Farmed crickets (Orthoptera: Gryllidae) raised with dermestids (Coleoptera: Dermestidae) suffer from reduced and delayed growth, but not enough to explain reports of dramatic yield loss.

The mass production of insects for food and feed is an expanding North American industry. Facilities that mass rear insects are at risk of pest infestations because the optimal environmental conditions for rearing beneficial species may also support the development of pest species. Here, we present the first recorded results detailing the interactions between dermestids and farmed crickets.

Texas field crickets (Gryllus texensis) use visual cues to place learn but perform poorly when intra- and extra-maze cues conflict.

Central place foraging field crickets are an ideal system for studying the adaptive value of learning and memory, but more research is needed on ecologically relevant cognition in these invertebrates. Here, we test the visuospatial place learning of Texas field crickets (Gryllus texensis) in a radial arm maze. Our study expands previous work on G.

Tests of the positive and functional allometry hypotheses for sexually selected traits in the Jamaican field cricket.

Sexually selected traits, including threat signals, have been shown to scale steeply positively with body size because their exaggeration maximizes honest signalling. However, the functional allometry hypothesis makes the opposite prediction for some weapons: because the biomechanics of force applied in their use may favor relatively smaller size, sexually selected weapons may exhibit negative allometry. Tests of these ideas in insects have largely focused on holometabolous species, whose adult body size is entirely dependent on nutrients acquired during the larval stage.

Teaching animal behavior online: A primer for the pandemic and beyond.

Behavior courses face numerous challenges when moving to an online environment, as has been made necessary by the COVID-19 pandemic. These challenges occur largely because behavior courses, like most organismal biology courses, often stress experiential learning through laboratories that involve live animals, as well as a lecture component that emphasizes formative assessment, discussion, and critical thinking. Although online behavior courses may be remote, they can still be interactive and social, and designed with inclusive pedagogy.

The effects of commonly used anaesthetics on colour measurements across body regions in the poeciliid fish, Girardinus metallicus.

The effects of common anaesthetics on the hue, saturation and brightness measurements of the poeciliid fish Girardinus metallicus were investigated in two experiments. For both experiments the coloration of four body regions was measured from digital images of the same males obtained under three conditions: (1) control (in a water-filled chamber); (2) anaesthetised with MS-222; and (3) anaesthetised with eugenol (clove oil). In experiment 1 anaesthetised fish were photographed out of water.

Use of Asthma APGAR Tools in Primary Care Practices: A Cluster-Randomized Controlled Trial.

Purpose: The purpose of this study was to assess patient and practice outcomes after introducing the Asthma APGAR (Activities, Persistent, triGGers, Asthma medications, Response to therapy) tools into primary care practices.

Methods: We used a pragmatic cluster-randomized controlled design in 18 US family medicine and pediatric practices to compare outcomes in patients with persistent asthma aged 5 to 45 years after introduction of the Asthma APGAR tools vs usual care. Patient outcomes included asthma control, quality of life, and emergency department (ED), urgent care, and inpatient hospital visits.

Male crickets adjust their aggressive behavior when a female is present.

Communication in nature often occurs within a broad social network, as signals can be perceived by other individuals beyond the primary intended receiver. Because signals often contain information about the signaller's quality, receivers other than the primary intended receiver may use this information in future interactions with the signaller. As a result, individuals who adjust their behavior depending on who is present may experience a selective advantage.

Obesity, low levels of physical activity and smoking present opportunities for primary care asthma interventions: an analysis of baseline data from The Asthma Tools Study.

Background: Asthma prevalence, severity and outcomes are associated with various patient characteristics and lifestyle choices.

Aims: To identify potentially modifiable factors associated with poor asthma outcomes among US primary care patients.

Methods: Using baseline data from the Asthma Tools Study, we calculated cross-sectional frequencies of activity levels, smoking, secondhand smoke exposure and the presence of obesity, as well as rates of out-of-control asthma and asthma exacerbations.

Repeated depression screening during the first postpartum year.

Purpose: Postpartum depression (PPD) screening at 4 to 12 weeks' postpartum can improve outcomes for women when linked to in-practice management programs. The benefit of repeated PPD screening during the first year postpartum remains unclear.

Methods: We report a substudy of a large pragmatic trial of early PPD screening and practice management, the Translating Research into Practice for Postpartum Depression (TRIPPD) study.

Towards a synthesis of frameworks in nutritional ecology: interacting effects of protein, carbohydrate and phosphorus on field cricket fitness.

Phosphorus has been identified as an important determinant of nutrition-related biological variation. The macronutrients protein (P) and carbohydrates (C), both alone and interactively, are known to affect animal performance. No study, however, has investigated the importance of phosphorus relative to dietary protein or carbohydrates, or the interactive effects of phosphorus with these macronutrients, on fitness-related traits in animals.

Depressive symptoms and access to mental health care in women screened for postpartum depression who lose health insurance coverage after delivery: findings from the Translating Research into Practice for Postpartum Depression (TRIPPD) effectiveness study.

Objective: To determine the impact of losing health insurance coverage on perceived need for and access to mental health care in women screened for postpartum depression (PPD) in primary care settings.

Patients And Methods: The study sample included 2343 women enrolled in a 12-month, multisite, randomized trial that compared clinical outcomes of a comprehensive PPD screening and management program with usual care (March 1, 2006, through August 31, 2010). Screening for PPD occurred at the first postpartum visit (5-12 weeks) using the Edinburgh Postnatal Depression Scale followed by the 9-item Patient Health Questionnaire.

How male sound pressure level influences phonotaxis in virgin female Jamaican field crickets (Gryllus assimilis).

Understanding female mate preference is important for determining the strength and direction of sexual trait evolution. The sound pressure level (SPL) acoustic signalers use is often an important predictor of mating success because higher sound pressure levels are detectable at greater distances. If females are more attracted to signals produced at higher sound pressure levels, then the potential fitness impacts of signalling at higher sound pressure levels should be elevated beyond what would be expected from detection distance alone.

Comparing the Asthma APGAR system and the Asthma Control Test™ in a multicenter primary care sample.

Objective: To compare asthma control assessment using the Asthma APGAR system, a tool developed by primary care clinicians, in a multicenter primary care sample with the Asthma Control Test (ACT™)/Childhood Asthma Control Test (CACT™), a tool developed by asthma specialists.

Patients And Methods: This is a substudy of a multicenter, randomized, controlled pragmatic trial that tests the effectiveness of the Asthma APGAR system in primary care practices. As part of the study, enrolled patients completed both the ACT™/CACT™ and the Asthma APGAR system between March 1, 2011, and December 31, 2011.

Mating behavior and its morphological correlates in two color morphs of Girardinus metallicus (Pisces: Poeciliidae), a species previously thought not to exhibit courtship display.

Girardinus metallicus is a Cuban poeciliid fish whose social behavior has been little studied. The only account involves a colorless morph that is sexually monochromatic and does not exhibit courtship display. We describe the behavior of two other morphs (black and yellow) that exhibit sexual dichromatism.

Body morphology, energy stores, and muscle enzyme activity explain cricket acoustic mate attraction signaling variation.

High mating success in animals is often dependent on males signalling attractively with high effort. Since males should be selected to maximize their reproductive success, female preferences for these traits should result in minimal signal variation persisting in the population. However, extensive signal variation persists.

Preventing the voltage drop: keeping practice-based research network (PBRN) practices engaged in studies.

Introduction: Practice-based research continues to evolve and has become a major methodology for many pragmatic studies. While early practice-based network projects were usually short term, current studies often introduce or compare practice innovations that require long-term evaluation. That change requires that practice sites remain engaged in research work for up to 5 years, a time that can allow for a significant "voltage drop," or decline in active participation.

Communication is the key to success in pragmatic clinical trials in Practice-based Research Networks (PBRNs).

Effective communication is the foundation of feasibility and fidelity in practice-based pragmatic research studies. Doing a study with practices spread over several states requires long-distance communication strategies, including E-mails, faxes, telephone calls, conference calls, and texting. Compared with face-to-face communication, distance communication strategies are less familiar to most study coordinators and research teams.

How age influences phonotaxis in virgin female Jamaican field crickets (Gryllus assimilis).

Female mating preference can be a dominant force shaping the evolution of sexual signals. However, females rarely have consistent mating preferences throughout their lives. Preference flexibility results from complex interactions of predation risk, social and sexual experience, and age.

Adaptive plasticity in wild field cricket's acoustic signaling.

Phenotypic plasticity can be adaptive when phenotypes are closely matched to changes in the environment. In crickets, rhythmic fluctuations in the biotic and abiotic environment regularly result in diel rhythms in density of sexually active individuals. Given that density strongly influences the intensity of sexual selection, we asked whether crickets exhibit plasticity in signaling behavior that aligns with these rhythmic fluctuations in the socio-sexual environment.

Playing to an audience: the social environment influences aggression and victory displays.

Animal behaviour studies have begun to incorporate the influence of the social environment, providing new opportunities for studying signal strategies and evolution. We examined how the presence and sex of an audience influenced aggression and victory display behaviour in field-captured and laboratory-reared field crickets (Gryllus veletis). Audience type, rearing environment and their interaction were important predictors in all model sets.

Protocol for the asthma tools study: a pragmatic practice-based research network trial.

Background: Asthma is common among children, adolescents, and adults. However, management of asthma often fails to follow evidence-based guidelines. Control assessments have been developed, validated against expert opinion, and disseminated.
