이탈리안벌인 A, C, F계통과 코카시안벌인 D, V계통을 2005년부터 2007년까지 국내에서 수집하였다. 수집한 계통은 육종을 위해 격리 된 섬에서 근친교배를 통해 순계로 분리하였다. 이 연구는 꿀, 로열젤리 다수확계통 선발에 있어 개체군 선발과 육종 효율을 높이기 위해 수행되 었다. 23 개의 형태학적 특성을 평가하고 두 아종의 기존 데이터와 비교한 결과, 이탈리안벌 순계계통은 코카시안벌 순계 계통과 달리8개의 특성이 기존의 이탈리안벌과 유사해 더 많은 특성이 보존되고 있음을 알 수 있었다. 또한 국내에서 유지되고 있는 순계들은 타 지역의 동일 계통과 차 이를 보여 분리된 순계의 형태적인 특징이 확인되었다.

South Korea has over 0.38 million of managed honey bee (Apis cerana) colonies before 2009 years ago, which produce the highest quantity of honey in the Korea; however, almost colony (90%) were collapsed by Korean Sacbrood Virus (KSBV) in South Korea. Korean Sacbrood Virus (KSBV) is the pathogen of A. cerana Sacbrood disease, which poses a serious threat to honeybee A. cerana, and tends to cause bee colony and even the whole apiary collapse. Colony collapse of A. cerana was first reported on the Pyeong-Chang of the South Korea in 2009. Several scientists and governments has been tried research for cure the sacbrood disease in A. cerana colony by medicines and management techniques. Unfortunately, The sacbrood disease dosen’t improve. So, we were developed a better breed of A. cerana for resistance of sacbrood virus by selection and then artificial insemination. A. cerana breeding technique was first successful applied with A. cerana in Korean. Queens was grafted from sacbrood resistance line and then it was growing in sacbrood disease colony that was survived 100%. Altogether selected 18 queens were artificially inseminated and 2,000 drones of A. cerana in Korea was used to evaluate amount of semen collection. We are select two scabrood resistance A. cerana line (R and H). R line be used for rearing the Queen. Drone was reared in H line colony. The RH hybrid were not infected sacbrood virus even spread sacbrood virus (2×106). RH colonies have very excellent hygienic behavior, brood, and sacbrood disease resistance activity.

Gryllus bimaculatus is one of many cricket species known as field crickets. Also known as the African or Mediterranean field cricket or as the two-spotted cricket, it can be discriminated from other Gryllus species by the two dot-like marks on the base of its wings. G.bimaculatus is a subtropical insect and widely distributed from Africa to south Asia. After into the country, The species are popular for use as a food source for insectivorous animals like spiders and reptiles kept as pets. In 2016, G.bimaculatus was approved as a general food ingredient by Korean Ministry of Food and Drug Safety. However, domestic research on G.bimaculatus is still in its study is beginning stages. G.bimaculatus is possible species to year-round rearing without storage condition. but The aim of the present study prepares for in case of problems such as breeding space, labor cost etc. In the laboratory condition at 28±2℃ and 50% relative humidity under 10h light, 12h dark photoperiod, Adult crickets oviposit at soaked flower foam for 24 hours. The experiment on the hatching of the eggs showed that eggs could be stocked at 16℃ for 10 days with 7 day pre-period after laying, representing 85% hatchability.

아메리카왕거저리의 사육기간을 단축과 기능성 향상을 위해 밀기울에 다양한 먹이를 보조사료로 공급하여 발륙기 간과 무게를 측정한 결과, 먹이종류별 아메리카왕거저리의 발육기간은 조단백질함량이 많은 배합사료와 밀기울에서 80.8일과 75.6일로 가장 짧았으며 버섯배지는 160일이상 소요되었으며 왕겨의 생충율은 85%로 가장 낮아 버섯폐배지 와 왕겨는 먹이원으로 적절하지 않았다. 보조 먹이원 선발을 위해 할맥, 압맥, 배추, 백련초, 파프리카, 개똥쑥을 20~80% 밀기울에 첨가한 결과 압맥과 할맥은 정상적으로 생장하지만 백련초, 개똥쑥 혼합에서는 접종 직후부터 죽은 개체들이 출현하여 생충율이 12.9%, 10.8%로 아주 낮게 나타났으며 배추와 파프리카도 24.2~38.8%로 낮아 보조사료로 적합하지 않았다. 들깨와 콩가루 역시 생충율이 높지 않아 1, 2차 시험결과 할맥, 압맥과 메밀이 보조사료로 적합하였다.

The Small hive beetle, Aethina tumida (Murray, A. 1867) (commonly abbreviated to SHB), is one of notifiable pest in the world. SHB were confirmed in the southeastern United States in 1998 in a apiary in Florida. The SHB also was found in Korea in 2016. The SHB larvae have relatively large heads and numerous protuberances covering their bodies. Upon full maturation, larvae have reached a length of 10 mm. Adult females are length and width of ± 5.5 mm and ± 3.4 mm. Naturally occurring small hive beetles can vary greatly in size, possibly depending on diet, climate, and other environmental factors. Additionally, we were analyzed the mitochondrial cytochrome oxidase I (COI) gene of the SHBs. The sequence of the COI gene of SHB was identical to that of SHBs in Korea, but different by fourteen positions from Italy.

The technique of artificial insemination is the possible one that can surely control mating of the selected drones with the virgin queen. This technique was first time applied with A. cerana in Korean. The average amount of semen can collected from one Korean A. cerana drone was 0.09 μl and 0.1 μl of Vietnamese one, whereas the A. mellifera was more than 6 times (0.58 μl semen per A mellifera drone). Obtaining 1 μL of semen have to collect from 11.94 drones that successful semen ejection. Queens artificially inseminated with 4 μl of semen (once insemination) or 8 μl of semen twice (each insemination with 4 μl of semen) started laying egg later than naturally mated queens 5.3 and 2.5 days, respectively. The onsets of oviposition of artificially inseminated queens were 12.5 to 15.3 days.

Due to their environmental and economical consequences, invasive species have become a major concern worldwide. Among them, the yellow-legged hornet, Vespa velutina, is a keen hunter of domestic honeybees. They use olfactory cues from the prey to assess food information. In this study, we investigated the attraction behavior of V. velutina to honeybee pheromone under outdoor conditions. Nine honeybee pheromones were tested and compared in order to find the best attractant. When testing specific compounds, the honeybee queen pheromone, homovanillyl alcohol, proved highly attractive.

Vespa velutina nigrithorax prey on various insect and especially hunts domestic honeybees, such as the European honeybee, Apis melifera. For that reason, V. velutina predation has a direct economic impact on apiculture. In particular V. velutina queens are able to establish of new colonies, so they are suitable for V. velutina management. This study was conducted to investigate the attractant of V. velutina Queen. Four traps were tested and combined attractant such as honeybee comb extraction, honeybee extraction, pollen, rice wine and sugar syrup for attraction efficacy. We was able to observe V. velutina Queen in late April to May. And Honeybee extraction, rice wine and sugar syrup baits (5 : 3 : 2) was the best combination for trapping queen on spring.

The purpose of this study was to determine anthropometric measurements, dietary nutrient intakes, simple food intake frequencies, and rates of obesity in Cambodian women. A total 186 women, aged 20-69 years, living in Kampong Spue province of Cambodia and having the responsibility to prepare family meals participated in this study. Height and weight were measured body mass index (BMI) was calculated, and one-day 24-hour recall and food frequency questionnaires were conducted. In total, 18.8% were underweight, 49.5% were normal weight, 13.4% were overweight, and 18.3% were obese according to the World Health Organization BMI standard for Asians. No significant difference in height by obesity level was determined (p≥0.05). The mean energy intake was 1571.2 kcal/day and protein intake was 43.6 g/day. There were significant differences in protein, niacin, and vitamin C intakes by obesity level (p<0.05). The prevalence of subjects consuming vitamins and minerals less than 75% of Recommended Dietary Allowances was 73-99%. All Cambodian women consumed rice ≥1 time/day. Approximately 50% of subjects reported ≥1 time/day intake frequency of bread, cookies, and chips. In total, 35% indicated no intake of beans or bean products. For intake frequencies of carbonated beverages and sports drinks, there was a significant difference by obesity level (p<0.05). These results may be very helpful to prepare nutrition education programs for Cambodian women
