| Abstract: | The Phenology and natural enemies of the scale insect Kermes echinatus Balachowsky (Hemiptera: Kermesidae), which infests the holly oak Quercus ilex (Fagaceae), were studied between November 2015 and November 2017, in southern Greece (Kalamata, Peloponnese). Kermes echinatus is a univoltine, oviparous and biparental species. It overwinters as 1st instar nymphs, settling on the branches of the trees. The second instar nymphs appear by the middle of April, followed by 3rd instar nymphs until the end of May. The male larvae and pupae were recorded from the end of April to the end of May. Mature females, pre-ovipositing and ovipositing adults, were recorded during May and June. The newly hatched crawlers appeared by the end of June, which remained at this stage, settled on branches during the rest of summer and winter periods till next April. The parasitoid species Metaphycus gennaroi Guerrieri & Noyes and the hyperparasite Cheiloneurus claviger Thomson (Hymenoptera: Encyrtidae) were recorded on the colonies of the scale. The parasitism level of the scale reached to 21%. The predator Chilocorus bipustulatus L. (Coleoptera: Coccinellidae) was also recorded on the colonies of the scale. |
