Abstract

Host suitability and the preference of Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae) on different host plants. Potato leafminer, Liriomyza huidobrensis has become a major pest on highland vegetables since its invasion in Indonesia in 1994.  The objectives of  this research  was  to  elucidate  the  level  of  suitability  and   the   preference  of  L. huidobrensis on different host plant species. Research was conducted  in Insect Ecology Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture-IPB. The result of laboratory experiments indicated that host plants showing the highest level of suitability (based on the intrinsic rate of increase, r) were potato (Solanum tuberosum), chinese cabbage (Brassica chinensis var. parachinensis), kacang endul (P. vulgaris), and snap bean (P. vulgaris).   Low host suitability were found on cucumber (Cucumis sativus), tomato ( S. lycopersicum), wild radish (Nasturtium indicum) and a non-crop vegetation, galinggang (Galinsoga parviflora).  There was consistency between suitability and host preference. The first four host plants mentioned above were preferred for feeding and laying eggs.
