An ecological study on the sugarcane moth borers, Chilo infuscatellus snellen, Chilo sacchariphagus (Bojor) and Sesamia inferens (Walker), was carried out in the laboratory and supplemented with investigation under field condition at Nakhon Pathom, Thailand. The investigations included various aspects on population biology, ecology and population dynamics of the moth borers and the natural enemies associated with them. Biological and partial ecological life tables of the moth borers were constructed. Several methods of population analyses were used to analyse the populations of sugarcane moth borers and to detect their distribution patterns, age distribution, and factors regulating the borer populations. The survey and evaluation of natural enemies revealed that Trichogramma chilotraeae Nagaraja - Nagarkatti, Apanteles flavipes (Cameron) and Tetrastichus sp. were the most important egg-, larval-, and pupal parasites of sugarcane moth borers, respectively. Other less important natural enemies included some species of hymenopterous parasites, Telenomus sp., an unidentified braconid in Subfamily Doryctinae, Temelucha philippinensis (Ashmead), Xanthopimpla sp., a species of tachinid, some species of earwigs, and some species of spiders. These natural enemies were important regulating factors on the populations of sugarcane moth borers
