Investigation of the Biomass and Nutrient Content of Green Manuring Plants as Second Crops in Hungary

The growth, and the development and trends of the nutrient content parameters of three different plant species (Phacelia tanacecifolia,Sinapis alba, Raphanus sativus) grown as secondary crops for green manure, as a function of two different fertiliser doses (0 kg/ha N; 50kg/ha N), was studied under unfavourable site conditions at the Crop Production and Biomass Utilisation Demonstration Centre of theSzent István University, Gödöllő, Hungary. The application of the small, 50 kg/ha dose of nitrogen increased the biomass yield in eachcase, to 2.78-3.11 times that of the control field. The dry matter content of the produce increased only by 2.11-2.66 times, as the watercontent of the green manure plants also increased as a result of the nitrogen supplement. The increased amount of nitrogen boosted theavailability of all of the other macro elements for the plants. In view of the present findings it can be recommend the application of somenitrogen fertiliser in the given site before growing some crop for use as green manure in all cases but where the straw after cereals is left onthe soil surface nitrogen should be applied to alleviate the pentosan effect and to increase the uptake of macro elements

A semantically enriched taxonomic revision of Gryonoides Dodd, 1920 (Hymenoptera, Scelionidae), with a review of the hosts of Teleasinae

Teleasinae are commonly collected scelionids that are the only known egg parasitoids of carabid beetles and therefore play a crucial role in shaping carabid populations in natural and agricultural ecosystems. We review the available host information of Teleasinae, report a new host record, and revise Gryonoides Dodd, 1920, a morphologically distinct teleasine genus. We review the generic concept of Gryonoides and provide diagnoses and descriptions of thirteen Gryonoides species and two varieties: G. glabriceps Dodd, 1920, G. pulchellus Dodd, 1920 (= G. doddi Ogloblin, 1967, syn. nov. and G. pulchricornis Ogloblin, 1967, syn. nov.), G. brasiliensis Masner & Miko, sp. nov., G. flaviclavus Masner & Miko, sp. nov., G. fuscoclavatus Masner & Miko, sp. nov., G. garciai Masner & Miko, sp. nov., G. mexicali Masner & Miko, sp. nov., G. mirabilicornis Masner & Miko, sp. nov., G. obtusus Masner & Miko, sp. nov., G. paraguayensis Masner & Miko, sp. nov., G. rugosus Masner & Miko, sp. nov., G. uruguayensis Masner & Miko, sp. nov. We treat Gryonoides scutellaris Dodd, 1920, as status uncertain. Gryonoides mirabilicornis Masner & Miko, sp. nov. is the only known teleasine with tyloids on two consecutive flagellomeres, a well-known trait of Sparasionidae. An illustrated identification key to species of Gryonoides, a queryable semantic representation of species descriptions using PhenoScript, and a simple approach for making Darwin Core Archive files in taxonomic revisions accessible are provided.Peer reviewe

From Spinning Silk to Spreading Saliva: Mouthpart Remodeling in Manduca sexta (Lepidoptera: Sphingidae)

As a model organism, the tobacco hornworm Manduca sexta (Linnaeus 1763) has contributed much to our knowledge of developmental processes in insects, and major developmental changes between different larval instars are generally well understood. Second and later instars of M. sexta do not produce silk, and their spinneret and accessory labial glands (=Lyonet’s glands), structures thought to be key players in silk production in other lepidopterans, are highly reduced. To our knowledge, mouthparts and labial gland morphology of the silk-producing first instar have never been described. In this study, we compared the mouthpart morphology and transcriptome profile of first and later instars of M. sexta to determine whether the loss of silk production correlates with changes in the structure of the spinneret and the labial glands, and with changes in expression of silk-related genes. We found that the first instar, unlike later instars, has a typical, silk-producing spinneret with a tube-like spigot and well developed Lyonet’s glands. Moreover, three known silk protein genes are highly expressed in the first instar but exhibit little to no expression in the embryo or later instars. Thus, the changes in morphology and gene expression presented here, coinciding with changes in larval behavior from silk production to saliva spreading, further our understanding of the developmental processes underlying this transition in this model organism

A hymenopterists' guide to the hymenoptera anatomy ontology: utility, clarification, and future directions

Hymenoptera exhibit an incredible diversity of phenotypes, the result of ~240 million years of evolution and the primary subject of more than 250 years of research. Here we describe the history, development, and utility of the Hymenoptera Anatomy Ontology (HAO) and its associated applications. These resourc¬es are designed to facilitate accessible and extensible research on hymenopteran phenotypes. Outreach with the hymenopterist community is of utmost importance to the HAO project, and this paper is a direct response to questions that arose from project workshops. In a concerted attempt to surmount barriers of understanding, especially regarding the format, utility, and development of the HAO, we discuss the roles of homology, “preferred terms”, and “structural equivalency”. We also outline the use of Universal Resource Identifiers (URIs) and posit that they are a key element necessary for increasing the objectivity and repeatability of science that references hymenopteran anatomy. Pragmatically, we detail a mechanism (the “URI table”) by which authors can use URIs to link their published text to the HAO, and we describe an associated tool (the “Analyzer”) to derive these tables. These tools, and others, are available through the HAO Portal website (http://portal.hymao.org). We conclude by discussing the future of the HAO with respect to digital publication, cross-taxon ontology alignment, the advent of semantic phenotypes, and community-based curation.Katja C.
