Insect-Plant Interactions and Control

Collections of wild and cultivated tropical fruits were examined for infestation by Anastrepha spp. and Ceratitis capitata (Wiedemann) (Diptera: Tephritidae). Of 440 collections (with at least 4 fruits in each) from 201 sites throughout Costa Rica, Central America, 95% of the fruit flies (n = 4126) belonged to the genera Anastrepha (A. obliqua, A. striata, A. serpentina, A. manihoti, A. pickeli, A. distincta, A. chiclayae, and A. fraterculus), while 4.7% were C. capitata. Anastrepha spp. had a strong preference for host plants within the same family. A. obliqua infested 92% of the attacked Mangifera indica (mango), 87.5% of the Spondias mombin (jobo), and 100% of the S. dulcis (June plum/golden plum) and S. purpurea (Spanish plum) collections, all Anacardiaceae. A. striata was recovered from 97.8% of the infested Psidium guajava (common guava), 97% of the P. friedrichsthalianum (Costa Rican sour guava) and 100% of the P. savanarum (guisaro) collections; these three host species belong to the Myrtaceae. A. serpentina was the dominant species in Sapotaceae host plants, and it was recovered from 100% of all infested Manilkara achras (zapote), and Pouteria cainito (yellow caimito), and 98% of Chrysophyllum cainito (caimito morado). A. manihoti and A. pickeli were associated with Manihot esculenta (cassava) (45.8% and 54.2% infestation, respectively). A. chiclayae infested 100% of the Passiflora quadrangularis (granada) collections. A. distincta infested species of Inga (Fabaceae) exclusively. C. capitata was the only species of fruit fly recovered from Prunus persica (cling peach). The infestation rates for C. capitata were low (<7%). Annual phenology of the above listed host plants is presented with additional observations on interactions between fruit flies and their host plants.
