Physical Control of Leafhoppers
Journal of Economic Entomology, 2008In 2000, a severe outbreak of phytoplasma-caused disease in Limonium spp. flowers devastated the industry in Israel; insecticides were not able to knock down and kill leafhopper vectors before they could transmit the pathogen. Nonchoice laboratory studies were conducted to determine the effect of UV-absorbing plastics on the movement of leafhoppers ...

Potato Leafhopper Control, 1987
Insecticide and Acaricide Tests, 1988Abstract This test was conducted at the Delaware State College Farm in Dover on a 2-year stand of ‘Saranac AR’ alfalfa. Plots were 16 × 20 ft arranged in a randomized complete block design replicated 4 times. In Experiment 1, treatments were applied with a bicycle design, C02-pressurized sprayer delivering 30 gal/acre at 40 psi on 6-inch-

BACKGROUND Empoasca onukii, the tea green leafhopper, is a key pest of tea whose control often requires the extensive use of insecticides. As a predator of the tea green leafhopper, the mite Anystis baccarum is a potential biological control agent ...

Insecticide and Acaricide Tests, 1990
Abstract Insecticides were applied to 7-yr-old trees in Douglas, MI on 11 Jul at a rate of 300 gal/acre with an FMC 1029 handgun sprayer. Treatments were arranged in a completely randomized design of single trees replicated 4 times. Difolitan, Captec, Bayleton, and Baycor were applied separately to all treatments.

Insecticide and Acaricide Tests, 1989
Abstract ‘PMR 45’ cantaloupes, planted 12 May at the Arkansas Valley Research Center, Rocky Ford, Colo., were used in the study. Plots were 2 beds (60-inch spacing), 24 ft long, arranged in a randomized complete block design with 4 replications.

Screening of a potential leafhopper attractants and their applications in tea plantations
Journal of Environmental Science and Health. Part B - Pesticides, Food Contaminants, and Agricultural Wastes, 2019Pheromones can be used as leafhopper attractants. However, commercial pheromone products, such as the Ingle lure, have certain limitations, including poor persistence in the field. In this study, (E)-2-hexenal, (Z)-3-hexen-1-ol, (Z)-3-hexenyl acetate, (E)

Annals of the Entomological Society of America, 1926
The members of the family Cicadellidae are commonly regarded as herbivorous since they are thought to depend entirely on plant juices for their food. It has been known for some time, however, that they will bite man. Riley and Johannsen, for example, mention Platymetopius acutus (Say) and Empoasca mali (LeB.) in this connection.

Potato Leafhopper Control, 1981
Insecticide and Acaricide Tests, 1982Abstract The test was planted Jun 15 on the Cal Waterman farm near Batavia, NY. Each treatment consisted of two 30-ft rows bordered on each side by 2 untreated rows replicated 4 times in a Latin square design. Sidedress applications (2 inches to the side and 2 inches deep) using a hand-pushed cone seeder were made on Jun 29 (primary leaf
