Resumo |
Cotton genotypes resistance to Alabama argillacea (Huebner, 1818) due to antibiosis has been evaluated in laboratory trials (at 27 ± 2°C, 70 ± 10% relative humidity and 14 hours photoperiod). Six different genetic materials (T 1122-13-1, STO 285 N, JPM 157, T 953-13-4-2, CNPA 9211-21, and CNPA 9211-31) have been tested in a completely randomized experimental design, with ten replications, each one with ten larvae/genotype. Larvae have been supplied with leaves daily. The following variables have been scored: time length of several insect stages (from larvae to adult), average mass of larvae and pupae as well as average larval, pre-pupal and pupal mortality rates. All genotypes have revealed longer overall average time length of stage duration from larvae to adult, as compared to STO 285 N; however, CNPA 9211-31 and CNPA 9211-21 have shown the smallest average mass of pupae along with high frequencies of pre-pupae and larvae to adult mortalities. The results strongly suggest that antibiosis is one of the resistance mechanisms to A. argillacea in that two cotton genotypes. |
