Gall formation in the fruits of guava (Psidium guineense) Swartz (Myrtaceae) and its relationship with the microhymenopterans Prodecatoma sp (Eurytomidae) and Torymus sp (Torymidae)
Fruit production and fruit gall formation on Psidium guineense were recorded monthly in 1986 at Barba, Costa Rica, and a peak was observed at the end of the wet season. Only 3.8 percent of the fruits had galls. Larvae of Prodecatoma sp. and Torymus sp. were found inside the seeds enclosed in the galls, one larva per seed. The emergence phenology of Prodecatoma sp. coincided with the flowering phenology of the shrub and that of Torymus sp. with the fruit phenology. The data obtained suggest that Prodecatomasp. is the gall maker, while Torymus sp. is probably a parasitoid of the former.
