초록

태국은 1980년대 중반 낭충봉아부패병을 경험하고이로인하여 약 90% 이상의 봉군이 폐사하는 등 최근국내에서 겪고 있는 낭충봉아부패병의 증세를 이미극복한 나라로써 이러한 태국의 경우 낭충봉아부패병 인공감염을 통한 낭충봉아부패병 저항성 계통을 선발하는 시험을 수행하였다. 그 결과 약 5세대동안양성된 계통이 낭충봉아부패병에 대한 저항성이 있는 것으로 확인하였다. 따라서 이러한 시험기법의 국내 도입 시험을 통한 국내 토종벌 낭충봉아부패병 저항성 계통 선발 육성으로 낭충봉아부패병으로 인한봉군폐사를 극복하고 그 결과 토종벌 사육농가의 경영 안정성에 기여할 수 있을 것으로 기대된다.

영어초록

Sacbrood virus (SBV) is an important disease of larval Asian honey bee (A. cerana). To study thesusceptibility of A. cerana larvae to SBV, various doses of Sacbrood virus sugar syrup were fed toadult A. cerana food and disease development was monitored. A. cerana colonies, surviving from ThaiSacbrood virus disease, showed disease symptoms earlier, with more severity and with a graterreduction in prolificness in parent than in daughter, colonies. Studies made on the larval susceptibility,symptomatology and sequence of changes observed in the affected colony revealed that all the fourlarval instars of A. cerana indica F., were susceptible to TSBV. In the present investigation, recoveryfrom infection was observed within 30 day after the appearance of disease in the colonies. Parentcolonies took longer to recover from infection than daughter colonies. Similarly, percentage reductionin prolificness in the virus-fed colonies decreased from 40 to 7% from parent to 5th generation, ascompared to respective colonies before feeding. TSBV can bee controlled by biotechnical methodeither by requeening an infected colony with a virgin queen or queen cell, or by caging the queen ofdn infected colony for 7~8 days.
