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 2º 49' N to 31º 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 > 23º18' S and mean annual temperatures < 20.8ºC (Southern Region). Type Y (aurantiaca - body entirely gold... |
