Neotropical Biology and Conservation 15(3): 359–366. https://doi.org/10.3897/neotropical.15.e55148 Abstract The Plant Vigour Hypothesis states that herbivores preferentially feed on the most vigorous plants within a plant population and/or the most vigorous modules within a plant. The goal of this study was to evaluate how shoot size (as an indication of module vigour) affects leaf herbivory in the host plant Calotropis procera, an exotic xerophyte perennial milkweed shrub. We predicted that the proportion of leaf area removed by insect herbivores would be positively related to shoot size. Eight patches were selected containing a varied number of C. -

RESEARCH ARTICLE Data-driven identification of potential Zika virus vectors Michelle V Evans1,2*, Tad A Dallas1,3, Barbara A Han4, Courtney C Murdock1,2,5,6,7,8, John M Drake1,2,8 1Odum School of Ecology, University of Georgia, Athens, United States; 2Center for the Ecology of Infectious Diseases, University of Georgia, Athens, United States; 3Department of Environmental Science and Policy, University of California-Davis, Davis, United States; 4Cary Institute of Ecosystem Studies, Millbrook, United States; 5Department of Infectious Disease, University of Georgia, Athens, United States; 6Center for Tropical Emerging Global Diseases, University of Georgia, Athens, United States; 7Center for Vaccines and Immunology, University of Georgia, Athens, United States; 8River Basin Center, University of Georgia, Athens, United States Abstract Zika is an emerging virus whose rapid spread is of great public health concern. Knowledge about transmission remains incomplete, especially concerning potential transmission in geographic areas in which it has not yet been introduced. To identify unknown vectors of Zika, we developed a data-driven model linking vector species and the Zika virus via vector-virus trait combinations that confer a propensity toward associations in an ecological network connecting flaviviruses and their mosquito vectors. Our model predicts that thirty-five species may be able to transmit the virus, seven of which are found in the continental United States, including Culex quinquefasciatus and Cx. pipiens. We suggest that empirical studies prioritize these species to confirm predictions of vector competence, enabling the correct identification of populations at risk for transmission within the United States. *For correspondence: mvevans@ DOI: 10.7554/eLife.22053.001 uga.edu Competing interests: The authors declare that no competing interests exist. -

A significantly higher proportion of the vector species that were initially attracted to a cow fed when released into a net with a cow than when released into a net containing a pig. However, Culex vishnui individuals that had been attracted to a pig had a higher feeding rate in a net containing a pig rather than a cow. When mosquitoes were given a choice by being released into a net containing both animals, they exhibited a tendency to feed on the host to which they had originally been attracted. -

The plant is poisonous can lead to blindness if its juice is put in to the eyes. The silky hairs are using to stuff pillows. The wood is used in impoverished desert areas for a cooking fuel. The stem is useful for making ropes, carpets, fishing nets and sewing thread. The wood is used in making charcoal. C. procera is an ideal plant for monitoring sulphur dioxide emissions in the air. C. procera is a potential plant for bioenergy and biofuel production in semi arid regions of the country. -
A Review of the Mosquito Species (Diptera: Culicidae) of Bangladesh Seth R
Irish et al. Parasites & Vectors (2016) 9:559 DOI 10.1186/s13071-016-1848-z RESEARCH Open Access A review of the mosquito species (Diptera: Culicidae) of Bangladesh Seth R. Irish1*, Hasan Mohammad Al-Amin2, Mohammad Shafiul Alam2 and Ralph E. Harbach3 Abstract Background: Diseases caused by mosquito-borne pathogens remain an important source of morbidity and mortality in Bangladesh. To better control the vectors that transmit the agents of disease, and hence the diseases they cause, and to appreciate the diversity of the family Culicidae, it is important to have an up-to-date list of the species present in the country. Original records were collected from a literature review to compile a list of the species recorded in Bangladesh. Results: Records for 123 species were collected, although some species had only a single record. This is an increase of ten species over the most recent complete list, compiled nearly 30 years ago. Collection records of three additional species are included here: Anopheles pseudowillmori, Armigeres malayi and Mimomyia luzonensis. Conclusions: While this work constitutes the most complete list of mosquito species collected in Bangladesh, further work is needed to refine this list and understand the distributions of those species within the country. Improved morphological and molecular methods of identification will allow the refinement of this list in years to come.

The study was focused for documentation of traditional knowledge of local people about use of native medicinal plants as ethnomedicines. The method followed for documentation of indigenous knowledge was based on questionnaire. The interviews were held in local community, to investigate local people and knowledgeable persons, who are the main user of medicinal plants. The ethnomedicinal data on 55 plant species belonging to 52 genera of 30 families were recorded during field trips from six remote villages of the area. The check list and ethnomedicinal inventory was developed alphabetically by botanical name, followed by local name, family, part used and ethnomedicinal uses. Plant specimens were collected, identified, preserved, mounted and voucher was deposited in the Department of Botany, University of Arid Agriculture Rawalpindi, for future references. Key words: Checklist, medicinal flora and Mianwali-Pakistan. INTRODUCTION District Mianwali derives its name from a local Saint, Mian Ali who had a small hamlet in the 16th century which came to be called Mianwali after his name (on the eastern bank of Indus). The area was a part of Bannu district. The district lies between the 32-10º to 33-15º, north latitudes and 71-08º to 71-57º east longitudes. The district is bounded on the north by district of NWFP and Attock district of Punjab, on the east by Kohat districts, on the south by Bhakkar district of Punjab and on the west by Lakki, Karak and Dera Ismail Khan District of NWFP again. -

International Letters of Chemistry, Physics and Astronomy Online: 2013-10-16 ISSN: 2299-3843, Vol. 20, pp 74-90 doi:10.18052/www.scipress.com/ILCPA.20.74 CC BY 4.0. Published by SciPress Ltd, Switzerland, 2014 The Chemical Study of Calotropis Vishwa Nath Verma Department of Chemistry, Faculty of Natural Sciences, University of Guyana, Turkeyen Campus, Georgetown, Guyana, South America Email address: [email protected] ABSTRACT Calotropis (Asclepiadaceae) commonly known as “madar” is a useful medicinal plant. The two species i.e. Calotropis gigantea and Calotropis procera are to a great extent having a very similar chemical properties, but the colours of their flowers are different. The pH of latex of these two species has been found different in the present study. The temperature effects have been noticed on their pH values which is varying from 7.2 to 8.1 between the temperatures 25 °C to 45 °C and then remains constant for Calotropis gigantia. The milky latex contains hydrocarbons, fatty acids, sterols and terpenels. Seven spots have been observed on the TLC plates; out of which 3 were identified as calotoxin, uscharin and calactin. Aluminum, calcium, cadmiun, cobalt, chromium, copper, iron, magnese, magnesium, nickel, lead, and zinc metal elements were investigated in the latex and similarly in the leaves and bark from the AA spectra. The amount of magnese was found the highest in the latex of both species but calcium was found highest in leaves and bark of both species. Copper, chromium and lead were not found at all in latex but a very little amount of copper and lead were found in leaves and bark. -

Meta-Analyses of the Proportion of Japanese Encephalitis Virus Infection in Vectors and Vertebrate Hosts Ana R.S
Oliveira et al. Parasites & Vectors (2017) 10:418 DOI 10.1186/s13071-017-2354-7 RESEARCH Open Access Meta-analyses of the proportion of Japanese encephalitis virus infection in vectors and vertebrate hosts Ana R.S. Oliveira1, Lee W. Cohnstaedt2, Erin Strathe3, Luciana Etcheverry Hernández1, D. Scott McVey2, José Piaggio4 and Natalia Cernicchiaro1* Abstract Background: Japanese encephalitis (JE) is a zoonosis in Southeast Asia vectored by mosquitoes infected with the Japanese encephalitis virus (JEV). Japanese encephalitis is considered an emerging exotic infectious disease with potential for introduction in currently JEV-free countries. Pigs and ardeid birds are reservoir hosts and play a major role on the transmission dynamics of the disease. The objective of the study was to quantitatively summarize the proportion of JEV infection in vectors and vertebrate hosts from data pertaining to observational studies obtained in a systematic review of the literature on vector and host competence for JEV, using meta-analyses. Methods: Data gathered in this study pertained to three outcomes: proportion of JEV infection in vectors, proportion of JEV infection in vertebrate hosts, and minimum infection rate (MIR) in vectors. Random-effects subgroup meta-analysis models were fitted by species (mosquito or vertebrate host species) to estimate pooled summary measures, as well as to compute the variance between studies. Meta-regression models were fitted to assess the association between different predictors and the outcomes of interest and to identify sources of heterogeneity among studies. Predictors included in all models were mosquito/vertebrate host species, diagnostic methods, mosquito capture methods, season, country/region, age category, and number of mosquitos per pool. -

College University, Faisalabad, Pakistan *Corresponding author E-mail: [email protected]; 00 92 0321-5167726 Abstract A survey of motorway (M-2) roadside vegetation and soils was undertaken. In this study, phytosociological survey using Braun-Blanquet’s approach was undertaken. The floristic data were analyzed by the TWINSPAN and DECORANA, computer programs in order to classify and provide baseline information about the study area. Two major and 16 sub-communities were recognized along 358 km long motorway. Floristic data was collected from 397 quadrats and 227 vascular plants species belonging to 75 families were recorded. TWINSPAN divided the vegetation of whole study area into 2 major communities, which are further divided into 16 sub-communities. The study also provides basic information for the implementation of conservation oriented planning and management to preserve and improve the road verges of M-2. Introduction The human impact has always been a dominant factor in affecting different aspects of earth environment. Among the various means of transportation, roads enjoy a prime position because these constitute the largest and most extensive functioning system of transport on the earth (Bayliss & Owens, 1990). In Pakistan presently about 80% of the goods and passenger traffic is on the roads and remaining 20% is carried by other modes, namely, railways and airways. -
