Twenty-three species of insects were observed to be associated with the large chestnut aphid [Lachnus tropicalis Cvander Goot)]. Among these, the number of honeydew feeders was 8 spp.; its natural enemies numbered 8 spp. The most important natural enemies were 3 spp., i.e., Harmonia (Ptychanatis) axyridis (Pallas), Epistrophe balteatus (de Geer) and Pauesia japonica (Ashmead). Ant species probably do not attack aphid parasites, but disturb the searching behavior of the primary parasite.
