 pt Biodiversidade de polinizadores e biologia floral em cultura de berinjela ( Solanum melongena check for this species in other resources )
Montemor, Kleber A. & Malerbo Souza, Darclet T.

Resumo

Este experimento foi conduzido em Ribeirão Preto, SP, Brasil, em 2006 e 2007 e teve como objetivo identificar os agentes polinizadores e o comportamento (freqüência, constância, coleta de néctar e de pólen) desses insetos nas flores da cultura da berinjela ( Solanum melongena check for this species in other resources L.). Para isso, observou-se a freqüência dos insetos, nos primeiros 10 minutos em cada horário, das 7:00 às 18:00 h, com três repetições (dias distintos). Observou-se que não há um horário definido para a abertura das flores da berinjela. Os insetos visitantes das flores, em 2006, foram Exomalopsis check for this species in other resources sp. (29,9%), Pseudaugochloropsis gramínea check for this species in other resources (23,9%), Bombus atratus check for this species in other resources (20,9%), Oxaea flavescens check for this species in other resources (19,1%) e Trigona spinipes check for this species in other resources (6,2%). Em 2007, foram B. atratus (38,6%), P. gramínea (25,9%), Exomalopsis sp. (21,3%) e O. flavescens (14,2%). Todos esses insetos coletaram apenas pólen das flores e apenas T. spinipes não apresentou comportamento vibratório. Exomalopsis sp., P. gramínea e B. atratus foram consideradas importantes polinizadores dessa espécie vegetal. A presença dessas abelhas aumentou a produção de berinjelas.

Abstract

The present experiment was carried out at Ribeirão Preto, SP, Brazil, in 2006 and 2007 with the objective to identify the pollinators and the behavior (frequency, constancy, nectar, and pollen collection) of insects on flowers of eggplant crop ( Solanum melongena check for this species in other resources L.). For this, there were recorded the frequency of the insects (counted during ten min, every hour) from 7:00 to 18:00 h with three replications (different days). The eggplant flowers did not show a specific time to open. Exomalopsis check for this species in other resources sp., Pseudaugochloropsis gramínea check for this species in other resources , Bombus atratus check for this species in other resources , Oxaea flavescens check for this species in other resources , and Trigona spinipes check for this species in other resources were the visitors on egg plant flowers in 2006 (29.9, 23.9, 20.9, 19.1, and 6.2%, respectively) and B. atratus, P. gramínea, Exomalopsis sp. e O. flavescens (38.6, 25.9, 21.3, and 14.2%, respectively) in 2007. The evaluated bees collected only pollen from flowers and only T. spinipes did not present a vibrate forage behavior. Exomalopsis sp., P. gramínea, and B. atratus were considered important pollinators of this vegetable species. The presence of these bees increased eggplant production.
