“…The species Megachilinae sp.6, Apis mellifera and Xylocopa frontalis were classified as constants. Pollination of other Convolvulaceae species by Megachilinae and Apis melifera was also recorded (Kiill and Ranga, 2003;Kiill and Simão-Bianchini, 2011).…”

Abstract This study aimed to evaluate the effects of florivory and of the patrolling ants associated to EFNs-extrafloral nectaries, on the frequency of floral visitors, using the specie Ipomoea carnea subs. fistulosa (Martius and Choise) in Caatinga area. The floral attributes of the species were characterized. The effect of florivoria on the frequency of visitors and the influence of the presence of ants associated with the NEFs on the pollinator visit rate were evaluated. The rate of natural florivoria was recorded and collected floral visitors and ants over eight months. The damage on floral structure and the presence of ants foraging in the flowers causes a decrease in the number of total visits. The results may be justified by the fact that the floral damage consisted in the loss of important floral attributes. These effects for Ipomoea carnea subs. fistulosa can affect reproductive success, since it is a self-incompatible species and depends on the activity of the pollinators for their fertilization to occur.

“…Bees were the most frequent and common, especially species of Apidae and Halictidae which collected nectar and/or pollen. Others authors studying the Convolvulaceae family also noted the importance of Apidae bees, which usually prevailed in number of species and individuals on flowers (Piedade- Kiill & Ranga, 2000;Kiill & Simão-Bianchini, 2011;Pacheco Filho et al, 2011;Paz et al, 2013).…”

This strategy has also been described for other species of the genus Jacquemontia as: J. nodiflora (Kiill & Simão-Bianchini, 2011), J. montana (Silva et al, 2010), J. multiflora (Piedade-Kiill & Ranga, 2000). These characteristics are essentials, especially because many species of Convolvulaceae are creeping plants that occur in open areas with high light incidence, characteristics of anthropogenic environments.…”

ABSTRACT. The family Convolvulaceae is widely distributed in tropical regions, mainly in open areas. Convolvulaceae fl owers are characterized mainly by being beautiful and ephemeral, attracting many fl ower visitors that belong to diff erent taxonomic groups. This work aimed to investigate the interactions between insects and fl owers of Jacquemontia bracteosa (Convolvulaceae), focusing on the pollination effi ciency, in an area in the Brazilian semiarid. From November 2011 to October 2012, fl oral biology of J. bracteosa was investigated as well as the fl ower visit frequency, behavior, and morphology of fl oral visitors. The fl owers of J. bracteosa are white, showy and open early in the morning, lasting less than 12 hours, with fruiting occurring both by selfi ng and outcrossing fecundation. A total of 337 specimens insects were collected on J. bracteosa fl owers during the fi eld observations. The Neotropical bee, Ancyloscelis apiformis, was considered the most effi cient pollinator of J. bracteosa. This bee showed appropriate behavior, high frequency (64% of the total sample), and was constant on the fl owers. Furthermore, they arrived soon when the fl owers began to open and presented 90% of effi ciency in tests of fl ower pollination of J. bracteosa. Other native bee species also visited the fl owers of J. bracteosa and may be considered potential pollinators because they presented behavior and morphology compatible with the fl owers. This study suggests that maintenance of weeds or ruderal plants, especially those that also have ornamental potential in anthropic area, may be an option for the preservation of local native pollinators, which are threatened by environmental degradation.

“…Neste estudo, A. mellifera foi o polinizador mais frequente e abundante, similar ao registrado em outros estudos feitos na caatinga (MACHADO, 1990;KIILL et al, 2010;KIILL;BIANCHINI, 2011), reforçando a indicação de abelha altamente generalista, cuja dieta inclui plantas dos mais diversos grupos.…”

RESUMO -O objetivo deste trabalho foi estudar a fenologia, biologia reprodutiva e visitantes florais de Sideroxylon obtusifolium em área de caatinga. O estudo foi realizado de outubro de 2003 a setembro de 2005, em populações naturais de S. obtusifolium, na Reserva Legal do Projeto Salitre, em Juazeiro, BA. Os dados fenológicos indicaram que as fenofases vegetativas (brotação e senescência foliar) ocorreram ao longo do ano, enquanto a floração e frutificação foram registradas na estação seca e das chuvas, respectivamente. As flores são hermafroditas, de coloração creme, exalam odor, secretam pequena quantidade de néctar (< 1 μl) e apresentam antese diurna e dicogamia protogínica. Entre os visitantes florais, foram registradas abelhas, vespas, moscas e borboletas. Apis mellifera e os dípteros morfoespécie 1 e 2 foram considerados polinizadores dessa sapotácea. Quanto ao sistema de reprodução, S. obtusifolium é autógama facultativa, produzindo frutos por autopolinização (6,6%) e por polinização cruzada (33%). Diferenças no registro fenológico, na biologia floral e nos agentes polinizadores foram encontradas, em comparação com outros ambientes, indicando que as variáveis climáticas podem ser um dos diversos fatores que influenciam essa relação.Palavras-chave: Caatinga; Protoginia; Miofilia.
