Relationship between neoathyreus sp and weather

Study the meteorological factors is important to understand Neoathyreus sp population dynamics.So this study examined the relationship between meteorological conditions and the Neoathyreus sp population fluctuation in Cocal Mata in Teresina-PI city, Brazil, from August 2011 to July 2012.Neoathyreus sp were collected weekly in 12 pitfall traps unattractive.During the period analyzed only in the months of February to April of 2012 was registered the presence of this species.There was a significant and negative association between the registration of the population fluctuation to the insolation (r=-0.61;p-value< 0.05) and the average temperature of the compensated air (r=-0.55;p-value< 0.10) and positive to the pluviometric precipitation (r=0.69;p-value< 0.05).Thus it was evidenced that there is species seasonality associated with Cocal Mata.
