• pest
  • The soybean aphid is the only soybean insect pest known to have multiple biotypes, said Glen Hartman, U of I professor of crop sciences and USDA research plant pathologist. (innovations-report.com)
  • The discovery of an aphid biotype that can overcome the gene means breeders and seed companies will need to keep pace with the pest. (innovations-report.com)
  • biotype B (Hemiptera: Aleyrodidae) is an important pest of vegetable crops, including collard greens Brassica oleracea var. (deepdyve.com)
  • A pest is any species, strain or biotype of plant, animal, or pathogenic agent injurious to plants or plant products. (wikipedia.org)
  • The sugarcane aphid has become a severe pest of North American sorghum production over the last few years. (yumpu.com)
  • Sugarcane aphids were first documented in the United States in 1977 but did not become a pest of sorghum until 2013, after which they spread rapidly across sorghum-producing areas of the U.S. and Mexico. (yumpu.com)
  • Sugarcane aphid has long been a pest of sugarcane and sorghum outside of North America, including parts of Africa, Asia, Australia, and South America. (yumpu.com)
  • SPREAD OF SUGARCANE APHID IN THE U.S. AND MEXICO The sugarcane aphid was present for many years in the U.S. before becoming a pest of sorghum, having been first discovered in Florida in 1977 on sugarcane. (yumpu.com)
  • This change in behavior may have been due to a host shift in the existing North American populations or the introduction of a new biotype from outside the U.S. Sugarcane aphid is a pest on sorghum in other countries, including Argentina, South Africa, and India. (yumpu.com)
  • gene
  • Sixteen of the 43 genes were identified as potentially associated with aphid resistance through gene annotation analysis. (frontiersin.org)
  • Moreover, we determined that gene expression was related to development, reproduction and immunity to B. bassiana and examined the abundance and composition of bacteria and fungi inside of the body and on the surface of the Q biotype whitefly. (frontiersin.org)
  • pests
  • Aphid is one of the most serious cucumber pests and frequently cause severe damage to commercially produced crops. (frontiersin.org)
  • Coyotes and wolves prey upon livestock Vampire bats drink blood of livestock Eastern grey squirrels are seen as pests in Britain and Ireland because of the decline of red squirrel populations Wild boars damage crops, spread disease, and prey upon livestock Examples of agricultural and horticultural insect pests include: aphids and other Hemipteran pests, thrips, Lepidopteran, Dipteran, and Coleopteran larvae, spider mites, locusts and crickets.

  • eturn to table of contents INTRODUCTION The sugarcane aphid, Melanaphis sacchari, also known as the white sugarcane aphid, has become one of the most important insect pests of sorghum in the Southern United States and Mexico. (yumpu.com)
  • crop
  • This article will discuss the life cycle of the sugarcane aphid, crop damage potential, field scouting, and management practices. (yumpu.com)
  • cultivars
  • I predicted that SBA fitness would be lower at all temperatures on resistant soybeans, but the magnitude of differences between cultivars would not be uniform across temperatures. (k-state.edu)
  • adult
  • Four aphid responses were evaluated: preimaginal development, survival to adulthood, number of progeny produced, and adult longevity. (k-state.edu)
  • Sugarcane aphids: A winged adult, non-winged adults, and nymph. (yumpu.com)
  • economically
  • In 2013, sugarcane aphid was discovered feeding on sorghum with instances of economically significant damage reported in Louisiana and Texas. (yumpu.com)
  • molecular
  • We hope the use of molecular markers to identify biotypes will be available soon so we can take samples in the field and perform quick DNA tests to determine distribution of these biotypes," Hill said. (innovations-report.com)
  • protection
  • Here, we compared the fitness (i.e., the growth and development time, reproduction and protection against Beauveria bassiana ( B. bassiana ) of Q biotype whiteflies fumigated under hO 3 (280 ± 20 ppb) and control O 3 (50 ± 10 ppb) concentrations. (frontiersin.org)
  • damage
  • Sugarcane aphid is capable of causing significant damage and reductions to yield in sorghum. (yumpu.com)
