Closterocerus coffeellae (Hymenoptera: Eulophidae) is a parasitoid of the coffee leaf miner occurring in farms with high selection pressure caused by pesticides and different landscape patterns on surrounding crops. This work aims to detect morphometric variations levels Fluctuating Asymmetry (FA) wings C. history insecticide use composition Planalto region, Bahia, Brazil. Parasitoids originated from six this region. We prepared microscopy slides right 30 females each population. determined wing size shape geometric morphometry analysis, adding 1 landmark 9 semi-anatomical landmarks wings. The metrics (3 km radius) spatial dependence for AF were calculated using geostatistical analysis. Higher forest cover edge density plantations lead an increase reduced FA levels. Diversity agricultural land pesticide reduces increases farms. centroid exhibited strong moderate aggregation across conservation recommended since species can be used as bioproduct against miner, biocontrol solution Furthermore, adopting conservative practices natural vegetation essential parasitoids. It must included management, mainly higher cropland diversity use.
