기생벌(parasitoids)은 기주곤충의 다양한 발달단계에 특징적(내부 또는 외부)으로 기생한다. 이러한 기생벌은 적어도 10만종 이상이 존재하며 해충방제를 위한 중요한 천적자원으로 활용된다. 본 연구에서는 배추흰나비 번데기의 내부에 기생하는 기생벌을 채집하여 그 형태 및 분자생물학적 분석을 실시하였다. 기생벌의 cytochrome oxidase subunit I (COI) 염기서열을 결정하고 NCBI database에서 비교 분석해 본 결과 Pteromalus venustus와 가장 높은 유사성 (91%)을 나타냈다. 국내에는 금좀벌과(Pteromalidae)에 24속 33종이 보고되었고 그 중 Pteromalus 속에는 오직 배추벌레 살이금좀벌(P. puparum) 단 1종이 기록되었다. 그러나, P. puparum의 COI 염기서열 정보는 보고된 바 없다. 그리고 P. puparum은 배추흰나비에 기생하는 반면에 P. venustus는 벌의 일종인 Alfalfa leaf cutting bee인에 기생한다. 본 연구결과 채집한 기생벌은 P. puparum으로 판단되며 처음으로 이종의 COI 염기서열을 보고한다. 또한, 배추흰나비의 친환경적 방제를 위하여 배추벌레살이금좀벌을 천적자원으로 활용할 수 있다.

The current study aims to segment Chinese female consumers using their lifestyle dimensions in the cosmetics market, and analyze their cosmetics purchasing behavior based on that segmentation. Specifically, lifestyle groups were examined to see if there is any group difference(s) in consumer behavior for Korean cosmetics. Lifestyle groups were examined based on: consumers’ demographic characteristics, perceived brand attributes, loyalty toward Korean cosmetics, usage of Korean cosmetics products, preferred stores of shopping for Korean cosmetics, and use of information sources in purchase decisions. An online survey was administered to female consumers who live in Beijing and Shanghai. A total of 493 surveys were used for data analyses. The results of the study were as follows: First, factor analysis revealed 11 significant lifestyle dimensions. Second, using these 11 lifestyle dimensions, cluster analysis was conducted, which revealed four distinct groups of consumers: (1) “timid inactive group,” characterized by having low scores in most lifestyle dimensions; (2) “showcase goers,” who tend to be highly fashion/appearance-conscious and brand-oriented; (3) “practical buyers,” who tend to be price-conscious, sensitive and timid; and (4) “sensible buyers,” who enjoy finer meals and wellbeing lifestyles, as well as hardworking in everything and impulse-buy things. Third, consumer behavior of purchasing Korean cosmetics brands were examined; significant differences among the four lifestyle groups were found. The study concludes with a discussion of the results and practical implications.
