“…The pollination of different species of Zamiaceae seems to be mediated by host-specific insects, typically Coleoptera and Thysanoptera (Franz & Skelley, 2008;Tang, Skelley, & Pe´rez-Farrera, 2018;Terry et al, 2004;Terry, Forster, Moore, Roemer, & Machin, 2008;Valencia-Montoya et al, 2017). We prepared a timeline of the main studies addressing the pollination biology of Zamiaceae species (Figure 4).…”

Studies involving cone odor, thermogenesis, and cycad pollinators as for Encephalartos (Suinyuy, Donaldson, & Johnson, 2013a, 2013b, 2015 and Macrozamia of the Old World (Terry et al, 2004;Terry, Roemer, Walter, & Booth, 2014;Terry, Roemer, Booth, Moore, & Walter, 2016) and Zamia of the New World (Valencia-Montoya et al, 2017) are recommended for cycads of South America. Further studies on chemical signal perception and cognition of the beetle pollinators, together with efforts to resolve the detailed phylogeny of cycads and their associated pollinators, will improve our understanding of cycadinsect mutualism (Suinyuy et al, 2015).…”

Zamiaceae, a family of the ancient order Cycadales, is distributed throughout the tropical and subtropical regions of both the Old and New Worlds. Here, we present a systematic review of Zamiaceae with emphasis on Zamia species from South America. We aim to (a) establish the current knowledge, (b) identify research gaps, and (c) indicate directions for future studies, discussing ecology and conservation of South America species. The search recovered 508 papers, further classified into 11 research topics: taxonomy and systematics, morphology, biochemistry, genetics, phylogeography, population ecology, reproductive biology, ecological interactions, plant propagation, conservation, and reviews. The number of publications doubled in the 21st century, mostly focusing on genetics (n ¼ 60), taxonomy and systematics (n ¼ 52), morphology (n ¼ 36), ecological interactions (n ¼ 30), and an increasing interest in population ecology (n ¼ 29) and conservation (n ¼ 32). Studies are concentrated in North and Central America (54% of all studies) with just 6% (29) addressing South America species of Zamia. Overall, studies point out the key role of pollinators in promoting gene flow through pollen dispersal among populations of Zamiaceae. Therefore, investigate natural history, ecology, reproductive biology, genetic, and phylogeography, especially for South America species, are needed. Moreover, the implementation of in situ and ex situ collections and germplasm banks linked to botanical gardens are essential for the conservation and reestablishment of local populations of critically endangered Zamia species in South America. Concomitantly, we suggest studies modeling the distribution of Zamia species in future climate change scenarios.

“…Specialized coleopteran pollination is widespread in extant Cycadales (3,4) and has existed in the lineage since at least the mid-Mesozoic where fossilized Boganiidae beetle pollinators have been found (18) well before the rise of flowering plants (19) or the earliest known direct evidence of thrips pollination (20). While push-pull pollination has also been hypothesized for Coleopterapollinated cycads (21,22), the mechanism by which the plants manipulate their behavior to carry out pollination has not yet been explored.…”

An ancient push-pull pollination mechanism in cycads

Most cycads engage in brood-site pollination mutualisms, yet the mechanism by which the Cycadales entice pollination services from diverse insect mutualists remains unknown. Here, we characterize a push-pull pollination mechanism between a New World cycad and its weevil pollinators that mirrors the mechanism between a distantly related Old World cycad and its thrips pollinators. The behavioral convergence between weevils and thrips, combined with molecular phylogenetic dating and a meta-analysis of thermogenesis and coordinated patterns of volatile attraction and repulsion suggest that a push-pull pollination mutualism strategy is ancestral in this ancient, dioecious plant group. Hence, it may represent one of the earliest insect/plant pollination mechanisms, arising long before the evolution of visual floral signaling commonly used by flowering plants.

“…We highlight several promising research questions in Box 1. Future studies would do well to consider other insect groups too, as cycadivory has been reported among larvae and adults of non‐pollinating beetles (Coleoptera; Marler and Muniappan, 2006); bees (Hymenoptera; DeVries, 1983; Ornduff, 1991; Valencia‐Montoya et al ., 2017); leaf‐mining larvae of an unidentified fly (Diptera; DeVries, 1983); termites (Blattodea; Marler et al ., 2011); and phloem‐feeding scale insects and mealybugs (Hemiptera; Castillo‐Guevara and Rico‐Gray, 2003; Marler and Muniappan, 2006). By summarising what is known about the phylogenetic placement of cycadivorous Lepidoptera, along with their hostplant relationships and defensive ecology, we introduce them as a compelling study system with great promise for investigating the causes and consequences of ecological interactions.…”

Ecology and evolution of cycad‐feeding Lepidoptera

Cycads are an ancient group of tropical gymnosperms that are toxic to most animals – including humans – though the larvae of many moths and butterflies (order: Lepidoptera) feed on cycads with apparent immunity. These insects belong to distinct lineages with varying degrees of specialisation and diverse feeding ecologies, presenting numerous opportunities for comparative studies of chemically mediated eco‐evolutionary dynamics. This review presents the first evolutionary evaluation of cycad‐feeding among Lepidoptera along with a comprehensive review of their ecology. Our analysis suggests that multiple lineages have independently colonised cycads from angiosperm hosts, yet only a few clades appear to have radiated following their transitions to cycads. Defensive traits are likely important for diversification, as many cycad specialists are warningly coloured and sequester cycad toxins. The butterfly family Lycaenidae appears to be particularly predisposed to cycad‐feeding and several cycadivorous lycaenids are warningly coloured and chemically defended. Cycad–herbivore interactions provide a promising but underutilised study system for investigating plant–insect coevolution, convergent and divergent adaptations, and the multi‐trophic significance of defensive traits; therefore the review ends by suggesting specific research gaps that would be fruitfully addressed in Lepidoptera and other cycad‐feeding insects.
