The infesting species and their infestation indices of fruit flies were determined for eleven guava genotypes (Psidium guajava L.). From March to April 2000, ten mature fruits of each genotype were harvested at weekly intervals from insecticide unsprayed trees located in the municipality of Monte Alegre do Sul, SP, Brazil. Fruits were brought to the laboratory, weighed and placed in individual ...

This study aimed to identify parasitoid species of frugivorous larvae and to describe the tritrophic interactions involving wild fruits, frugivorous insects and their natural enemies at Adolpho Ducke Forest Reserve (RFAD) (Manaus, AM, Brazil). Collections were performed in four 1 km2 quadrants in the corners of the RFAD. The wild fruits were collected inside the forest in access trails leading ...

The species of Ademon Haliday (Braconidae, Opiiinae) from China are studied. Two new species are described: A. lechrilophodes sp. nov. and A. xuthus sp. nov., and a key to the identification of Old World Ademon is provided.

Understanding and predicting potential competitive outcomes is critical in the design of biological control programs when considering multiple agent introductions. Tephritid fruit flies (Diptera: Tephritidae) include some most destructive pests vegetable crops worldwide. Parasitoid guilds fruit-infesting tephritids are dominated by opiines (Hymenoptera: Braconidae: Opiinae) that have been main ...
