ABSTRACT
Bactrocera flies are noxious pests of fruits mainly infecting guava and mango in Sindh. Bactrocera zonata and Bactrocera dorsalis are the deleterious pests of several plant species. Trybliographa daci (Weld.) and Diachasmimorpha longicaudata (Ashmead) are natural enemies of fruit flies widely used as bio-agents in biological control programs against Bactrocera species. In current investigations we inspected the infected guava and mango fruits from lower (Hyderabad) and upper (Larkana) Sindh regions for population surveillance of parasitoids during 2019. The results shown (P<0.05) maximum number of Trybliographa daci were (55.60±4.52, 46.40±5.47) obtained from guava infested fruits of both regions. Moreover, Maximum number of Bactrocera zonata were emerged from infected guava (381.00±10.85, 259.40±16.95) collected from lower and upper regions of Sindh. The current studies recognised that larval cum pupal parasitoid Trybliographa daci could be effective in controlling population of Bactrocera spp. in orchard agro-ecosystem of Sindh region.
