Asymmetrasca decedens Paoli and Zygina flammigera Fourcroy (Hemiptera: Typhlocybinae), New Pests in Peach and Almond Orchards in Tunisia

摘要

Serious damage caused by cicadellid insects have been observed for a few years in peach and almond orchards in Tunisia. A survey of leafhopper species in the region of Mornag, in the Tunisian North East, shows the presence of two major species feedingon these cultivated trees: Asymmetrasca decedens and Zygina flammigera. The first was previously reported in 2007 on grapevine in the Cap Bon region, but not as stone fruit pest, while the second species is new for the Tunisian fauna. Almond trees seemto be more attacked by cicadellid than peach (67% on almond and 33% on peach). A. decedens is more abundant than Z. flammigera (82.2 and 79.5% of A. decedens and 15.9 and 19.3% of Z. flammigera in peach and almond, respectively).
