Pesticidi i Fitomedicina (Jan 2010)
Predators and Parasitoids of Cacopsylla pyri (L.) (Hemiptera: Psyllidae) in Serbia
Abstract
The presence of C. pyri and its natural enemies was studied in both treated and untreated pear orchards in Serbia from 2005 to 2009. Five parasitoid and 21 predator species were identified as present on a considerable number of sites. The following parasitoid species were found: Prionomitus mitratus (Dalman),Psyllaephagus procerus Marcet,Syrphophagus ariantes (Walker,Syrphophagus taeniatus Förster) and Tamarixia sp. In the study, the species Psyllaephagus procerus,Syrphophagus ariantes and Tamarixia sp. were forthe first time identified as parasitoids of C. pyri and as new species in the Serbian fauna.Among the parasitoids determined, Prionomitus mitratus predominated. Of the predators, the following species in four orders were registered: Dermaptera [Forficula auricularia Linnaeus (Forficulidae)], Heteroptera [Anthocoris nemoralis(Fabricius), Anthocoris nemorum (Linnaeus), Orius (Heterorius) minutus (Linnaeus), Orius (Heterorius) nigerWolff (Anthocoridae), Campylomma verbasci (Mayer-Dür), Deraeocoris (Deraeocoris)ruber(Linnaeus)and Deraeocoris(Knightocarsus)lutescens (Schilling)(Miridae)],Neuroptera[Chrysopa pallens Rambur,Chrysoperla carnea(Stephens),Chrysopa sp.(Chrysopidae)], and Coleoptera [Coccinella septempunctata Linnaeus, Adalia bipunctata Linnaeus, Adalia decempunctata(Linnaeus), Hippodamia tredecimpunctata (Linnaeus),Hippodamia variegata(Goeze),Propylea quatuordecimpunctata (Linnaeus), Calvia (Anisocalvia) quatuordecimguttata(Linnaeus)(Coccinellidae), Cantharis rustica Fallén, Rhagonycha fulva (Scopoli) and Rh. testacea(Linnaeus) (Cantharidae)]. Of the predators determined, 12 species were registered for the first time as predators of C. pyri in Serbia, while C. rustica, Rhagonycha fulva and Rh.testacea have so far been known neither in Serbia nor in the world as predators of pear suckers.
