A Study on the Bamboo Shoot's Damage of Phyllostachys edulis Riv. by Field-mice -Especially on the Inhabitation Environment and Damaged Types of Field-mice-

야서(野鼠)의 맹종죽순(孟宗竹筍) 피해(被害)에 관(關)한 연구(硏究) -야서(野鼠)의 서식환경(棲息環境) 피해형태(被害形態)를 중심(中心)으로-

This study was made on bamboo shoot's damage of Phyllostachys edulis by field mice in Jinju, Gyeongsangnam-do, and grasped the inhabitation environment by the analysis of around and lower vegetation in damaged bamboo stands, and made clear the species of field mice in damaged bamboo stand, the damaged degree and rate, therefore, were put in practice for contribution with damage prevention and extermination. The results were summarized as follows; The damaged degree were influenced by inhabitation environment and stand density around damaged bamboo stands. The damaged degree were shown 4,359.1 g with 7.1 shoots per. ha and the rate 0.23%. The damage season were from the middle of April to the middle and end of May, the most damaged season was about April 23. The length of damaged bamboo shoot was mean 28.12 cm, the inside diameter 7.49 cm, the weight 613.96 g. The damaged type of parts was shown to more numerous overland and surface damaged type of three types; overland, surface and underground damaged type. The field mice to be captured in damaged bamboo stand were three species; Apodemus agrarius coreae, Mus molossinus and Crocidura lasiura, the species of main damage was Apodemus agrarius coreae of captured Rodentia's 2 species. Crocidura lasiura in order Insectivora was found to inhabitate for the first time at southern region in Korea.

본(本) 연구(硏究)는 경남(慶南) 진주지역(晋州地域)에서 발생(發生)한 야서(野鼠)의 맹종죽순(孟宗竹筍) 피해(被害)에 관해서 조사(調査)하여 피해죽림분(被害竹林分)의 주변(周邊)과 내(內)의 식생(植生)을 분석(分析)하고 서식환경(棲息環境)을 파악하여, 피해정도(被害程度)와 피해율(被害率), 가해야서(加害野鼠)의 종류(種類)를 밝혀 피해예방(被害豫防) 및 구제(驅除)에 기여코져 실시하였다. 그 결과(結果) 피해죽림(被害竹林) 주변(周邊)의 입목도(立木度)와 서식환경(棲息環境)에 따라 피해도(被害度)에 영향을 미쳤으며, 피해도(被害度)는 ha당(當) 7.1개(個)로 4,359.1g이었고, 피해율(被害率)은 0.23%이었다. 피해시기(被害時期)는 4월(月) 중순(中旬)에 시작되어, 4월(月) 23일(日)경에 최고에 달하고 5월(月) 중(中) 하순(下旬)에 종료(終了)되었다. 피해죽순(被害竹筍)의 평균장(平均長)은 28.12cm, 직경(直徑) 7.49cm, 무게 613.96g이었으며, 부위별(部位別) 피해형(被害型)은 지상(地上), 지표(地表), 지하피해형(地下被害型) 중에서 지상(地上), 지하피해형(地下被害型)이 많았다. 피해죽림분(被害竹林分) 내(內)에서 포획(捕獲)된 야서(野鼠)는 쥐목(目)에 속하는 등줄쥐와 생쥐, 그리고 식충목(食蟲目)에 속하는 우수리땃쥐 등(等) 3종(種)이었으며 주가해종(主加害種)은 등줄쥐와 생쥐 중 등줄쥐가 많았다. 또한, 우수리땃쥐는 남부지방(南部地方)에 서식(棲息)함이 처음 발견(發見)되었다.
