Population Dynamics of Criconemoides simile on Soybean.
نویسندگان
چکیده
Custer and Hood soybean cultivars were inoculated with nine levels of Criconemoides simile ranging from 300 to 20,600 nematodes per plant. Rate of reproduction decreased as inoculum level was increased beyond 900-2,000 nematodes. Final population density was influenced by both composition and level of inoculum. There was an indication that substance(s). inhibitory to larvae, accumnlated in soil in which Hood was grown for 11 months, Significant reduction of fresh weight of roots of Hood, but not Custer, occurred at population densities of 37,000 and 44,700 nematodes per plant.

Reproduction of Criconemoides simile, Helicotylenchus pseudorobustus, and Paratylenchus projectus on Soybean.
Reproduction of Criconernoides simile, Paratylenchus projectus, and Helicotylenchus pseudorobustus, alone and in certain combinations, was characterized during 50 days on the soybean cultivars Custer and Hood. Custer was the more suitable host for all three nematodes and C. simile was the most vigorous parasite on both cultivars. C. simile and H. pseudorobustus reproduced as well in combination...

Seasonal fluctuations in field populations of Meloidogyne incognita, Pratylenchus zeae, P. brachyurus, Criconemoides ornatus, Trichodorus christiei, and Helicotylenchus dihystera on monocultured corn, cotton, peanut, and soybean were determined monthly for 4 yr. Population densities of M. incognita were greater in corn and cotton plots than in peanut and soybean plots from July until January. T...
متن کاملCorrelations of field populations of nematodes with crop growth responses for determining relative involvement of species.
Treated and nontreated field plots were assayed, and the population density of each plant-parasitic nematode present was compared with crop growth and yield and with the population densities of other nematode species in the same plots. The strongest correlations between nematode population densities and growth responses occurred when soil assays for nematodes were made 55-73 days after planting...
متن کاملInfluence of Potassium Availability on Soybean Aphid Population Dynamics
The soybean aphid, Aphis glycines was first observed in Wisconsin during the 2000 growing season. Since its introduction many commercial soybean fields have exhibited high levels of aphid activity and yield losses have been widely reported from aphid feeding damage. Field observations of heavy soybean aphid infestations have suggested a potential link between potassium deficiency in soybeans an...

Edamame are soybeans harvested at a physiologically immature (R6) stage as a specialty food item for fresh and processed (frozen) markets. The soybean aphid, Aphis glycines Matsumura, is a newly introduced insect pest of soybeans in North America. This field study was to provide baseline information on the impact of A. glycines on the edamame soybean. This study determined the in 2005 did not e...
