Reduction of noncrop habitats, intensive use of pesticides and high levels of disturbance associated with intensive crop production simplify the farming landscape and bring about a sharp decline of biodiversity. This, in turn, weakens the biological control ecosystem service provided by arthropod natural enemies. Strategic use of flowering plants to enhance plant biodiversity in a well-targeted manner can provide natural enemies with food sources and shelter to improve biological control and reduce dependence on chemical pesticides. This article reviews the nutritional value of various types of plant-derived food for natural enemies, possible adverse effects on pest management, and the practical application of flowering plants in orchards, vegetables and field crops, agricultural systems where most research has taken place. Prospects for more effective use of flowering plants to maximize biological control of insect pests in agroecosystem are good but depend up on selection of optimal plant species based on information on the ecological mechanisms by which natural enemies are selectively favored over pest species.

The brown planthopper (BPH) Nilaparvata lugens, whitebacked planthopper (WBPH) Sogatella furcifera and smaller BPH Laodelphax striatellus increasingly exhibit resistance to insecticides and adaptation to resistant varieties, so they threaten food security. This review draws together, for the first time, information on the parasitoids of planthopper pests of rice from the non-English literature published in Asia. This is integrated with the English language literature to provide a comprehensive analysis. Planthopper pests of rice are attacked by a large range of parasitoids from Strepsiptera, Diptera and, especially, Hymenoptera. Levels of field parasitism vary widely between parasitoid species and locations. For many taxa, especially within Mymaridae, there is evidence that non-crop habitats are important as overwintering habitat in which alternative hosts are available. These source habitats may promote early season parasitism of pest Hemiptera in rice crops, and their movement into crops could be manipulated with applications of herbivoreinduced plant volatiles. Non-crop plants can also provide nectar to improve parasitoid longevity and fecundity. Despite evidence for the importance of environmental factors affecting parasitoids of rice pests, the use of habitat manipulation to enhance biological control in the world's most important crop is surprisingly underrepresented in the literature. Current research in China, Vietnam and Thailand on ecological engineering, carefully selected vegetation diversity introduced without disrupting profitable farming, is briefly reported. Although the most important pest, BPH (N. lugens), is a migratory species, maintaining local communities of parasitoids and other natural enemies offers scope to prevent even r-selected pests from reaching damaging population densities.

Young Aboriginal fathers face social and emotional challenges in the transition to fatherhood, yet culturally appropriate support mechanisms are lacking. Peer mentoring to develop online- and mobile phone-based resources and support may be a viable approach to successfully engage these young men. This feasibility study engaged two trusted Aboriginal mentors and researchers to partner with one regional and two rural Aboriginal communities in New South Wales, Australia. Early in the research process, 20 young Aboriginal fathers were recruited as co-investigators. These fathers were integral in the development of web-based resources and testing of mobile phone-based text messaging and mood-tracking programs tailored to provide fathering and mental health support. Overwhelmingly positive feedback from evaluations reinforced community pride in and ownership of the outcomes. The young men's involvement was instrumental in not only developing culturally appropriate support, but also in building their capacity as role models for other fathers in the community. The positive results from this feasibility study support the adoption of participatory approaches in the development of resources for Aboriginal communities.

Objective: This evaluation considered the potential of We-Yarn, a suicide prevention gatekeeper training workshop, to contribute to Aboriginal suicide prevention in rural New South Wales. Design: A mixed methods approach included surveys, in-depth interviews and workshop observations. Setting: Aboriginal suicide prevention training in rural New South Wales, Australia.

Background Suicide rates are higher in rural Australia than in major cities, although the factors contributing to this are not well understood. This study highlights trends in suicide and examines the prevalence of mental health problems and service utilisation of non-Indigenous Australians by geographic remoteness in rural Australia. Methods A retrospective study of National Coronial Information System data of intentional self-harm deaths in rural New South Wales, Queensland, South Australia and Tasmania for 2010–2015 from the National Coronial Information System. Results There were 3163 closed cases of intentional self-harm deaths by non-Indigenous Australians for the period 2010–2015. The suicide rate of 12.7 deaths per 100,000 persons was 11% higher than the national Australian rate and increased with remoteness. Among people who died by suicide, up to 56% had a diagnosed mental illness, and a further 24% had undiagnosed symptoms. Reported diagnoses of mental illness decreased with remoteness, as did treatment for mental illness, particularly in men. The most reported diagnoses were mood disorders (70%), psychotic disorders (9%) and anxiety disorders (8%). In the six weeks before suicide, 22% of cases had visited any type of health service at least once, and 6% had visited two or more services. Medication alone accounted for 76% of all cases treated. Conclusions Higher suicide rates in rural areas, which increase with remoteness, may be attributable to decreasing diagnosis and treatment of mental disorders, particularly in men. Less availability of mental health specialists coupled with socio-demographic factors within more remote areas may contribute to lower mental health diagnoses and treatment. Despite an emphasis on improving health-seeking and service accessibility in rural Australia, research is needed to determine factors related to the under-utilisation of services and treatment by specific groups vulnerable to death by suicide.

On the basis of reports demonstrating possible roles for leukocyte function-associated antigen 1 (LFA-1) and intercellular adhesion molecule 1 (ICAM-1), the ligand for LFA-1, in human immunodeficiency virus type 1 (HIV-1) infection, we have explored the involvement of the ICAM-1 molecule by using selected synthetic peptides derived from the protein sequence. Replication was assessed in MT-2 cells, highly susceptible to HIV infection, in the presence of four synthetic peptides derived from the ICAM-1 amino acid sequence. This cell type was chosen for the ability to form marked syncytia on infection with cell-free virus. Under the conditions used, minimal or no cytotoxicity was observed with the peptides up to concentrations of 50 micrograms/ml. A peptide corresponding to a unique region of ICAM-1, JF9 [ICAM-1(367-394, A-378)], had little effect on virus replication despite its ability to inhibit cell-cell adhesion. In contrast, an N-terminal peptide, JF7B [ICAM-1(1-23)], consistently inhibited virus replication in MT-2 cells in a dose-dependent manner, as measured by cell-free reverse transcriptase (RT) activity (up to 70% inhibition), soluble virus antigen production (up to 60% inhibition), and syncytium formation (virtually complete inhibition up to 6 days post infection). Testing of W-CAM-1 antibody, and anti-ICAM-1 antibody that inhibits cell-cell adhesion, revealed no significant inhibitory effects on RT activity, virus antigen production, and syncytium formation in HIV-1-infected MT-2 cells at a level that markedly inhibited cell-cell adhesion (10 micrograms/ml).(ABSTRACT TRUNCATED AT 250 WORDS)

Introduction: Integrated care has been posited as an important strategy for overcoming service fragmentation problems and achieving the Quadruple Aim of health care. This paper describes the Central Coast Integrative Care Program (CCICP) a complex, multi-component intervention addressing 3 target populations and more than 40 sub-projects of different scale, priority and maturity. Details are provided of the implementation including activities undertaken for each target population, in the context of the Central Coast Local Health District (CCLHD) strategies and priorities. Key lessons are drawn from the formative evaluation. Methods: A mixed methods approach to the formative evaluation was taken. Key stakeholders, professional staff with an in-depth knowledge of the program, were invited to complete surveys (n = 27) and semi-structured interviews (n = 23). The evaluation employed co-design principles with dialogue between CCICP partners and researchers throughout the process and sought to achieve a shared understanding of the dynamic context of the program, and the barriers and enablers for the various interventions. Key lessons and conclusion: Seven interdependent key lessons have been identified. These distil down to the setting of clear objectives aligning with all the goals of partners, developing strong relationships, leadership at multiple levels and communication and the building of a common language.
