Irrigated almond orchards in Spain are increasing acreage, and it is pertinent to study the effect of deficit irrigation on presence pests, plant damage, other arthropod communities. In an orchard examined from 2017 2020, arthropods diseases were studied by visual sampling under two treatments (T1, control T2, regulated (RDI)). Univariate analysis showed no influence aphid Hyalopterus amygdali ...

The effect of irrigation on the abundance of Empoasca vitis (Göthe) populations was investigated in four vineyards located in northeastern Italy. In two experiments, we compared leafhopper population densities in plots irrigated (micro-spray irrigation system) or nonirrigated. In another experiment, we studied the effect of various irrigation systems on E. vitis populations over two successive ...

Systemic insecticides and application methods were evaluated in two trials that began in 2005 and 2006 for control of potato leafhopper (Empoasca fabae [Harris]) on four red maple (Acer rubrum L.) cultivars and rated annually through 2007. Treatments evaluated in this study included surface drenches of imidacloprid plus cyfl uthrin (Discus) or imidacloprid plus bifenthrin (Allectus SC), clothia...
