Background: Quercus infectoria gall (Oak) has a long history of use as a medicinal plant. Andricus moreae galls arise on young branches of Quercus infectoria as a result of attack by bees.In this research, the antibacterial activity of methanol and acetone extracts of gall (Quercus infectoria) against Staphylococcus aureus, Bacillus cereus, B.subtilis strains was evaluated. Material and met...
بحث و نتیجهگیری : عصاره های متانولی و استونی گال خرنوک بر روی همه باکتری های مورد آزمایش فعالیت ضد باکتریایی نشان دادند. بنابراین، نتایج حاصل از این تحقیق نشان می دهد که عصاره های متانولی و استونی گال خرنوک از بلوط quercus infectoria را می توان به عنوان یک ترکیب ضد باکتریایی در درمان پیشنهاد نمود. مواد و روش ها : این مطالعه تجربی آزمایشگاهی در پاییز 1390 انجام شد. گالها از جنگل های بلوط لرس...
Oak gallwasps (Hymenoptera, Cynipidae, Cynipini) are one of seven major animal taxa that commonly reproduce by cyclical parthenogenesis (CP). A major question in research on CP taxa is the frequency with which lineages lose their sexual generations, and diversify as purely asexual radiations. Most oak gallwasp species are only known from an asexual generation, and secondary loss of sex has been...
Four new species of oak gallwasps, Andricus ahmeti, A. anatolicus, A. bakrachus and A. turcicus (Hymenoptera: Cynipidae: Cynipini) are described from Turkey. All four species are known only from asexual females and induce galls on twigs and young shoots on Q. infectoria, Q. macranthera and Q. petraea. Data on the diagnosis, distribution and biology of the four new species are given. Andricus st...
The last instar nymph of Anacroneuria singularis Righi-Cavallaro & Lecci is described and figured from reared specimens collected in Pará State, Brazil, a new locality record for Brazil. The nymphs of this species differ from other known species by the uniformly dark brown anterior of the head and the ochraceous spots of the pronotum.
We present a densely sampled phylogenomic study of the mulberry tribe (Moreae, Moraceae), an economically important clade with global distribution, revealing multiple losses inflexed stamens, character traditionally used to circumscribe Moreae. Inflexed stamens facilitate ballistic pollen release and are associated wind pollination, results presented here suggest that this state may have evolve...
Gall-inducing insects have especially intimate interactions with their host plants and generally show great specificity with regard to both the host-plant species and the organ (e.g. flower, leaf) galled. However, the relative roles of shifts between host species and between host-plant organs in the diversification of gall-inducers are uncertain. We employ a novel and general maximum-likelihood...
The oak gallwasp Andricus coriarius is distributed across the Western Palaearctic from Morocco to Iran. It belongs to a clade of host-alternating Andricus species that requires host oaks in two sections of Quercus subgenus Quercus to complete its lifecycle, a requirement that has restricted the historic distribution and dispersal of members of this clade. Here we present nuclear and mitochondri...
A total of 57 sairus (Cyphocharax nagelii) from the Peixe River, state of São Paulo, southeastern Brazil, were examined between April 2011 and February 2012. Eleven species of metazoan parasites were collected and identified: Palombitrema triangulum, Curvianchoratus hexacleidus, Curvianchoratus singularis, Sphincterodiplostomum musculosum, Contracaecum sp., Cacatuocotyle paranaensis, Cosmoxynem...
