  • (Pueraria Montana Var. Lobata Willd) in North Carolina
    ABSTRACT THORNTON, MELISSA ROSE. Arthopod Fauna Associated With Kudzu (Pueraria montana var. lobata Willd) In North Carolina. (Under the direction of David Orr.) The purpose of this research was to obtain background information to aid the implementation of a biological control program against the weed, kudzu (Pueraria montana var. lobata Willd). This research had several specific objectives that examined: 1) potential insect pollinators and seed production of kudzu in NC; 2) phytophagous insects and insect herbivory of kudzu foliage, seeds, vines and roots in NC; 3) abundance and diversity of foliar, vine, and root feeding insect communities on kudzu in comparison with those found on soybeans, the closest North American relative of kudzu in the United States. Kudzu is pollinated by native and naturalized insects in NC, in a pattern that varies by flower apparency rather than density. Arthropod herbivory by native generalists almost eliminated kudzu seed viability, while a naturalized Asian specialist consumed a nominal proportion of seeds. These data indicate that seed feeding arthropods would be poor candidates for importation biological control. Kudzu and soybeans shared the same foliar feeding insect communities and levels of defoliation, suggesting that foliage feeders are also poor choices for importation. No kudzu vine or root feeding insects or damage were found during the two years of this study, suggesting that future importation biological control research should focus on such feeders from Asia.

  • ARTHROPODA Subphylum Hexapoda Protura, Springtails, Diplura, and Insects

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

  • Sociality in Caterpillars: Investigations Into the Mechanisms Associated with Grouping Behaviour, from Vibroacoustics to Sociogenomics
    Sociality in Caterpillars: Investigations into the Mechanisms Associated with Grouping Behaviour, from Vibroacoustics to Sociogenomics by Chanchal Yadav A thesis submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfillment of the requirements for the degree of Doctorate of Philosophy in Biology Carleton University Ottawa, Ontario © 2020, Chanchal Yadav Abstract Social grouping is widespread among larval insects, particularly in a number of phytophagous larval Lepidoptera (caterpillars). Although the benefits of social grouping are widely recognized, the proximate mechanisms mediating grouping behaviour, such as group formation and maintenance, are poorly understood. My Ph.D. thesis takes a pioneering approach to understanding these mechanisms, specifically, by studying the roles of vibroacoustics and sociogenomics, using the masked birch caterpillar, Drepana arcuata (Lepidoptera: Drepanoidea), as a model. There are two main objectives of my thesis - (i) to test the hypothesis that caterpillars employ plant-borne vibratory signals to recruit conspecifics to social groups; and (ii) to test the hypothesis that differential gene expression is associated with developmental transitions from social to solitary behavioural states. For the first objective, I documented morphological and behavioural changes in the larvae, showing that there are five larval instars, and developmental changes in social and signalling behaviour. Specifically, early instars (I, II) live in small social groups, and late instars (IV, V) live solitarily, with third instars (III) being transitional. Instars I-III generate four signal types (AS, BS, MS, MD), instars IV, V generate three signals (AS, MS, MD). I then used an experimental approach to test if early instars employ vibrations during social recruitment, and found that vibratory signals are used to advertise feeding and silk shelters, leading to recruitment, with higher signalling rates resulting in faster joining times by conspecifics.

  • (Lepidoptera Heliozidae) – a LEAFMINER SPECIES RECORDED on Vitis Vinifera L

FROM SOUTHERN ROMANIA Mirela CEAN Central Phytosanitary Laboratory, 11 Blvd, Voluntari, Ilfov County, 077190, Romania Corresponding author email: [email protected] Abstract Holocacista rivillei Stainton is an European grapevine leafminer distributed in southern Europe and western Asia (Nieukerken et al., 2012). This small butterfly was described from Malta and is considered a minor pest in vineyards being a monophagous species. Another two lepidopteran leafminers occur in European vineyards, both species being originated from North America, i.e. Antispila oinophylla van Nieukerken&Wagner, 2012 (Lepidoptera: Heliozelidae) and Phyllocnistis vitegenella Clemens, 1859 (Lepidoptera:Gracilariidae). Few years ago mines in grapevine leaves were observed in a vineyard located in southern part of the country (Voluntari, Ilfov county). The leaves with symptoms were collected and larvae were reared in laboratory to obtain adults. Identification of the species was done based on their morphological characteristics. Photographs of mines, adults, pupae and genitalia slides are here showed. Preliminary observation on the behavior of this pest are reported. Key words: moth, mines, vineyard, genitalia, Antispila oinophilla, Phyllocnistis vitegenella. INTRODUCTION Family: Antispila (Antispila metallella Denis&Schiffermüller,
