BAYARDO CAMBERO, G.S. et al. Identification and biorational management of thrips (Vaccinium corymbosum L.) in Nayarit, Mexico. Revista bio ciencias [online]. 2023, vol.10, e1490.  Epub 23-Feb-2024. ISSN 2007-3380.  https://doi.org/10.15741/revbio.10.e1490.

This research aimed to morphologically identify the thrips associated with blueberry cultivation in the municipalities of Xalisco and Tepic, Nayarit; Also, biorational insecticides were evaluated for their management. During 2022, thrips were captured directly in the crop with the knockdown technique. Insecticides were applied with 5 L manual sprayers, 8-lb pressure, and a full cone nozzle extension. Five applications were made at 15 days intervals. In Xalisco, eight species of thrips were recorded, while in Tepic only Scirtothrips dorsalis was registered, which predominated in both properties. Formulated products based on cinnamon extract, garlic, azadirachtin, mustard, a regional control Spintor® (Spinosad), and an absolute control (water) were evaluated individually. The cinnamon extract was the most effective biorational with 73.5 % control, while the mustard extract obtained 32.44 % being the least effective. The previous results show that the thrips fauna in the blueberry crop is diverse and is mostly represented by S. dorsalis, which is a pest species of this crop in other producing states, in addition, biorational products were found with the potential to be incorporated in an integrated thrips management program.
