Thysanoptera, Phlaeothripinae)

MOUND & ALICE WELLS Australian National Insect Collection CSIRO, PO Box 1700, Canberra, ACT 2601 [email protected] Abstract Drypetothrips korykis gen. et sp.n. is described as inducing leaf-margin galls on a small tree in Australia, Drypetes deplanchei [Putranjivaceae]. This thrips is similar in appearance to the smaller species of the genus Kladothrips that induce galls on Acacia species. The galls are invaded by a phytophagous kleptoparasitic thrips, Pharothrips hynnis gen. et sp.n., females of which have a forked plough-like structure protruding ventrally on the frons that is unique amongst Thysanoptera. Key words: autapomorphy, systematic relationships, leaf-margin galls, Australia Introduction The small tree, Drypetes deplanchei [Putranjivaceae], is widespread across northern Australia as far south as New- castle on the east coast. This tree is sometimes referred to as native holly, because the leaf margins can be sharply dentate, but these margins may also be almost smooth, and a species of thrips has been found inducing rolled margin galls on both leaf forms (Fig. 1). These galls and their thrips have been found at sites near Taree in coastal New South Wales, and also at Mt. Nebo near Brisbane in south-eastern Queensland. -

(Myrsinaceae) in north eastern India (Thysanoptera: Tubulifera: Phlaeothripidae) With 11 figures Heishnam Taptamani, Ramaiyer VAratharajan and A nantanarayanan Raman Summary Biology of the epiphyllous roll-gall-inducing Thlibothrips manipurensis was studied on Ardisia sp. under laboratory conditions. T manipurensis laid eggs linearly along the margins of tender leaves. Eggs hatched in 6.8 d and the larval duration was 3.4 and 8.2 d for larvae I and II, respectively. After 20.2 h as prepupa, T manipurensis grew into pupa; adult emergence occurred in 4 d. Each female laid 34±7 eggs and the mean longevity of the adult was 10.2 d. Increase in thrips numbers correlated with the age of the gall: 15 individ- uals/gall occurred in young (4—10 d) galls, whereas 28 occurred in mature (20 d) galls, and 36 in old (25 d) galls. Male-female ratio in old galls was 1:5. Mature galls included a homogeneous tissue structure, made of 12-15 layers of parenchyma cells with no distinction into spongy and palisade cells. -

Abstract The Tribe Leeuweniini is a group of Old World Phlaeothripinae species that feed and usually induce irregular galls on the leaves of rainforest trees. These thrips all have the last abdominal segment unusually elongate, but this is a variable and homoplastic character state, and the tribe remains ill- defined. Worldwide, 27 species in three genera are now recognised, with five other generic names here included as synonyms of Leeuwenia Karny. From Australia, six species in two genera are recorded here occurring in the eastern rainforests. Four newly described Australian species and their host plants are: Leeuwenia diospyri sp. n. (Diospyros pentamera–Ebenaceae); L. polyosmae sp. n. (Polyosma cunninghamii–Grossulariaceae); L. scolopiae sp. n. (Scolopia braunii–Flacourtiaceae); and L. tetrastigmae sp. n. (Tetrastigma nitens–Vitaceae). The host association of L. convergens Hood is not known, but the sixth species, Neohoodiella jennibeardae Mound and Williams, breeds on two unrelated plants of which the leaves are similar in texture – Ficus coronata (Moraceae) and Rhipogonum elseyanum (Smilacaceae).

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). -
Pp11–32 Of: Evolution of Ecological and Behavioural Diversity: Australian Acacia Thrips As Model Organisms
PART I ECOLOGY AND EVOLUTION OF AUSTRALIAN ACACIA THRIPS SYSTEMATIC FOUNDATIONS In Genesis, light and order were brought forth from chaos, and the world’s biota emerged in six metaphorical ‘days’. The job of an insect systematist is similar but considerably more laborious: from a complex assemblage of forms with sparse biological information attached, to organise, describe and categorise diversity into more or less natural units that share genes. Most biologists only come to appreciate these labours when they are compelled to study a group whose taxonomy is in a chaotic state. Until then, they might view taxonomy as the purview of specialists using arcane knowledge for dubious return on investment, rather than the domain of the only scientists fulfilling God’s instructions to Adam that he name each living thing. This volume provides a comprehensive treatment of Acacia thrips systematics and integrates it with other areas of their biology. As such, the interplay between biology and systematics assumes paramount importance. Non-systematists benefit from systematics in myriad ways. First, without systematics, other biologists remain ignorant not only of what biological units they are studying or seeking to conserve, but what they could choose to study. Indeed, the behavioural studies by Crespi (1992a,b) that led to a resurgence of interest in this group were driven by, and wholly dependent upon, Mound’s (1970, 1971) systematic work. Second, the morphology that most systematists use in species description provides an initial guide to ecological and behavioural phenomena most worthy of study, since morphology sits at the doorstep into natural history, behaviour, ecology and evolution. -

Predation by Insects and Mites
1.2 Predation by insects and mites Maurice W. Sabelis & Paul C.J. van Rijn University of Amsterdam, Section Population Biology, Kruislaan 320, 1098 SM Amsterdam, The Netherlands Predatory arthropods probably play a prominent role in determining the numbers of plant-feeding thrips on plants under natural conditions. Several reviews have been published listing the arthropods observed to feed and reproduce on a diet of thrips. In chronological order the most notable and comprehensive reviews have been presented by Lewis (1973), Ananthakrishnan (1973, 1979, 1984), Ananthakrishnan and Sureshkumar (1985) and Riudavets (1995) (see also general arthropod enemy inventories published by Thompson and Simmonds (1965), Herting and Simmonds (1971) and Fry (1987)). Numerous arthropods, recognised as predators of phytophagous thrips, have proven their capacity to eliminate or suppress thrips populations in greenhouse and field crops of agricultural importance (see chapters 16 and 18 of Lewis, 1997), but a detailed analysis of the relative importance of predators, parasitoids, parasites and pathogens under natural conditions is virtually absent. Such investigations would improve understanding of the mortality factors and selective forces moulding thrips behaviour and life history, and also indicate new directions for biological control of thrips. In particular, such studies may help to elucidate the consequences of introducing different types of biological control agents against different pests and diseases in the same crop, many of which harbour food webs of increasing complexity. There are three major reasons why food web complexity on plants goes beyond one- predator-one-herbivore systems. First, it is the plant that exhibits a bewildering variety of traits that promote or reduce the effectiveness of the predator.
