  • Phylogenetic relationships were analyzed among bumblebees using a portion of mitochondrial (mt) 16S ribosomal RNA (16S rRNA). Eight species of true bumblebees and one species of cuckoo bumblebee (Bombini, Apidae), collected from Korea were included in the analysis. Also, one species of true bumblebee imported from several foreign countries for pollination was included. The length of mt 16S rRNA sequence ranged from 496 bp to 508 bp and sequence divergence ranged from 1.4% (7 bp) to 15.49% (77bp). As expected, a high A+T content was observed (78.5% on average). According to the phylogeny tree derived from parsimony and maximum likelihood analysis, a monphyletic Bombus species, excluding a single cuckoo bumblebee, Psithyrus coreanus, was obtained, but the bootstrap estimate at the node supporting the monophyletic group was very weak (40% or 46%), suggesting a very close relationship of the cuckoo bumblebee to the true bumblebee. Within Bombus species belonging to identical subgenera subgeneric specific clustering was formed with high bootstrap values, implying validity of the subgeneric names of each species: Pyrobombus for B. ardens and B. modeatus; Megabombus for B. consobrinus wittenburgi and B. koreanus; and Bombus s. str. for B. ignitus, B. hypocrita sapporoensis, and B. terrestris.

  • 뒤영벌 인공수정기를 본 연구에서 처음으로 개발하였다. 개발된 뒤영벌 인공수정기는 자리잡기용관, 이송용관, 고정관, 머리받침대, 생식기 탐침기 등으로 구성되어 있으며, 여왕벌의 인공수정에 따른 스트레스 및 생식기의 손상을 최소화하도록 고안되었다. 특히 인공수정기의 조정핸들은 지렛대 원리를 이용하여 미세하고, 정확하고, 신속하게 조작할 수 있다. 본 인공수정기를 이용하여 인공수정 시 수정 성공률은 90% 이상이었다. 따라서 이 인공수정기는 우량형질의 뒤영벌 육종 및 보존에 효율적으로 이용되어질 수 있을 것이다.

  • Slow Bee Paralysis Virus (SBPV)는 꿀벌 그리고 뒤영벌의 병원성 바이러스로써, 벌의 앞발을 마비시킴으로 폐사를 야기한다. 본 연구는, 뒤영벌에서 빠르게 SBPV 검출하고자 SBPV 특이 초고속 PCR법을 개발한 것을 보고하는 것이다. SBPV 특이 초고속 PCR은 제반 조건을 최적화한 후, $1.0{\times}10^8$ 분자의 SBPV 특이 유전자의 존재를 3분 35초 만에 인식할 수 있었으며, 최소 $1.0{\times}10^1$ 분자의 DNA까지 정량적으로 측정할 수 있었다. 한편, 국내외에서 생산된 뒤영벌을 시료로 SBPV 특이 초고속 역전사 PCR을 시행하였으며, 수입된 뒤영벌과 국내생산 뒤영벌 1종에서 SBPV가 존재함을 보일 수 있었다. 국내 처음으로 뒤영벌에서의 SBPV의 존재를 확인한 것이다. SBPV 특이 유전자 초고속 역전사 PCR법은 실험실 내에서 뿐만 아니라 현장에서 정량적 검출을 하기에 유용한 방법이 될 것이며 더 나아가 뒤영벌 수출입을 위한 검역 기준을 이용하여 집단적 발병 방지에 기여하기를 기대한다.

  • The large bumblebee $Bombus$ $terrestris$, indigenous to Europe and adjacent areas and used extensively for high-value crop pollination, has been artificially introduced to several parts of the world. Here we show the occurrence of interspecific hybridization between the bumblebee species $B.$ $hypocrita$ $sapporoensia$ and $B.$ $terrestris$ under laboratory conditions. The mating and oviposition percentages resulting from the interspecific hybridization of a $B.$ $terrestris$ queen with a $B.$ $h.$ $sapporoensis$ male were higher than those resulting from the intraspecific mating of $B.$ $h.$ $sapporoensis$. Furthermore, a competitive copulation experiment indicated that the mating of $B.$ $h.$ $sapporoensis$ males with $B.$ $terrestris$ queens was 1.2-fold more frequent than the mating of these males with $B.$ $h.$ $sapporoensis$ queens. The interspecific hybridization of a $B.$ $terrestris$ queen with a $B.$ $h.$ $sapporoensis$ male produced either $B.$ $terrestris$ workers or the $B.$ $terrestris$ male phenotype, and the hybridization of a $B.$ $h.$ $sapporoensis$ queen with a $B.$ $terrestris$ male produced $B.$ $h.$ $sapporoensis$ males. Our results indicated that interspecific hybridization occurred between $B.$ $h.$ $sapporoensis$ and $B.$ $terrestris$. These results suggest that such hybridization will have a negative competitive impact and will cause genetic contamination of native bumblebees.

  • We have cloned and characterized a lipocalin from the bumblebee Bombus ignitus (Bi-lipocalin). The Bi-lipocalin gene spans 2284 bp and consists of four exons coding for 270 amino acid residues. Sequence analysis revealed that Bi-lipocalin possesses three structurally conserved regions (SCTs) that characterize lipocalins. Recombinant Bi-lipocalin, expressed as a 37 kDa protein in baculovirus-infected insect cells, was N-glycosylated, indicating that the carbohydrate moieties are necessary for secretion. Tissue distribution analysis revealed ubiquitous expression of Bi-lipocalin in all tissues examined. Bi-lipocalin transcripts were upregulated by stress, such as wounding, $H_2O_2$ exposure, and external temperature shock. These results indicate that Bi-lipocalin is a stress-inducible protein that acts on wounding, $H_2O_2$ overexposure and temperature stimulation.

  • In this study, we prepared alcohol extracts of the larva, pupa, queen, and cocoon (clony) of B. ignitus, B. terrestris, and B. h. sapporoensis, and tested the anti-inflammatory activity of the extracts by using a rat model of adjuvant-induced edema. The extracts derived from the queen of B. ignitus, the queen of B. terrestris, and the cocoon of B. ignitus decreased hind paw edema after 1 day of i.p. administration. These extracts also induced vasorelaxation and NO production in calf pulmonary artery endothelial cells. These results suggest that bumblebee alcohol extracts has anti-inflammatory and vasorelaxant properties.

  • 본 연구는 69종의 농약(살충제 41종, 살균제 18종, 살비제 10종)에 대한 꿀벌(A. mellifera)과 서양뒤영벌(B. terrestris)에 급성독성과 잔류독성을 평가하였으며, 국제 생물적 방제기구(IOBC)의 기준에 따라 30% 이하를 독성이 없음으로 분류하였다. 급성독성실험에서 41종의 살충제 중에 acetamiprid, chlorfenapyr, thiacloprid, milbemectin, buprofezin+amitraz 5종이 꿀벌에, methomyl, thiodicarb, acetamiprid, chlorfenapyr, thiacloprid, abamectin, spinosad, buprofezin+amitraz 8종은 서양뒤영벌에 대해서 독성이 낮아 안전하였다. 그리고 살균제 18종과 살비제 10종은 꿀벌과 서양뒤영벌에 대해 모두 안전하였다. 잔류독성실험에서 41종의 살충제 중 꿀벌에 대해서 약제처리 3일 이후부터 안전한 약제는 8종 (dichlorvos, methomyl, imidachlorprid, emamectin benzoate, spinosad, cartap hydrochloride, chlorfenapyr, endosulfan) 이고, 11일차까지도 독성이 높은 약제는 16종(dimethoate, fenitrothion, fenthion, methidathion, phenthoate, pyraclofos, fenpropathrin, clothiamdin, dinotefuran, thiamethoxam, abamectin, acetamiprid+ethofenprox, acetamiprid+indoxacarb, bifenthrin+midacloprid, ethofenprox+phenthoate, imidacloprid+methiocarb)이었다. 서양뒤영벌에 대해서는 약제처리 3일 이 후부터 안전한 약제는 8종(dimethoate, methidation, a-cypermethion, ethofenprox, indoxcarb, chlorpyrifos+a-cypennethrin, esfenvalerate+ fenitrochion)이고, 7일차까지도 높은 독성을 나타낸 약제는 8종(pyraclofos, clothianidin, thiamethoxam, fipronil, acetamiprid+ethofenprox, chlorpyrifos+bifenthrin, ethofenprox+phenthoate, imidacloprid+methiocarb)이었다.

  • We investigated oviposition and colony development of Bombus ignitus and B. terrestris depending on different pollen. In five kinds of pollen blend, the colony development in fresh-freezing pollen blend produced in Korea (Korea-FFP) was the best performance, although egg-laying characteristics is lower than that of pollen blend for oviposition imported from Korppert company (Kopport-FOP). The Kopport-FOP proved that it was suitable to use for oviposition of bumblebees. The Korea-FFDP, freezing dried-fresh pollen blend produced in Korea, is lower rather than the Korea-FDP although it is similar to the KopportFOP in colony development. It is not efficient to use commercial pollen for bumblebee because it is expensive in cost. The dried pollen blend for honeybee feeding imported from China (China-DP) was not suitable for rearing of bumblebee because it did not form colony although the worker emerged. In types of pollen, the oviposition and colony development of B. ignitus were not affected by the fresh-freezing pollen and dried-freezing pollen. This result also indicated that dried pollen, dried in the shade for 5 - 6 days, is possible to use as commercial pollen for bumblebee reproduction.
