A new alien parasite, Aclees sp. cf. foveatus (Coleoptera: Curculionidae), is causing considerable crop losses and deaths in many Italian fig (Ficus carica L.) tree nurseries and orchards and it is quickly spreading in central Italy. The adult and larval stages of this weevil are closely related to t he fig tree. To date, no phytosanitary products are registered for fig against this insect, so if this pest is not systematically managed, fig trees could be decimated. A commercial organic product, LaserTM, widely used on other crops, was used to assess its effectiveness on the adult stage of this weevil. In the first trial, the concentration recommended on the label for other fruit trees was used and compared with the control (only water), while in the second trial a comparison between the label concentration and the half was tested. Mortality of the adults was recorded in the following 3-4 days after treatment. A very high adult mortality was recorded when LaserTM was applied, even at lowest concentrations, and damages (erosion) on the sycons were strongly reduced compared to the control. The tested commercial product is very effective in controlling this pest and can represent a possible solution by significantly reducing the adult population.

Hypertension is a major contributor to the cardiovascular morbidity and mortality in industrialized countries. The recent reports suggest that hypertension is rapidly increasing in developing countries like India. Non-communicable diseases (NCDs) are the leading causes of death globally and also the leading cause of adult mortality and morbidity worldwide now days. The NCD like hypertension is emerging as a major health problem in India with increasing prevalence signicantly in both urban and rural population. The objectives of the study were to nd out the prevalence of hypertension and its association with socio-demographic factors among the study subjects, if any. A community-based cross-sectional study was conducted in rural communities of Kanti block, Muzaffarpur, Bihar from May, 2020 to April, 2021. We studied among 671 individuals, aged 21 years or above of both sexes except pregnant and seriously ill subjects. The data were collected about education, type of family, family history of hypertension, income etc. The overall prevalence of hypertension was 25.7% (male 21.7% and female 29.8%). Prevalence increased with increase in age group. Muslim religion, less education and sedentary life styles were found to be signicantly associated with hypertension; while socio-economic status had no association with hypertension. Summary: The prevalence of hypertension in the rural population was found to be on the higher side compared to previous reports from India. Strong public health measures need to be seriously implemented to combat hypertension and its consequences.

The ecology of a natural population of Dacus tryoni is being studied at an orchard near Sydney, N.S.W. Changes in numbers observed during a single year are described and discussed. Estimates of pupal numbers were based on the weekly total pupal production of a random sample of the fruit trees in the orchard. Parameters of the adult population were measured by means of mark-recapture sampling and analysed by means of three mathematical models. Discrepancies between some of the estimates of numbers given by these models are explained by extensive adult emergence at those times, and the lower survival factors of the young adults. Evidence for the random sampling of adults is presented. The decline of the population towards the end of the season was brought about mainly by (1) high pupal mortality, (2) cessation of pupal production due to diminution and disappearance of larval food, (3) a marked decline in the number of gravid females, apparently in response to diminishing oviposition sites, and (4) a high rate of loss of young adults, presumably by emigration. There was no evidence of overcrowding.

Measles continue to be a major public health issue worldwide with high morbidity and mortality rates. The disease is still endemic in Europe and during 2017 a vast outbreak was described in Italy, Romania and Hungary, which led to thousands of new cases and several deaths. In Italy, 3931 confirmed cases of measles were reported to the Italian national surveillance system from many Italian administrative regions; Lazio, in central Italy, exhibited the highest number of infected patients 1322 (33.63%) and as well as the highest incidence. In this study, we describe the results of a retrospective analysis, carried out during 2016 and 2017, concerning the measles antibody prevalence in patients and healthcare workers attending the Sant’Andrea Hospital of Rome (Lazio). A total of 94 patients (median 30 years of age) were screened in 2016, and 316 (median 40 years of age) during 2017, with an increase of 236% compared to previous year. During 2017, 41 confirmed cases of measles were reported while none in 2016 (P<0.007), and we found a suboptimal immunization coverage in our cohort of patients. Furthermore, measles surveillance of Sant’Andrea healthcare workers during the study period involved 208 personnel units (median >47 years of age) and only one confirmed measles infection was recorded in 2017. These results suggest that there is still an unvaccinated portion of the adult population, who sustain the endemic circulation of measles in Italy. In addition to reach herd immunization on children of 2 years old, catch-up vaccination campaign targeting adult population in Italy and other European countries needs to be implemented to prevent future measles outbreak.

O presente trabalho teve como objetivo avaliar o desempenho propagativo de estacas semilenhosas de variedades de figueira, com o uso de ácido indolbutírico. As variedades avaliadas foram Roxo de Valinhos, White Genova, PI – 189 e Troiano e a dosagem empregada do ácido indolbutírico foi 2000 mg L-1. O delineamento experimental utilizado foi o inteiramente ao acaso, em esquema fatorial 4 x 2 (variedades x com e sem aplicação do regulador vegetal), com cinco repetições e dez estacas por parcela experimental. Foram avaliadas a porcentagem de estacas vivas, de estacas enraizadas e de estacas brotadas, número de brotos, comprimento da maior raiz (cm), número de folhas, volume da raiz (cm3), peso seco da raiz (mg) e peso seco das folhas (mg). As estacas que não receberam a aplicação do regulador vegetal tiveram maior porcentagem de estacas vivas, enraizadas e brotadas, com exceção das variedades Roxo de Valinhos e Troiano, que não apresentaram diferença na aplicação. Mediante esses resultados, foi possível concluir que não é recomendado o uso do ácido indolbutírico para essas variedades, na época de coleta das estacas correspondente ao mês de agosto.PALAVRAS-CHAVE: Ficus carica L., propagação, regulador de crescimento FIG TREE VARIETIES CUTTINGS ROOTING USING INDOLEBUTYRIC ACID ABSTRACT: The present study aimed to evaluate the propagative performance of fig trees cuttings with application of indolebutyric acid (IBA).

ABSTRACT The use of protected environment in horticulture has been increasingly used as it provides increased precocity and productivity, in addition to produce outside the normal growing season. Both woody species such as herbs are possible to cultivate in this environment. However fruit plants occupy large spaces with a short production period. The study aimed to test whether strawberry genotypes present different production peaks in cultivated environment with fig trees. The treatments consisted of strawberry cultivars Aromas, Albion, Camino Real, Camarosa and Ventana distributed in delineation of randomized blocks with four replications and with a population of 10 plants m-2. It was recorded precocity in cultivars Albion, Camarosa and Ventana, because they started flowering at 63 days after planting. Aromas and Camino Real were characterized as late. Aromas achieved greater total number of fruit, but with a lower percentage of commercial fruits in relation to the other cultivars. Peak production for all cultivars was found when there was an accumulation 2008 °C day -1, corresponding to the month of November. There were differences in performance production between strawberry cultivars conducted in the environment with fig tree, with different production peaks.

Abstract: This article aims to assess the sociodemographic and epidemiological factors associated with AIDS and tuberculosis-HIV coinfection mortality in the Chilean adult population between 2000 and 2017. This is a retrospective observational study, evaluating the incidence density of TB-HIV coinfection mortality in the population over 14 years of age. We used data from the Chilean AIDS Cohort database, 17,512 people enrolled in highly active antiretroviral therapy in the public health system in Chile. The Kaplan-Meier survival function and Cox regression were applied. Incidence density of 0.05 for 39,283 person-years for mortality with TB-HIV coinfection was recorded, with an increase in new cases in people living with AIDS among Aymara and Mapuche indigenous populations. Risk factors included CD4 < 500 cells/mm3 (HR = 3.2; 95%CI: 2.2-4.9), viral load at the start of treatment > 10,000 copies/uL (HR = 1.3; 95%CI: 1.2-1.6). Having high school or higher education (HR = 0.76; 95%CI: 0.6-0.9) is a protective factor for mortality for coinfection. Mortality was concentrated in TB-HIV coinfected people with increasing mortality among women and indigenous populations. The paper contributes to the growing recognition of the role of social determinants in disease outcomes, and the requirement to improve community-focused and community-based testing, sex education in schools, and structural interventions to reduce the adult mortality in Chilean population.

Abstract Fig tree (Ficus carica L.) stands out due to its range of cultivation and easy adaptation to diverse edaphoclimatic conditions. In addition to its adaptability, fruits have nutraceutical characteristics and are used in industry and for fresh consumption, widely appreciated by the world cuisine. Due to lack of manpower and phytosanitary problems, the area planted in Brazil has decreased recently. To overcome these obstacles, the production of quality seedlings is the first step to obtaining productive and healthy orchards. Therefore, the aim of the present literature review was to gather data referring to advances in research related to the fig tree propagation. Currently, the methods found for fig tree propagation consist of seedling production, where entomophilic or vegetative pollination occurs. Commercially, the propagation method by cutting is still the most used for this crop; however, other methods can also be used, such as the use of burrs or plunging and grafting techniques and tissue culture. Although there is a diversity of propagation methods and new technologies being developed, cuttings remain the most feasible method. In addition, obtaining healthy and quality seedlings is one of the main problems currently found in ficiculture, since, in addition to the scarcity of studies related to propagation, the use of resistant cultivars and pathogen-free substrates should be prioritized due to susceptibility of fig trees to nematodes. Thus, further studies should be carried out in order to seek new information on the cultivars most adapted to each locality, as well as improvements in propagation and cultivation techniques.
