Nezara viridula (L.) is a cosmopolitan and polymorphic pentatomid. Several genetically determined types have been described due to body color variation in adults. A survey covering 13 Brazilian states was conducted during 2001 and 2002 to determine the geographical distribution of the main types. Type G (smaragdula - body entirely green), the most common, showed a wide distribution, from south to north (latitude 2°49' N to 31°46' S), except in the Central-West Region.Type O (torquata - body green with lateral and median lobes of the head and anterior margin of the pronotum yellow), less abundant than the former, was more frequent at latitudes> 23°18' S and mean annual temperatures < 20.8°C (Southem Region). Type Y (aurantiaca - body entirely gold or orange), which is rare, was collected only in the Southem Region. N viridula (smaragdula) was captured in only one place in the Northem Region (Boa Vista, RR, latitude 2°49' N). The abundance ofthe two most common types, smaragdula and torquata, was not correlated with altitude.
