ALVAREZ-RAMOS, Ricardo et al. Seasonal abundance of Diaphorina citri associated with the phenology of citrus crops. Rev. Mex. Cienc. Agríc [online]. 2022, vol.13, n.1, pp.89-101.  Epub 02-Maio-2022. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v13i1.2494.

In the present research, the participation of the phenology of the Valencia orange (Citrus sinensis L. Osbeck) and Italian lemon (Citrus limon L. Burn f.) crops in the seasonal abundance of Diaphorina citri Kuwayama was determined. The study was carried out during the years 2015 to 2018 in three regional control areas (ARCOs), located in the municipalities of Padilla, El Barretal, El Carmen, Estación Santa Engracia, Güémez and Victoria, Tamaulipas. In these areas, the abundance of D. citri in each phenological phase of the orange crop (ARCO 1 and 2) and lemon (ARCO 3) was recorded. The Italian lemon crop produced shoots all year round. Meanwhile, the Valencia orange crop presented a phase of dormancy. In the four years, the seasonal abundance of D. citri behaved differently in the three ARCOs. The greatest abundance of the insect occurred in the phase of shoot production in trees. The result obtained in the present work could be used to define the period of application of the insecticides recommended for the control of D. citri in the ARCOs.
