Methods for identification of Anastrepha larvae (Diptera: Tephritidae), and key to 13 species.
Detailed methods are provided for observing useful characters to distinguish among species of Anastrepha in their immature stages. Additionally, a key is provided to 3rd-instar larvae of 13 species including A. bistrigata, A. distincta, A. fraterculus, A. grandis, A. leptozona, A. ludens, A. obliqua, A. pallens [Pseudodacus pallens], A. serpentina, A. striata and A. suspensa. There is considerable overlap in many character states among species. Discriminant analysis is necessary to distinguish among species in some couplets.
