Homopterans including aphids, whiteflies and leafhoppers are the major vectors of viruses
comprising more than 80% of insect-transmitted viruses which represents close to 400 virus …

Plant virus diseases constitute one of the limiting factors to the productivity of agriculture.
Changes in host plants and insect vector populations that might result from climate change (…

This chapter reviews the movement of agriculturally important aphids. It includes information
on how different morphs and life stages redistribute themselves in response to intrinsic …

Transmission of non-persistent plant viruses is related to aphid behaviour during superficial
brief probes. A widely accepted hypothesis postulates that virus acquisition occurs during …

The electrical penetration graph (EPG) technique is a powerful tool for studying feeding
behavior of pierce-sucking insects, because it allows quantification of complex insect–plant …

Detailed information on probing behavior of the Asian citrus psyllid, Diaphorina citri Kuwayama
(Hemiptera: Psyllidae), is critical for understanding the transmission process of phloem‐…

The feeding behavior of the whitefly Bemisia tabaci (Gennadius) was monitored using the
electrical penetration graph (EPG) technique during the transmission process of tomato yellow …

The Gram-negative bacterium Xylella fastidiosa causes disease in a number of important
crops and plants within natural ecosystems. Most notable among these diseases are Pierce's …

Breeding of tomato genotypes that limit whitefly (Bemisia tabaci) access and feeding might
reduce the spread of Tomato yellow leaf curl virus (TYLCV), a begomovirus (genus …

Interactions among the English grain aphid, Macrosiphum (Sitobion) avenae (F.), and three
wheat ( Triticum aestivum L.) cultivars infected with two isolates of barley yellow dwarf virus (…
