“…In mature leaves, the leaf edges begin to roll inward, enclosing the aphids in a tubular and protective structure as the RWA colony develops. Rolled leaves shelter the aphids from chemical and biological control methods (Smith et al 1992). The prevention of proper unfolding of new leaves and reduction in leaf size caused by D. noxia feeding apparently results from the reduction of leaf turgor below the threshold for elongation and cell wall extensibility.…”

“…In the United States alone, the economic impact of Russian wheat aphid (RWA) has been estimated at approximately $800 million from 1987 Á1993 (Morrison & Peairs 1998). RWA is a greenish to gray-green phloem-feeding pest of wheat and barley causing devastation in many countries of the world (Smith et al 1992). The first sightings of the RWA in the USA were reported in the spring of 1986 having been introduced via the Texas Panhandle.…”

“…Diuraphis noxia collected from around the world show biotypic differences (Smith et al 1992). Russian wheat aphid populations from Hungary, Russia and Syria have been identified as virulent to the Dn4 resistance gene (Puterka et al 1992, Basky 2002, while populations from Chile, Ethiopia and the Czech Republic also showed virulence to this gene (Smith et al 2004).…”

A lack of understanding the interaction between the Russian wheat aphid (RWA) and its host plant is a limitation in developing effective strategies for controlling the aphid. It is generally assumed that the interaction between aphid and plant is similar to that between plant and pathogen; that is, an elicitor from the insect is recognized by a protein from the host plant and a cascade of signal transduction events follows. However, evidence suggests that RWA feeding is eliciting both the SA-and JA/ethylene-dependent signaling pathways by mimicking aspects of both pathogen and herbivorous insect attacks. Results further suggest that phenotypic symptoms after RWA feeding are under regulation via two independent reactions, namely an immediate response (i.e., leaf rolling) and a downstream event (i.e., chlorosis). These defense responses enable a resistant host plant to defend itself and overcome the stress response, while their susceptible counterparts die. The processes involved in the onset of the defense response are discussed, and mechanisms enabling resistant plants to overcome the stress associated with the feeding process are presented as a working model for RWA-cereal host interaction. Knowledge of genes involved in wheat's defense responses against the RWA and an understanding of their functions may provide additional strategies for developing broad-spectrum resistance in plants.

Choice tests were conducted to determine feeding preferences of European corn borer,Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), neonates for 15 species of plants. Percentage of neonates accepting (found on) each leaf disc after 24 h was measured using choice tests. Initially, nine species of plants were evaluated. The following year, 10 plant species were evaluated during O. nubilalis first generation and 11 species during the second generation. Pennsylvania smartweed, Polygonum pennsylvanicum (L.), had the highest percentage of neonates accepting leaf discs in both years. Other plants with high acceptance rates included swamp smartweed, Polygonum amphibium L.; velvetleaf, Abutilon theophrasti Medicus; cocklebur, Xanthium strumarium L.; and yellow foxtail, Setaria glauca (L.). Corn, Zea mays L., consistently had low percentages of neonates accepting leaf discs along with common waterhemp, Amaranthus rudis Sauer. Implications these results may have on O. nubilalis host plant selection in central Iowa's corn dominated landscape are considered.

Aphids damage major world food and fiber crops through direct feeding and transmission of plant viruses. Fortunately, the development of many aphid-resistant crop plants has provided both ecological and economic benefits to food production. Plant characters governing aphid host selection often dictate eventual plant resistance or susceptibility to aphid herbivory, and these phenotypic characters have been successfully used to map aphid resistance genes. Aphid resistance is often inherited as a dominant trait, but is also polygenic and inherited as recessive or incompletely dominant traits. Most aphid-resistant cultivars exhibit constitutively expressed defenses, but some cultivars exhibit dramatic aphid-induced responses, resulting in the overexpression of large ensembles of putative aphid resistance genes. Two aphid resistance genes have been cloned. Mi-1.2, an NBS-LRR gene from wild tomato, confers resistance to potato aphid and three Meloidogyne root-knot nematode species, and Vat, an NBS-LRR gene from melon, controls resistance to the cotton/melon aphid and to some viruses. Virulence to aphid resistance genes of plants occurs in 17 aphid species--more than half of all arthropod biotypes demonstrating virulence. The continual appearance of aphid virulence underscores the need to identify new sources of resistance of diverse sequence and function in order to delay or prevent biotype development.
