Although these medically important Rickettsia are often transmitted via haematophagous arthropods, other Rickettsia, such as those in the Torix group, appear to reside exclusively in invertebrates and protists with no secondary vertebrate host. Importantly, little is known about the diversity or host range of Torix group Rickettsia. -
Deraeocoris Schach, a New Predator of Euphydryas Aurinia and Other Heteropteran Feeding Habits on Caterpillar Web (Heteroptera: Miridae; Lepidoptera: Nymphalidae)

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. -

Discrimination Between Eggs from Stink Bugs Species in Europe Using MALDI-TOF MS
insects Article Discrimination between Eggs from Stink Bugs Species in Europe Using MALDI-TOF MS Michael A. Reeve 1,* and Tim Haye 2 1 CABI, Bakeham Lane, Egham, Surrey TW20 9TY, UK 2 CABI, Rue des Grillons 1, CH-2800 Delémont, Switzerland; [email protected] * Correspondence: [email protected] Simple Summary: Recent globalization of trade and travel has led to the introduction of exotic insects into Europe, including the brown marmorated stink bug (Halyomorpha halys)—a highly polyphagous pest with more than 200 host plants, including many agricultural crops. Unfortunately, farmers and crop-protection advisers finding egg masses of stink bugs during crop scouting frequently struggle to identify correctly the species based on their egg masses, and easily confuse eggs of the invasive H. halys with those of other (native) species. To this end, we have investigated using matrix-assisted laser desorption and ionization time-of-flight mass spectrometry (MALDI-TOF MS) for rapid, fieldwork-compatible, and low-reagent-cost discrimination between the eggs of native and exotic stink bugs. Abstract: In the current paper, we used a method based on stink bug egg-protein immobilization on filter paper by drying, followed by post-(storage and shipping) extraction in acidified acetonitrile containing matrix, to discriminate between nine different species using MALDI-TOF MS. We obtained 87 correct species-identifications in 87 blind tests using this method. With further processing of the unblinded data, the highest average Bruker score for each tested species was that of the cognate Citation: Reeve, M.A.; Haye, T. reference species, and the observed differences in average Bruker scores were generally large and the Discrimination between Eggs from errors small except for Capocoris fuscispinus, Dolycoris baccarum, and Graphosoma italicum, where the Stink Bugs Species in Europe Using average scores were lower and the errors higher relative to the remaining comparisons. -
Chemical Analysis of the Metathoracic Scent Gland of Eurygaster Maura (L.) (Heteroptera: Scutelleridae)
J. Agr. Sci. Tech. (2019) Vol. 21(6): 1473-1484 Chemical Analysis of the Metathoracic Scent Gland of Eurygaster maura (L.) (Heteroptera: Scutelleridae) E. Ogur1, and C. Tuncer2 ABSTRACT Eurygaster maura (L.) (Heteroptera: Scutelleridae) is one of the most devastating pests of wheat in Turkey. The metathoracic scent gland secretions of male and female E. maura were analyzed separately by gas chromatography-mass spectrometry. Twelve chemical compounds, namely, Octane, n-Undecane, n-Dodecane, n-Tridecane, (E)-2-Hexenal , (E)- 2-Hexen-1-ol, acetate, Cyclopropane, 1-ethyl-2-heptyl, Hexadecane, (E)-3-Octen-1-ol, acetate, (E)-5-Decen-1-ol, acetate, 2-Hexenoic acid, Butyric acid, and Tridecyl ester were detected in both males and females. These compounds, however, differed quantitatively between the sexes. In both females and males, n-Tridecane and (E)-2-Hexanal were the most abundant compounds and constituted approximately 90% of the total content. Minimal amounts of Octane were detected in males and Hexadecane in females. Keywords: (E)-2-Hexenal, GC-MS, Metathoracic scent gland, n-Tridecane, Wheat.

In the case of insects, most published DNA barcoding studies focus on species of the Ephemeroptera, Trichoptera, Hymenoptera and especially Lepidoptera. In this study we test the efficiency of DNA barcoding for true bugs (Hemiptera: Heteroptera), an ecological and economical highly important as well as morphologically diverse insect taxon. As part of our study we analyzed DNA barcodes for 1742 specimens of 457 species, comprising 39 families of the Heteroptera. We found low nucleotide distances with a minimum pairwise K2P distance ,2.2% within 21 species pairs (39 species). For ten of these species pairs (18 species), minimum pairwise distances were zero. In contrast to this, deep intraspecific sequence divergences with maximum pairwise distances .2.2% were detected for 16 traditionally recognized and valid species. With a successful identification rate of 91.5% (418 species) our study emphasizes the use of DNA barcodes for the identification of true bugs and represents an important step in building-up a comprehensive barcode library for true bugs in Germany and Central Europe as well. -
Are Gregarious Red-Black Shieldbugs, Graphosoma Lineatum (Hemiptera: Pentatomidae), Really Aposematic? an Experimental Approach
Evolutionary Ecology Research, 2006, 8: 881–890 Are gregarious red-black shieldbugs, Graphosoma lineatum (Hemiptera: Pentatomidae), really aposematic? An experimental approach Petr Veselý,* Silvie Veselá, Roman Fuchs and Jan Zrzavý Department of Zoology, Faculty of Biological Sciences, University of South Bohemia, Branisˇovská 31, 370 05 Cˇ eské Budeˇjovice, Czech Republic ABSTRACT Hypothesis: The coloration of the red-black shieldbug has a warning function. This quality can be lowered when the shieldbug is presented on a fragmented background. Organism: We offered wild-coloured and artificially deaposematized (painted brown) red-black shieldbugs (Graphosoma lineatum) to avian predators (Parus major, Parus caeruleus). Site of experiments: The experiments were conducted in a cage (0.7 m × 0.7 m × 0.7 m) fitted with a one-way mirror. Methods: In succession, we offered five shieldbugs to each bird. We presented the shieldbugs on contrasting (white) and matching (imitating the shieldbug’s habitat and imitating the striated shieldbug pattern) backgrounds. Results: The blue tits avoided all shieldbugs offered to them regardless of their coloration. The great tits attacked both colour forms, but the brown one more frequently. The wild-coloured shieldbugs were significantly better protected against repeated attacks. Shieldbugs presented on any of the matching backgrounds were attacked less frequently than when presented on the white background. Keywords: disruptive coloration, Parus caeruleus, Parus major, warning coloration. INTRODUCTION Warning (aposematic) colouration, which provides protection to a defended species against visually oriented predators (usually birds), is a controversial topic in evolutionary ecology. The initial evolution of aposematic anti-predator signalling is expected to increase predation risk before reaching a stage when local predators are able to learn to avoid the unpalatable prey (see Lindström et al., 2001; Marples et al., 2005). -
Effect of Photoperiod on Flight Activity in Graphosoma Lineatum
NOTE Eur. J. Entomol. 95: 297-300, 1998 ISSN 1210-5759 Effect of photoperiod on flight activityGraphosoma in lineatum (Heteroptera: Pentatomidae) K eui NAKAMURA1, M agdalena HODKOVÁ2 and Ivo HODEK2 'Department of Biology, Faculty of Science, Osaka City University, Sumiyoshi, Osaka 558, Japan; e-mail: [email protected] institute of Entomology, Czech Academy of Sciences, Branišovská 31,370 05 České Budějovice, Czech Republic; e-mail: [email protected] Graphosoma lineatum, Pentatomidae, adult diapause, hibernation, photoperiod, flight activity, host plant, breeding site, foraging Abstract. Flight activity in a pentatomid bug, Graphosoma lineatum, was measured under different pho- toperiodic conditions. Insects started flying 3 days after adult ecdysis and the percentage of flying adults became highest about 1 week after the ecdysis, regardless of the photoperiod. Under long day (18L : 6D), high flight activity was continued, whereas under short day (12L : 12D), most adults stopped flying when diapause was induced. In both photoperiods, a small number of adults showed flight of a long duration, longer than 30 minutes. Thus, no evidence was found relating the long flight to diapause. It is suggested that diapause adults of G. lineatum do not overwinter far from their breeding sites and thus there is no mi gration to hibernation sites. Also, the long flight is probably only a foraging flight, enabling the bugs to find their dispersed host plants. Introduction In insects hibernating or estivating far from their breeding sites, the early period of diapause (or predia pause) is characterised by migration (Johnson, 1969). Experimental analysis often reveals that a diapause- promoting photoperiod induces not only diapause but also long-distance flight that is linked to the dia pause syndrome.
