Biosystems Diversity, 26(4), 263–268. doi:10.15421/011840 Received in revised form 07.11.2018 A total of 63 species of true bugs in 53 genera and 11 families of the infraorder Pentatomomorpha was recorded from the city of Accepted 17.11.2018 Kharkiv. For one species, Carpocoris purpureipennis (Pentatomidae), we obtained the first record from Left-Bank Ukraine. Formerly, this species was known from Western and Central Ukraine only. Four species of the family Lygaeidae (Nysius ericae, Perithrechus H. S. Skovoroda Kharkiv geniculatus, P. gracilicornis, Taphropeltus contractus) are new to Kharkiv Region. The families Lygaeidae (23 species of 19 genera, National Pedagogical 38.3% of the total collected bugs), Pentatomidae (16 species of 14 genera, 26.7%), Rhopalidae (7 species of 5 genera, 11.7%), and University, Valentynivska st., 2, Coreidae (6 species of 6 genera, about 3%) were the most rich in species and individual numbers. The families of Berytidae, Cydnidae Kharkiv, 61000, Ukraine. Tel.: +38-096-708-84-73, and Scutelleridae were represented by two species each (3.3% out of the total collected bugs). Six species (Myrmus miriformis, Lygaeus E-mail: equestris, Scolopostethus pictus, Aelia acuminata, Graphosoma lineatum, and Pyrrhocoris apterus) were abundant, eight species [email protected], common, 14 species rare, and 32 species belonged to occasional elements of the urban cenoses. The true bug species composition and [email protected] individual abundance were the highest in the suburban meadows and large city parks (44 and 27 species, respectively). By contrast, only Schmalhausen seven species were registered in the green areas of the city centre (lawns, public gardens). Faunal similarity (Jaccard / Chekanovsky- Institute of Zoology Sørensen indices) of the true bug assemblages was the lowest when comparing public gardens of the city centre with the habitats of the of the NAS of Ukraine, suburbs and city parks (0.04–0.06 / 0.07–0.12), and the highest between the meadows and urban parks with glades and grassy vegetation B.

Tel.: +38-095-462-62-23. (0.1‒0.42). The average Pentatomomorpha similarity in different urban cenoses was also low (Jaccard index 0.27, Chekanovsky- E-mail: Sørensen index 0.39). The essential faunal differences can be explained by both the low number of most Pentatomomorpha species and [email protected] their ecological peculiarities. The proportions of various ecological groups of bugs in different urban cenoses were analyzed and discussed. Major differences were observed in the species habitat distributions while the lesser differences concerned trophic groups and hygropreferences of most species.

(Hemiptera: Alydidae) Using White MuscardineFungus Beauveriabassiana (Bals.) Vuill.In Upland Rice Pio P. Tuan, PhD* Department of Agricultural Sciences, College of Agriculture, Fisheries, and Natural Resources University of Eastern Philippines, University Town, Catarman, Northern Samar, Philippines Abstract A field experiment was conducted to evaluate the incidence of Rice bug, Leptocorisaoratorius(F.) using B. bassiana as mycoinsectice under upland conditions. Field population of L. oratorius was not significantly affected by B. bassiana7 DAS, but significant at 15 DAS. The application of B. bassiana did not significantly affect the damage caused by L. oratoriuson rice grains.The results suggest that B. bassiana cannot be used as a sole mortality factor in the management of rice bug under upland conditions. More field experimentations are necessary taking into consideration the influence of environmental factors and how these can be manipulated in favor of the fungal insecticide. Key Words: Conidia, substrate, microbial insecticide, upand rice, abiotic environmental factors INTRODUCTION Rice bug, Leptrocorisaoratorius (F.) is one of the major insect pests infesting rice in upland areas. Several species of rice bugs occur in the Philippines, but L. oratorius is the most prevalent (Reissig et al., 1986; Litsinger et al., 1987). Upland rice is usually cultivated for organic rice or with less application of fertilizer and pesticides. The increasing demand for organically produced foods including rice, has contributed to the adoption of ecologically oriented pest control methods. Consequently, reduced pesticide use has become a strong option to protect the environment and human health.

  • Broad-Headed Bugs (Alydidae)
    Chapter 18 Broad-Headed Bugs (Alydidae) Antônio R. Panizzi and Carl w. Schaefer Abstract The broad-headed bugs (Alydidae) are divided into two subfamilies, Alydinaeand Micrelytrinae, each divided into two tribes, Daclerini and Alydini, and Micrelytriniand Leptocorisini, respectively, The farnily has 53 genera and about 250 specieins; the Neotropics, there are 21 genera. Alydids are small (8-20 mm), slen- Itr,with a triangular head; nymphs of alydines mimic ants, the adults of some Micrelytrinialso rnirnic ants. The most studied species in the Neotropics is the aly- dineNeomegalotomus parvus (Westwood), usually associated with legumes, and maybe a pest on soybean. Other common genera include Hyalymenus Amyot & Serville,Stenocoris Burmeister, Cydamus Stâl, and Trachelium Herrich-Schâffer. Studieson taxonomy and bioecology on alydids of the Neotropics are needed. 18.1 Introduction AlydidaeAmyot and Serville, 1843, were treated as a subfarnily of the farnily Coreidaeand even as a tribe (Schaffner 1964); now it has been treated as a farnily, ~ether with Coreidae, Rhopalidae, Hyocephalidae, and Stenocephalidae, in the !UperfarniCoreoidealy (Schaefer 1964). Thisfarnily contains 53 genera and approximately 250 species, mostly tropical Irsubtropical,in all regions of the world. There are only two genera that span both dleOldand the New World, Alydus and Megalotomus. These genera are Holarctic, IInAlydus extends from Alaska through Canada into Mexico (Brailovsky and Flores 1979;Froeschner 1988; Maw et al. 2000). The genera of Alydinae have been revised by Schaffner (1964; 22 species worldwide);the world genera of the subfamily Micrelytrinae, tribe Leptocorisini, were CarlW.Schaefer: Author deceased at the time of publication A.RP.anizzi ([gJ) Laboratóriode Entomologia, Embrapa Trigo, Caixa Postal 3081, Passo Fundo, RS9900l-970,Brazil e-mail:[email protected] eSpringerScience-Business Media Dordrecht 2015 537 :I.R.Panizzi,J.

  • The Stilt Bugs (Heteroptera, Berytidae) of Norway
    © Norwegian Journal of Entomology. 21 June 2011 The stilt bugs (Heteroptera, Berytidae) of Norway FRODE ØDEGAARD & ARNSTEIN STAVERLØKK Ødegaard, F. & Staverløkk, A. 2011. The stilt bugs (Heteroptera, Berytidae) of Norway. Norwegian Journal of Entomology 58, 27–32. We here present confirmed records of the six species of stilt bugs (Berytidae) occurring in Norway. Berytinus clavipes (Fabricius, 1775) is reported for the first time from Norway. Several new county records for the other species of Berytidae are also presented. All species are illustrated with pictures of specimens from Norway. The reported records of Berytinus affinis in Warloe (1925) have for a long time led to confusion about which species of Berytinus Kirkaldy, 1900 being present in Norway. Here, we show that these specimens actually belong to the common B. minor (Herrich-Schaeffer, 1835). We conclude that it is not likely that more than these six species of Berytidae are to be found in Norway in the future. Key words: Hemiptera, Heteroptera, Berytidae, Norway.

The stilt bugs (Berytidae) represent a small family While Metatropis rufescens is found in broad leaved of true bugs with 155 species and 45 genera in the forests, all the other species seem to be restricted Palearctic region (Aukema & Rieger 2001) Only to xerophilic dry meadows. The Berytinus species eight of these species are present in Scandinavia are normally associated with Fabaceae.

Specifically, this area is composed of various habitats, including forests, open soils, ruderal habitats and a sewage water body. Based on our findings, we suggest appropriate interventions or changes in management to support and enhance local biodiversity. Our results showed that species composition of plants and animals in the quarry premises is characterized mostly by common species (with only few plant taxa exception) without any specific habitat requirements. We found that the most botanically valuable habitats in Bobroviště are the forest fragment and the spring with its immediate vicinity. Since wetland habitats became valuable in the respect of climate changes in the last few years, we suggest creating new ponds and a littoral zone in the sewage water body to enhance biodiversity of this area and consequently increase water retention in the landscape. Introduction Mining areas are often perceived by the public as a scar on the landscape.
