PHYSIOLOGICAL ECOLOGY Seasonal Timing of Diapause Induction Limits the Effective Range of Diorhabda elongata deserticola (Coleoptera: Chrysomelidae) as a Biological Control Agent for Tamarisk (Tamarix spp.)
The leaf beetle Diorhabda elongata Brullé subspecies deserticola Chen, collected in northwestern China, has been released in the western United States to control tamarisk (Tamarix spp.). While beetle establishment and saltcedar defoliation have been noted at northern study sites, this species has not established at latitudes south of the 38th parallel. Critical daylength for diapause induction ...
متن کاملMeasuring Transpiration of Undisturbed Tamarisk Shrubs.
Scarcity of water suitable for human use has influenced the history of mankind profoundly (4) and is now of major concern in the United States. It is of acute local concern in Phoenix, Ariz. and desert environs, where a rapidly increasing human population depends on one remote watershed (Salt River) for its primary water supply (2). Here, problems of watershed management are not of mere scholar...
متن کاملRemote Sensing and Mapping of Tamarisk along the Colorado River, USA: A Comparative Use of Summer-Acquired Hyperion, Thematic Mapper and QuickBird Data
Tamarisk (Tamarix spp., saltcedar) is a well-known invasive phreatophyte introduced from Asia to North America in the 1800s. This report compares the efficacy of Landsat 5 Thematic Mapper (TM5), QuickBird (QB) and EO-1 Hyperion data in discriminating tamarisk populations near De Beque, Colorado, USA. As a result of highly correlated reflectance among the spectral bands provided by each sensor, ...
متن کاملField assessment of the risk posed by Diorhabda elongata, a biocontrol agent for control of saltcedar (Tamarix spp.), to a nontarget plant, Frankenia salina
The biological control program for saltcedar (Tamarix spp.) has led to open releases of a specialist beetle (Chrysomelidae: Diorhabda elongata) in several research locations, but the controversy over potential impacts to native, nontarget plants of the genus Frankenia remains unresolved. To assess the potential for nontarget impacts under Weld conditions, we installed cultivated Frankenia spp. ...

The cottonwood leaf beetle, Chrysomela scripta F., is a serious defoliator of plantation Populus in the United States. Current control methods include biorational and synthetic chemicals as well as selecting Populus clones resistant or tolerant to C. scripta defoliation. SpeciÞc ratios of long-chain fatty alcohols to alpha-tocopherylquinone ( -TQ) on the leaf surface of Populus spp. act as phag...
