Alternance of overpopulation of urban insect pests in areas of Cerrado in the north of Minas Gerais, Brazil

摘要

In the present study, we report for the first time the alternance of insect overpopulation pests in urban environment for the north of Minas Gerais, Brazil. The observations were made from November 2017 to November 2018 in the city of Montes Claros and six other towns. During the period of one-year the overpopulation of three species was recorded: Tropidacris collaris (Orthoptera: Romaleidae), Gryllus assimilis (Orthoptera: Gryllidae) and Arthrostictus speciosus (Drury, 1829) (Coleoptera: Carabidae). Considerations about the factors leading to overpopulation of these species in urban areas are also presented.
