Aphis glycines; Glycine max; crop production; cultivars; genotype; insect pests; seeds; soybeans; Nebraska
Abstract:
... The soybean aphid, Aphis glycines Matsmura, has become the most significant soybean [Glycine max (L.) Merrill] insect pest in the north central soybean production region of North America. The objectives of this research were to measure selected genotypes for resistance to the soybean aphid in the later vegetative and reproductive stages under field conditions, and confirm the presence of tolerance ...

Abstract:
... Use of plant secondary metabolic compounds is an important method for insect pest control. In this study, the survival, development, and reproduction of Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) MEAM1 cryptic species were compared over two consecutive generations on three cotton cultivars of different gossypol levels. Both cotton cultivar and generation significantly affected the fitness ...

Abstract:
... Fifty-nine sweetpotato cultivars, including 16 heirlooms, 11 near-heirlooms (developed in the 1960s and 1970s), 19 cultivars from the 1980s, and 13 modern varieties (since 1990), were evaluated for resistance to soil insects in field experiments during 2010–2011 at the U.S. Department of Agriculture-Agriculture Research Service, U.S. Vegetable Laboratory (USDA-ARS, USVL), Charleston, SC. These exp ...

Aphis glycines; Glycine max; biotypes; cultivars; evolution; genes; germplasm evaluation; host plants; insect pests; pest resistance; soybeans; Midwestern United States
Abstract:
... While soybean cultivars with resistance to the soybean aphid (Aphis glycines Matsumura) have been commercially released, the presence of virulent biotypes capable of overcoming plant resistance threatens the durability of host-plant resistance as a stable management tactic. Novel sources of host plant resistance (HPR) are needed to combat rapid biotype evolution. In this study, we screened 1,021 s ...

Abstract:
... Plant expression of the entomopathogenic bacteria Bacillus thuringiensis cry gene has reduced the damage created by insect pests in several economically important cultures. For this study, we have conducted genetic transformation of the indica rice ‘IRGA 424,’ via Agrobacterium tumefaciens, using the B. thuringiensis cry1Aa and cry1B genes, with the objective of obtaining rice plants resistant to ...

Abstract:
... Crucifer-feeding flea beetles, Phyllotreta spp., are chronic insect pests in Canadian prairie canola production. Multiple laboratory and field feeding bioassays were conducted to determine the susceptibility of a wide range of crucifer species, cultivars, and accessions to feeding by flea beetles with the goal of discovering sources of resistant germplasm. In 62 bioassays of 218 entries, no consis ...
