LOPEZ-MORA, Jesús Fernando et al. Bruchids (Insecta: Coleoptera) associated with fabaceae seeds in North Sinaloa, Mexico. Acta Zool. Mex [online]. 2021, vol.37, e3712309.  Epub 05-Feb-2021. ISSN 2448-8445.  https://doi.org/10.21829/azm.2021.3712309.

Fabaceae represent an important source of resources when are used in coal production, feeding of livestock and people, in addition to avoiding soil erosions; these plants are threatened in their production by the presence of bruchids or weevils (Insecta: Coleoptera), who feed on their seeds to survive, causing economic losses in the region. In 2017, seed collections were carried out in four municipalities in the North of Sinaloa, with the objective of identifying the bruquid species associated with Fabaceae and assessing their damage on the germination of seeds. 25 species of Fabaceae were identified: Ahome (7), El Fuerte (6), Guasave (6) and Choix (6). From 68,340 seeds, 19,396 adult weevils emerged, grouped into seven genera and 14 species, with dominance in species of Mimosestes (3), Acanthoscelides (3), Merobruchus (3), and Stator (2). Of the plant species, 17 were attacked by a kind of bruquid and six by two; in Ahome the most harmful pest species was Merobruchus santarosae, with 43.9% and 33.1% damage to Mariosouza coultieri and M. acatlensis, respectively; in El Fuerte, Acanthoscelides desmanthi caused 38.95% damage to Sesvania herbaceae and 29.48% to S. occidentalis; in Guasave, the greatest damages corresponded to Callosobruchus maculatus on Cicer arietinum (41.3%), Mimosestes ulkei on Parkinsonia aculeata (40.6%) and M. mimosae on P. florida (37.7%); in Choix, the greatest damages corresponded to Merobruchus insolitus on Albizia sinaloensis (34.7%) and Amblycerus acapulcencis on Caesalpinia cacalaco (29.1%).
