In this paper, authors collective present draught effects concerning evolution of the maize leaf weevil (Tanymecus dilaticollis Gyll), in period 2010-2013, at NARDI Fundulea, both at untreated and treated plants. From the years taken in study, the most favourable for the pest attack at untreated maize plants were 2012 and 2013. However in last years, rainfall distribution is not similarly then in the past. In same months we can have periods with draught (more then 10 days without rain) and air high temperatures followed by days with heavy rainfalls and moderate air temperatures. As result, maize leaf weevil attack in 2012 was higher even if total rainfall amount registered in last decade of April and first two decades of May were higher from all four years taken in study. Seed treatment provide good protection for the maize plants in first vegetation stages against this pest, in different climatic conditions from the spring period.
