Effect of Concentration of Entomopathogenic Nematodes (Steinernema spp.) to Bemisia tabaci Genn. (Hemiptera; Aleyrodidae) On Red Chili Plants

Bemisia tabaci is an important pest on red chili plants. The entomopathogenic nematodes Steinernema spp. has the potential to control insect populations. purpose of this study was obtain concentration most effective in controlling B. experiment conducted at Greenhouse, Faculty Agriculture, Universitas Padjadjaran, Jatinangor, from January September 2020. used experimental methods in-vitro and in-vivo. a completely randomized design observe mortality tabaci. in-vivo Randomized Block Design population consisted seven treatments four replications. of: (without spp.), 50, 100, 150, 200, 250, 300 IJ/ml (IJ = third infective juvenile). Each treatment infested with 20 second nymphs using plants 30 days after planting. results showed that nematode IJ/ml, causing Tabaci 100 can suppress chilli plant lower level 12 application.
