Abstract

Whitefly Bemisia tabaci Genn. is one of the main pests in vegetables.  Whitefly can cause direct and indirect damage, as a vector of various viruses. Damage caused by whiteflies attack could cause a loss of 20-100%.  These research were done in insect cages at glasshouse with antixenosis mechanisms (free choice test). Host plants were used 4-6 leaves or 6-8 DAP. The genetic material used for experiment with various host plant were chili (Capsicum annum L.) genotype Yuni, Kastilo and Laris, eggplant (Solanum melongena L.) genotype Ratih Ungu, tomato (Solanum lycoperssicon L.) genotype New Mutiara, cucumber (Cucumis sativus L.) genotype Maestro and okra (Abelmoschus schimosus L.) genotype Nayla.  While the genetic material used for chili genotypes were Yuni, Kastilo, Laris, C00265, PBC 495, Ayesha, Ungara, Landung, Cilibangi-2, 12 OP and Bara.  The objective of this study was to evaluate the preference (antixenosis) of B. tabaci on various host plants and Chili genotypes.  The number of eggs and early stage nymphs in the chilli genotype Yuni, Kastilo, Laris were higher in the chilli cropping compared to various host plants.  This indicated that planting with various plants confused whitefly in choosing a host plant.  Cucumber and eggplant were plants that had a higher preference than others.  Therefore that are not recommended for intercropping with chili.  Tomato and okra were alternative plants that can be used in intercropping with chili.
