Turunçgil beyaz kabuklubiti [Parlatoria pergandii Comstock (Hemiptera: Diaspididae)]’nin Doğu Akdeniz Bölgesi turunçgil bahçelerinde parazitoit ve predatör türlerinin belirlenmesi

Abstract

Chaff scale, Parlatoria pergandii Comstock (Hemiptera:Diaspididae) causes damages by sucking trunk, branches, leaves and fruits of its hosts. It causes characteristic green spotting on fruits decreasing its market value, desiccate of leaves and branches and drop of the fruits at high infestations. This study was implemented to detect the parasitoid and predator species of P. pergandii at citrus plantations in eastern Mediterranean region (Adana, Hatay, Mersin and Osmaniye) in 2012-2013. Culturing of shoots and fruits for detecting parasitoids and visual control and strike methods for detecting the predators were applied. As the result of the study, it was detected that Chilocorus bipustulatus (L.) (Coleoptera:Coccinellidae) was the most prevalent and dominant predator of P. pergandii and being detected at all the areas surveyed. The relative abundance was 39.84% and 44.36% in 2012 and 2013, respectively. This species was followed by Rhyzobius lophanthae Blaisdell (Coleoptera:Coccinellidae) and Cybocephalus fodori minor (E.Y.) (Coleoptera:Cybocephalidae). The abundance of Aphytis melinus DeBach (Hymenoptera:Aphelinidae), the dominant parasitoid species, was 43.80% and 47.10% in 2012 and 2013, respectively.

Taxonomy and bioecology of Hemiptera Diaspididae in fruit and landscape trees

“…In the world today, special attention is paid to diaspidological research, the study of the faunal composition of different regions by modern methods, the study of their origin on the basis of the evolution of scales. Work has been developed on the faunistic composition, biology, ecology, taxonomic composition, trophic relationships and phylogeny of diaspidofauna of ecological zones in different regions [3,10,14]. It should be noted that research is needed to identify the fauna of scales in fruit and ornamental plants, their morpho-ecological properties, biological characteristics of some common species, adaptation to living in food plants and the use of integrated control methods [4,7].…”
