This work aimed to test the occurrence of types of resistance in cotton varieties (Gossypium hirsutum L.) including non-preference to oviposition and feeding and antibiosis to Alabama argillacea (Hubner, 1818), in laboratory experiments (27±2 ºC, 70±10% de R.H. and photophase of 14 hours). The experiment to evaluate the non-preference for oviposition and feeding in free choice tests used a randomized block design, while the tests without free choice used a completely randomized design. To evaluate antibiosis, leaves of the varieties DeltaOpal, NuOpal, FMT 701, FMX 910 e FMX 996 were fed to the larvae daily. The duration of each insect phase, the larvae mass in the 10th day, the pupa mass with 24 hours, the larva and pupa stage, the adult longevity, total viability and fecundity were recorded. The varieties NuOpal and FMT 701 showed resistance by non-preference for feeding. The varieties NuOpal, FMT 701 and FMX 910 showed resistance by antibiosis to A. argillacea.
