摘要

利用電子顯微鏡觀察東方果實蠅（Bactrocera dorsalis Hendel）複眼中央背側視細胞之桿小體微絨毛方向旋轉，結果可知依旋轉方向分為兩群：R1-3及R4-6；兩者旋轉方向互成鏡象。依其旋轉的程度可分為三種region；region I：位於個眼角錐體以下約0-84±5μm處，其旋轉率為0.226-0.464°/μm，region II：位於角錐體以下約84-110±5μm處，微絨毛旋轉率約在1.606-5.28°/μm之間，region III：位於角錐體以下約110-160±5μm，旋轉率約在0.09-0.659°/μm。

The rhabdomeres of retinular cells (R1 - 6) in the medial-dorsal region of the compound eye of Bactrocera dorsalis Hendel twist along their length were examined by electronmicroscopy. The 2 groups of rhabdomeres, R1 - 3 and R4 - 6, twist in mirror-image directions. The twisting degree of microvilli of the rhabdomeres could be divided into three regions; region I: it was located at about 0 - 84 ± 5μm below the crystalline cone, their twisting rate were between 0.226 - 0.464° /μm, region II: about 84 - 110 ± 5μm below crystalline cone, twisting rate between 1.606 - 5.28°μm, region III: about 110 - 160 ± 5μm, twisting rate between 0.09 - 0.659° /um.
