Sweet corn (Zea mays saccharate) is cultivated in Denpasar, Bali, which is harvested when it is young for daily use, both for vegetables and for consumption, boiled or grilled. Most of the pests found were borers (Ostrinia furnacalis, Crambidae, Lepidoptera), flies (Musa domistica, Muscidae, Diptera), grasshoppers (Locusta sp., Acrididae, Orthoptera) and rats (Rattus rattus, Muridae, Rodentia). The pest diversity index ranged from 0.519-1.003, the pest dominance index ranged from 0.269-0.600 and the evenness index between species ranged from 0.094-0.700. This means that the diversity is very small, supported by a small evenness index, which also means that there are insect pests that dominate. Population dynamics of insect pests range from 0.10 to 0.21, which means the number of births and additions per day per hundred is 10 to 21 individuals. The relationship between pests and weather factors (temperature and humidity) only for borers (located on Jalan Sekarsari) has a significant positive correlation of 0.77* with the regression equation Y = 0.348 X – 24.356 (R2 = 0.71, X = temperature and Y = borer population).
