Karakteristik Semen Ngengat Attacus atlas (Lepidoptera: Saturniidae)

Abstract

This research aimed to study the characteristic of A. atlas moth semen and spermatozoa. Semen were collected from ten imagos by using microtube. Immediatly after collection the semen were evaluated macro- and microscopycally. Result showed that A. atlas had a variation on the semen volume range from 0.03-1.45 ml/ejaculate with the average of 0.42±0.47 ml. The semen pH was normal with the average 6.49±0.07 range from 6.20 to 7.00. Semen density moderate to thick with a variation of semen color ranging from white, yellowish to brownish and soil in odor. Microscopic evaluation showed that the sperm motility was very good (80-90 %) with average of sperm concentration 318.50±206.61x106/ml, ranging from 60-635x106/ml. The sperm shape was round and small only 1 μm in diameter.
