Available in PDF, EPUB and Kindle. Book excerpt: The soybean aphid, Aphis glycines Matsumura, arrived first to North America during the midst of 2000. It is a very fast spreading insect and causes a high yield loss of above 50% in most of the soybean growing tracts of United States. Another important economic threat is it's ability to transmit some viruses to soybean. Studies to control this exotic pest started early during the year of its arrival. But a complete integrated pest management (IPM) approach that includes a combination of different control measures has yet to be completely developed. Host plant resistance is one component of integrated pest management and is more sustainable than any other control methods against this insect. In the first study, more than 80 genotypes were screened with two given aphid biotypes, biotype 1 and biotype 2. It was found that the genotypes that were earlier resistant to biotype 1 (K1639, K1642, K1613 K1621, Dowling and Jackson) were susceptible to the new biotype 2 with large populations developing on these genotypes. But we found three new Kansas genotypes that showed resistance only against biotype 1, but not against biotype 2. However, the two of the Michigan genotypes (E06902 and E07906-2) showed resistance to both biotype 1and biotype 2. In second study, the feeding behavior analyses of aphid biotypes were done using the EPG, Electrical penetration graph, technique for a recorded 9 hrs probing time. The resistant and susceptible genotypes show significant differences in their EPG parameters, especially for the sieve element duration in both biotypes. Most of the aphids reached sieve element phase (> 90%) in susceptible genotypes, but only few (

Available in PDF, EPUB and Kindle. Book excerpt: In North America, the soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae) is a pest of soybeans, Glycine max (L.) Merrill. The main goal of this research was to verify the preliminary economic threshold for A. glycines management in Iowa. Secondary goals included; verifying an alternative sampling techniques for estimating A. glycines populations, evaluating the effect of planting date on A. glycines population growth, and investigating the potential of managing both C. trifurcata and A. glycines with a single insecticide program. In 2004-2005, replicated experiments were established at three locations. Results from both years indicate that there is no detectable effect on soybean yield from an insecticide (lambda-cyhalothrin) application made below the current 250 A. glycines per plant economic threshold. Insecticide applications made at 250 A. glycines per plant protected yields when A. glycines populations continued to increase in the control treatment. The insecticide treatment triggered by a binomial sequential sampling (speed scouting) technique resulted in soybean exposure to A. glycines and soybean yield equal to the insecticide treatment applied using an enumerative sampling technique. Insecticide applications triggered by either enumerative sampling or speed scouting resulted in higher yields compared to control treatment when A. glycines populations reached 250 A. glycines per plant. A delay in soybean planting did not result in differences in soybean exposure to A. glycines. However, in both 2004 and 2005 yields in the late planting dates were not protected by insecticide applications. In 2005, foliar insecticides applied based on threshold of 250 A. glycines per plant reduced aphid exposure and protected yield better than preventative insecticide applications (seed treatments). Emphasizing the importance of insecticide timing when managing A. glycines, a foliar formulation of imidacloprid, was applied at threshold of 250 A. glycines per plant reduced A. glycines exposure and had greater yield protection than when imidacloprid was applied as a seed treatment. Experimental evidence from this research supports the current recommendations for soybean aphid management in Iowa (weekly scouting and a foliar insecticide applied when mean populations reach 250 A. glycines per plant on at least 38 plants and are increasing).

Download or read book Pest Management in Soybean written by L.G. Copping and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the third in a series of volumes on major tropical and sub-tropical crops. These books aim to review the current state of the art in management of the total spectrum of pests and diseases which affect these crops in each major growing area using a multi-disciplinary approach. Soybean is economically the most important legume in the world. It is nutritious and easily digested, and is one of the richest and cheapest sources of protein. It is currently vital for the sustenance of many people and it will play an integral role in any future attempts to relieve world hunger. Soybean seed contains about 17% of oil and about 63% of meal, half of which is protein. Modern research has developed a variety of uses for soybean oil. It is processed into margarine, shortening, mayonnaise, salad creams and vegetarian cheeses. Industrially it is used in resins, plastics, paints, adhesives, fertilisers, sizing for cloth, linoleum backing, fire extinguishing materials, printing inks and a variety of other products. Soybean meal is a high-protein meat substitute and is used in the developed countries in many processed foods, including baby foods, but mainly as a feed for livestock. Soybean (Glycine max), which evolved from Glycine ussuriensis, a wild legume native to northern China, has been known and used in China since the eleventh century Be. It was introduced into Europe in the eighteenth century and into the United States in 1804 as an ornamental garden plant in Philadelphia.

Available in PDF, EPUB and Kindle. Book excerpt: The soybean aphid, Aphis glycines Matsumura, is a pest of soybean, Glycine max (L.) Merr. Studies to find control methods were initiated in 2000 when it was first detected in the United States. Aphis glycines can reduce yields by as much as 50%, and vectors several viral diseases. Plant resistance to A. glycines is one important component of integrated control. In the first study, reproduction of A. glycines was compared on 240 soybean entries. Eleven had fewer nymphs produced compared with two susceptible checks (KS4202 and Pioneer[trade mark] 95B15). Antibiosis and antixenosis were assessed in no-choice and choice tests, respectively. Nine entries showed moderate antibiosis and the other two (K1639 and Pioneer[trade mark] 95B97) showed strong antibiosis and antixenosis as categories of resistance to A. glycines. In the second study, chlorophyll loss was estimated in no-choice tests on infested and uninfested leaves of KS4202. The minimum combined number to detect significant chlorophyll loss was 30 aphids confined for 10 days. Using this number, seven resistant entries found in the first study were evaluated. There was no significant chlorophyll reduction between infested and uninfested leaves of five of the resistant entries (K1621, K1639, 95B97, Dowling and Jackson). Jackson and Dowling had a significantly lower percentage loss than the susceptible checks. In the third study, assessment of feeding behavior of A. glycines was compared and recorded for 9 h on four resistant entries and KS4202. The average time needed to reach the first sieve element phase by A. glycines was 3.5 h in KS4202 while in the resistant entries it was 7.5 h, and the total duration in this phase was longer than an hour in KS4202, and only two to seven minutes in the resistant entries. These data suggest that phloem tissues in the resistant plants change feeding behavior. However, aphids first reached the xylem phase and then the sieve element phase, and the time that aphids spent ingesting xylem sap was not different among all entries; therefore, it is possible that xylem sap in the resistant entries may contain toxic substances that alter aphid behavior and restrain further activities on the sieve element phase.
