An evaluation of orange and clear traps with pear ester to monitor codling moth (Lepidoptera: Tortricidae) in apple orchards

Barros-Parada, W (Barros-Parada, Wilson)[ 1 ] ; Knight, AL (Knight, Alan L.)[ 2 ] ; Basoalto, E (Basoalto, Esteban)[ 3 ] ; Fuentes-Contreras, E (Fuentes-Contreras, Eduardo)[ 1 ] Univ Talca, Fac Ciencias Agr, Casilla 747, Talca, ChileStudies were conducted to evaluate the use of several trap-lure combinations to improve the monitoring of codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), in apple, Mains domestica Bordk. The treatments involved the use of clear, orange, and white traps baited with one or more of the following attractants: the major sex pheromone component of the codling moth, (E, E)-8,10-dodecadien-1-ol (codlemone, PH); a primary volatile constituent of ripe pear, ethyl (E, Z)-2,4-decadienoate (pear ester, PE); and acetic acid (AA). The studies were conducted in an orchard treated with sex pheromone dispensers in Washington State (USA) and in four untreated orchards in the Maule Region (Chile). In Washington State, the PE+AA lures caught more females than the PE+PH lure in both the clear and orange traps. The clear traps caught more female moths than the orange traps when each trap was baited with the PE+PH lure. The two lures caught similar total numbers of moths across trap colors. The clear traps baited with PE+PH caught significantly more total moths than the orange traps baited with PE+AA. In Chile, the clear traps baited with PE+AA caught more females than the orange traps baited with PE+PH over both moth flights during two field seasons. The white traps baited with PH and the orange traps baited with PE+PH caught similar total numbers of moths in three of the four flight periods. The clear trap baited with PE+AA caught significantly fewer moths than the two treatments that included a PH lure in two of the four flight periods. These data suggest that the adoption of clear delta traps with PE-I-AA lures would allow growers to better track the seasonal population dynamics of female codling moths

Discriminación de género en el mercado laboral colombiano

This document analyzes the differences in income by gender in Colombia for the year 2018 and other determinants that affect the income of the heads of households. Theoretical elements that define the wage differences are addressed, such as the Blinder-Oaxaca decomposition and the Miner equation, which are complemented by the theory of discrimination. Methodologically, the information reported in the statistics department DANE’s quality of life survey is used. A descriptive statistical analysis and an econometric model are carried out. On average, the female gender head of the household in Colombia earns less than her male counterparts. The most significant differences correspond to the levels of education, which can have implications in other social indicators such as poverty.El presente documento hace un análisis de las diferencias de ingresos por género en Colombia para el año 2018 junto con otros determinantes que afectan los ingresos de los jefes de hogar. Se abordan los elementos teóricos que definen las diferencias salariales tales como la descomposición Blinder-Oaxaca y la ecuación de Miner, lo que se complementa con la teoría de la discriminación. Metodológicamente se parte de la información reportada en la encuesta de calidad de vida del departamento de estadísticas DANE, se realiza un análisis estadístico descriptivo y un modelo econométrico. Se encuentra que en promedio el género femenino cabeza de hogar en Colombia devenga menos que sus pares masculinos, así como que las mayores diferencias corresponden a los niveles de educación, lo que a su vez puede tener implicaciones en términos de otros indicadores sociales como el de la pobreza

Efficiency of HIV services in Nigeria: Determinants of unit cost variation of HIV counseling and testing and prevention of mother-to-child transmission interventions

Background Like most countries with a substantial HIV burden, Nigeria continues to face challenges in reaching coverage targets of HIV services. A fundamental problem is stagnated funding in recent years. Improving efficiency is therefore paramount to effectively scale-up HIV services. In this study, we estimated the facility-level average costs (or unit costs) of HIV Counseling and Testing (HCT) and Prevention of Mother-to-Child Transmission (PMTCT) services and characterized determinants of unit cost variation. We investigated the role of service delivery modalities and the link between facility-level management practices and unit cost variability along both services’ cascades. Methods We conducted a cross-sectional, observational, micro-costing study in Nigeria between December 2014 and May 2015 in 141 HCT, and 137 PMTCT facilities, respectively. We retrospectively collected relevant input quantities (personnel, supplies, utilities, capital, and training), input prices, and output data for the year 2013. Staff costs were adjusted using time-motion methods. We estimated the facility-level average cost per service along the HCT and PMTCT service cascades and analyzed their composition and variability. Through linear regressions analysis, we identified aspects of service delivery and management practices associated with unit costs variations. Results The weighted average cost per HIV-positive client diagnosed through HCT services was US $130. The weighted average cost per HIV-positive woman on prophylaxis in PMTCT services was US$858. These weighted values are estimates of nationally representative unit costs in Nigeria. For HCT, the facility-level unit costs per client tested and per HIV-positive client diagnosed were US$30 and US$1,364, respectively; and the median unit costs were US$17 and US$245 respectively. For PMTCT, the facility-level unit costs per woman tested, per HIV-positive woman diagnosed, and per HIV-positive woman on prophylaxis were US$46, US$2,932, and US$3,647, respectively, and the median unit costs were US$24, US$1,013 and US$1,448, respectively. Variability in costs across facilities was principally explained by the number of patients, integration of HIV services, task shifting, and the level of care. Discussion Our findings demonstrate variability in unit costs across facilities. We found evidence consistent with economies of scale and scope, and efficiency gains in facilities implementing task-shifting. Our results could inform program design by suggesting ways to improve resource allocation and efficiently scale-up the HIV response in Nigeria. Some of our findings might also be relevant for other settings

Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study

Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001). Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication

Monitoring Oriental Fruit Moth and Codling Moth (Lepidoptera: Tortricidae) With Combinations of Pheromones and Kairomones

Experiments were conducted in North and South America during 2012-2013 to evaluate the use of lure combinations of sex pheromones (PH), host plant volatiles (HPV), and food baits in traps to capture the oriental fruit moth, Grapholita molesta (Busck) and codling moth, Cydia pomonella (L.) in pome and stone fruit orchards treated with sex pheromones. The combination of the sex pheromone of both species (PH combo lure) significantly increased G. molesta and marginally decreased C. pomonella captures as compared with captures of each species with either of their sex pheromones alone. The addition of a HPV combination lure ((E,Z)-2,4-ethyl decadienoate plus (E)-β-ocimene) or acetic acid used alone or together did not significantly increase the catch of either species in traps with the PH combo lure. The Ajar trap baited with terpinyl acetate and brown sugar (TAS bait) caught significantly more G. molesta than the delta trap baited with PH combo plus acetic acid in California during 2012. The addition of a PH combo lure to an Ajar trap significantly increased catches of G. molesta compared to the use of the TAS bait or PH combo lure alone in 2013. Female G. molesta were caught in TAS-baited Ajar traps at similar levels with or without the use of additional lures. Ajar traps baited with the TAS bait alone or with (E)-β-ocimene and/or PH combo lures caught significantly fewer C. pomonella than delta traps with sex pheromone alone. Ajar traps with 6.4-mm screened flaps caught similar numbers of total and female G. molesta as similarly baited open Ajar traps, and with a significant reduction in the catch of nontargets. Broader testing of HPV and PH combo lures for G. molesta in either delta or screened or open Ajar traps is warranted.Keywords: Cydia pomonella, Grapholita molesta, Apple, Peac
