잎갈나무통나방의 생활사
초록
일본잎갈나무의 식엽해충인 잎갈나무통나방(Coleophora obducia Meyrlck)의 생활사 및 천적의 종류를 충북지방을 중심으로 조사하였다. 기주식물로는 일본잎갈나무만이 확인되었다. 잎갈나무통나방은 연 1회 발생하였으며 성충의 우화시기는 5월 중순부터 하순까지였고 최성기는 5월 14일경이었다. 성충 1마리당 포란수는 약 44.5개였으며 1엽당 1개씩의 알을 낳았다. 난기간은 약 2주 였고 유충은 잎 속에다 고치를 틀고 월동하였고 4월 말부터 용화하기 시작하였다. 또한 천적으로 포식성곤충인 거미류, 개미류 등과 기생성곤충인 기생파리류와 기생벌류가 조사되었다.
Bionomics of Coleophora obducia(Lepidoptera: Coleophoridae)
Abstract
The life history and natural enemies of Coleophora obducia Meyrick which is a defoliating pest of Larix leptolepis were studied mainly in Chungchongbuk Province. Larix leptoiepis was the only host plant of this pest. Coleophora obducia had one generation per you and the adults emerged from mid May to late May with a peak emergence around May 14th. The mean number of eggs in an ovary was 44.5 and most females oviposited one egg on each needle. The duration of the egg stage was about two weeks. Larvae passed the winter in a pouch made by spinning the needles. Pupation began in the late April, and the pupal period was two weeks on average. The natural enemies observed were parasitoids and predators.
