Feeding studies on the grape leafhopper [PDF]

open access: diamondCalifornia Agriculture, 1965
in areas where natural enemies of the grape leafhopper, Erythroneura elegantula Osb. are absent, or insufficient in numbers, chemical control may be necessary to prevent an increase in leafhoppers from causing serious economic damage.

Surveying: Leafhopper populations [PDF]

open access: diamondCalifornia Agriculture, 1965
Rapid and accurate surveying for grape leafhopper population levels is essential to a decision for necessity of insecticide treatment within an integrated pest control program. These Tulare County studies indicate that counting the nymphs on only two leaves per acre gives as accurate an estimate of the population as did counting the nymphs on fifty ...

Host plant resistance promotes a secondary pest population

open access: yesEcosphere, 2020
Insecticides can cause secondary pest outbreaks that weaken the benefit of chemical pest control. These detrimental nontarget effects motivate the use of alternative pest management strategies such as host plant resistance and intercropping.
