large-scale field application of rnai technology reducing israeli acute paralysis virus disease in honey bees (apis mellifera, hymenoptera: apidae). | the importance of honey bees to the world economy far surpasses their contribution in terms of honey production; they are responsible for up to 30% of the world's food production through pollination of crops. since fall 2006, honey bees in the u.s. have faced a serious population decline, due in part to a phenomenon called colony collapse disorder (ccd), which is a disease syndrome that is likely caused by several factors. data from an initial study in which investigators compared pathogens in h ... | 2010 | 21203478 |
hygienic and grooming behaviors in african and european honeybees-new damage categories in varroa destructor. | varroa destructor is an ectoparasitic pest of honeybees, and a threat to the survival of the apiculture industry. several studies have shown that unlike european honeybees, african honeybee populations appear to be minimally affected when attacked by this mite. however, little is known about the underlying drivers contributing to survival of african honeybee populations against the mite. we hypothesized that resistant behavioral defenses are responsible for the survival of african honeybees agai ... | 2017 | 28622341 |
formic acid treatment for control of varroa destructor (mesostigmata: varroidae) and safety to apis mellifera (hymenoptera: apidae) under southern united states conditions. | the efficacy of a formic acid pad formulation was field tested for control of the honey bee parasitic mite varroa destructor anderson & trueman in florida and texas. this pad formulation gave 39.8 +/- 11.1% control at the end of a 6-wk treatment period, which did not significantly differ from the initial sample date. coumaphos treatment provided poor control (38.4 +/- 11.1%) over the 6-wk period, confirming reports of coumaphos resistance in the region. under relatively warm winter conditions in ... | 2004 | 15568336 |
pollinator-mediated competition between two co-flowering neotropical mangrove species, avicennia germinans (avicenniaceae) and laguncularia racemosa (combretaceae). | three ecological relationships are possible between co-flowering plant species; they may have no effect on one another, compete for pollination services, or facilitate one another by attracting more pollinators to the area. in this study, the pollinator-mediated relationship between two mangrove species with overlapping flowering phenologies was investigated in one south florida community. | 2013 | 23235696 |
an evaluation of the honey bee (hymenoptera: apidae) safety profile of a new systemic insecticide, flupyradifurone, under field conditions in florida. | flupyradifurone (sivanto) is a novel systemic insecticide from the butenolide class developed by bayer. based on available data (usepa 2014), this insecticide appears to have a favorable safety profile for honey bee colonies. as a result, the label permits the product to be applied during prebloom and bloom in various crops, including citrus, except when mixed with azole fungicides during the blooming period. we placed 24 honey bee (apis mellifera l.) colonies adjacent to eight flowering buckwhe ... | 2016 | 27563069 |
managed bumble bees (bombus impatiens) (hymenoptera: apidae) caged with blueberry bushes at high density did not increase fruit set or fruit weight compared to open pollination. | highbush blueberry (vaccinium corymbosum l.) is an important crop grown throughout florida. currently, most blueberry growers use honey bees (apis mellifera l.) to provide pollination services for highbush blueberries even though bumble bees (bombus spp.) have been shown to be more efficient at pollinating blueberries on a per bee basis. in general, contribution of bumble bees to the pollination of commercial highbush blueberries in florida is unknown. herein, we determined if managed bumble bee ... | 2017 | 28334127 |
efficacy of strips coated with metarhizium anisopliae for control of varroa destructor (acari: varroidae) in honey bee colonies in texas and florida. | strips coated with conidia of metarhizium anisopliae (metschinkoff; deuteromycetes: hyphomycetes) to control the parasitic mite, varroa destructor (anderson and trueman) in colonies of honey bees, apis mellifera (hymenoptera: apidae) were compared against the miticide, tau-fluvalinate (apistan) in field trials in texas and florida (usa). apistan and the fungal treatments resulted in successful control of mite populations in both locations. at the end of the 42-day period of the experiment in tex ... | 2007 | 17203363 |
