Mating disruption of Ostrinia furnacalis (Guenée) (Lepidoptera: Crambidae) with its sex pheromone has not been commonly used in NE China due to a lack of information about optimal sex pheromone dosages and the density of release points required in the field. During 2014-2016, first, the two active pheromone ingredients were evaluated in the laboratory alone at ca. 2.5-5.0 mg, or in combination at 0.2-6.0 mg, to disrupt male O. furnacalis mating behaviors. Then, mating disruption areas, with radii of <8...

Picky eating behavior is prevalent among toddlers and may negatively impact their growth and development. This article summarizes the correlates of picky eating and food neophobia in young children, which were identified using a socio-ecological framework. A literature search was conducted in 4 electronic databases. Inclusion criteria were English-language peer-reviewed publications that investigated correlate(s) of picky eating or food neophobia in children aged ≤30 months. Correlates were categorized into 4 levels: cell, child, clan (family), and community/country...

People who inject drugs (PWID) and HIV-infected men who have sex with men (MSM) are key risk groups for HCV transmission. Mathematical modeling studies can help elucidate what level and combination of prevention intervention scale-up is required to control or eliminate epidemics among these key populations. We discuss the evidence surrounding HCV prevention interventions and provide an overview of the mathematical modeling literature projecting the impact of scaled-up HCV prevention among PWID and HIV-infected MSM...

Peers are thought to increase adolescents' risk-taking behavior, at least in part, by heightening their sensitivity to rewards. In this study, we investigate whether the effect of peers on late adolescent males is exacerbated when youth are cognitively fatigued, a state characterized by weakened cognitive control and heightened orientation toward rewards, and well established as a factor that compromises decision making. We hypothesized that fatigued adolescents' top-down regulation of reward-related impulses may be compromised, thereby potentially amplifying the effect of peers on reward- and risk-seeking behavior...

OBJECTIVES: The US shows a distinct health disadvantage when compared to other high-income nations. A potential lever to reduce this disadvantage is to improve the health situation of lower socioeconomic groups. Our objective is to explore how the considerable within-US variation in health inequalities compares to the health inequalities across other Western countries. METHODS: Representative survey data from 44 European countries and the US federal states were obtained from the fourth wave of the European Values Study (EVS) and the 2008 wave of the Behavioral Risk Factor Surveillance System...

BACKGROUND AND AIMS: Sending and receiving sexually suggestive or explicit images or texts (sexting) have been shown to be associated with health risk behaviors but literature about this phenomenon is scarce in Nigeria. This study looked at the prevalence, predictors, and associated sexual risk behaviors of sexting among postsecondary school young persons in Ibadan, Nigeria. METHODS: This was a cross-sectional study using a self-administered questionnaire. Data were obtained for sociodemographic characteristics and sexual orientation, sexting behavior, personality assessment (using the International Personality Item Pool Big-Five factor markers), indicators for problematic phone use (using Mobile Phone Problem Use Scale), and sexual behavior...

Fred C Pampel
Though many studies have described societal-wide changes in tolerance for sexual behaviors outside marriage, few have examined how the social distribution of tolerant attitudes has changed. A diffusion-of-innovations approach predicts nonlinear change in the distribution: high SES groups adopt the attitudes first, which produces a positive relationship, but diffusion to other SES groups subsequently weakens the association with SES. I test this argument using the General Social Survey from 1973 to 2014 to compare the SES determinants of attitudes toward premarital sex, extramarital sex, same-gender sex, and teenage sex across 86 cohorts born from around 1900 to 1985...

BACKGROUND: HIV vaccine trial participants may engage in behavioral risk compensation due to a false sense of protection. We conducted an ancillary study of an HIV Vaccine Trials Network (HVTN) vaccine efficacy trial to explore risk compensation among trial participants compared to persons who were willing to participate but ineligible based on previous exposure to the Ad5 virus (Ad5+) across three timepoints. METHODS: Participants were drawn from the Atlanta, GA site of the HVTN 505 vaccine trial...

Moulages are three-dimensional colorful replicas of body parts with particular expressions of ailments. Historically, by operating a transition between illness and disease, moulages were a powerful tool in the consolidation of the medical specialty of dermatovenereology. Yet moulages are not solely an objectification of biological processes suitable for medical teaching; they also activate non-medical cognitions and emotions about life, death, behavior and morality that are rooted in the history of the art of wax modeling...

Vasomotor symptoms (VMS, or hot flashes) plague millions of reproductive age men and women who have natural or iatrogenic loss of sex steroid production. Many affected individuals are left without treatment options because of contraindications to hormone replacement therapy and the lack of equally effective non-hormonal alternatives. Moreover, development of safer, more effective therapies has been stymied by the lack of an animal model that recapitulates the hot flash phenomenon and enables direct testing of hypotheses regarding the pathophysiology underlying hot flashes...

Several studies suggest that the increase in sexually transmitted infections (STIs) among men who have sex with men (MSM) could be due, in part, to human immunodeficiency virus (HIV) risk reduction strategies, which include engaging in oral sex over anal sex. The aims of this study were to evaluate oral sex behaviors and STI diagnoses and to investigate the potential dual role of oral sex as being protective for HIV, yet perpetuating STI transmission among MSM. We analyzed records from 871 MSM presenting to the Rhode Island STI Clinic between 2012 and 2015...

OBJECTIVE: Caffeinated alcoholic beverage (CAB) use is associated with a range of substance-related problems. The majority of prior research on CABs is based on cross-sectional and retrospective reports, which do not account for intraindividual differences in use and may be subject to recall biases. The current research used a daily diary, within-subjects design to compare days where individuals simultaneously mixed alcohol with caffeine (CAB days) and days where individuals drank other types of alcohol (non-CAB days) on alcohol use outcomes...

Research examining pubertal timing effects on psychopathology has emphasized that a subset of adolescents, particularly females, who experience early pubertal maturation relative to their peers appear to be at increased risk for psychopathology. The aims of the current meta-analysis were (a) to quantify the magnitude of early pubertal timing effects on psychopathology, (b) to examine potential moderators of pubertal timing effects (sex, psychopathology domain, sample composition, measurement method, and mean sample age), and (c) to examine findings in relation to hypotheses in the extant literature explicating differential pubertal timing effects for early versus late youth and males versus females...

Many insect species use multi-component sex pheromones to discriminate among potential mating partners [1-5]. In moths, pheromone blends tend to be dominated by one or two major components, but behavioral responses are frequently optimized by the inclusion of less abundant minor components [6]. An increasing number of studies have shown that female insects use these chemicals to convey their mating availability to males, who can assess the maturity of females and thus decide when to mate [7, 8]. However, little is known about the biological mechanisms that enable males to assess female reproductive status...

Body temperature variation in response to acute stress is typically characterized by peripheral vasoconstriction and a concomitant increase in core body temperature (stress-induced hyperthermia). It is poorly understood how this response differs between species and within individuals of the same species, and how it is affected by the environment. We therefore investigated stress-induced body temperature changes in a non-model species, the Black-capped Chickadee, in two environmental conditions: outdoors in low ambient temperature (mean: -6...

OBJECTIVES: Body dysmorphic disorder (BDD) is characterized by repetitive behaviors and/or mental acts occurring in response to preoccupations with perceived defects or flaws in physical appearance. There are some similarities, but also important differences, between BDD and obsessive-compulsive disorder (OCD), not just in terms of core clinical symptoms, but possibly in the domain of perception. This study compared the nature and extent of perceptual anomalies in BDD versus OCD and health controls (HC), using a modified Mooney task...

PURPOSE: Young men who have sex with men (YMSM) are at disproportionate risk for HIV infection. Parental monitoring is protective against adolescent sexual risk behavior among heterosexual adolescents, yet it is unclear whether these findings generalize to YMSM. YMSM experience unique family dynamics during adolescence, including coming out to parents and parental rejection of sexual orientation. The present study examined how theoretically derived parental monitoring constructs were associated with sexual activity and sexual risk behaviors among YMSM...

Depression induced by stress is affected by sex, age and hormonal status of the animal and also by duration and type of the stressors. Moreover, higher prevalence of depression and comorbidities in women than men implies the need to include the sex variable in studies on animal models of depression. The present study was therefore initiated to evaluate the effect of sex and ovarian hormones on depression-like phenotypes in mice exposed to a 21-day Chronic Variable Mild Stress (CVMS) paradigm. Adult male, intact female and, ovariectomized (OVX) female mice exposed to CVMS displayed despair behavior, a depression-like phenotype, in all the groups...
