These data provide counts of Oecophylla smaragdina ants, mealybugs, Amblypelta and Helopeltis bugs, and Rhyparida beetles on a cacao farm where trees in plots were treated or untreated with cacao husks, and trees within plots either had ants present or excluded from trees.
The research evaluates the effects of the predaceous ant Oecophylla smaragdina on three major pests of Australian cacao (Helopeltis spp., Amblypelta spp. and Rhyparida nitida) in an Australian cacao farm, in the presence and absence of cacao fruit husks, a habitat manipulation utilized to provide habitat and food resources for midge (Ceratopogonidae) pollinators. The research also evaluates the effect of O. smaragdina on their potentially plant-damaging, mutualistic mealybug (Pseudococcidae) partners in the presence and absence of cacao fruit husks. The findings suggest that O. smaragdina ants provide pest control services for three major insect pests in Australian cacao farms, however ants generally increase the densities of mealybugs. Furthermore, this pest control may be compatible with habitat manipulations (i.e., the addition of cacao fruit husks) to improve pollinator habitat.
