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.
Highlights
The fruit fly Bactrocera spp. is the main pest after thrips on red chili plants, which reduced plant productivity by 30-60% [1]
The fruit will change color to yellowish-red, and when viewed from the inside, there is a larvae of Bactrocera spp
Red chilies were attacked by Bactrocera spp. result in the fruit not being harvested because it will be fall out before it can be harvested
Summary
The fruit fly Bactrocera spp. is the main pest after thrips on red chili plants, which reduced plant productivity by 30-60% [1]. The larvae of Bactrocera spp. shows no symptoms, looks healthy and intact from the outside. The fruit will change color to yellowish-red, and when viewed from the inside, there is a larvae of Bactrocera spp. Red chilies were attacked by Bactrocera spp. result in the fruit not being harvested because it will be fall out before it can be harvested. Bactrocera spp. was included in the quarantine pest to watch out for and become one of the obstacles in chilies production [2]. The technique for controlling Bactrocera spp. has been done by control using synthetic pesticides. The application of insecticides in controlling fruit fly pests is not effective because the larval phase is in the fruit tissue
