“…During this period, the soybean crop is cultivated in the central region of Brazil. This synchronisation of the developmental cycle with rainfall and host plant availability has also been observed in congener species, such as P. capillata (Oliveira & Frizzas ) and P. cuyabana (Oliveira et al . ) that also feed on soybeans.…”

“…Behaviours presented by P. nitididorsis , such as the adults swarming with the first rain in September and October; construction of small chambers in the soil for egg deposition; construction of chambers where larvae overwinter the dry season (from April); and the presence of three larval stages, are common features in many species of Melolonthidae that occur in the Brazilian Cerrado (Santos & Ávila ; Rodrigues et al . ; Oliveira & Frizzas , ; Pereira et al . ; Souza et al .…”

“…The larval stage is the longest stage of development in melolonthids (Oliveira et al . ; Oliveira & Frizzas, , ). The larval phase of P. nitididorsis lasted for approximately 20 months (≈607 days) corresponding to 83.3% of the total duration of the developmental cycle.…”

“…Other species of Phyllophaga with an annual developmental cycle, such as P. capillata and P. cuyabana in Brazil and Phyllophaga menetriesi Blanchard in Colombia, exhibit larval stages that last approximately 8 months (Oliveira et al . ; Pardo‐Locarno & Montoya‐Lerma ; Oliveira & Frizzas ). The only other species with a biennial cycle in Brazil is P. triticophaga , which occurs in the state of Rio Grande do Sul.…”

“…The known host of these species is soybeans, and they exhibit an annual life cycle (Oliveira et al . ; Oliveira & Frizzas ). Phyllophaga triticophaga Morón & Salvadori occurs in a humid subtropical climate zone in Rio Grande do Sul (Cfa climate sensu Alvares et al .…”

Phyllophaga nitididorsis Frey, a species native to Brazil, has recently been recorded as a soil pest in soybean Glycine max (L.) Merr. fields in the north-west region of Minas Gerais (MG), Brazil. Our study aimed to evaluate the phenology of P. nitididorsis in the Cerrado of Central Brazil. The study was conducted in a field (≈300 ha) in Buritis/MG where soybean is sown in October (spring) annually. Monthly (December 2012-November 2014) samples were collected by opening trenches (50 cm × 50 cm and 30 cm in depth), recording the developmental phases of all P. nitididorsis found. Specimens collected from the field were maintained in the laboratory at 25 (±2°C), and their development was recorded at weekly intervals. Light traps were installed in the states of Minas Gerais, Goiás (GO), and the Federal District (DF) to verify species distribution. P. nitididorsis exhibited a biennial life cycle that lasted approximately 22 months, from egg to inactive adult, and 24 months from egg until the emergence of active adults. Eggs were found in the soil in November. The larval stage lasted about 20 months (≈607 days). Second-instar and third-instar larvae constructed chambers in the soil to overwinter during the dry season (March to September) during the first and second years of development, respectively. Pre-pupae were observed between July and August and pupae between July and September. Inactive adults occurred in August and September, and the swarming period was between October and November. Adult P. nitididorsis were caught in all of the States where light traps were operated. The active phases of the insect (larvae and adults) were synchronised with soybean cultivation and the rainy season (October and March) in the Cerrado. To the best of our knowledge, our study is the first to report P. nitididorsis in the states of Goiás and the Federal District. Further, this species is the first biennial melolonthid observed in the Brazilian Cerrado.

Mark-release-recapture studies have been used to evaluate the dispersal ability of different insect species.In the eld, we evaluated the dispersal ability of the soil pest species Phyllophaga capillata (Blanchard) (Coleoptera: Melolonthidae) in soybean (Glycine max L.) crop, and the ight activity of this species under controlled conditions. Field studies were conducted on a soybean seed production farm in Planaltina/DF, Brazil. On four dates, adults of P. capillata were collected, sexed, marked and released in a soybean plot (~ 230 ha). Twelve light traps were set in three concentric circles, with four traps each, at distances of 50, 150 and 250 m from the point of adult release. Under controlled conditions, groups of adults (males and females) were separated into pots containing soil, and the ight ability of the specimens was evaluated daily for 72 h. The average recapture rate of adults was 1.93% for the four collection dates. The highest recapture rate was observed at a distance of 50 m, at the beginning and middle of the swarming period, and at 250 m at the end of the swarm. Males, in general, were more active than females and reached the greatest distance of displacement (250 m). Most specimens (69.5% of males and 52.9% of females) were prone to leave the ground on the three consecutive days of the study. These results provide insights for understanding the dispersal patterns of this pest species in agricultural landscapes.
