A preliminary check-list of the Chalcidoidea (Hymenoptera) of the Maltese Islands

A list of 147 species of Chalcidoidea from the Maltese Islands is presented 73 of which are here reported for the first time from this territory. They belong to 15 families as follows: Agaonidae (3); Aphelinidae (20 including 3 new records); Azotidae (1 new record); Chalcididae (3 new records); Encyrtidae (23 including 13 new records); Eulophidae (35 including 19 new records); Eupelmidae (7 including 2 new records); Eurytomidae (5 including 4 new records); Leucospidae (4); Mymaridae (2); Ormyridae (1 new record); Pteromalidae (33 including 21 new records); Signiphoridae (2); Tetracampidae (1 new record); Torymidae (7 including 5 new records). Out of the 73 new records, 55 were exclusively found in Malaise trap samples at Verdala Palace near Buskett, a semi-natural wooded area dominated by Pinus halepensis. Thirty species mentioned in the present study were reared from plant-galls, either during the present study or in former studies pertaining to Malta. Of these 8 are gall inducers and the rest are primary or secondary parasitoids of the gall inducers. This list must represent only a small proportion of the actual species richness expected to be found in the Maltese Islands since absolutely no field work was carried out in other diverse and potentially rich habitats, such as steppe, garigue, maquis, coastal habitats and valley systems, present on these islands.peer-reviewe

Saltbush-associated Asphondylia species (Diptera: Cecidomyiidae) in the Mediterranean Basin and their chalcidoid parasitoids (Hymenoptera: Chalcidoidea)

Numerous species of gall midges (Diptera: Cecidomyiidae) have been recorded from saltbush (Chenopodiaceae: Atriplex) around the world but only 11 of them belong to the large cecidomyiid genus Asphondylia. Of these, two species were de-scribed in the late 19th century from complex bud galls on Atriplex halimus in the Mediterranean Basin. In the present study Asphondylia punica is redescribed, A. conglomerata is synonymized with it, and Asphondylia scopuli is described from Atriplex lanfrancoi, an endemic plant to the Maltese Islands. Descriptions are accompanied by information about the galls and life history of the gall midges, and a review of the parasitic Hymenoptera associated with A. scopuli is provided. Four species of parasitoids were found and attributed to the families Eurytomidae, Pteromalidae, Eupelmidae and Eulophidae, of which the pteromalid Mesopolobus melitensis is described as new.peer-reviewe

Hymenoptera Chalcidoidea inhabiting galls of Cynipidae in Jordan

Twenty-three species of Chalcidoidea (5 Eurytomidae, 4 Torymidae, 2 Ormyridae, 5 Pteromalidae and 7 Eulophidae) are recorded as regular members of the parasitoid fauna inhabiting galls of Cynipidae in Jordan. The occurrence of three additional species, probably only facultatively associated with cynipid galls, is noted. Twenty-two out of the total 26 species were previously unrecorded in the country, while 13 of them are also new for the entire Middle East. Eighteen new host records were detected, together with 24 new plant-parasitoid associations. The biology of each species is briefly commented upon, as well as the presence of a host-related colour variation in some species

Two hymenopteran egg sac associates of the tent-web orbweaving spider, Cyrtophora citricola (Forskål, 1775) (Araneae, Araneidae)

We report the discovery of two wasp species emerging from egg sacs of the spider Cyrtophora citricola (Forskål 1775) collected from mainland Spain and the Canary Islands. We identify one as Philolema palanichamyi (Narendran 1984) (Hymenoptera, Eurytomidae) and the other as a member of the Pediobius pyrgo (Walker 1839) species group (Hymenoptera, Eulophidae). This is the first report of Philolema in Europe, and the first documentation of hymenopteran egg predators of C. citricola. The latter finding is particularly relevant, given the multiple invasive populations of C. citricola in the Americas and the Caribbean, where neither egg sac predation nor parasitism is known to occur. We describe rates of emergence by Ph. palanichamyi from spider egg sacs collected from the southern coast of Spain and estimate sex ratios and body size variation among males and females. We also re-describe Ph. palanichamyi based on the female holotype and male paratype specimens

Family planning use and fertility desires among women living with HIV in Kenya.

BACKGROUND: Enabling women living with HIV to effectively plan whether and when to become pregnant is an essential right; effective prevention of unintended pregnancies is also critical to reduce maternal morbidity and mortality as well as vertical transmission of HIV. The objective of this study is to examine the use of family planning (FP) services by HIV-positive and HIV-negative women in Kenya and their ability to achieve their fertility desires. METHODS: Data are derived from a random sample of women seeking family planning services in public health facilities in Kenya who had declared their HIV status (1887 at baseline and 1224 at endline) and who participated in a longitudinal study (the INTEGRA Initiative) that measured the benefits/costs of integrating HIV and sexual/reproductive health services in public health facilities. The dependent variables were FP use in the last 12 months and fertility desires (whether a woman wants more children or not). The key independent variable was HIV status (positive and negative). Descriptive statistics and multivariate logistic regression analysis were used to describe the women's characteristics and to examine the relationship between FP use, fertility desires and HIV status. RESULTS: At baseline, 13 % of the women sampled were HIV-positive. A slightly higher proportion of HIV-positive women were significantly associated with the use of FP in the last 12 months and dual use of FP compared to HIV-negative women. Regardless of HIV status, short-acting contraceptives were the most commonly used FP methods. A higher proportion of HIV-positive women were more likely to be associated with unintended (both mistimed and unwanted) pregnancies and a desire not to have more children. After adjusting for confounding factors, the multivariate results showed that HIV-positive women were significantly more likely to be associated with dual use of FP (OR = 3.2; p < 0.05). Type of health facility, marital status and household wealth status were factors associated with FP use. Factors associated with fertility desires were age, education level and household wealth status. CONCLUSIONS: The findings highlight important gaps related to utilization of FP among WLHIV. Despite having a greater likelihood of reported use of FP, HIV-positive women were more likely to have had an unintended pregnancy compared to HIV-negative women. This calls for need to strengthen family planning services for WLHIV to ensure they have better access to a wide range of FP methods. There is need to encourage the use of long-acting reversible contraceptive (LARC) to reduce the risk of unintended pregnancy and prevention of vertical transmission of HIV. However, such policies should be based on respect for women's right to informed reproductive choice in the context of HIV/AIDS. TRIAL REGISTRATION: NCT01694862

Use of HIV counseling and testing and family planning services among postpartum women in Kenya: a multicentre, non-randomised trial.

BACKGROUND: Addressing the postnatal needs of new mothers is a neglected area of care throughout sub-Saharan Africa. The study compares the effectiveness of integrating HIV and family planning (FP) services into postnatal care (PNC) with stand-alone services on postpartum women's use of HIV counseling and testing and FP services in public health facilities in Kenya. METHODS: Data were derived from samples of women who had been assigned to intervention or comparison groups, had given birth within the previous 0-10 weeks and were receiving postnatal care, at baseline and 15 months later. Descriptive statistics describe the characteristics of the sample and multivariate logistic regression models assess the effect of the integrated model of care on use of provider-initiated testing and counseling (PITC) and FP services. RESULTS: At the 15-month follow-up interviews, more women in the intervention than comparison sites used implants (15 % vs. 3 %; p < 0.001), while injectables were the most used short-term method by women in both sites. Women who wanted to wait until later to have children (OR = 1.3; p < 0.01; 95 % CI: 1.1-1.5), women with secondary education (OR = 1.2; p < 0.05; 95 % CI: 1.0-1.4), women aged 25-34 years (OR = 1.2; p < 0.01; 95 % CI: 1.1-1.4) and women from poor households (OR = 1.6; p < 0.001; 95 % CI: 1.4-1.9) were associated with FP use. Nearly half (47 %) and about one-third (30 %) of mothers in the intervention and comparison sites, respectively, were offered PITC. Significant predictors of uptake of PITC were seeking care in a health center/dispensary relative to a hospital, having a partner who has tested for HIV and being poor. CONCLUSIONS: An integrated delivery approach of postnatal services is beneficial in increasing the uptake of PITC and long-acting FP services among postpartum women. Also, interventions aimed at increasing male partners HIV testing have a positive effect on the uptake of PITC and should be encouraged. TRIAL REGISTRATION: ClinicalTrials.gov NCT01694862

Functional mapping of quantitative trait loci (QTLs) associated with plant performance in a wheat MAGIC mapping population

In crop genetic studies, the mapping of longitudinal data describing the spatio-temporal nature of agronomic traits can elucidate the factors influencing their formation and development. Here, we combine the mapping power and precision of a MAGIC wheat population with robust computational methods to track the spatio- temporal dynamics of traits associated with wheat performance. NIAB MAGIC lines were phenotyped throughout their lifecycle under smart house conditions. Growth models were fitted to the data describing growth trajectories of plant area, height, water use and senescence and fitted parameters were mapped as quantitative traits. Trait data from single time points were also mapped to determine when and how markers became and ceased to be significant. Assessment of temporal dynamics allowed the identification of marker-trait associations and tracking of trait development against the genetic contribution of key markers. We establish a data-driven approach for understanding complex agronomic traits and accelerate research in plant breeding

Transient Midventricular Ballooning Syndrome A New Variant

We describe a new variant of transient left ventricular (LV) ballooning in North American Caucasian patients in which only the midventricle is affected. The patients described in this case series initially presented with emotional or physical stress and had similarities to transient apical ballooning syndrome; however, this variant is unique in that the transient ballooning involves the midventricle with hypercontractility of the apical and basal segments. The presentation, clinical features, and transient nature of the reported cases in this series are similar to transient LV apical ballooning and suggest a shared pathophysiologic etiology. Sparing of the apical segment with involvement of midventricle only supports etiologies not related to an epicardial coronary artery distribution. Although the pathophysiologic mechanism of the transient ventricular ballooning syndromes and other cases of catecholamine-associated transient ventricular dysfunction are not well understood, the emergence of this new variant raises further questions in the understanding of the “brain-heart” relationship
