GONZALEZ BACA, Guadalupe et al. Abundance and distribution of entomopathogenic fungi in different locations and environments of southern Tamaulipas. Rev. Mex. Cienc. Agríc [online]. 2019, vol.10, n.3, pp.669-681.  Epub 30-Mar-2020. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v10i3.1550.

In order to generate a register of entomopathogenic fungi with the potential for pest control in the agricultural area of the state of Tamaulipas. In this study, abundance was quantified and the distribution of entomopathogenic fungi determined in different localities and environments of southern Tamaulipas, Mexico. In 2016, entomopathogenic fungi were collected in the Corpus Christi Breccia, Villa Cuauhtémoc, Esteros and Miradores. In each locality the following environments were selected: plots cultivated with grasses (sorghum and corn), fabaceae (soybean, bean and jicama), fruit trees (lemon, papaya, litche, mango and orange), vegetables (onion, chili, tomato and chard) and uncultivated plots (natural environment). In each environment, soil samples were collected. Later, in the collected soil, entomopathogenic fungi were tricked with larvae of Tenebrio molitor L. In total, 134 isolates of the genera were collected: Beauveria sp., Lecanicillium sp., Metarhizium sp., Paecilomyces sp., Trichoderma sp. and Isaria sp. of which, Beauveria sp. presented the greatest abundance and distribution. While, the other genera were collected in specific locations and environments. This result indicates the possibility that the genera of the fungi found are strongly adapted to the biotic and abiotic factors of the environment.
