Nematode parasite,Auchenacantha spp of flying lemur,Cynocephalus variegatus(Audebert,1799) from Indonesia:Morphological study with SEM

Objective:To observe morphology of Auchenacantha galeopteri(A.galeopteri),Auchenacantha spinosa(A.spinosa) and Auchenacantha parva(A.parva) from Sukabumi and Ujung Kulon, Indonesia using scanning electron microscopy(SEM).Methods:Specimens for light microscopy examination were fixed with warm 70%alcohol,cleared and mounted in lactophenol for wet mounting.Drawings were made with the aid of a drawing tube attached to a Nikon compound microscope.Specimens for SEM examination were processed according to Bozzola.Measurements were given in micrometers(μ m) as the average of findings,followed by the range in parentheses, unless otherwise stated.Results:The measurements of Auchenacantha spp are same with those of previously described.The striatums of male and female A.galeopteri are widen towards outside and wavy.The mouth of female with 6 lips,each of them is wider at base than distal end in A.galeopteri and rectangular in A.spinosa.Both species have dentiform protrusion from inner surface of lips,such structure absent in A.parva,but the lips with transverse festoon like pattern at anterior end of each lip.Conclusions:Using SEM,the lip and the striation pattern of three species of Auchenacantha can be clearly distinguished.Sukabumi and Ujung Kulon are new locality of A.galeopteri and A.spinosa,and A.parva is the new record in Indonesia.

二十八种印度尼西亚木材对白蚁的抗性

我们进行了二十八种印度尼西亚木材对白蚁抗性的比较研究。研究中使用的试验样品大小为5×10×20mm,使用的白蚁是堆砂白蚁Cryptotermes Cyn-ocephalus和大家白蚁Coptotermes curvignathus在聚类分析的基础上推导出抗性的级别。实验结果表明:黄豆树Albizzia procera、印度黄檀Dalbergia latifolia婆罗洲铁木Eusideroxylon zwagerri、柚木Tectona grandis和印茄Intsia bijuga等对两种白蚁都有抗性。楹树Albizzia chinensis和波罗蜜Artocarpus integer仅对堆砂白蚁具抗性,而对大家白蚁则归入抗性与中度抗性间。其余种类的木材归入中度抗性、敏感和极敏感级。
