Intercropping patterns effect of cardamom and cayenne pepper on population and intensity of whitefly pest’s attacks (Bemisia tabaci)

Abstract

The study aimed to determine the population and intensity of attacks caused by whitefly pests on intercropping and monoculture cultivation areas. This research was conducted from June to August 2021 in Pace Village, Silo District, Jember Regency. The method used is to compare two intercropping and monoculture cultivation areas of medicinal plants cardamom - cayenne pepper. The first plot was cultivated in monoculture with pest control using an insecticide with the active ingredient Alfametrin 15 EC, while in the second plot, cayenne pepper - cardamom intercropped cultivation with a spacing of 1x2 meters and pest control without pesticides. A systematic random sampling of 50 plants in both cropping patterns on cultivated land. Observation of pest populations using insect nets, pitfall traps, and insect suction in the field. The data were analyzed using SPSS version 15.0. The data were tested for normality using Kosmorogrof Smirnov with non-parametric analysis. The results showed that the whitefly population in monoculture cayenne pepper cultivation had a higher average of 57.58 individuals, while in cayenne-cardamom intercropping cultivation, the population average was 51.00 and showed significantly different results. The intensity of whitefly attack showed significantly different results in monoculture cultivation of 45.58% while intercropping pattern of 50.10%.
