Abstract
The distribution and life history or the mango weevil, Cryptorhynchus mangiferae (Fabricius) (Coleoptera: Curculionidae), was studied in Hawaii. The weevil was round on all major islands, but its distribution was not related to location on island, host plant density, cultivar, or other environmental parameters. Populations were sampled in a mango orchard at biweekly intervals during the fruiting season. No differences were found in infestation rates among fruit in different vertical zones in the canopy. Head capsule width data suggested that there were more than five larval instars. Young larvae were first collected in mid-April while pupae and adults were (list found at the end of May. More than one weevil can successfully develop in a seed. In the field, adults appeared to randomly select opposition sites.
