The Development of a Sex Pheromone Lure for the American Plum Borer, \u3ci\u3eEuzophera Semifuneralis\u3c/i\u3e (Lepidoptera: Pyralidae), a Major Pest of Cherry in Michigan.

Pheromone components of the American plum borer, Euzophera semifuneralis, were defined by use of the electroantennogram screening technique and capillary gas chromatographic retention times of sex pheromone gland constituents. Field studies showed that greatest attraction was achieved with a 1 mg load rate of a 4-component blend in a rubber septum. This blend consisted of a 2:1 ratio of Z,E-9,12-14:ALD and Z9-14:ALD and an equal amount of the corresponding alcohols in a 2:1 ratio, respectively. Commercial lures were used to compare the flight patterns of the American plum borer, peachtree borer (Synanthedon exitiosa), and lesser peachtree borer (Synanthedon pictipes) adults in Michigan in 1988

Natural Enemies of Cranberry Fruitworm, \u3ci\u3eAcrobasis Vaccinii\u3c/i\u3e, (Lepidoptera: Pyraudae) in Michigan Highbush Blueberries

A two-year study was conducted in Michigan highbush blueberries to determine the complex of parasitoids attacking cranberry fruitworm, Acrobasis vaccinii. Eight parasitoid species and one fungal pathogen were collected. Parasitism of collected hosts ranged from 6.6% to 28.1%. The more common larval parasitoid encountered was Campoletis patsuiketorum (Hymenoptera: Ichneumonidae). The more common parasitoid recovered from fruitworm hibernacula was Villa lateralis (Diptera: Bombyliidae). This study documented six unreported natural enemies of cranberry fruitworm, including C. patsuiketorum; V. lateralis; Diadegma compressum (Hymenoptera: Ichneumonidae); Compsilura concinnata (Diptera: Tachinidae); Memorilla pyste (Diptera: Tachinidae); an undescribed Microtypus species (Hymenoptera: Braconidae); and a fungal pathogen, Paecilomyces near farinosus. This is the first known host association for the undescribed Microtypus species, and increases the known parasitoid complex of cranberry fruitworm to 17 species

MODELING EXTENSIVE LIVESTOCK PRODUCTION SYSTEMS: AN APPLICATION TO SHEEP PRODUCTION IN KAZAKHSTAN

A stochastic dynamic programming model for extensive livestock systems is developed. The model optimizes sales/retention decisions when future forage production, which affects animal performance and hence profitability, is uncertain. The model is applied to sheep production in Kazakhstan to evaluate policy alternatives.Livestock Production/Industries,

A call for high quality early childhood education in the early years of school in Western Australia

This paper has been written in response to the growing concerns from educators of children in the early years of school (kindergarten to year 2) and university teacher educators who are experiencing first-hand a rapid increase in the formalisation of the early years of schooling in many classrooms in Western Australia (The West Australian, 2013). Concerns for the general and long term health and wellbeing of young children have surfaced in the early childhood profession as we witness increased pressure placed on improving school achievement in national literacy and numeracy tests (King & Janson, 2009; Wescombe-Down, 2013)

A call for a WA Play Strategy in Early Childhood Education and Care

In 2013, ECA WA members were invited to contribute to the development of a strategic plan that would set priorities, focus energy and resources, and work toward the core function of Early Childhood Australia: to advocate for the rights and well-being of children in early childhood education and care (ECEC). Members identified the diminishing opportunities for children (aged birth to eight years) to access quality play in these environments as a major concern necessitating it as a key priority in future planning. The vision that child-initiated and self-directed play be reinstated as a fundamental right in early education and care settings, including the early years of schooling, was similarly shared by members of other leading early childhood advocacy organisations in WA (OMEP, ECTA, EYES and the SSTUWA). Moreover, the demise of play in ECEC was considered by key stakeholder representatives (of Playgroup WA, CareWest, Family Day Care WA, Meerilinga, and Childcare Association of WA) at the ECA WA AGM (2014) during a Panel Discussion on Play. Shortly thereafter, ECA WA pledged its commitment to developing a play strategy initiative
