Orius insidiosus (Say) and O. pumilio (Champion) were confirmed to be sympatric in north central Florida as the major predators of the Florida flower thrips, Frankliniella bispinosa (Morgan), on flowers of Queen Anne's lace, Daucus carota L. and false Queen Anne's lace, Ammi majus L. F. bispinosa was the predominant thrips observed on both flowers but colonized D. carota to a greater extent an...
سنکهای Anthocoridae از عوامل کنترل بیولوژیک در اگرواکوسیستمها هستند. ضمن مطالعهای، پراکنش و فراوانی فصلی گونههای جنس Orius روی محصولات زراعی، درختان، گلها و علفهای هرز در استان فارس، طی سالهای 1395- 1397 مورد بررسی قرارگرفت. گونههای Orius albidipennis (Reuter), Orius laticollis discolor (Reuter), Orius laticollis laticollis (Reuter), Orius horvathi (Reuter) , Orius minutus (Linnaeus), Orius...
Biweekly field visits starting from January to the end of April 2011 were conducted to tomato fields (open and plastic houses) heavily infested with the tomato borer Tuta absoluta, in order to survey natural enemies associated with this pest. Three hemipterans were found: Orius albidipennis, Orius sp. (Anthocoridae) and Nesidiocoris tenuis (Miridae). In addition, the parasitic wasp Bracon (Habr...
The cost-reliability of five sampling methods (visual search, drop cloth, beat bucket, shake bucket, and sweep net) was determined for four groups of predatory arthropods on cotton plants in Texas. The beat bucket sample method was the most cost-reliable sampling method for Orius adults, and the beat bucket and drop cloth were the most cost-reliable methods for Orius nymphs. The drop cloth and ...
Pest control in agriculture employs diverse strategies, among which the use of predatory insects has steadily increased. The use of several species within the genus Orius in pest control is widely spread, particularly in Mediterranean Europe. Commercial mass rearing of predatory insects is costly, and research efforts have concentrated on diet manipulation and selective breeding to reduce costs...
The effect of moisture source and diet on the development and reproduction of the pirate bugs, Orius thripoborus (Hesse) and Orius naivashae (Poppius) (Hemiptera: Anthocoridae) was examined in the laboratory. Both species had been collected in and around sugarcane fields in South Africa. Supplementing eggs of the flour moth Ephestia kuehniella (Zeller) (Lepidoptera: Pyralidae) with a green bean...
در مزارع پنبه کشور دشمنان طبیعی متعددی از شکارگرها، انگلها و عوامل بیماریزا وجود دارند که موجب مرگ و میر در جمعیت آفات پنبه میشوند و جمعیت آنها را به تعادل میرسانند. سنهای شکارگر Orius از حشرات مفیدی هستند که میتوانند در کنترل برخی از آفات پنبه بویژه تریپس Thrips tabaci (L.)، شته (Glove.)Aphis gossypii و کنهها موثر باشند. با بازدیدهای هفتگی یک بار از دو مزرعه ثابت پنبه در منطقه گرگان و گ...
Global warming may affect species abundance and distribution, as well as temperature-dependent morphometric traits. In this study, we first used historical data to document changes in Orius (Heteroptera: Anthocoridae) species assemblage and individual morphometric traits over the past seven decades in Israel. We then tested whether these changes could have been temperature driven by searching f...
Data on natural enemies of psyllids are rare and can usually be found in papers about economically significant species. During an investigation of psyllid fauna in Serbia, natural enemies were investigated, too. True bugs were the most numerous among them. From 28 psyllid species, 21 species of true bugs from families Anthocoridae and Miridae were reared. Seven species of Anthocoridae were iden...
طی مطالعه ای سنک های جنس Orius Wolff, 1811 (Hemiptera: Anthocoridae)در استان فارس طی سال های 97-95 مورد بررسی قرار گرفتند. این حشرات مفید هستند و به عنوان اعضای طبیعی فون شکارگران و به عنوان عوامل کنترل بیولوژیک در بسیاری از اگرواکوسیستم ها مورد اهمیت می باشند. نمونه های سنک های جنس Orius از مناطق مختلف استان فارس (در جنوب ایران) جمع آوری شدند و در محلول الکل 75% و گلیسیرین...
