“…Some bee species also visit papaya on other continents (Australia and Africa) where this crop was introduced; however, some authors have suggested that the main pollinators are hawk moths (Garrett, ; Martins & Johnson, ). Although hawk months visit papaya flowers in the study area, these are infrequent visitors (Moo‐Aldana et al, ) and the proboscis of the species reported in the area ( Cautethia yucatana and Manduca sp. Montero‐Muñoz, Pozo, & Cepeda‐González, ) is far longer (6.5 ± 1.2 cm [hereafter mean values ±1 SE ]) than the corollas of female flowers (2.1 ± 0.4 cm).…”

“…Cultivated papaya coexists with its wild relative (Fuentes & Santamaría, ), the latter occurring sparsely within the area sampled. The co‐occurrence of wild and cultivated papaya is relevant because these varieties have similar floral morphology and share several pollinator species (Moo‐Aldana et al, ). Most plants in the study area (including papaya) have entomophilous flowers and are visited mainly by bees (Badillo‐Montaño et al, ).…”

“…In the study area, andromonoecy is the most common sexual expression and male is the rarest. Papaya is mainly pollinated by generalist diurnal insects (bees and Lepidoptera) in the study area (Badillo‐Montaño et al, ; Moo‐Aldana et al, ). Some bee species also visit papaya on other continents (Australia and Africa) where this crop was introduced; however, some authors have suggested that the main pollinators are hawk moths (Garrett, ; Martins & Johnson, ).…”

“…Although modern papaya varieties can also produce self‐compatible hermaphrodite flowers, previous studies suggest that pollen deposition by pollinators on these flowers significantly increases fruit set and weight (Badillo‐Montaño, Aguirre, Santamaría, Martínez‐Natarén, & Munguía‐Rosas, ; Garrett, ; Martins & Johnson, ). Fruit set in the absence of pollinators is also less attractive to customers owing to the reduced size and round shape of the fruit (Martins & Johnson, ; Moo‐Aldana et al, ). In the study area, cultivated papaya blooms year round and is visited by a wide variety of generalist insects (Moo‐Aldana et al, ) that also visit many other wild and cultivated plant species around papaya plantations (Badillo‐Montaño et al, ).…”

Many modern crop varieties rely on animal pollination to set fruit and seeds. Intensive crop plantations usually do not provide suitable habitats for pollinators so crop yield may depend on the surrounding vegetation to maintain pollination services. However, little is known about the effect of pollinator‐mediated interactions among co‐flowering plants on crop yield or the underlying mechanisms. Plant reproductive success is complex, involving several pre‐ and post‐pollination events; however, the current literature has mainly focused on pre‐pollination events in natural plant communities. We assessed pollinator sharing and the contribution to pollinator diet in a community of wild and cultivated plants that co‐flower with a focal papaya plantation. In addition, we assessed heterospecific pollen transfer to the stigmatic loads of papaya and its effect on fruit and seed production. We found that papaya shared at least one pollinator species with the majority of the co‐flowering plants. Despite this, heterospecific pollen transfer in cultivated papaya was low in open‐pollinated flowers. Hand‐pollination experiments suggest that heterospecific pollen transfer has no negative effect on fruit production or weight, but does reduce seed production. These results suggest that co‐flowering plants offer valuable floral resources to pollinators that are shared with cultivated papaya with little or no cost in terms of heterospecific pollen transfer. Although HP reduced seed production, a reduced number of seeds per se are not negative, given that from an agronomic perspective the number of seeds does not affect the monetary value of the papaya fruit.

Shifts in phenotypes derived from the domestication syndromes impact plant performance but may also affect interactions with other species in the community (e.g. mutualists and antagonists). Moreover, plantations often differ from the natural conditions experienced by the wild relatives of cultivated plants, potentially altering the nature of ecological interactions. However, apart from herbivory, little is known about how domestication and cultivation practices (e.g. insecticide application) can modify multiple ecological interactions simultaneously in wild and domesticated plants. In four sites on the Yucatan Peninsula, we compared the diversity of mutualists (e.g. moths) and antagonists (e.g. viruses) in wild and domesticated plants of papaya. For each individual, we recorded floral visitors and rates of visitation at three time periods during the day. We recorded type and percentage of damage by antagonists in three leaves of all individuals. Finally, we explored if plant sex had an effect on the interaction with floral visitors. The main floral visitors were ants and Trigona species, whereas viruses caused the main type of foliar damage. Wild individuals had a higher diversity and visitation rate of floral visitors, and less foliar damage from antagonists. Wild male individuals were more visited, but we observed a similar amount and diversity of damage in both sexes. The time of day did not have an effect on diversity of floral visitors. Together, cultivation practices and domestication appear to have an effect on the reduction in diversity of floral visitors in domesticated papaya, as well as an increase in foliar damage.
