굴파리과에 기생하는 종으로 알려진 Bitomus (갗고치벌속)는 한국에 4종 보고되어있다. Bitomus는 Fischer (1987, 1994)에 의해 개정되었 고, Papp (1978, 1981)에 의해 한국에서 보고되었다. Bitomus는 움직이지 않게 연결된 마치 껍질과 같은 2-3번째 또는 4번째 복부마디로 다른 속들 과 구별된다. 본 조사연구 결과로 Bitomus indicus를 국내 최초로 보고한다. 기술과 진단형질도판을 수록한다.

Rhogadopsis속은 주로 굴파리에 기생하는 고치벌로 Opius속의 아속으로 여겨져왔다. 그러나 시맥의 형태와 단계통 분기군을 형성함에 따라 Rhogadopsis속은 속으로 격상되었다. 전라남도 여서도에서의 동물상 조사 결과, Rhogadopsis obliqua의 수컷 표본을 쓸어 잡기로 채집되었다. Rhogadopsis obliqua의 기술과 진단 형질 도판을 수록한다.

Some solitary wasps and bees exhibit peculiar structures, i.e., acarinaria, which are invaginated chambers harbouring certain mite species for transfer to brood cells of hosts. Acarinaria have long been considered morphological adaptations that evolved to securely transfer beneficial mites into nests but there is little compelling evidence to support this hypothesis. The dispersal deutonymphs of the mite Ensliniella parasitica are housed in acarinaria of the host A. delphinalis during phoresy. The mite life cycle has been investigated in detail; the deutonymphal mite using acarinaria invades into a host cell during wasp oviposition, the tritonymph feeds on heamolymph from lepidopteran prey, then adults from the juvenile host, the female begins laying eggs on the host after the host pupates, and larvae and protonymphs acquire nutrition from the pupa, developing into deutonymphs by host eclosion. Although totally parasitic to the juvenile host throughout its life cycle, the mite did not negatively affect on the host. Nests were sometimes infested with other natural enemies, which included a parasitoid wasp (Melittobia acasta), a kleptoparasitic fly, and unknown pathogens. When the parasitoid and adult mites co-existed in a host cell, we found that either all mites or all parasitoids died. A single adult parasitoid (female) and adult mites were placed in transparent acrylic tubes containing a single prepupal host. In some cases, the parasitoids harbouring mites eventually died. However, in other cases, the parasitoid counterattacked mites by possibly biting them on their dorsum. This experiment demonstrated that the probability that the parasitoid was killed depended on the number of mites. Although mutualisms to protect a partner are common, this wasp-mite interaction is exceptional, because the mite is non-predacious and much smaller in body size than the enemy but protects the host wasp.
