Abstract:
There are seven pests found in the corn plantations in Sanur, among others: house fly (Musa domestica) Diptera, grasshopper (Dissosteiracarolina) Caelifera, kumbang (Orystes rhinoceros) Celeoptera, caterpillar (Spodoptera litura) Coleoptera, caterpillar (Helicoverpaarmigera) Lepidoptera, walangsangit (Leptocorisaaratorius) Hemiptera, and white tick (Trialeurodesvaparariorum) Homoptera. Natural enemies found during the research were: army beetles (Chauliognathuslugubris) Coleoptera, army dragonflies (Dunia odonatan) Odonata, wasps (Apisdorsata) Hymenoptera, and red dragonflies (Oryhetrumsabina) Odonata. The highest pest prevalence was obtained from house flies with a value of 21.08%, while there was a natural enemy obtained from red dragonflies with a value of 31.75%. The diversity index of pests was obtained 3.2099 with a dominance index of 0.8479, while the index of diversity of natural enemies was obtained 2.2956 with a dominance index of 0.7417. The linear regression relationship between house flies and cobworms with temperature had a significant effect, while the regression relationship between stinky bugs, and temperature had a very significant effect. The regression relationship between house fly and humidity had a significant effect, the beetle with humidity was very real, and the stink bugs with humidity had a very significant effect, while the multiple regression relationship between stink bugs with temperature and humidity had a very significant effect. The regression relationship between natural enemies (army dragonflies) and temperature shows a very real effect
