“…Sulphur compounds have been shown to be potent attractants of flower-visiting bats of the genus Glossophaga (von Helversen et al 2000). Although flowers of the New world species Lecythis poiteaui have been reported as breeding sites for stratiomyid flies that are thought to be generalist associates of decaying matter of plant and animal origin (Feinstein et al 2008), these flies do not appear to contribute to pollination of these flowers. Since bat-and carrion fly-pollinated flowers partition their pollinators despite overlap in their volatile blends, we infer that features such as morphological traits (including height above ground), presence and amount of nectar, and acoustic cues play additional roles in the specialisation of these very different pollination systems.…”

Floral mimicry of decaying plant or animal material has evolved in many plant lineages and exploits, for the purpose of pollination, insects seeking oviposition sites. Existing studies suggest that volatile signals play a particularly important role in these mimicry systems. Here, we present the first large-scale phylogenetically informed study of patterns of evolution in the volatile emissions of plants that mimic insect oviposition sites. Multivariate analyses showed strong convergent evolution, represented by distinct clusters in chemical phenotype space of plants that mimic animal carrion, decaying plant material, herbivore dung and omnivore/carnivore faeces respectively. These plants deploy universal infochemicals that serve as indicators for the main nutrients utilised by saprophagous, coprophagous and necrophagous insects. The emission of oligosulphide-dominated volatile blends very similar to those emitted by carrion has evolved independently in at least five plant families (Annonaceae, Apocynaceae, Araceae, Orchidaceae and Rafflesiaceae) and characterises plants associated mainly with pollination by necrophagous flies and beetles.

“…It is also known that myophilous flowers could produce secretion in open shallow nectaries which occur in longitudinal labellar groove in Bulbophyllum family (Endress 1994; Kite et al 1998; Jürgens et al 2006; Johnson and Jürgens 2010; Humeau et al 2011; Davies and Stpiczyńska 2014; Stpiczyńska et al 2015). Whereas the sapromyiophilous pollination syndrome embraces dark flowers (brown, purple, greenish, often with great depth), emitting the putrescent odour containing sulphur compounds (Feinstein et al 2009; van der Pijl and Dodson 1966). In fruit fly-pollinated Bulbophyllum species, methyl eugenol (aromatic compound) and ketones have been identified as key chemical components in plant-pollinator interaction.…”

Flowers of Bulbophyllum weberi and B. cumingii are characterized by fly-pollinated features. The secretory activity was described in dorsal sepals in both species (putative osmophores), petals in B. weberi (possible osmophores) and adaxial surface of lips in both species. In the cells of dorsal sepals and petals of B. weberi proteins, dihydroxyphenols, lipids and starch grains were detected, in lateral sepals—lipids. Whereas in dorsal sepal of B. cumingii only lipids and starch grains were noted, in lateral sepals—proteins and dihydroxyphenols and in petals—proteins and starch grains. The lips in both species differed histochemically and ultrastructurally. The epidermal cells of lip groove in B. weberi contained lipids, proteins, starch grains in cytoplasm, dihydroxyphenols in vacuoles and pectic acids/mucilage on surface. Whereas in B. cumingii—few lipids, starch grains, no proteins, no dihydroxyphenols and no mucilage were noted. Ultrastructurally, in B. weberi, the secretory material was present on surface and vesicles building into plasmalemma, while in B. cumingii—cell wall ingrowths and microchannels in cuticle. The osmiophilic irregular materials and globular, osmiophilic globules in B. weberi are probably tannin-like materials. For the first time, we described the cell wall ingrowths in Bulbophyllum species: in lip of B. cumingii and petals of B. weberi.

“…The plants of families Amaranthaceae and Cucurbitaceae whose genera were not identified are also new records for Merosargus. In fact, Merosargus larvae had only been previously observed in bracts of Heliconia (Heliconiaceae) inflorescences [14][15][16] and fallen flowers of Couratari stellata Smith (Lecythidaceae) [17]. Moreover, Merosargus gracilis had been recorded in another Arecaceae species (Bactris gasipaes Kunth) in the pulp of fruits [18], and not using the trunk or leaves as observed here for the two species of this family: E. edulis and A. aculeatissimum.…”

“…Therefore, resource-use specialization by larvae could be an explanation for the great diversity in the genus. However, information on larval habitats is still very scarce and not species-specific [14][15][16][17][18].…”

The genusMerosargus(Loew) has 142 described species. This great diversity in the genus could be explained by larvae resource-use specialization. However, information on larval habitats is still very scarce. InMerosargusspecies, adult males defend oviposition sites, and this territorial behavior may lead to interspecific competition and make even more important the specialization and niche partitioning to prevent competitive exclusion. This study identified substrate types used as a resource byMerosarguslarvae and investigated the degree of specialization and overlap in resource use by different species at an Atlantic forest remnant in Minas Gerais, Brazil. Every potential resource, especially those with adults in the vicinity, was collected opportunistically from October 2001 to October 2004. In total, 292 individuals from 12Merosargusspecies collected from 21 resource types and 15 plant species were reared in the laboratory. Plant species included herbs, vines, palms, and trees. SixMerosargusspecies were reared from only one resource type, and each resource type was used, on average, by less than twoMerosargusspecies. Thus,Merosargusspecies exhibited a high degree of specialization and small overlap in larval resource selection, which could explain the high local and global diversity of the genus.
