| can leek interfere with bean plant-bean fly interaction? test of ecological pest management in mixed cropping. | effects of volatile odors from leek, allium porum l., on the behavior of bean fly, ophiomyia phaseoli (tryon) (diptera: agromyzidae), were tested in laboratory olfactometer bioassays. aqueous and solvent extracts (dichloromethane and methanol) of leek were repellent to adult flies. whole leek plants were repellent and prevented attraction to the host plant, beans. beans that had been exposed to volatiles from living leek plants for 7 d became repellent to the fly. leek and several other crops we ... | 2009 | 19610413 |
| phaseolus immature embryo rescue technology. | predominant among the production constraints of the common bean phaseolus vulgaris are infestation of ascochyta blight, bean golden mosaic virus (bgmv), and bean fly. interbreeding with phaseolus -coccineus l. and/or phaseolus polyanthus greenm has been shown to provide p. vulgaris with greater resistance to these diseases. for interspecific crosses to be successful, it is important to use p. coccineus and p. polyanthus as female parents; this prevents rapid reversal to the recurrent parent p. v ... | 2011 | 21207266 |
| the use of common bean (phaseolus vulgaris) traditional varieties and their mixtures with commercial varieties to manage bean fly (ophiomyia spp.) infestations in uganda. | the bean fly (ophiomyia spp.) is considered the most economically damaging field insect pest of common beans in uganda. despite the use of existing pest management approaches, reported damage has remained high. forty-eight traditional and improved common bean varieties currently grown in farmers' fields were evaluated for resistance against bean fly. data on bean fly incidence, severity and root damage from bean stem maggot were collected. generalized linear mixed model (glmm) revealed significa ... | 2017 | 26924956 |
