Community Pharmacist-Provided Osteoporosis Screening and Education: Impact on Patient Knowledge

Objective: To evaluate the impact pharmacist-provided screening and education had on patient knowledge of osteoporosis and preventive strategies. Methods: A prospective, randomized, controlled study was conducted at 16 locations of a national supermarket chain pharmacy in the Richmond, Virginia area. Women 30 years and older with no history of osteoporosis were enrolled in the study. Patients self-selected into the study by agreeing to the bone density screening, pharmacist-provided education, and completion of a knowledge survey. Subjects were randomized to complete the osteoporosis-related knowledge survey either before (Group A) or after (Group B) the screening and education session. The survey was developed after guideline and literature evaluation and was pretested with a group of patients for content and clarity. The survey evaluated knowledge of osteoporosis, risk factors for the disease, appropriate age for testing, and preventive strategies. Groups A and B were compared using t-tests. Results: A total of 110 women were enrolled in the study. The mean (±SD) age was 52.5 ± 13.1 years in Group A (n=52) and 52.7 ± 11.5 years in Group B (n=58). Knowledge scores were higher in the group who received pharmacist-provided education prior to completing the survey in each category (knowledge of the disease, risk factors, preventive strategies, and appropriate age for testing) and overall (p<0.001). Conclusions: Community pharmacist-provided osteoporosis screening and education increased patient knowledge about osteoporosis and preventive strategies. Community pharmacist involvement with increasing patient knowledge may empower patients to engage in prevention strategies to improve bone mass.   Type: Original Researc

Combining 1,4-dimethoxybenzene, the major flower volatile of wild strawberry Fragaria vesca, with the aggregation pheromone of the strawberry blossom weevil Anthonomus rubi improves attraction

The aggregation pheromone of strawberry blossom weevil [Anthonomus rubi Herbst (Col.: Curculionidae)], a 1:4:1 blend of Grandlure I, II and racemic lavadulol, has been available for pest monitoring for several years but shows low attractancy. Attempts to control A. rubi using the pheromone alone were also unsuccessful. This paper reports the finding that addition of the major flower volatile from wild strawberry flowers [Fragaria vesca L. (Rosaceae)], 1,4-dimethoxybenzene (comprising 98% of the volatiles emitted from wild strawberry flowers), to the aggregation pheromone increased trap catches by over two fold compared to the pheromone alone. There was no significant difference between the response of overwintered or summer emerged adults. Field trials in 2007-2008 in central and southern Norway, Denmark and southern England used green funnel traps with white cross vanes for the evaluations. (-)-Germacrene D, previously shown to be emitted by plants in increased amounts in the presence of pheromone producing weevils, did not improve trap catches. Thus, the combined use of the aggregation pheromone and 1,4-dimethoxybenzene is promising for improved monitoring and possibly control of this important pest of strawberry

Crop Production, the Pollinator Deficit and Land Use Management: UK Farm Level Survey Results

In this paper, we address a gap in the literature concerning pollination management, the pollinator deficit, and conservation objectives. By employing a farm level survey of UK farmers, we examine farmers’ attitudes, understanding and management of pollinators. Based on descriptive statistics and regression analysis, we found significant variation in interest and understanding of the impact of pollinators on commercial crops meaning that many respondents did not consider they had a pollinator deficit in terms of crop quality, quantity, or financial impacts. At the same time, many farmers are willing to adopt environmentally beneficial land-use measures if suitable advice and financial incentives are offered. However, there is little evidence of coordination of actions between farms to support wild pollinators. These findings indicate a potential disconnect between a farmer’s understanding of the impact on agricultural output from a pollinator deficit and the agricultural benefits from the adoption of specific environmental measures

Busier bees:increasing nest traffic in commercial bumblebee colonies

Commercially-reared bumblebee colonies contribute to the pollination of crops globally. If the efficiency of commercial colonies at providing pollination services could be increased, it would have implications for agricultural outputs. Commercial colonies are sold with an internal nectar reservoir on which bees can forage from within the nest. Nectar stores in naturally-produced nectar pots of colonies can affect forager recruitment and activity outside the nest. Thus, it is possible that artificial nectar reservoirs could impact the foraging activity of colonies. To investigate this, commercial Bombus terrestris audax colonies were placed in a university parkland campus. Colonies were split into three treatment groups: those with (1) access to an unaltered nectar reservoir; (2) access to a diluted reservoir; and (3) no reservoir access. Foraging observations were made for all colonies over a 19-day period. The mass of each colony was measured and demographic data were collected. Colonies with diluted reservoirs had 131% and 39% more bees entering and leaving than colonies with no reservoir access and unaltered reservoirs respectively. Both treatments with access to a nectar reservoir gained more mass, had a higher proportion of pollen foraging bees, and had more workers, males, larvae and pupae, than colonies with no access to a reservoir. These results demonstrate that manipulating the availability and concentration of internal nectar reservoirs of commercial B. terrestris colonies significantly affects the number of bees entering and leaving the colony. Dilution of the nectar reservoir could be a strategy for increasing the pollination services commercial colonies provide to crops. Further research in commercial crops is required before such a strategy could be implemented on farms

The Efficacy of Yeast Phagostimulant Baits in Attract-and-Kill Strategies Varies between Summer- and Winter-Morphs of Drosophila suzukii

Drosophila suzukii (Matsumura), is a globally invasive pest of soft and stone fruit. To survive winter in temperate zones it enters a reproductive diapause in a morphologically distinct phenotype. Phagostimulant baits can be combined with insecticides in attract-and-kill strategies for control. We investigated the effectiveness of single yeast species and combinations of co-fermented yeast phagostimulant baits when combined with insecticides in laboratory assays against both summer- and winter-morph D. suzukii. Candida zemplininia or Hanseniaspora uvarum + C. zemplininia combined with lambda-cyhalothrin or cyantraniliprole, and H. uvarum combined with cyantraniliprole caused significantly higher mortality in winter- compared to summer-morph D. suzukii. Additionally, lambda- cyhalothrin combined with M. pulcherrima + H. uvarum resulted in greater mortality compared to single yeasts, H. uvarum for both summer- and winter-morphs and C. zemplininia for summer- morphs. M. pulcherrima + H. uvarum with spinosad significantly reduced the time-to-kill (50%) of summer-morphs compared to insecticide alone. Most yeast-based baits were comparable in terms of attract-and-kill efficacy to Combi-protec, a commercially available bait, although M. pulcherrima or H. uvarum + C. zemplininia in with cyantraniliprole were less effective. Our study suggests that yeast phagostimulants in attract-and-kill strategies should be adjusted for summer- and winter-morph D. suzukii for more effective control

The use of light spectrum blocking films to reduce populations of Drosophila suzukii Matsumura in fruit crops

Spotted wing drosophila, Drosophila suzukii, is a serious invasive pest impacting the production of multiple fruit crops, including soft and stone fruits such as strawberries, raspberries and cherries. Effective control is challenging and reliant on integrated pest management which includes the use of an ever decreasing number of approved insecticides. New means to reduce the impact of this pest that can be integrated into control strategies are urgently required. In many production regions, including the UK, soft fruit are typically grown inside tunnels clad with polyethylene based materials. These can be modified to filter specific wavebands of light. We investigated whether targeted spectral modifications to cladding materials that disrupt insect vision could reduce the incidence of D. suzukii. We present a novel approach that starts from a neuroscientific investigation of insect sensory systems and ends with infield testing of new cladding materials inspired by the biological data. We show D. suzukii are predominantly sensitive to wavelengths below 405 nm (ultraviolet) and above 565 nm (orange & red) and that targeted blocking of lower wavebands (up to 430 nm) using light restricting materials reduces pest populations up to 73% in field trials

MANAGEMENT OF STRAWBERRY BLOSSOM WEEVIL AND EUROPEAN TARNISHED PLANT BUG IN ORGANIC STRAWBERRY AND RASPBERRY USING SEMIOCHEMICAL TRAPS “Softpest Multitrap”

Many European growers of organic strawberry and raspberry have large losses in yield (sometimes >80%) and reduced quality of their products because of insect damage. Among the major threats are the strawberry blossom weevil (Anthonomus rubi Herbst), the European tarnished plant bug (Lygus rugulipennis Popp.) and the raspberry beetle (Byturus tomentosus De Geer). In organic soft fruit production there are no effective control measures for these pest insects. For many insects species pheromones and host plant volatiles are of major importance in mate finding and location of host plants for mating, feeding and oviposition. Thus, there is potential for using these insect-insect and/or insect-host plant interactions to develop new strategies and effective control measures for pest insects. In this project we want to extend our knowledge of these systems to develop effective control measures to control these pests in organic crops

Trapping of Lygus rugulipennis in Norwegian strawberry crops

European tarnished plant bug (ETB) sex pheromone traps in Norwegian strawberry must be deployed very early in the season to maximize catches. To trap females or the new generation, other attractants must be added. The strawberry blossom weevil attractant PV2 may act as a slight antagonist in ETB trapping, especially early in the season

Traps for Lygus rugulipennis and Anthonomus rubi: preliminary results from Softpest Multitrap activities in Latvia

There is a lack of appropriate plant protection methods against strawberry blossom weevil (SBW) not only in organic plantations, but also in plantations, where IPM is used. European tarnished plant bug (ETPB) is not currently recognized as a pest in Latvian strawberry plantations, because the visual defects made by bugs are not important for Latvian consumers. Cross vane bucket traps and sticky stake traps were the most effective for trapping SBW in Latvia. These traps, where the lure was positioned at the top of cross vanes, were also the most effective for capturing ETPB

Mass trapping Anthonomus rubi and Lygus rugulipennis in strawberries

The strawberry blossom weevil, Anthonomus rubi, and the European tarnished plant bug,Lygus rugulipennis, can cause substantial damage in organic strawberries in Northern and Central Europe. In conventional production it is also desirable to find alternatives to current pesticide controls, which negatively affects beneficials and also creates a risk of building pesticide resistance. Anthonomus rubi lays an egg in a developing flower bud and then partially bites off the flower stem, resulting in a loss of yield. Lygus rugulipennis nymphs and adults feed on flowers and developing fruitlets, causing a fruit distortion which makes the damaged fruit unmarketable. In the ERA-NET CORE Organic project “Softpest Multitrap”, we studied how pheromone and plant volatiles can be combined to improve trapping of the two pests. Our studies also included trap design and placement of traps in the field (grid size, perimeter versus field centre), investigations of the phenology of A. rubi and L. rugulipennis. In 2014 we assessed a ‘multi’-trap for both species. Results will be presented and discussed
