Data were collected in the field from a common garden experiment conducted in 2011, near the town of Molas (Yucatan, México). These data include the number of fruits, seed predators, and parasitoids recorded per plant, used to analyze and describe insect functional responses. Abbreviated headlines are as follows (from left to right): plant maternal family ("genotype"), fertility treatment (NF = not fertilized, F = fertilized, "treatment"), individual plant sampled ("plant"), number of sampled fruits ("fruit#"), number of fruits with a seed predator or seed predator abundance ("seedpredator#"), and number of attacked fruits by the seed predator with a parasitoid or parasitoid abundance ("parasitoid#"). Data were collected over a two-month period (November-December) in 2011.
