  • ARTHROPODA Subphylum Hexapoda Protura, Springtails, Diplura, and Insects
    NINE Phylum ARTHROPODA SUBPHYLUM HEXAPODA Protura, springtails, Diplura, and insects ROD P. MACFARLANE, PETER A. MADDISON, IAN G. ANDREW, JOCELYN A. BERRY, PETER M. JOHNS, ROBERT J. B.

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).

  • Thrips on Oat in Western Romania
    Research Journal of Agricultural Science, 50 (4), 2018 THRIPS ON OAT IN WESTERN ROMANIA F. PARNEA, Ana – Maria VÎRTEIU1*, Ioana GROZEA1 1Department of Biology and Plant Protection, Banat’s University of Agricultural Sciences and Veterinary Medicine "King Michael I of Romania" from Timisoara * Corresponding author: [email protected] Abstract. The oat crop in western Romania has begun to occupy increasingly large areas, as the fertile soil in this area along with a modern, properly applied technology has allowed farmers to obtain high yields. Thus, in order to develop an adequate pest control strategy for oat crops, it is necessary to understand the particularities related to phenology, distribution and life cycle of major pests of this crop. Among insects present in oat crops, thrips are between those that cause significant yields losses. Regarding biology, ecology, and control of thrips, a significant number of works have been published so far, but the changing climate conditions with arid tendencies make this knowledge to be far from satisfied. In Romania, research on this group of insects were numerous, being localized mainly on the species present in economically important cereal crops. In this context, the authors have recently conducted a series of research on the taxonomy of thrips species present in this crop. The experimental plots were placed in the western part of Romania, near the village of Sag, the experience being carried out during 2017 - 2018. In the investigated period, 474 specimens were collected from the oat crop, belonging to 8 species of thrips. In each experimental variant Limothrips cerealium Holiday and Limothrips denticornis Holiday were the dominant species.

  • 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.

Chirothrips maximi Ananthakrishnan and Limothrips cerealium Haliday are recorded from Iran for the first time. A checklist is provided of Thripinae recorded from this country. Keywords Thysanoptera, Thripinae, identification, Iran Introduction The family Thripidae (Thysanoptera: Terebrantia) at present comprises more than 2000 described species, which are classified into four subfamilies, Thripinae, Dendro- thripinae, Sericothripinae, and Panchaetothripinae (Bhatti 1989). The present study follows the interpretation of Thripinae in this classification. Another recent classifica- tion of Terebrantia (Bhatti 2006) recognizes three superfamilies and 12 families for taxa included in the four subfamilies of Thripidae, and the taxa of the earlier subfam- ily Thripinae are included in three families (Chirothripidae, Projectothripidae, and Thripidae) (Bhatti 2006).

A. MOUND1 & Y. F. NG2 1c/- CSIRO Entomology, Canberra, ACT 2601, Australia. E-mail [email protected] 2Centre for Insect Systematics, Universiti Kebangsaan Malaysia, 43600 Bangi, Selangor, Malaysia. E-mail: [email protected] Abstract An illustrated key is provided for the identification of 65 genera of Thripinae from South East Asia. Wherever possible notes are given on the host-plant associations and geographical distributions, and suggestions made concerning phylogenetic relationships. The combination Taeniothrips euophthalmos Moulton is re-established. Key words: Thysanoptera, Thripinae, Asia, genus, identification Introduction South East Asia is one of the most biologically diverse areas on earth, but there are major impediments for young Asian biologists wishing to develop an understanding of the rich fauna of their countries. The lack of identification keys to the Asian insect fauna is critical, and the library resources, also the collections of identified reference specimens, are insufficient to help a student to develop an extensive knowledge of any particular group. Electronic copying can be expected to make scientific literature more widely available, progressively. Moreover, collaborative data-basing between institutes holding extensive collections of specimens has the potential, in time, to enrich the available research base. But the development of identification keys often requires collaboration between local workers and international specialists who have knowledge of a wider fauna. The identification key presented here was developed in this way: to fill a mutual requirement; it is needed by Malaysian biologists to facilitate identification of the thrips on their crops and in their forests, and it is needed in other countries by quarantine entomologists for routine interception work.

  • Chapter 9. Arthropods of Cereal Crops in Canadian Grasslands
    217 Chapter 9 Arthropods of Cereal Crops in Canadian Grasslands John Gavloski Manitoba Agriculture, Food and Rural Initiatives, Crops Knowledge Centre, 65 3rd Ave. NE, Carman, Manitoba, Canada R0G 0J0 Scott Meers Alberta Agriculture and Rural Development, 301 Horticultural Station Road East, S.S. #4, Brooks, Alberta, Canada T1R 1E6 Abstract. Cereal crops are a major aspect of the Canadian prairie landscape. This chapter focuses on insects of small grain cereals (wheat, oats, barley, and rye), but not on larger grains such as corn, which are less abundant on the Canadian prairies. Settlement of the Canadian prairies resulted in the replacement of vast amounts of native prairie plants with cereal crops. Many native insects adapted and flourished in this new habitat. Many alien insect species have also been accidentally introduced and are now pests of cereal crops. Other insects have been purposely introduced to regulate the populations of insect pests of cereal crops. Insect species are presented in feeding guilds in this chapter. Insects within a feeding guild feed on the same or a similar resource and may at times compete for this resource. Changes in cropping practices and varieties can also have an impact on the insect communities on cereal crops. Such interactions will also be described. Résumé. Les cultures de céréales occupent une place très importante dans le paysage des prairies canadiennes. Le présent chapitre porte principalement sur les insectes qui s’attaquent aux petites céréales (blé, avoine, orge et seigle), et non sur ceux qui se nourrissent de céréales à graines plus grosses — par exemple, le maïs — moins abondantes dans les prairies canadiennes.
