Jatropha curcas (Jatropha curcas L) is one of the plantations that is produce vegetable oil which has the potential to source biofuels. The low productivity and its content is a problem that is faced by Jatropha plant is Indonesia. The cause of low productivity is the potential production of the varieties used, pest disorders, and the limited availability of water. Attacks of various pests and diseases on Jatropha plant that cause damage ranging from mild to severe, so the character of resistance to pests or diseases is needed (Singh et al., 2006).
This study aims to obtain data or information related to the resistance of some Jatropha plant genotypes against white lice pests (Ferrisia virgata .C). The treatments used in this study were some Jatropha plant with numbers 5.1.4, 7.1.18, 18.1.14, IP-3A, and IP-3P. This study uses a Completely Randomized Design with different tests in field activities, while in laboratory activities using a Completely Randomized Design with 4 replications then analyzed with a 5% BNJ test.
Observation parameters of the spread of white lice in the form of eggs, nymphs and imago, the results of the spread of the eggs’ number, nymphs and imago of white jatropha plant in the comparison genotype ie IP-3P and IP-3A genotype were significantly different compared to the distance of the tested Jatropha plant ie genotyping numbers 5.1.4, 7.1.18, and 18.1.14 after a 5% BNJ test was performed. Jatropha agronomic parameters include the percentage of crop damage, plant height, stem diameter, number of leaves, number of branch tips, number of primary branches and secondary branches, number of fruits, number of seeds and weight number of dry seeds, the test results are not significantly different (ns), except the number of fruits, number of seeds and dry weight of seeds look significantly different (**) in the comparison genotype IP-3P has more number of fruits than other genotypes namely genotype numbers 5.1.4, 7.1.18, 18.1.14, and IP-3A , after doing a 5% BNJ test.}
