Abstract

Conservation of natural enemies on maize can be done by utilizing grass weeds as Beetle banks. Natural enemies of shelter and get food from the weed grasses that are in the land irrigated corn. Natural enemies observed in this research were the predator of ground arthropods in the form of ground beetles, tomcat, and predators arthropods in other lands. The trap used is the Pitfall trap. The percentage of arthropod predators was 69%, and arthropods herbivore was 31%. The abundance of soil arthropods in the treatment of weeds grass is higher than the control treatment It is because of the treatment of weed grass soil arthropods get habitat for a place to stay. Weed grasses provide food sources for the arthropods and get protection from an environment that is less supportive. The use of weed grasses in addition to Beetle banks also serves as a place to breed. The highest abundance of arthropods was situated on the treatment Eleusine indica that has a lush lawn and has a characteristic odor favored by arthropods. Arthropods that acts as a predator in the land are the family of Formicidae, Philodromidae, Carabidae, Staphylinidae, Pentatomidae. Some Arthropods from the Pentomidae family have a role as a pest and others as natural predators or predators. Arthropods found in the research was an arthropod that had a role as natural enemies or predator. The Pentomidae family that has a position as a predator is Picromerus Bidens. Ground beetles were found in the C. fossor and Pheropsophus sp. Ground beetles are dominant picking weeds Setaria sp. and Eleusine indica as habitat and place in search of food and life's survival. Keywords: Beetle bank, soil arthropods, weeds.

Abstract

The fruit fly Bactrocera spp. is the main pest other than Thrips in red chilies, which can reduce plant productivity by 30-60%, so that a specific method of handling this pest is needed. This study examines the application of conventional and Integrated Pest Management (IPM) strategies to fruit fly populations in red chili cultivation (Capsicum annuum). Observation of fruit fly population used the comparative method with methyl eugenol traps and incubation of infected fruit. Determination of the research sample based on purposive sampling method and analyzed using descriptive analysis. The test parameters were the fruit fly population indicated by the host's density and hosts' availability in the applied IPM and conventional treatments. The results showed that the fruit fly species encountered were dominated by B. dorsalis with a percentage of 98.18% and B. carambola 1.82%. The fruit fly population's fluctuation in IPM and conventional treatments were significantly different, as evidenced by a one-way variance test at a significance level of 99%. The population of fruit flies in the IPM concept was 547 flies, while the conventional concept was 1546 flies. The percentage of fruit fly population in red chili plants with IPM treatment was 48% smaller than conventional treatments.Keywords: Bactrocera spp., IPM, Population, Red chilies.
