| ecological studies of adult ixodes scapularis in central mississippi: questing activity in relation to time of year, vegetation type, and meteorologic conditions. | adult ixodes scapularis say were collected weekly during two fall-winter-spring seasons from 1989 to 1991 to assess their temporal and spatial distribution as well as the effects of several meteorologic parameters on questing activity. collections were made in three 0.4-ha sites in central mississippi by flagging vegetation with a white flannel cloth. adult i. scapularis were collected from 25 october through 11 april during the 1989-1990 season and 24 october-1 april in the 1990-1991 season. pe ... | 1992 | 1625300 |
| host specificity of argopistes tsekooni (coleoptera: chrysomelidae), a potential biological control agent of chinese privet. | chinese privet, ligustrum sinense lour., is a perennial semi-evergreen shrub that is a serious invasive weed in the united states. classical biological control offers the best hope for controlling it in an economic, effective, and persistent way. host specificity of one of the most promising biological control agents of chinese privet, a flea beetle, argopistes tsekooni chen (coleoptera: chrysomelidae), was evaluated in china by using laboratory no-choice and choice tests on 13 species of oleace ... | 2008 | 18767722 |
| parasitism of woody ornamentals by meloidogyne hapla. | meloidogyne hapla is the dominant root-knot nematode found in tennessee woody ornamental nurseries. in greenhouse tests, m. hapla produced galls and formed egg masses on roots of abelia x grandiflora, comus florida, hydrangea paniculata grandiflora, photinia x fraseri, spiraea x bumalda, spiraea x vanhouttei, and viburnum carlesii. galls on h. grandiflora and v. carlesii were mostly large and fusiform. galls on c. florida were spherical and usually terminal, whereas those on the other species we ... | 1987 | 19290273 |
| combined treatment of pseudomonas aeruginosa pa01 biofilm formation with the water-soluble extract of ligustrum sinense and gentamicin sulphate. | ligustrum sinense are commonly used for their anti-inflammatory, anti-rheumatic, diuretic, and hypotensive activities in traditional chinese medicine. to observe the effects of the combined treatment of a water-soluble extract of ligustrum sinense (wel) and gentamicin sulphate (gs) on pseudomonas aeruginosa pa01, the micro-dilution method was used to determine the minimal inhibitory concentration (mic) of gs. formation of a pa01 biofilm was observed under an optical microscope after treatment wi ... | 2013 | 24620617 |
| co-occurring nonnative woody shrubs have additive and non-additive soil legacies. | to maximize limited conservation funds and prioritize management projects that are likely to succeed, accurate assessment of invasive nonnative species impacts is essential. a common challenge to prioritization is a limited knowledge of the difference between the impacts of a single nonnative species compared to the impacts of nonnative species when they co-occur, and in particular predicting when impacts of co-occurring nonnative species will be non-additive. understanding non-additivity is imp ... | 2016 | 27755688 |
| fundamental host range of leptoypha hospita (hemiptera: tingidae), a potential biological control agent of chinese privet. | chinese privet, ligustrum sinense lour., is an invasive shrub within riparian areas of the southeastern united states. biological control is considered the most suitable management option for chinese privet. the potential host range of the lace bug, leptoypha hospita drake et poor, was evaluated on the basis of adult feeding and oviposition, combined oviposition-nymphal development no-choice tests, nymphal development no-choice tests, multiple generation comparison on forestiera pubescens nutt. ... | 2016 | 27325627 |
