The southern green stink bug, Nezara viridula (L.), has several genetically determined types, three being the most common in Brazil: G (f. smaragdula - green body), O (f. torquata - green body with lateral and median lobes of the head and anterior margin of the pronotum yellow), and Y (f. aurantiaca - gold or orange body). Nymphal and adult performance of these types was studied at 15ºC/10hL, 22ºC/12hL, and 29ºC/14hL. Mean total nymph mortality in all types at 15ºC/10hL was high (ca. 80%), especially for type G (98%); at 22ºC/12hL, the greatest mortality (55%) occurred in type G, and at 29ºC/14hL in type Y (65%). In general, at combinations of higher temperatures and longer photoperiods, nymphs developed faster. Adult longevity of type G decreased from ca.... |

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... |
