경상북도에 위치한 산림유전자원보호구역내 2개 지역(영주지역의 신갈나무, 울진지역의 소나무)과 경기 포 천시에 위치한 생물권보전지역내 2개 지역(포천지역의 신갈나무와 소나무)에서 2016년부터 2017년까지 함정 트랩(Pitfall trap)을 매년 5회씩 5반복하여 각각 비교하였다. 그 결과 산림유전자원보호구역에서는 27과 106속 160종 2,665개체가 확인되었으며, 종풍부도는 20.28, 종균등도는 0.266, 종다양도는 1.355, 우점도는 0.265로 우점 종은 납작먼지벌레속 sp.2 (Synuchus sp.2)이였다. 또한, 생물권보존지역에서는 16과 49속 77종 4,834개체가 확 인되었으며, 종풍부도는 8.958, 종균등도는 0.301, 종다양도는 1.31, 우점도는 0.669로 우점종은 윤납작먼지벌레 (Synuchus nitidus)였다. 산림의 중요 지역 간에 지표성 딱정벌레의 군집을 비교함으로써 환경변화에 따른 산림 보존 프로그램을 수행하는데 유용한 기초 자료로 활용될 것이다.

In the present study we report a newly recognized crambid species, Sinibotys butleri (South, 1901). Previously, two species, S. evenoralis and S. obliquilinealis, were known from Korea, but now they are belonged to a genus Torulisquama Zhang, 2010, that was newly erected in a recent study. Sinibotys differs from Torulisquama by having: forewing 36－47.5 mm in length and without unscaled areas; male with transtilla covered with setae and editum bearing dense setae; female with ductus bursae relatively broad and short; corpus bursae and signum much larger. We update taxonomic position of these three species accordingly and compare Sinibotys and Torulisquama morphologically. A Key to species, description of adult, male and female genitalia structures are provided with available information such as collection locality, host plant and distribution range for the species.

The species composition of the parasitoid complex and the degree of parasitism by each species were analyzed for Ivela auripes Butler (Lepidoptera, Lymantridae) populations in the increasing phase. Total of 2,177 eggs, larvae and pupae were collected and reared from the Gwangneung forest Pocheon-si, Korea. The most abundant parasitoids from each developmental stage were: a trichogrammatid wasp (Trichogramma kurosuae) from eggs, a braconid wasp (Cotesia melanoscela) from larvae, an ichneumonid wasp (Pimpla disparis) and a tachinid fly (Tachinidae sp.1), each from pupae. 19 other parasitoids, mostly hyperparasitoids, also occurred including Tachinidae sp.2, Pteromalidae sp.1, Ichneumonidae sp.3, and Apechthis capulifera. Illustrations and a list of the species parasitizing of I. auripes are provided.
