| Abstract: | Maize (Zea mays L.) is very good to human life or as animal feed. In Indonesia, maize is a second commodity as food-producing carbohydrates after rice. Peoples demand for maize increases from year to year. The increase population in Indonesia and compliance program in community nutrition through food diversification drive for increasing demand for corn. In addition, there is increase demand for corn oil, corn meal for livestock feed and corn seed. Maize yield losses due to pest attacks in Indonesia ranged between 25-30% of the plant population every year. Yield loss was caused mainly by the attack of some kind of major pests, such as stem borer (Ostrinia furnacalis), cob corn borer (Heliothis armigera), leaf eaters (Mytimna separata, Valanga nigricooornis, Spodoptera litura) and caterpillars of land (Agrothis ipsilon). The purpose of this study was to determine the major pest species and populations as well as the damage intensity caused in Waeheru village, Ambon Baguala District. This study uses a survey method, where the farmers as samples were determined by purposive, farmers who mainly cultivate corn. Ten plant samples are determined from each farmer randomly. Types of pests found attacking corn plant in Waiheru village, Baguala District, the city of Ambon is: Valanga nigricornis grasshoppers and stem borers (Osterinia furnacalis). Other pests such as Spodoptera litura, Agrothis ipsilon, Mytima separata were not found. The intensity of leaf damage caused by Valanga nigricornis in Waiheru village ranged from 4.17% to 28.40%, with an average of 19.06% has been classified as minor criteria. Population of Ostrinia furnacalis larvae ranged from 1-3 insects per stem (an average of 1.08 insects per stem) with the average of damage intensity of 10.47%, classified as minor criteria. |
