본문내용

1) 솔수염하늘소의 생태와 생활사

성충은 체장 3~5cm정도의 갈색의 하늘소로서 등판에는 갈색과 회색의 얼룩무늬가 있고 촉각이 길다. 년 1회 발생하며 난지에서는 5월중순경부터 7월에 걸쳐 성충이 발생하여 새순의 껍질을 갉아먹는다. 발생이 심할 때에는 이로 인하여 가지 끝이 말라 죽는 것이 눈에 띠게 된다. 암컷성충은 교미한 후 수간에 구멍을 뚫고 산란한다. 부화유충은 처음에는 나무껍질 밑을 먹고 자라는데 늦가을이 되면 재부에 공도를 뚫고 심부에 들어가서 월동한 후 이듬해 봄에 번데기 집을 만들어서 용화한다.
유충은 체장 4cm내외, 다리가 없으며 가늘고 긴 벌레다. 공도에는 거친 톱밥과 비슷한 벌레똥을 채워놓는다. 성충의 우화탈출공은 원형으로서 직경 1cm정도다.

2) 솔수염하늘소의 피해 및 특징

이 종은 소나무 재선충의 전파자로서 중요한 역할을 하는 해충이다. 대개 쇠약한 나무의 껍질 밑에 유충이 파고 들어가서 식해하기 때문에 피해를 입은 나무는 급격히 말라버린다. 노숙유충은 수간 내에 공도(孔道)를 만들고 그 속에서 용화되기 때문에 나무껍질을 벗겨도 그 존재를 알 수 없는 경우도 있다.
