A leafhopper is the common name for any species from the family minute insects, colloquially known as hoppers, are plant feeders that suck plant sap from grass, shrubs, or trees. Class: Insecta. Sogawa's study of salivary glands of several leafhopper and planthopper species is one of the few detailed light microscopic descriptions of this group of insects. Although several studies of localization Cited by:

Phenology models predict timing of events in an organism's development. For many organisms which cannot internally regulate their own temperature, development is dependent on temperatures to which they are exposed.
Larva Description: The nymph stage looks like a smaller version of the adult beet leafhopper with under developed wings. Host Plant: Beets, tomato, chile plants.
Ecological Threat. The beet leafhopper causes damage to beets and other crops through the transmission of the Beet. Abstract does not appear. First page follows.
During field investigations were carried on to determine where the beet leafhopper spends the winter and to locate the natural breeding areas in this state. Trips were taken to Death Valley, Mojave Desert, Imperial Valley, and the Tulare Lake and Bakersfieid sections of the San Joaquin Valley—areas from which Ball(2) believed the beet.

In the course of ecological studies of the beet leafhopper (Eutettix tenellus (Bak.)), a large number of population counts vere taken in beet fields within the range of this insect.
The pur-pose of these counts was to determine the time and magnitude of the spring movement from the breeding areas to the beet.
Introduction The beet leafhopper Circulifer ienellus (Baker) is probably the most important species of Cicadellidae in North America. It is the only known vector of the curly top virus disease, which causes great losses to sugar beet, tomato, melon, spinach.

Damage While some damage is caused by nymph and adult feeding, beet leafhopper is a serious pest because it vectors Beet .indicated that there is a large breeding area of the leafhopper in the central Columbia River Valley, in south-central Washington and northeastern Oregon, from which populations are dispersed to the Yakima Valley and other surrounding territory (fig.
