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. -
Removal of Gut Symbiotic Bacteria Negatively Affects Life History Traits of the Shield Bug, Graphosoma Lineatum

Considering vertical transmission of the bacterial symbiont through the Email: [email protected] egg surface contamination, we used surface sterilization of the eggs to remove the symbiont. The symbiont population was decreased in the newborn nymphs hatched from the surface- sterilized eggs (the aposymbiotic insects), and this reduction im- posed strongly negative effects on the insect host. We found significant differences in most life table parameters between the symbiotic insects and the aposymbiot- −1 ics. The intrinsic rate of increase in the control insects (0.080 ± 0.003 day ) was −1 higher than the aposymbiotic insects (0.045 ± 0.007 day ). Also, the net reproduc- tive and gross reproductive rates were decreased in the aposymbiotic insects (i.e., 20.770 ± 8.992 and 65.649 ± 27.654 offspring/individual, respectively), compared with the symbiotic insects (i.e., 115.878 ± 21.624 and 165.692 ± 29.058 offspring/ individual, respectively). -

Predator Dependent Mimetic Complexes: Do Passerine Birds Avoid Central European Red-And-Black Heteroptera?

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. -

The range of habitats and host plants used by this species is wider than commonly believed. While many populations are found in seasonal or permanent wetlands, others are located in dry, old fields or woodland areas. The host plants used vary with habitat, but they include all major primary hosts and many second ary hosts previously reported plus several new records. -

It is considered as one of the largest family within suborder Heteroptera. In the present study, partial mitochondrial COI gene fragment of approximately 600bp from seven species of family Pentatomidae collected from different localities of Northern India has been analysed. The data divulged an A+T content of 65.8% and an R value of 1.39. The COI sequences were added directly to Genbank NCBI. The database analysis shows mean K2P divergence of 0.7% at intraspecific level and 13.5% at interspecific level, indicating a hierarchal increase in K2P mean divergence across different taxonomic levels. Keywords: pentatomidae, mitochondrial gene, COI Introduction Punjabi University, Patiala.

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.
