 es Diversidad de la comunidad de abejas sin aguijón (Hymenoptera: Apidae: Meliponina) en bosque seco tropical en Venezuela
Parilli, Severiano Rodríguez; Manrique, Antonio & Velásquez, Mercedes

Resumen

Las abejas sin aguijón (ASA) cumplen funciones ambientales indispensables mediante la polinización y son susceptibles a ser utilizadas en la producción agrícola. Con el objeto de conocer las ASA presentes en 10.000 m2 de bosque seco tropical en San Juan de los Morros, estado Guárico, Venezuela, se procedió a realizar una evaluación de su diversidad, para lo cual se realizaron 24 muestreos distribuidos uniformemente entre los meses de julio a diciembre de 2004. Se obtuvieron 44 individuos pertenecientes a nueve especies, las cuales se ordenaron según su abundancia: Trigona check for this species in other resources sp1> Nannotrigona testaceicornis check for this species in other resources > Tetragonisca angustula check for this species in other resources > Plebeia check for this species in other resources sp 2 > Trigonisca check for this species in other resources sp > Trigona amaltea check for this species in other resources > Plebeia check for this species in other resources sp 1 > Trigona sp 2 > Partamona check for this species in other resources sp. Trigona sp 1 fue la especie mas constante y frecuente. N. testaceicornis y T. angustula fueron las especies frecuentes de ocurrencia accesorias. Los índices faunísticos obtenidos fueron: diversidad de Margalef (8,74), diversidad de Shannon - Wiener (1,92) y equidad de Simpson (0,18). Los meses con mayores riquezas de especies y abundancia de individuos fueron septiembre y octubre. La familia Piperaceae registró el mayor número de visitas por las ASA.

 en Community’s diversity of stingless bees (Hymenoptera: Apidae: Meliponina) in a Venezuela tropical dry forest
Parilli, Severiano Rodríguez; Manrique, Antonio & Velásquez, Mercedes

Abstract

The stingless bees (SB) complete environmental indispensable functions by means of the pollination and they are susceptible to be used in the agricultural production. In order to know the SB present in 10,000 m2 of tropical dry forest in San Juan de Los Morros, Guárico state, Venezuela; a diversity evaluation was carried out. Twenty four samplings distributed evenly among the months from July to December 2004. Forty four individuals belonging to nine species were accounted for and ordered according to their abundance as: Trigona check for this species in other resources sp 1 > Nannotrigona testaceicornis check for this species in other resources > Tetragonisca angustula check for this species in other resources > Plebeia check for this species in other resources sp 2 > Trigonisca check for this species in other resources sp. > Trigona amaltea check for this species in other resources > Plebeia check for this species in other resources sp1 > Trigona sp 2 > Partamona check for this species in other resources sp. Trigona sp 1 was the most constant and frequent species. N. testaceicornis and T. angustula were the accessory and frequent species in this habitat. The values obtained from index ecology were: Margalef diversity (8.74), Shannon - Wiener diversity (1.92), and Simpson index (0.18). The months with higher richness and individuals’ abundance were september and october, and the family Piperaceae registered the biggest number of visits by the SB.
