| Summary: | Citripestis sagitiferella (Lepidoptera: Pyralidae) was an important cirrus pest in Indonesia causing yield loss up to 50%. The objective of this research was to determine the preference of C. sagitiferella moths to volatile compounds extracted from three citrus varieties (Pacitan sweet orange, Nambangan Pummelo, and mandarin orange).
The fruits for extraction were taken from Batu, Malang (sweet orange and mandarin orange) and Magetan (pummelo) in July 2001. The volatile compounds were obtained by a steam distillation method. The larvae of C. sagitiferella were collected from damaged sweet orange (Batu, Malang) in October 2001, and brought to the laboratory for subsequent development. Newly emerged moths were used in this study. The preference tests were carried out using a Y shape olfactometer. The GC and GC-MS were used to detect the components of volatile compounds.
The results showed that C. sagitiferella moths attracted to volatile compounds extracted from all citrus varieties, with the volatile compounds from sweet orange was found to be the most preferable, followed by pummelo and mandarin orange. Furthermore, the volatile compounds extracted from the six months fruit of sweet orange was more attractive for C. sagitiferella moths then was the two months old orange fruit.
