Two novel flight-interception trap designs for low-cost forest insect surveys

This paper introduces two passive trap designs for the survey of flying Coleoptera and other insects which can be constructed on very low budgets at < £1 per trap. A trunk window trap and an aerial flight-interception trap are presented, based on commonly used designs, but using much cheaper materials than standard. Construction diagrams are given, along with a description of trap installation, operation and beetle species found using these methods during a survey of Ayr Gorge Woodland, South-West Scotland. The traps were found to be robust and easy to operate. It is hoped that these trap designs will be of use to charitable organisations, students and amateurs who may previously have been unable to consider monitoring flying insects at large scales due to the prohibitive cost of equipment

A specimen of Tirumala hamata hamata (Macleay, 1826) (Lepidoptera: Danainae) from Captain Cook’s first voyage

On 29 May 1770 Joseph Banks described a spectacular swarming of ‘milions’ [sic] ‘of one sort’ of butterfly at Thirsty Sound, near what is now Rockhampton, Queensland, comparing it to a species from China that had been named by Linnaeus. Discovery of what appears to be an Endeavour voyage specimen of this Australian butterfly in the Hunterian Zoology Museum, Glasgow, allows us to confirm its long-suspected identity as Tirumala hamata hamata (Macleay) – a species unnamed and unknown at the time of Cook’s first voyage. Investigations into several collections that include eighteenth-century Australian Lepidoptera and associated literature have not positively identified any further specimens taken from the swarm, although a pair in the Oxford University Museum of Natural History could be from the same source. Taxonomic confusion due to mimicry, convergence and/or non-divergence affecting blue tiger patterned butterflies is most likely the principal reason such a specimen has previously gone undetected

A non-destructive virtual dissection by micro-CT reveals diagnostic characters in the type specimen of Caloptilia stigmatella (Lepidoptera: Gracillariidae)

Nearly a century ago, wing venation pattern was introduced in the gracillariid taxonomy to diagnose the closely related genera and species groups. Recent advances in non-destructive virtual micro-dissections suggest a promising approach in revisiting the relevance of wing venation characters and application of this method to historic primary type specimens. Many unique type specimens in Gracillariidae and other microlepidoptera groups are preserved in the museum collections in poor condition and in the course of history suffered loss or damage to their abdomens, so internal genitalia structural morphology is not available for diagnosis and comparisons. The interpretation of wing venation characters became a significant element in Gracillariidae taxonomy dealing with species complexes and defining the boundaries of genera. In this paper we emphasize the need to include the type species and type specimens into the broader context of taxonomic studies on micro moths in general and the family Gracillariidae in particular. For the first time we introduce the method of virtual descaling of the wings in micro moths. The genus Caloptilia with a world-wide distribution has more than 200 years history of research, but the generic boundaries and groupings within the genus are not resolved yet due to the lack of a reliable set of taxonomic characters obtained from the primary types. We describe a method of virtual descaling of the fore and hindwings of an unset micro-moth type specimen Caloptilia stigmatella Fabricius, 1781, in order to demonstrate that the study of historic and fragile type specimens and diagnosis of their internal morphological characters becomes possible by applying new and non-destructive technology

Prevalence and associated factors of HIV infection among pregnant women attending antenatal care at the Yaoundé central hospital

Background: HIV infection affects millions of people worldwide, especially in sub-Saharan Africa. Transmission occurs by several means including the transmission from mother to child. The objective of this study was to determine the prevalence and factors associated with HIV infection in women attending antenatal care at the Yaoundé Central Hospital.Methods: We conducted an analytical cross-sectional study at the Obstetrics and Gynecologic Unit of the Yaoundé Central Hospital from 6th October 2015 to 30th June 2016. The sampling was consecutive. We included 360 pregnant women. Testing was done by a sensitive test and a specific test if the first was positive. Data analysis was done through Excel 2007 software EpiData Analysis Version 3.2 and STATA version 12.0 (Texas USA 2001). Statistical significance was accepted for a value of P <0.05.Results: The average age of our population was 27.99±5.63 years, ranging from 15 and 47 years. HIV prevalence in this population was 13.1% (47/360). Factors associated with HIV were the primary level of study (OR=7.97; 95% CI=2.23 to 28.49, P=0.001) and multiple sexual partners (OR=4.82; CI 95%=2.24 to 10.38, P=0.002).Conclusions: HIV prevalence in pregnant women at the Maternity of HCY is 13.1%. The low level of education and multiple sexual partners were significantly associated with HIV infection. We suggest the education of the girls who is a key factor in the empowerment of women

Risk factors of intrauterine fetal death: a case control study at the maternity of Yaoundé Central Hospital

Background: Intrauterine fetal death (IUFD) is the death before the beginning of the work of the fetus from the 28th week of pregnancy or a fetus of weight greater than or equal to 1000g. It occurs in 98% in poor countries, particularly in sub-Saharan Africa. The aim of this study was to identify the risk factors for IUFD in low-income countries.Methods: All the women with preeclampsia from 30 weeks onwards were enrolled in the study. The umblical artery (UA) Systolic-diastolic (S/D) ratio >2 standard deviation (SD) or UA-pulsatility index (PI) and UA-resistive index (RI) >2 SD were taken as abnormal. The middle cerebral artery (MCA) was visualised and cerebroumblical PI ratio calculated. MCA-RI<2SD was taken as abnormal.Results: Independent risk factors for IUFD are age over 30 years (ORa = 2.1, P = 0.052), (ORa = 2.4497, p = 0.01), household occupation (ORa = 2.0097, p = 0.0282), hypertension disorders (ORa = 2.11, p = 0.0176), antepartal haemorrhage (ORa = 3.9635, p = 0.000), multiparity (ORa = 13.3089, p = 0.0056).Conclusions: The main risk factors for IUFD identified in our study are maternal age greater than 30 years, hypertension, antepartal haemorrhage, multiparity, and the household profession. Any pregnant woman who has one of these factors should be follow-up closely during pregnancy with a weekly assessment of fetal well-being by the 28th week

Enhanced Sludge Processing of HLW: Hydrothermal Oxidation of Chromium, Technetium, and Complexants by Nitrate

The objective of this project is to develop the scientific basis for hydrothermal separation of chromium from High Level Waste (HLW) sludges. Our worked is aimed at attaining a fundamental understanding of chromium speciation, oxidation/reduction and dissolution kinetics, reaction mechanisms, and transport properties under hydrothermal conditions in both simple and complex salt solutions that will ultimately lead to an efficient chromium leaching process
