Diversidad de reduviidae (Hemiptera: Hetero Ptera) en tres fragmentos de bosque tropical (BST) en el departa mento del Atlántico, Colombia

Abstract

The variation of diversity of Reduviidae (Hemiptera) in three fragments of Tropical Dry Forest (Reserva Campesina La Montaña= RCM, La Esmeralda= L.E and Puerto Colombia= P.Col) from November 2012 to June 2013 in the department of Atlántico was analyzed. A lineal transect of 600 m was installed in each fragment. Ten points were marked and separated every 50 m. The Reduviidae were collected those points using hitting (agitation of bushes), sifting of leaf litter and manual gathering. Four light traps were also installed (two white and two purple) every 150 meters. Two hundred and sixty-five specimens were captured. They represented 19 genera and 9 subfamilies. The most diverse subfamily was the Harpactorinae with 37% of the total 143. The Zelurus Hahn was the most common genera with 143 specimens which was directly related to the rainy season in the area. On the other hand, the L.E and the RCM fragments had the highest population of Reduviidae with 13 genera in each one. The highest population was in May with 155 specimens. The composition of Reduviidae varied during the time and through the space in the DTF fragments in the department of Atlantico which shows that this family depend on micro-habitat availability, food sources and changes in the vegetation in the these ecosystems.
