Daftar Isi:
- The control of Spodoptera exigua Hubner (Lepidoptera: noctuidae) is usually done in several ways. Some of them are mass trapping, mating disruptions, and populations monitoring (by using sex pheromones and virgin female beet armyworm moths as lure). The virgin females (that is used for mass trapping or population monitoring) have to be provided by mass rearing. Therefore, a research about content of females beet armyworm sex pheromone that were reared through natural and artificial diet is an important task to be done. Hence we could figure out whether the concentration and composition of sex pheromone which were reared with artificial and natural diet are similar or different. The GCMS analysis of sex pheromone gland extracts from females which were reared with natural diet indicated a sex pheromone compound, tetradecane-1-ol (0.23%). This gland extract also indicated the presence of hexadecane (14.31%), heptadecane (0.42%), nonadecane (1.09%), and betacaryophyllene (1.37%). In the other side, the females which were reared by artificial diet, indicated the presence of tridecanol (3.39%), hexadecane (8.52%), nonadecane (0,23%), and trans-caryophyllene (3.11%), there is no pheromone compound in this extract. the cross-breeding test showed that both types of moths could do mating. The field trapping test showed that both extracts were attractive to males.
