The objective of this study was to evaluate the attractiveness and food consumption of Opsiphanes invirae by folioles of different genotypes of palm oil. Choice and no-choice tests were performed using newly hatchet larvae of O. invirae aged 12 days. Five genotypes were used, such as Deli × LaMe, Compact × Ekona, Deli × Ekona, Compact × Nigeria, and Compact × Ghana, planted in 2008. In the choice test, the preferred genotypes were Compact × Ekona at 3, 5 and 30 minutes with insects size 1.70, 2.20, and 0.60, respectively, and the Compact × Ghana at 48 and 72 hours with insects sized 0.80 and 1.10, after the release of the caterpillars, while the Compact × Nigeria was the less attractive and less consumed in both tests with newly-hatched larvae. In the tests with caterpillars aged 12 days, no difference was found for attractiveness. In the no-choice test, the Deli × LaMe treatment was the least consumed genotype, the Compact × Ghana, although little attractive, was the most consumed in the choice and no-choice tests. The genotype Compact × Nigeria showed non-preference resistance for supply with newly hatched caterpillars of O. invirae.
