Aposematism, true bugs, Heteroptera, avian predators, mimetic complex Abstract. True bugs are generally considered to be well protected against bird predation. Sympatric species that have similar warning coloration are supposed to form a functional Müllerian mimetic complex avoided by visually oriented avian predators. We have tested whether these assumptions hold true for four species of European red-and-black heteropterans, viz. Pyrrhocoris apterus, Lygaeus equestris, Spilostethus saxatilis, and Graphosoma lineatum. We found that individual species of passerine birds differ in their responses towards particular bug species. Great tits (Parus major) avoided all of them on sight, robins (Erithacus rubecula) and yellowhammers (Emberiza citrinella) discriminated among them and attacked bugs of some species with higher probability than oth- ers, and blackbirds (Turdus merula) frequently attacked bugs of all the tested species. Different predators thus perceive aposematic prey differently, and the extent of Batesian-Müllerian mimetic complexes and relations among the species involved is predator dependent. INTRODUCTION some cases their very existence are often suspect and Unpalatable animals usually use warning signals to dis- mostly lack experimental evidence. Only few comparative courage predators from attacking them.

  • Meiotic Studies in Lygaeus Alboornatus Blanchard 1852 (Heteroptera, Lygaeidae, Lygaeinae)

Larramendy1' * 1 Laboratorio de Citogenètica y Cátedra de Citología, Facultad de Ciencias Naturales y Museo, Universidad Nacional de La Plata, Calle 37 Nro. 668 7mo “B", 1900 La Plata, Argentina. 2 Departamento de Ciencias Biológicas, Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, Buenos Aires, Argentina. Abstract - The subfamily Lygaeinae comprises 58 genera with about 500 species distributed world-wide. Despite the great biodiversity of the taxon, cytogenetic data of the group is scarce. To date, only 26 species belonging to 12 genera have been cytogenetically described. As it is the rule for the order Heteroptera, all the species possess holokinetic chromosomes, and a pre-reductional type of meiosis, namely at anaphase I the autosomal bivalents divide reductionally while the sex chromosomes are achiasmatic and divide equationally. Available data reveal that all the Lygaeinae are characterised by a modal diploid number of 14 and an XY/XX sex chromosome determining system. In the present study the male mei­ otic development of Lygaeus alboornatus from Argentina is analysed. The results demonstrate that the species, though sharing the basic chromosomal features from Lygaeinae, has a diploid number of 12 (10+XY), being this chromosome number the lowest reported so far for the subfamily. Key words: Heteroptera, Lygaeinae, Lygaeus alboornatus, Meiosis, Holokinetic chromosomes. INTRODUCTION valid species are distributed in all faunal regions both in the Old and in the New Worlds (SCHUH Members of the large and diverse family Ly­ and SLATER 1995).

Analyses conducted using repetitive DNAs have contributed to better understanding the chromosome structure and evolution of several species of insects. There are few data on the organization, localization, and evolutionary behavior of repetitive DNA in the family Lygaeidae, especially in Brazilian species. To elucidate the physical mapping and evolutionary events that involve these sequences, we cytogenetically analyzed three species of Lygaeidae and found 2n (♂) = 18 (16 + XY) for Oncopeltus femoralis; 2n (♂) = 14 (12 + XY) for Ochrimnus sagax; and 2n (♂) = 12 (10 + XY) for Lygaeus peruvianus.

  • Differences Between Two Co-Occurring Aposematic Lygaeinae Bugs
    Ecological Entomology (2000) 25, 220±225 Effects of food plant and group size on predator defence: differences between two co-occurring aposematic Lygaeinae bugs BIRGITTA S. TULLBERG,1 GABRIELLA GAMBERALE- 1 2 STILLE andCHRISTER SOLBRECK 1Department of Zoology, University of Stockholm and 2Department of Entomology, Swedish University of Agricultural Sciences, Uppsala, Sweden Abstract. 1. The role of food plant and aggregation on the defensive properties of two aposematic sympatrically occurring seed bugs, Tropidothorax leucopterus and Lygaeus equestris (Lygaeinae, Heteroptera), was investigated. Larvae reared on seeds either of their natural host plant Vincetoxicum hirundinaria (Asclepiadaceae) or of sun¯ower Helianthus annuus were subjected to predation by chicks. 2. The two species differ in their dependency on the host for their defence. Lygaeus equestris was better defended on its natural host plant than on the alternative food, as indicated by fewer attacks, lower mortality, and predator avoidance after experience. No such effect of food plant could be found for T. leucopterus, suggesting the existence of alternative defences in this species. 3. The number of attacks was lower when host plant-fed larvae of both species were presented in groups. 4. The discussion concerns how major components of an aposematic syndrome, such as host plant chemistry, insect colouration, and aggregation, are integrated with other life-history traits to form alternative lifestyles in L. equestris and T. leucopterus. Key words. Aggregation, Asclepiadaceae, defence, host plant, life history, Lygaeinae, Lygaeus equestris, palatability, Tropidothorax leucopterus. Introduction There is, however, considerable variation in the degree to which milkweed bugs utilise cardenolide-containing plants and Many species of milkweed bugs (Heteroptera: Lygaeidae: some species tend to be polyphagous, feeding also on plants Lygaeinae) are aposematically coloured and feed on various lacking these and other poisonous substances.

    Chapter 1 Introduction to True Bugs (Heteroptera) of the Neotropics Antônio R. Panizzi and Jocêlia Grazia Abstract True bugs (Heteroptera) are a diverse and complex group of insects, particularly in the neotropics. The fauna ofthese bugs has been investigated through time, but our knowledge of the species living in the Neotropical Region is lirnited. ln this introductory chapter, we give a general view on true bugs c1assification and biogeography, with concise comments on their general characteristics and bioecology of each major taxon that comprise each of the seven infraorders of Heteroptera. 1.1 Introduction The true bugs (Heteroptera) constitute a very interesting widely distributed group of insects, which is greatly diversified in tropical zones. Considered the largest group of insects with incomplete metamorphosis, heteropterans have been studied on both basic and applied aspects worldwide. Along the years, several books have been published on Heteroptera, the majority on specific aspects, such as certain groups (taxa) of particular areas, and others on more general comprehensive issues. Of more broad interest, two books about the latter were published relatively recently. The first was dedicated to the c1assification and natural history of true bugs in particular, with insights on the history of the study of Heteroptera, how to collect and preserve true bugs, historical biogeogra- A.R.

BARANOWSKI1 AND HARRY BRAILOVSKY2 1University of Florida, Institute of Food and Agricultural Sciences Tropical Research and Education Center, Homestead, Fl 33031 USA 2Instituto de Biología, Universidad Nacional Autónoma de México Departamento de Zoología, Apdo. Postal 70153, México 04510 D.F. ABSTRACT A new species of Hadrosomus A. Slater from Dominican Republic is described; a key to the known species is included and the dorsal view and parameres are illus- trated. Key Words: West Indies, Heteroptera, Lygaeinae, Hadrosomus, new species RESUMEN Se decribe una nueva especie del género Hadrosomus A. Slater, recolectada en Re- pública Dominicana y se incluye una clave para separar las especies conocidas; los pa- rámeros y el ejemplar en vista dorsal son ilustrados. In a revision of the Western Hemisphere Lygaeinae A. Slater (1992) recognized 22 genera, 7 subgenera, and 198 species. Each genus and subgenus is described or re- described and a key to genera, subgenera and species is included. Line drawings of head, metapleuron, spermatheca, ovipositor, parameres, and aedeagus are provided, as well as a cladistic analysis of the genera. One of the new taxa proposed by A. Slater was Hadrosomus, with three species: H. confraternus (Uhler) distributed from South-central México to southern Brasil, including the Dominican Republic and Trinidad, H. teapensis (Distant), the type species,

Altogether, 1,564 species taxa (identifi ed at least to the genus level) from 25 orders of Hexapoda have been recorded from the Socotra Archipelago to date. In addition, members of Diplura and Ephemeroptera are known from the archipelago as well, but they have not been identifi ed so far. The most speciose order in Socotra are beetles (Coleoptera) with 540 species. The total number of endemic taxa described from the archipelago is 662 species, which represents 42% of all known species. The vast majority of species is known from the main Socotra Island (1,520 species, 635 endemic taxa). The diversity of insects in Socotra is briefl y commented on and compared with the nearest archipelago – the Seychelles. Key words. Hexapoda, biodiversity, endemism, insect survey, Socotra, Yemen Introduction An extensive research of invertebrate diversity of the Socotra Archipelago in the last 20 years resulted in numerous publications containing descriptions of new taxa as well as new faunistic records from Socotra.
