Description
Summary:The papaya borer weevil, Pseudopiazurus papayanus (Marshall), is generally considered a secondary pest, but it has been reported in high infestations in Northeast Brazil. This work aimed at evaluating the occurrence of P. papayanus and reporting its infestation level in papaya genotypes kept at the germplasm bank of Embrapa Cassava & Tropical Fruits (Cruz das Almas, Bahia, Brazil). The number of larvae, pupae and adults found in each plant of 65 Carica spp. genotypes and of three Vasconcella spp. genotypes was registered in three to five plants of each genotype, by cutting the exsudating trunks lenghtwise. Papaya borer weevil was found in C. papaya and V. cauliflora but not in those of V. quercifolia. Among the evaluated genotypes, 52.4% of those belonging to the Solo group were infested, against 25.0% of the Formosa group. Larval infestation was the best criterion for sorting out genotypes concerning this insect infestation. This is also the first occurrence of the papaya borer weevil on V. cauliflora.
