most nests were occupied by two or more species of heron throughout the study period. Colonies were established in stands that seemed to be protected from invasion by natural enemies. Nests were established in stands that were smaller in area than those with colonies and located near to foraging sites of herons. Nests were less stable than colonies. We discuss the way to conserve herons without harmful effects on daily human activities.
