Predation of Cabbage Pests PREDATION OF CABBAGE PESTS: A COMBINED ECOLOGICAL AND MOLECULAR APPROACH Rini Murtiningsih A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2014 School of Biological Sciences Abstract Plutella xylostella L (Lepidoptera: Plutellidae) and Crocidolomia pavonana F (Lepidoptera: Crambidae) are serious pests of Brassica crops in the highlands of West Java, Indonesia, where they co-occur, and in Southeast Queensland, Australia where C. pavonana is a serious pest early in the crop season (February–May) and P. xylostella is a pest later in the year (June-November). Introductions of parasitoids of P. xylostella, especially Diadegma semiclausum Hellén (Hymenoptera: Ichneumonidae), have had considerable success in both countries, but no effective larval or pupal parasitoids of C. pavonana are known. The use of insecticides to manage C. pavonana disrupts P. xylostella parasitoids, leading to pest outbreaks. Thus, an integrated pest management (IPM) strategy, that takes account of both pests, is needed in both regions. Although P. xylostella parasitoids have been the centre of much research over the past 50-60 years, the impact of predatory arthropods on pest populations has received much less attention. Similarly, little is known about the impact of predators on C. pavonana populations and it appears to be attacked by a particularly sparse parasitoid fauna. In recent years, considerable advances have been made in the development of DNA-based molecular techniques to detect the remains of insect prey within the guts of predatory arthropods. However, the methods have rarely been applied in conjunction with field experiments that measure the impact of natural enemies on pest/ prey populations. In this research, field studies used a combination of ecological (natural enemy exclusion experiments and the construction of life tables) and DNA-based molecular methods to quantify the impact of predatory arthropods on P. xylostella and C. pavonana populations and to identify the most important predatory groups preying on these insect pests in the different agro-ecosystems of Queensland and West Java. The specificity of previously designed primer sequences for P. xylostella, C. pavonana and Pieris rapae L. (Lepidoptera: Pieridae) mtCO1 DNA was confirmed by testing them against a wide range of herbivores and predatory arthropods collected from the field in both West Java and Queensland. Based on field studies, key groups of predators were selected to determine the detectability half-life of target P. xylostella and C. pavonana mtCO1 DNA in their guts following consumption of single prey items. For the P. xylostella mtCO1 DNA, when tested at 25 °C the detectability half-life (DHL) was lowest in Clubionidae (18 h) < Linyphiidae (42 h) ≤ Lycosidae (61 h) < Theridiidae (135 h). Similarly when tested at this temperature, the DHL for C. pavonana mtCO1 DNA was lower in Lycosidae (93 h) than in Theridiidae (193 h). Despite having a longer base pair sequence, the target C. pavonana fragment (276 bp) typically persisted for longer in the guts of predators than ii the P. xylostella fragment (165 bp) and in Theridiidae, the DHL of target DNA of both species decreased with increasing temperature when tested at 20, 25 and 30 °C Field studies in Australia showed that the impact of the endemic natural enemy complex could suppress P. xylostella and C. pavonana populations, but that predators had a greater impact on P. xylostella populations than on C. pavonana populations. Based on their relative abundance, the proportion sampled that tested positive for target prey DNA and the DHL for target prey DNA in gut-contents analysis, Clubionidae and Linyphiidae were identified as the major predators of P. xylostella, although Lycosidae and Theridiidae, and probably the coccinelid H. varieagata, also contributed to P. xylostella suppression. The endolarval parasitoid D. semiclausum also contributed significantly to P. xylostella mortality but overall, the combined action of predators caused greater mortality. Similar analysis identified Araneidae, Clubionidae, Lycosidae, Linyphiidae, Oxyopidae and Salticidae as predators of C. pavonana, although more limited determination of DHL for C. pavonana DNA for these groups makes it difficult to rank predators in order of importance. In Queensland, C. pavonana did not suffer significant mortality due to parasitoids. Studies in West Java investigated the impact of natural enemies on P. xylostella and C. pavonana populations simultaneously. The endemic predator complex and D. semiclausum suppressed P. xylostella populations, but predators had a greater impact than the parasitoid. Crocidolomia pavonana was not attacked by parasitoids in West Java and although predators could reduce the pest population, they had a lower and more variable effect on C. pavonana than on P. xylostella. Most foliar dwelling spiders (Araneidae, Clubionidae, Gnaphosidae, Linyphiidae, Salticidae and Tetragnathidae) consumed P. xylostella but only a small number of Araneidae and Gnaphosidae tested positive for C. pavonana DNA. When sampled at the soil surface, Gnaphosidae and Lycosidae were positive for C. pavonana DNA and only Lycosidae were positive for P. xylostella DNA. The predatory insect fauna was more diverse in West Java than in Queensland and many groups, but particularly larval Syrphidae, adult and larval Coccinellidae and Staphylinidae tested positive for both pests. iii Declaration by author This thesis is composed of my original work, and contains no material previously published or written by another person except where due reference has been made in the text.

In total, the character matrix includes 47 taxa: 35 linyphiids representing the currently used subfamilies of Linyphiidae (Stemonyphantinae, Mynogleninae, Erigoninae, and Linyphiinae (Micronetini plus Linyphiini)) and 12 outgroup species representing nine araneoid families (Pimoidae, Theridiidae, Nesticidae, Synotaxidae, Cyatholipidae, Mysmenidae, Theridiosomatidae, Tetragnathidae, and Araneidae). The morphological characters include those used in recent studies of linyphiid phylogenetics, covering both genitalic and somatic morphology. Different sequence alignments and analytical methods produce different cladistic hypotheses. Lack of congruence among different analyses is, in part, due to the shifting placement of Labulla, Pityohyphantes,

Most of the existing taxonomic work on Australian linyphiids consists of isolated species descriptions (e.g., Rainbow 1912) or at most are based on small number of species also described outside a revisionary context (e.g., Wunderlich 1976) (but see van Helsdingen 1972 for a revision of the Australian species of the genera Laperousea Dalmas, 1917 and Laetesia Simon, 1908). Microctenonyx subitaneus (O. P.-Cambridge, 1875) is a Holarctic erigonine (Linyphiidae) which has been introduced in many parts of the world, including Australia (Brennan 2004). In this paper we report a new junior synonym of Microctenonyx subitaneus described by Butler (1932) under the name Alaxchelicera ordinaria Butler, 1932. In 1932 L.S.G. Butler, a Melbourne-based arachnologist, published a paper in which he described six new spider genera from Victoria and New South Wales, all of them monotypic. Three of these new genera (Microlinypheus, Plectochetos and Alaxchelicera) he placed in the family Linyphiidae, the remaining three (Platycephala, Eterosonycha and Perissopmeros) were placed in Zodariidae.

  • Spiders (Aranei) of Moist Meadows on the Mazovian Lowland
    POLISH ACADEMY OF SCIENCES • INSTITUTE OF ZOOLOGY MEMORABILIA ZOOLOGICA MEMORABILIA ZOOL. 43 37-60 1989 WOJCIECH STARĘGA SPIDERS (ARANEI) OF MOIST MEADOWS ON THE MAZOVIAN LOWLAND ABSTRACT The spider material from 4 localities of Arrhenatheretum medioeuropaeum and 2 comparative sites in Warsaw surroundings has been elaborated — 93 species in the epigeon and 77 species in the epiphyton (altogether 129). A typical character of epigeic araneofauna of Arrhenatheretum medioeuropaeum is the dominance of Pardosa palustris and Pachygnatha degeeri at a considerable percentage of Oedothorax fuscus, Erigone atra, E. dentipalpis, Pardosa pullata and P. prativaga. It has been proved that the life cycle of the most abundant and active species — P. palustris — affects mainly the periodical changes in dominance structure. Three species new to Poland have been discovered: Euophrys aperta, Agyneta decora and Pocadicnemis juncea; 2 species not included yet in the list of Polish fauna : Philodromus cespitum and Walckenaeeria alticeps and 2 species new to Mazovia: Agyneta cauta and Dismodicus bifrons and several species rarely caught in Poland. Apart from forests and arable lands, various types of meadows are the main component of the landscape of Polish Lowland. The ryegrass meadow ( Arrhena­ theretum medioeuropaeum) used both as a source of quality dry fodder and a pasture is one of the economically most important meadows. However, it covers rather small areas, because this association (result of man’s interference with natural succession of moist forests) grows on soils very good for cultivation and therefore more frequently used for this purpose. Although the meadows are easily available for investigations, their araneofauna has not been satisfactorily examined yet.

    Motuora Native Species Restoration Plan JUNE 2007 Motuora Native Species Restoration Plan By Robin Gardner-Gee, Sharen Graham, Richard Griffiths, Melinda Habgood, Shelley Heiss Dunlop and Helen Lindsay MOTUORA RESTORATION SOCIETY (INC) PO Box 100-132, NSMC, Auckland. Foreward Deciding to write a Restoration Plan for Motuora was a huge undertaking for a voluntary group, especially since most of those whose help we needed already had busy lives. The project required surveys on the island to establish what plants and animals were already there, followed by much discussion and the writing of the various sections. These sections then had to be edited to make a unified whole. This document could not have been written without the enthusiasm, knowledge, and commitment of a group of keen environmentalists who put in long hours to produce the Restoration Plan. The Motuora Restoration Society thanks the many people and organizations who have provided information, advice and comment on this document. Particular thanks to: Robin Gardner-Gee for her invertebrate knowledge Sharen Graham for her bird knowledge Richard Griffiths for pulling the document together to present an overview of the whole island ecology Melinda Habgood for her reptile knowledge Shelley Heiss-Dunlop for her plant knowledge Helen Lindsay for her input into the plant section and for co-ordinating the project especially in the beginning Te Ngahere Native Forest Management for supporting this project Department of Conservation staff for support and encouragement. The Motuora Restoration Society thanks you all for your generosity in sharing your learning and experience.

  • An Account of Money Spiders from Down Under (Araneida, Linyphiidae)
    AN ACCOUNT OF MONEY SPIDERS FROM DOWN UNDER (ARANEIDA, LINYPHIIDAE) by P.J. VAN HELSDINGEN Rijksmuseum van Natuurlijke Historie, Leiden With 24 figures The Australian and New Zealand regions so far were left out of considera• tion when studying the Linyphiidae (Linyphiinae) on a world-wide basis. When revising the genus Linyphia it appeared that a fair number of species had been described from these regions; but it also became very clear, by a superficial investigation, that these species were so completely different from our European concept of Linyphia and related genera, that they were best put aside then with a view to paying more attention to that part of the world at a later time. A small collection of Linyphiidae from Australian caves, recently received from Mrs. Barbara York Main, Nedlands, Western Australia, offered an excellent opportunity to become better acquainted with the interesting fauna of this continent and the adjacent regions. Together with a number of speci• mens gathered in the course of years from different museum collections this formed a small but useful basis to start from. The specimens received from Australia and from other musea were used as nuclei of investigation into the literature of this region. Of the formerly described species only those were re-investigated that were considered to be closely related to the species already at hand. The number of species of Linyphiidae that have been described from Australia is very small, only nine. Four more are known from Tasmania. New Zealand (Auckland Island, Campbell Island, and Antipodes Island included, each with one species) is by far the richest, as far as our knowledge of this family goes at present, with 25 species, two of which are more widely distributed over the world.

This began with preparation of a management plan as an honours project when such a document was a real novelty. He had the rare opportunity to create national parks, working with the Land Conservation Council in Victoria where he defined the boundaries and gave names to proposed new national parks, including Croajingalong, Snowy River and Tingaringy, which the Government adopted. Dr Coyne joined the Australian National Parks and Wildlife Service in its early days and spent four years establishing the Service’s office and operations on Norfolk Island, and introducing the concept of environmental management to the island’s community and government (which led to the creation of the Norfolk Island National Park). He then headed the ANPWS Park Planning Section, personally preparing the management plan for Kakadu National Park and having responsibility for preparation of other plans ranging from central Australia (Uluru–Kata Tjuta) to marine national nature reserves in the Coral and Timor Seas, and park plans for Australia’s remote Indian Ocean Territories. During this time he also developed the legislation and lease to enable transfer of Uluru to its traditional Aboriginal owners and its lease back to the Director of National Parks and Wildlife for continuing use as a national park.
