Produce coffee in shaded plantations
A site comparison study in 2016 in five coffee plantations in Veracruz, Mexico (Sosa-Aranda et al. 2018) found that shaded coffee plantations had a higher abundance and species richness of caterpillars than a sun-grown monoculture plantation. On four polyculture and shaded monoculture coffee plantations, the abundance (124–212 individuals) and species richness (83–129 species) of caterpillars was higher than in a sun-grown coffee monoculture (abundance: 47 individuals; richness: 46 species). In addition, the amount of damage found on coffee leaves was not related to either caterpillar abundance or species richness (data not presented). The management intensity of five coffee plantations was measured based on 10 vegetation characteristics (including canopy cover, epiphyte cover, area of shade trees and presence of herbs) and the frequency of six external inputs (fertilizers, insecticides, herbicides, fungicides, irrigation and ploughing). In July, September and December 2016, all caterpillars were collected by hand from all plants along three 30 × 2-m transects in the centre of each plantation, and reared to adults for species identification.

Reduce fertilizer, pesticide or herbicide use generally
A site comparison study in 2016 in five coffee plantations in Veracruz, Mexico (Sosa-Aranda et al. 2018) found that coffee plantations managed less intensively, including with fewer chemical inputs, supported more caterpillars than more intensively managed plantations. On the least intensively managed plantation, both the abundance (212 individuals) and species richness (129 species) of caterpillars was higher than on the most intensively managed plantation (abundance: 47 individuals; richness: 46 species). Both abundance and species richness on the other three plantations were intermediate. In addition, the amount of damage found on coffee leaves was not related to either caterpillar abundance or species richness (data not presented). The management intensity of five coffee plantations was measured based on 10 vegetation characteristics (including canopy cover, epiphyte cover, area of shade trees and presence of herbs) and the frequency of six external inputs (fertilizers, insecticides, herbicides, fungicides, irrigation and ploughing). In July, September and December 2016, all caterpillars were collected by hand from all plants along three 30 × 2-m transects in the centre of each plantation, and reared to adults for species identification.
