1. 쌀바구미류는 성충>유충>용의 순으로 체내에 곰팡이를 많이 갖고 있었다. 2. 무균소맥에서 사육하면서 체내 균류의 잔존상황을 조사한 바 10일후에는 완전히 제거할 수 있었고, 가장 오래 잔류하는 것은 A. candidus였다. 3. 곰팡이류의 산난수에 미치는 영향은 A. candidus 구가 가장 많았고 A. ruber 그리고 대조구의 순이고 A. niger구가 가장 적었다. 4. 유충의 생육은 A. candidus>A. ruber>대조구의 순으로 양호하였고 A. niger구에서는 2-3령까지 밖에 발육을 하지 못하였다. 5. 생육이 가장 빠른 것은 A. candidus구로 제3주에용화개체를 볼 수 있었고 제4편에 성충 우화를 볼 수 있었다. 대조구에서도 동일한 경향을 볼 수 있었으나 생육은 약간 늦었다. 6. A. niger구에서 생육이 불량한 것은 왕성한 균생장으로 쌀바구미의 활동이 저해되는 것과 동시에 불명의 원인이 있는 듯 하였다. 7. 저곡중의 쌀바구미와 곰팡이류간에는 진화과정을 통하여 원시적 협동작용이 있었다.

A study was conducted to investigate the relationships between the rice weevil and associated storage molds. The results are as follows; 1. All of the developmental stages of the rice weevils are carrying some storage molds in their bodies, and the order of magnitute in the number was the adult, larva and pupa. 2. The molds persist in the body of the rice weevil for 10 days who.1 they were fed on the mold free wheat, and the most persistant mold species was A. candidus. 3. When the mold free weevils were reared on the pure culture of the molds on the wheat, the number of eggs laid by the Lveevil were the greatest for A. candidus. following A. ruber, and the . least number Lvere obtained with A. niger 4. The rice weevil could complete in the pure mold culture on the wheat except for A. niger where the larvae had developed by 2nd or 3rd instars. 3. The shortest developmental periods was obtained with A. candidus and the first adult emerged in 4th week. 6. The unfavorable effects of A. niger on the development of the rice weevil might be associated with the fast growth of the mold together with some unknown effects. 7. There seems to be a protocooperative interaction between these two oraganisms having been developed through the long evolutionary course in common habitat.
