Abstract

In Chile, Aonidiella aurantii has emerged as a significant pest of citrus crops, due to increasing population levels and the cosmetic damage it causes to fruits.
Active ingredients traditionally employed for pest control in citrus have become restricted, elevating the A. aurantii relevance in phytosanitary management programs across some orchards.
From autumn 2020 to autumn 2023, we examined its seasonal cycle, the average onset of male flights, the peak period for migratory nymphs, and the natural abundance of the parasitoid Aphytis melinus in both commercial and domestic lemon orchards.
Our results indicate that male flights typically begin around September 24 (±4 days), with the peak of crawlers occurring 43±10 days after this event.
Three generations were observed, corresponding to spring, summer and autumn.
This information supports the sustainable management of this pest.
