Cyclocephline scarabs and their host plants are documented as highly specialized plant–pollinator associations, with various fine-tuned adaptations. We studied the association between Philodendron adamantinum, a species endemic to Espinhaço Range in Minas Gerais, South-East Brazil, its exclusive pollinators. focused on pollination mechanism reproductive success of P. analysed floral scent composition, performed field bioassays verify scent-mediated attraction The adamantinum depends presence...
Philodendron acutatum (Araceae) is a hemiepiphyte common to the Atlantic Forest of northeastern Brazil. In two localities, we studied species' breeding system and associations with flower‐visiting insects, along an analysis its floral scent composition. The fruit set self‐incompatible P. was high, more than 90%, inflorescences were exclusively pollinated by one species scarab beetle, Cyclocephala celata (Scarabaeidae, Dynastinae). Pollinators are drawn toward at dusk strong fragrances given...
Abstract: Flowering, pollination ecology, and floral thermogenesis of Caladium bicolor were studied in the Atlantic Rainforest Pernambuco, NE Brazil. Inflorescences this species are adapted to characteristic syndrome performed by Cyclocephalini beetles. They bear nutritious rewards inside well‐developed chambers exhibit a thermogenic cycle which is synchronized activity period visiting Heating intervals spadix observed during consecutive evenings corresponding beginning female male phases...
Taccarum ulei (Araceae, Spathicarpeae) is a seasonal geophytic aroid, native to north-eastern Brazil, that flowers during two months of the rainy season. Patterns floral thermogenesis, pollination biology, and traits associated with syndromes were studied compared those other Araceae. Two species cyclocephaline scarabs (Scarabaeidae, Cyclocephalini) recognized as effective pollinators: Cyclocephala celata cearae. Larvae an unidentified fruit fly (Melanoloma spp., Richardiidae, Diptera) also...
2-Alkyl-3-methoxypyrazines (MPs) are naturally occurring aromatic compounds involved in insect chemical communication as both pheromones and allelochemicals. Although rarely characterized floral scents, they have been identified major constituents headspace samples from palm inflorescences evidence pointed towards their function attractive cues for scent-oriented pollinators, well florivores. In this study, we investigated the occurrence of MPs economically exploitable palms belonging to...
Abstract Several monoecious species of palms have developed complex strategies to promote cross‐pollination, including the production large quantities floral resources and emission scents that are attractive pollinators. Syagrus coronata constitutes an interesting model with which understand evolution plant reproductive in a adapted seasonally dry forests. We monitored blooming phenology over 1 year, during we also collected identified visitors putative potential visitor attractants by...
Nocturnal flowering plants often release strong scents to attract their pollinators. Among night active flower visitors are cyclocephaline scarab beetles, which have been demonstrated respond uncommon volatile organic compounds released in high amounts by host plants. In Araceae, the molecular structure of several such is yet be unveiled. We investigated headspace floral scent samples Philodendron squamiferum, Thaumatophyllum mello-baretoanum, and Xanthosoma hylaeae a variety approaches,...
In this study, the flowering mechanisms and pollination strategies of seven species highly diverse genus Homalomena (Araceae) were investigated in native populations West Sarawak, Borneo. The floral scent compositions also recorded for six these species. selected taxa belong to three out four complexes section Cyrtocladon (Hanneae, Giamensis Borneensis). belonging Hanneae complex exhibited longer anthesis (53-62 h) than those Borneensis (ca. 30 h). Species underwent two emission events...
AbstractWe collected 76 specimens of the Cyclocephala celata Dechambre in Igarassu, Pernambuco, Brazil, March 2008 for captive breeding and rearing to document its life cycle describe immatures. A total 98 eggs was obtained from captive-reared insects, each individually enclosed an egg chamber assembled with surrounding substrate. Viability highest phase (92.8%). Pupae were pupal cells. The duration 164 days (n = 2), only 2% developed into adults. Third instar characters documented first...
Abstract The environmental unsustainability of African oil palm crops is a growing worldwide concern, and the macauba in tropical Southern America surges as most viable substitute for production first‐generation biodiesel renewable fuel. Large‐scale cultivation palm, however, bound to suffer major setback due fast emergence florivorous pest threat, Cyclocephala forsteri , scarab beetle species that can severely reduce fruit yield. Like other congenerics, female male C. are night‐foraging...
Adults of Cyclocephala distincta are flower visitors Neotropical palms (Arecaceae) and commonly found in the Atlantic Forest Pernambuco, Brazil.Males females were collected wild subjected to captive rearing breeding.The egg hatching rate, life cycle, longevity immatures adults, oviposition parameters captivity analyzed.The average duration cycle C. was 108.2 days (n = 45).The stage lasted on 10.9 days, egg-hatching rate 73.9%.The immature 93.4 days.The larvae exhibited negative phototaxis,...
Solitary, dioecious, and mostly endemic to Andean cloud forests, wax palms (Ceroxylon Bonpl. ex DC. spp.) are currently under worrisome conservation status. The establishment of management plans for their dwindling populations rely on detailed biological data, including reproductive ecology. As in the case numerous other Neotropical palm taxa, small beetles assumed be selective pollinators palms, but identity relevance successful fruit yield were unknown. During three consecutive seasons we...
The uncommon jasmone derivatives dehydrojasmone, isojasmol, and isojasmyl acetate, floral scent compounds from night-blooming Araceae, were synthesized in a scalable synthesis employing conjugate addition with selenoacetal as the key step. stereoselective strategy subsequent enzymatic kinetic resolution allowed determining absolute configuration of natural by GC on chiral phase. homoterpene (E)-4,8-dimethyl-1,3,7-nonatrien-5-yl another compound, was obtained α-regioselective aldehyde...
1. Food choice may change depending on sex, age, and physiological condition due to nutritional requirements or because of mechanisms that promote food recognition. Among dung beetles, some species are attracted both carrion dung, but why males females more either resource remains unclear. This study aimed investigate whether body size, (body dry mass, lipid muscle mass) age (young, mature, old) affect attraction in two Dichotomius iannuzziae D. gilletti . 2. was carried out remnants...
In order to obtain information on the biology of masked chafer, Cyclocephala paraguayensis Arrow (Scarabaeidae: Dynastinae: Cyclocephalini), and its immature morphology, beetle life cycle was studied under laboratory conditions. After field collection, adults were placed inside containers filled with soil obtained in original capture provide an oviposition site after mating ocurred. Eggs collected daily isolated for manipulation experiments observations. Detailed about eggs, instars...
The larval instars and pupa of Cyclocephala distincta Burmeister (Coleoptera: Scarabaeidae: Dynastinae: Cyclocephalini) are described compared to those other known congenerics. Adult C. distincta, specialized flower visitors Neotropical palms (Arecaceae), were collected in an area native Atlantic Forest cover the northeastern coast Brazil reared captivity. larvae diff---er from congenerics because a distinctive pattern arrangement setae on raster.
