چکیده

تریپس افرا، (Taeniothrips inconsequens (Uzel) (Thysanoptera: Thripidae یکی از تریپس­ های مهم گیاه­ خوار روی درختان افرای جنگل­ های زاگرس در استان ایلام می ­باشد که به تازگی باعث ایجاد خسارت روی این درختان شده است. در این تحقیق، دشمنان طبیعی این تریپس با نمونه ­برداری­ های ماهیانه در سال 1394 از درختان افرای کوه­ های گچان و مانشت جمع­ آوری و شناسایی شد. نتایج حاصل نشان داد که دشمنان طبیعی شامل یک زنبور پارازیتوئید لارو تریپس (Ceranisus menes (Walker از خانواده Eulophidae، و 12 حشره و کنه شکارگر از خانواده­ های زیر بود: خانواده ­ی Aeolothripidae] Aeolothrips intermedius Bagnall]، خانواده­ ی Thripidae [Scolothrips longicornisPriesner]، خانواده­ ی Phlaeothripidae] Haplothrips flavitibia Williams, Haplothrips globiceps Bagnall]، خانواده ­ی Anthocoridae] Anthocoris pilosus (Jakovlev), Orius laevigatus (Fieber), Orius niger (Wolff, 1811]، خانواده­ ی (Miridae] Deraeocoris pallens (Reuter]، خانواده ­ی (.Nabidae] Nabis ferus (L]، خانواده ­یCoccinellidae] Coccinella septempunctata[ (L]، خانواده­ ی (Chrysopidae] Chrysoperla carnea (Stephens]، و خانواده ­ی (.Anystidae]Anystis baccarum (L]. مجموع شکارگرها در طول دوره زیستی تریپس افرا روی درختان افرا حضور داشتند ولی جمعیت تریپس­ شکارگر A. intermedius  و سن­ های جنس Orius بالاتر از دیگر دشمنان طبیعی بود.

چکیده [English]

The pear thrips, Taeniothrips inconsequens (Uzel) (Thysanoptera: Thripidae) is one of the most important pests, that is recently causes damages to Montpellier maple trees in Zagros forests, Ilam province (western Iran). In this study, the natural enemies of maple thrips were collected and identified by monthly sampling of thrips from Gachan and Manesht Mountains, in year 2015. Results indicated that natural enemies included one larval parasitoid, Ceranisus menes (Walker) (Hymenoptera: Eulophidae), and 12 insects and mite predator species belonging to the nine following families: Aeolothripidae [Aeolothrips intermedius Bagnall], Thripidae [Scolothrips longicornisPriesner], Phlaeothripidae [Haplothrips flavitibia Williams, Haplothrips globiceps Bagnall], Anthocoridae [Anthocoris pilosus (Jakovlev), Orius laevigatus (Fieber), Orius niger (Wolff, 1811)], Miridae [Deraeocoris pallens (Reuter)], Nabidae [Nabis ferus (L.)], Coccinellidae [Coccinellaseptempunctata (L.)], Chrysopidae [Chrysoperla carnea (Stephens)], and Anystidae [Anystis baccarum (L.)]. All predators collected in this study were on maple trees along with maple thrips, among them A. intermedius and Orius spp. had higher population densities in contrast to other natural enemies.
