  • relationship between bagworm pteroma pendula joannis lepidoptera psychidae populations parasitoids and weather parameters in oil palm plantation
    The Journal of Agricultural Science, 2012
    Co-Authors: Nor Ahya Mahadi, R Muhamad, Nur Azura Adam
    Abstract:

    A study on interactions between bagworm Pteroma pendula Joannis (Lepidoptera: Psychidae) populations with parasitoids and weather conditions was carried out at a smallholder oil palm plantation in Hutan Melintang, Perak, Malaysia from January 2011 until December 2011. Samplaing was performed monthly and parasitoids emergence were observed daily. The findings showed that eleven parasitoid species were identified parasitizing the bagworms. The top three parasitoids were Goryphus bunoh (Hymenoptera: Ichneumonidae), Eupelmus catoxanthae (Hymenoptera: Eupelmidae), and Eurytoma sp. (Hymenoptera: Eurytomidae). Bagworms and parasitoids populations were not correlated with weather parameters. The parasitoid populations in this study were relatively low. However, parasitoids were dependent on the bagworms and their populations could have be adversely affected by other factors. The parasitism potential in controlling bagworms need to be investigated further in order to establish their use as biocontrol agents.

  • Morfología del huevo ovárico en calcidoideos (Hymenoptera: Chalcidoidea) parasitoides de avispas de las agallas (Hymenoptera: Cynipidae)
    'Editorial CSIC', 2017
    Co-Authors: Vårdal Hege, Gómez J. F., Nieves-aldrey J. L.
    Abstract:

    [EN] We provide morphological egg data of 26 species of 5 chalcidoid families associated with cynipid galls (Hymenoptera: Cynipidae) from western Palaearctic, including the first egg data for the family Ormyridae. Adult chalcidoid species were reared from galls, and eggs obtained from dissected female ovaries were examined using scanning electron microscopy (SEM). The shape of the eggs varies from oval to elongate and tapered at both ends. Eggs of Eurytomidae as well as some Eulophidae, Eupelmidae and Pteromalidae are equipped with a peduncle at the anterior end. We found a positive correlation between long eggs and long ovipositors and confirmed the expectation that eggs of endoparasitoids are generally shorter and narrower than eggs of ectoparasitoids. We were able to locate the sperm entrance or micropyle at the anterior pole of eggs of several species. It is situated at the anterior end of the egg and at the end of the peduncle when present. In addition, the eggshells of the endoparasitoid Sycophila biguttata (Swederus, 1795) (Hymenoptera: Eurytomidae) and the ectoparasitoid Cecidostiba fungosa (Geoffroy, 1785) (Hymenoptera: Pteromalidae), are for the first time described.[ES] En el presente trabajo se aportan datos morfológicos del huevo de 26 especies del Paleártico occidental pertenecientes a 5 familias de Chalcidoidea asociadas con agallas de cinípidos (Hymenoptera: Cynipidae), incluyendo los primeros datos del huevo de especies de Ormyridae. Los ejemplares adultos de las especies estudiadas fueron obtenidos por emergencia de agallas en laboratorio, los ovarios de las hembras diseccionados para obtener los huevos, que fueron finalmente estudiados utilizando técnicas de microscopía electronica de barrido. La forma de los huevos estudiados varía de ovalada a alargada y ahusada en ambos extremos. Los huevos de Eurytomidae, así como algunos de Eulophidae, Eupelmidae y Pteromalidae están provistos de un pedúnculo en el extremo anterior. Se encontró una correlación positiva entre aquellos huevos elongados y la presencia de ovipositores largos en las hembras, confirmándose también la hipótesis esperada de que los huevos de especies endoparasitoides son generalmente más cortos y estrechos que los de los ectoparasitoides. Por otro lado los estudios de ultraestructura en los huevos de varias especies han permitido la localización del punto de entrada de esperma o micropilo. Este se encuentra situado bien en el extremo anterior del huevo o bien en el extremo del pedúnculo cuando está presente. Además, por primera vez se estudia y se describe la ultraestructura de la cáscara del huevo de la especie endoparasitoide Sycophila biguttata (Swederus, 1795) (Hymenoptera: Eurytomidae) y del ectoparasitoide Cecidostiba fungosa (Geoffroy, 1785) (Hymenoptera: Pteromalidae).We are greatly indebted to the European Union´s Programme Structuring the European Research Area under SYNTHESYS for financing a visit for the senior author to the Museo Nacional de Ciencias Naturales (MNCN) in Madrid.

  • Chalcidoidea (Hymenoptera) obtained from common reed, Phragmites australis (Cav.) Trin. ex Steud. (Poaceae) in Iran with new records and descriptions of two new species
    European Journal of Taxonomy, 2020
    Co-Authors: Hossein Lotfalizadeh, Younes Karimpour, Jean-yves Rasplus
    Abstract:

    Fourteen species of Chalcidoidea (Encyrtidae, Eulophidae, Eupelmidae, Eurytomidae, Pteromalidae and Torymidae) were obtained from the common reed, Phragmites australis (Cav.) Trin. ex Steud. (Poaceae) in the Urmia region, in the northwest of Iran. Among these species, two new species of Pteromalidae are described hereafter: Norbanus persicus Lotfalizadeh & Rasplus sp. nov. and Stenomalina delvarei Lotfalizadeh & Rasplus sp. nov. Anagyrus near alienus Japoshvili, 2002, Asitus sp., Cheiloneurus paralia (Walker, 1837), Echthroplexiella obscura (Hoffer, 1952), Neococcidencyrtus poutiersi (Mercet, 1922) (all Encyrtidae), Aprostocetus orithyia (Walker, 1839) (Eulophidae), Eupelmus phragmitis Erdös, 1955 (Eupelmidae), Aximopsis deserticola (Zerova, 2004) comb. nov., Tetramesa phragmitis (Erdös, 1952) and Tetramesa sp. (all Eurytomidae), Homoporus febriculosus (Girault, 1917) (Pteromalidae) and Torymus arundinis (Walker, 1833) (Torymidae) were also obtained from our laboratory rearing. Nine of these species are recorded for the first time from Iran.

  • sycophila pistacina hymenoptera Eurytomidae a valid species
    European Journal of Entomology, 2008
    Co-Authors: Hosseinali Lotfalizadeh, Gérard Delvare, Jean-yves Rasplus
    Abstract:

    Sycophila pistacina (Rondani), which was previously synonymized with Sycophila biguttata (Swederus), is revalidated. Morphological, morphometric and molecular data confirm its status as a separate species. Diagnostic characters are provided for distinguishing it from S. biguttata. The nomenclature of the S. biguttata complex is updated.

  • phylogenetic analysis of eurytominae chalcidoidea Eurytomidae based on morphological characters
    Zoological Journal of the Linnean Society, 2007
    Co-Authors: Hosseinali Lotfalizadeh, Gérard Delvare, Jean-yves Rasplus
    Abstract:

    A phylogenetic study of the Eurytominae (Hymenoptera: Chalcidoidea) treating 178 taxa and based on 150 morphological characters is given. Several cladograms using the complete species sample, but obtained with different weightings, are presented. Local studies were also carried out to provide possible alternate topologies. The deep nodes of the trees were unstable and were never supported, but most of the superficial nodes were stable and robust. The results therefore provide support for a generic classification of the subfamily. The large genus Eurytoma– which includes about half of the described species of the subfamily – proved to be polyphyletic, and is redefined in a narrowed sense using putative synapomorphies. Bruchophagus and Prodecatoma were similarly redefined. The genera Philolema and Aximopsis are reconsidered and defined in a broader concept. A number of the species presently included in Eurytoma were transferred to these genera. Finally, 22 new generic synonymies are proposed and 33 species are transferred. The study also demonstrates that the Eurytomidae are polyphyletic. The results strongly support a sister-group relationship between the Heimbrinae and the Chalcididae. The Rileyinae consist of two groups of unrelated taxa. A redefinition of the subfamily in a more restricted sense is supported by our results. The remaining group, consisting of the traditional Rileyinae, is included in the subfamily Buresiinae. Considered in this way they comprise the genera Buresium and Macrorileya, the latter being a senior synonym of Archirileya. The Buresiinae appear as the sister group of the Eurytominae. We propose to restrict the family Eurytomidae to these two taxa. This sister-group relationship provides evidence to polarize the biological habits within Eurytominae. The common ancestor of Buresiinae is presumed to parasitize insects (mostly at the egg stage) living in grass stems. © 2007 The Linnean Society of London, Zoological Journal of the Linnean Society, 2007, 151, 441–510.

  • Eurytoma caninae sp. n. (Hymenoptera, Eurytomidae), a common species previously overlooked with E. rosae
    Zootaxa, 2007
    Co-Authors: Hosseinali Lotfalizadeh H., Gérard Delvare, Jean-yves Rasplus
    Abstract:

    We describe a new species, Eurytoma caninae (Hymenoptera, Eurytomidae) from specimens collected in Morocco, France and Iran. The species emerges from galls of Diplolepis spp. (Cynipidae) on Rosa spp. (Rosaceae). It is common and widespread in the West Palearctic Region. It is closely related but morphologically differentiated from Eurytoma rosae Nees. To substantiate our morphological observations, two genes [cytochrome oxidase subunit I (COI) and the internal transcribed spacer region 2 (ITS2)] of several individuals per population were sequenced. Both analyses clearly led to the conclusion that E. caninae and E. rosae are two well-differentiated and previously overlooked species. Morphological diagnostic characters are given to identify both species
