Hymenoptera parasitoids of Megaloptera, particularly the family Corydalidae, are rarely found. Ooencyrtus Ashmead is a genus that attacks eggs of many orders of Insecta, including Megaloptera. Here, three species, O. longicauda sp. n., O. noyesi sp. n. and O. protohermeasis sp. n. are described. Two of them, O. longicauda and O. protohermesis were reared from eggs of corydalids (Megaloptera: Co...
Spotted Lanternfly, Lycorma delicatula (White) is a recently introduced pest of Tree-of-Heaven, Ailanthus altissima (Mill.) Swingle in North America. Natural enemy surveys for this pest in Pennsylvania in 2016 recovered an encyrtid egg parasitoid from both field collections and laboratory rearing of field-collected L. delicatula egg masses. Both molecular and morphological data confirm that the...
Two new species, Ooencyrtus alrake Hayat, sp. nov. and Syrphophagus wayanadensis Hayat, sp. nov. (Hymenoptera: Chalcidoidea: Encyrtidae), are described from material collected in Kerala State (India) from Trioza jambolanae Crawford (Hemiptera: Psylloidea: Triozidae), a leaf gall-inducer on species of Syzygium (Myrtaceae). Two species, Psyllaephagus garuga S. Singh and P. phacopteron S. Singh, b...
This is the first major contribution to the fauna of the family Encyrtidae (Hymenoptera: Chalcidoidea) of the Kingdom of Saudi Arabia. The following new genus and 15 new species are described: Anagyrus azolus Hayat, sp. nov., A. raidahensis Hayat, sp. nov., Arabencyrtus qahtanii Hayat, gen. et sp. nov., Cerchysiella arabia Hayat, sp. nov., C. azeeza Hayat, sp. nov., Cheiloneurus arabiacus Hayat...
A new genus of Encyrtidae (Hymenoptera: Chalcidoidea), Noyesencyrtus Singh gen. nov. (type species N. brachyoculus Singh sp. nov.), associated with insects inhabiting fruiting bodies of wood-decaying fungi, and two new species, Psyllaephagus kundapurensis Singh sp. nov. and Ooencyrtus hayatii Singh sp. nov., are described from the Western Ghats of Karnataka, India.
Four new brachypterous species of Encyrtidae (Hymenoptera: Chalcidoidea) are described. These are: Astymachus eximius Hayat, sp. nov., Ixodiphagus aethes Hayat, sp. nov., Monstranusia brachyptera Hayat, sp. nov., Ooencyrtus notialis Hayat, sp. nov. Brachyptery in the genera Astymachus Howard and Monstranusia Trjapitzin is reported for the first time.
We investigated intraguild interactions between two egg parasitoids of Nezara viridula (L.) (Heteroptera: Pentatomidae), Ooencyrtus telenomicida (Vassiliev) (Hymenoptera: Encyrtidae) and Trissolcus basalis (Wollaston) (Hymenoptera: Platygastridae), as the former has the potential to be a facultative hyperparasitoid of the latter. We assessed the suitability of N. viridula eggs for the developme...
زنبور ooencyrtus fecundus ferriere &vogele (hymenoptera: encyrtidae) از جمله پارازیتوییدهای تجمعی تخم سن گندم است که قدرت سوپرپارازیتیسم دارد. سوپرپارازیتیسم تأثیرات چشمگیری روی شایستگی و ظرفیت تولید مثلی، قدرت رقابت و جثة حشرات کامل پارازیتوییدهای جمعی دارد. در این بررسی اثر سوپرپارازیتیسم و شدت آن (ماده های تک قلو، دوقلو، سه قلو و چهارقلو) روی ویژگی های زیستی زنبور o. fecundus در شرایط آز...
The increased use of molecular tools for species identification in recent decades revealed that each of many apparently generalist parasitoids are actually a complex of morphologically similar congeners, most of which have a rather narrow host range. Ooencyrtus pityocampae (OP), an important egg parasitoid of the pine processionary moth (PPM), is considered a generalist parasitoid. OP emerges f...
Nezara viridula L. and Euschistus servus (Say) are the predominant species of phytophagous stink bugs on corn, Zea mays L., in Georgia. Oebalus pugnax pugnax (F.) occurs in relatively low numbers, and the predatory stink bug Podisus maculiventris (Say) is commonly found. Limited information is available on natural biological control of these four stink bug species in Georgia corn fields; there...
