The study was conducted to know the host plants of adult insects of lamellicorn beetles related to agricultural areas, such as tropical deciduous forest, spiny forest, and xerophilous brush from the northern region of Sinaloa state, México. The data were collected in the morning and evening from August to October 2008. The 18 adult species collected were included in the genera: Diplotaxis, Phyllophaga, Pelidnota, Cyclocephala, Oxygrylius, Cotinis, Euphoria, and Hybosorus, of which Phyllophaga was the genus with the highest number of host species, with 15 species of plants in total, belonging to 10 plant families. The plants used as food by lamellicorn beetles belong to 26 species and 15 families, of which the Fabacea family was the most visited. Within this family the “bacaporo”, Parkinsonia aculeate was preferred by a total of 11 species of beetles.
