The soybean aphid (Aphis glycines Matsumura) is an insect pest of soybean (Glycine max (L.) Merr.) that is exotic to North America.
The soybean aphid is native to Asia. It has been described as a common pest of soybeans in China and as an occasional pest of soybeans in Indonesia, Japan, Korea, Malaysia, the Philippines, and Thailand. The soybean aphid was first Family: Aphididae. CHAPTER 8 ACCESSORY FACTORS IN NONPERSISTENT VIRUS TRANSMISSION Thomas P.

Most plant viruses are rod-shaped, with protein discs forming a tube surrounding the viral genome; isometric particles are another common structure. contained substances inhibitory to the transmission of tobacco mosaic virus.

H., and H. Miller. Philodendron. Some insects and mites, including many kinds of aphids, are highly dedicated to just one or a few types of host plants and will not establish populations in crop plants nearby.
For example, banker plants such as barley or oats, can be used to maintain grain aphids that are an alternate food source for beneficial insects, such as ladybeetles or.
Effects were smaller after April: earlier sowing increased total dry weight by 25–30 t/ha and, when leaf diseases and barley yellow dwarf virus were controlled, increased yield by 09-l0t/ha.
Increasing the amount of N applied by 70 kg/ha (from or 80), increased yield only in and then only when fungicide was by: Persistent circulative transmission of plant viruses involves complex interactions between the transmitted virus and its insect vector.
Several studies have shown that insect vector proteins are involved in the passage and the transmission of the virus. Interestingly, proteins expressed by bacterial endosymbionts that reside in the insect vector, were also shown to influence the Cited by: Examples of viruses spread by soybean aphid include alfalfa mosaic virus, soybean mosaic virus, and bean yellow mosaic virus.

Distroy crop residue in the fall to help manage some. Fungicide temporarily decreased the incidence of some components of the mioroflora on the ears. Pesticide increased grain yield of wheat after oats only inwhen aphids on the ears were numerous. Aphids were present on early-sown plots in all three autumns but there was little barley yellow dwarf virus infection even without by: It is a recombinant with a major parent (nts98% ID; 84% of the sequence) closest to an unusual isolate of sugarcane mosaic virus from Canna sp., in China (KY), and a minor parent (nts ) closest to an unusual isolate of bean yellow mosaic virus (DQ; 95% ID) also isolated from “naturally planted” Canna sp., in Author: Adrian J.

The motley virus disease of carrots has been reported by Stubbs () to be be transmitted by aphids or by leafhoppers, but some of them are now known to be.
Figure Ryegrass mosaic virus on annual ryegrass (severe strain). Ryegrass mosaic virus (RMV) causes a light green to yellow mosaic on Lolium spp. and has been reported from North America and Europe (Slykhuis, ). In Great Britain, RMV is probably the most damaging disease of annual and perennial ryegrasses (Heard et al., ).
INTRODUCTION. Over the past twenty five years, Arabidopsis thaliana has been utilized as a model plant to study plant growth, development and adaptation to the environment (Koornneef and Meinke, ).Arabidopsis has also provided valuable information on plant-insect interactions, including those involving insects in the orders Coleoptera, Diptera, Hemiptera, Cited by: Abstract.
Virus and viroid diseases are serious constraints to the production and profitability of a wide range of tropical crops. Many plant virus outbreaks have been recorded in the last two decades around the world and the ultimate aim of the applied plant virologist is to devise measures for combating the virus and viroid by:.

This revision and update of the well-received first edition published ten years ago reflects the expansion of research in genomics, endosymbionts and semiochemicals, as well as the shift from control of aphids with.
Aphids are important pests of plants that use their stylets to tap into the sieve elements to consume phloem sap. Besides the removal of photosynthates, aphid infestation also alters source-sink patterns. Most aphids also vector viral diseases. In this chapter, we will summarize on recent significant findings in plant-aphid interaction, and how studies involving Cited by:
