  • Elytra Reduction May Affect the Evolution of Beetle Hind Wings
    Zoomorphology https://doi.org/10.1007/s00435-017-0388-1 ORIGINAL PAPER Elytra reduction may affect the evolution of beetle hind wings Jakub Goczał1 · Robert Rossa1 · Adam Tofilski2 Received: 21 July 2017 / Revised: 31 October 2017 / Accepted: 14 November 2017 © The Author(s) 2017. This article is an open access publication Abstract Beetles are one of the largest and most diverse groups of animals in the world. Conversion of forewings into hardened shields is perceived as a key adaptation that has greatly supported the evolutionary success of this taxa. Beetle elytra play an essential role: they minimize the influence of unfavorable external factors and protect insects against predators. Therefore, it is particularly interesting why some beetles have reduced their shields. This rare phenomenon is called brachelytry and its evolution and implications remain largely unexplored. In this paper, we focused on rare group of brachelytrous beetles with exposed hind wings. We have investigated whether the elytra loss in different beetle taxa is accompanied with the hind wing shape modification, and whether these changes are similar among unrelated beetle taxa. We found that hind wings shape differ markedly between related brachelytrous and macroelytrous beetles. Moreover, we revealed that modifications of hind wings have followed similar patterns and resulted in homoplasy in this trait among some unrelated groups of wing-exposed brachelytrous beetles. Our results suggest that elytra reduction may affect the evolution of beetle hind wings.

However, recent studies have The Coleoptera order encompasses almost the quarter of all provided evidence that formation of elytra in beetles is less currently known animal species (Grimaldi and Engel 2005; affected by Hox gene than previously expected (Tomoyasu Hunt et al.

Fomina The purpose. To carry out probes on revealing and specification of species composition of checkered moths (Lepidoptera: Gracillariidae) in conditions of botanical gardens and plantings of Kiev. Methods. Standard methods of faunistic research in entomology, population ecology, and protection of plants. Results. It is determined that 24 kinds of checkered moths are eating 54 kinds of plants which are widely used for gardening in Kiev. For the first time the following kinds are revealed: Phyllonorycter issikii, Phyllonorycter platani, and Phyllonorycter emberizaepennella. At calculation of Palii-Kovnatski indexes they specified that in city plantings the dominant phytophags are Cameraria ohridella (94,11%), Phyllonorycter populifoliella (86,37%) and Gracillaria syringella (59,14%). They consider that in formation of the secondary areal of invasion kinds of checkered moths the great value has an areal of spread of the host-plant. Environmental analysis is carried out of checkered moths of family Gracillariidae which is spread in cities of the Europe and which are absent in fauna of cities of Ukraine. That has important theoretical and practical value for ecology, entomology and protection of plants against hazardous checkered moths. Conclusions. All the probed kinds of checkered moths by their trophic specialization may be distributed into polyphages (6 kinds), oligophages (14 kinds) and monophages (3 kinds).

In this work, we combined the artificial fish swarm and improved particle swarm optimization (AFSA-PSO) algorithms. Taking the Window of the World station of the Shenzhen Metro Line 1 as an example, subway passenger flow prediction research was carried out. The AFSA-PSO algorithm successfully preserved the fast convergence and strong traceability of the original algorithm through particle self-adjustment and dynamic weights, and it effectively overcame its shortcomings, such as the tendency to fall into local optimum and lower convergence speed.

About “Creative Village” Tengchong, southwest of Yunnan Province, is well known in domestic and abroad for its rich natural resources like volcanic, Atami and Heshun town. The historical and cultural city on the Silk Road is an important gateway for China to South Asia and Southeast Asia, which is also the most popular tourist destination for visitors. Relying on the innate good natural environment, abundant tourism resources, profound cultural historical heritage, the current 2016 Tengchong-L&A Design Star "Creative Village" international competition use Hehua Dai and Wa Ethnic Township, southwest of Tengchong city, as the design field. In this way, we want to explore a consolidation pattern of cultural and creative tourism, rural construction and industrial heritage in the new era. We hope to increase added value in tourism product by promote the popularity of the town, and change the traditional development mode through reasonable scenic area planning and design. In addition to the magnificent ground water and underground river resources, constant perennial water with low temperature "Bapai Giant Hot Springs ", Hehua town also has Hehua Sugar Factory as industrial heritage constructed in 1983 and a rural settlement called Ba Pai village with rich humanistic resources. Students all over the world will work together to integrate and promote the high quality resources of field in three months. And finally make the scheme a new type of tourism destination solution based on southwest and facing the world. This international design competition is open to all university students both domestic and abroad, aiming to formulate creative strategies from a global perspective for the transformation of beautiful Chinese villages.

No tactic is able to protect plants completely against virus infections when used alone, except for certain fleeces. Multiple tactics must be used to build integrated pest management programs (IPM).
