一.利用電子顯微鏡的方法研究東方果實蠅(Dacus dorsalis Hendel)右複
眼中央背側視細胞之桿小體微絨毛具有方向旋轉的特性, 結果依旋轉方向
可分為兩群: R1-3, R4-6, 兩者旋轉形式互成鏡像相反方向旋轉。依其旋
轉的程度可分為三個region, 即(1)region Ⅰ: 位於個眼角錐體以下約0-
84±5μｍ, 其旋轉程度非常小, 旋轉率約為0.226-0.464°/μｍ。(2)
region Ⅱ: 位於角錐體以下約為84-110±5μｍ, 微絨毛旋轉率約在1.60
2-5.28°/μｍ之間, 為旋轉率最大之區域, 且此區為R7與R8接替之處。(
3)region Ⅲ: 位於角錐體以下約110-160±5μｍ, 此區旋轉程度非常小,
旋轉率在0.09-0.659°/μｍ之間。
二. 利用胞內記錄法測得東方果實蠅右複眼中央背側視細胞之光譜感光曲
線, 最高吸收光波在紫外光部份(λmax=349nm),其次在青綠光部份(λmax
=460nm)。而相對於此光譜感光曲線其偏光感光反應之偏光感光值約為1.1
-1.4, 且其偏光感光曲線依θmax可分三種型態, 即(1)θmax=3.83°。(2
)θmax=152.53°。(3)θmax=48.19°。

1.Electro-microscopic examination showed that the rhabdomeres of
retinular cells (R1-6)in the medial-dorsal region of the left
compound eye of Dacus dorsalis Hendel twist along their length.
Again as in Musca and Calliphora, the two groups of rhabdomeres,
R1-3 and R4-6, twist in mirror-image directions. As the twisting
degree was concerned, the rhabdomeres could be divided into
three regions; (1)region Ⅰabout 0-84±5μｍ below the
crystalline cone, twisting rate between 0.226-0.464°/μｍ.(2)
region Ⅱ: about 84-110±5μｍ, twisting rate between 1.602-5.28
°/μｍ.(3)region Ⅲ:about 110-160±5μｍ, twisting rate between
0.09--.659°/μｍ.
2.Intracellular recordings were made from the medial-dorsal
region of the Dacus dorsalis Hendel. Spectral sensitivity curve
showed that the maximun absorbing band is near the UV band (λ
max=349nm), and the second is near the green band (λmax=460nm).
Polarization sensitivity values averaged 1.1-1.4. Divided by
polarization sensitivity θmax, they had three pattern:(1)θmax
=3.83°;(2)θmax=152.53°;(3)θmax=48.19°。
