Although the speciescomposition of the parasitoid complex of C. ohridella shows similarities with thesituation found in other closely relatedleafmining moths, it is unlikely that thenaturally occurring chalcidoids will be able toprevent the horse chestnut leafminer from developinging epidemic population densities in thenear future.
Occurrence and phenology of parasitic Chalcidoidea on the horse chestnut leafminer, Cameraria ohridella Deschka & Dimic (Lep., Gracillariidae)
The parasitoid spectrum of the horse chestnut leafminer, Cameraria ohridella, was examined for its adaptation to a newly introduced host with special regard to its possible use in biological pest control.

There is a considerable time lag between the emergence of the parasitoids from the leaflitter in spring and the appearance of suitable host instars in early summer, which may be due to the poor synchronisation between the life cycles of the introduced host and native parasitoid wasps.

The results show that the overall parasitism rate increases as a function of host residence time as well as geographic and climatic factors, altogether reflecting the historic spread of C. ohridella.

It is concluded that the augmentation of tit densities, for example via nesting boxes in chestnut trees, should be considered as a component of an integrated control strategy against the horse chestnut leafminer.
The horse-chestnut leaf miner in Europe - prospects and constraints for biological control.
The horse-chestnut leaf miner, Cameraria ohridella Deschka and Dimic (Lepidoptera: Gracillariidae), is a moth of unknown origin that was first observed in Macedonia in the late 1970s. Since then, it…
Impact of poor host-parasitoid synchronisation on the parasitism of Cameraria ohridella (Lepidoptera: Gracillariidae)
A detailed analysis of the parasitoid community shows that certain species are affected by poor synchronisation, while others are probably limited by ecological parameters, such as a specialisation to foraging in particular strata of vegetation.
Parasitism of Cameraria ohridella (Lepidoptera, Gracillariidae) in natural and artificial horse‐chestnut stands in the Balkans
The horse‐chestnut leafminer, Cameraria ohridella Deschka & Dimic, was discovered during a mass outbreak on planted horse‐ chestnut trees, Aesculus hippocastanum, near Lake Ohrid in Macedonia, and several peculiarities in the leafminers biology and ecology indicate that it may be of exotic origin.
