본 연구는 우수한 꿀벌 신품종 육성을 위해 국립농업과학원에서 육성된 재래꿀벌 RX계통을 분양받아 ’23~’24 년까지 부안군 변산면에 위치한 전북농업기술원 잠사곤충시험장 양봉사에서 꿀벌세력, 수밀력, 질병저항성, 온순성, 질병발생, 월동능력을 한라벌 품종과 비교하여 조사하였다. 8~11월 RX계통의 꿀벌세력 감소는 3.9%로 한라벌 39.8% 대비 상대적으로 낮았고, 수밀력, 청소능력, 온순성은 유의적 차이가 없었다. 낭충봉아부패병 등 질병은 전북동물위생시험소에서 병성검정한 결과, 두 시험군 모두 항원이 검출되었으나 임상증상은 없었다. 그리고 월동 중 한라벌 품종은 폐사한 반면, RX계통은 모든 시험군이 월동에 성공하였고, 또한 월동전·후 먹이감 소량이 적어 월동능력이 우수한 것으로 판단하였다. 본 연구는 국립농업과학원 공동연구사업(PJ01504205)의 지원을 받아 수행하였다.

The growth characteristics according to temperature conditions were investigated in the breeding room of the Sericulture & Entomology Experiment Station for Oriental garden crickets(Teleogryllus emma Ohmachi et Matsuura) and Modeagali-crickests(Loxoblemmus doenitzi Stein) collected from the lawns of Byeonsan-myeon, Buan-gun, Jeollabuk-do. The temperature conditions were 6 treatments from 15°C to 40°C at 5°C intervals using a multi-incubator, and the development period and mortality rate by age were compared using the 28°C breeding room conditions as a control. For T. emma, the higher the temperature, the shorter the total development period was, and the same trend was observed for the growth period by age stage. However, at low temperatures of 15°C and 20°C, all died after the third instar, and at high temperatures above 35°C, all died during development. At 25°C and 30°C, they developed normally, and the mortality rate was about 25%. The L. doenizi had the same tendency as the T. emma, with the higher the temperature, the shorter the development period. The total development period was 57.7 days at 25°C, which was similar to the T. emma's 55.9 days, and the mortality rate was the lowest at 44% at 25°C.

The Black pine bast scale, Matsucoccus thunbergianae is one of the most serious in black pine, Pinus thunbergii forests in Korea. Since this pest was first reported in Goheung, Korea in 1963, which is gradually spread into neighboring regions and now occurs in many regions of the southern and eastern part of the Korean peninsula. The monitoring for distribution of M. thunbergianae was able to observed by naked eye egg sacs and pupa of male on the host until now. Therefore, this monitoring was very difficult in the low density of M. thubergianae. This experiment was conducted to use simple and practical moving cross-shaped flat trap for monitoring of M. thunbergianae. The monitoring of M. thunbergianae using the device was carried out to southern regions of the Korean peninsula. The first emergence of male showed mid. March in Namhae and late march in Busan, Jinju and Pohang. The peak of emergence showed late March in Namhae and early April in the other regions. When the number of M. thunbergianae intermediate nymph showed 58~59, 11~44 and 8~25 on 39.25 ㎠ bark area of the black pine, Pinus thubergii for 1 week, the number of captured its male adult was 58~83, 67~488 and 1~55 on the moving cross-shaped flat trap (10× 13㎝), respectively. The low density of M. thunbergianae was some few the number of capture, but there were no significant difference in its high density. Also, the number of captured its male adult was no significant in the different color (yellow, red, white and blue) of the moving cross-shaped flat trap.
