Abstract

RODRIGUEZ BERRIO, Alexander  and  GUTIERREZ BUSTAMANTE, Silvia. The Campopleginae (Hymenoptera, Ichneumonidae) wasp subfamily, in the Cañete - Lunahuaná River Valley, Peru. Ecol. apl. [online]. 2014, vol.13, n.2, pp.147-152. ISSN 1726-2216.

The study was performed during one calendar year to determine the diversity of the Campopleginae wasp subfamily, present in the following four localities with different altitudes, along the Cañete - Lunahuana valley, Province of Lima, Peru: Encañada (200 m), San Jerónimo (400 m), Pacarán (600 m), and Zúñiga (800 m). The samples were collected in the vicinity of cultivated fields by using Malaise traps, placed above wild shrubs and herbs. 941 specimens in the Subfamily were collected belonging to the following genera: Campoletis, Campoplex, Casinaria, Diadegma, Microcharops, Prochas, and Venturia. The highest species richness level was found at Encañada (23 morphospecies), and the highest number of collected specimens were obtained at San Jerónimo (362 individuals). Microcharops represent 75 % of the Campopleginae fauna found in the studied area, being the most dominant genus; followed in importance by Campoletis with 8.9 %, and Venturia with 8.7 %. With respect to the sex ratio 1.48 more males than females were trapped. For the first time Microcharops taiticus and Microcharops niger were recorded for Peru; the first species being more variable (with four morphotypes) than the second one.
