Soybean leaf age and plant stage influence expression of resistance to velvetbean caterpillar and fall armyworm
(2021-01-01)
Numerous species of herbivorous insects are associated with soybeans, including the specialist velvetbean caterpillar (VBC), Anticarsia gemmatalis, and the generalist fall armyworm (FAW), Spodoptera frugiperda. Expression ...
Histological analysis of resistant and susceptible eucalyptus plants inoculated with Ceratocystis fimbriataAnálise histológica de plantas de eucalipto resistentes e suscetíveis inoculadas com Ceratocystis fimbriata
(2018-06-01)
The genus Ceratocystis includes several species distributed throughout the world. A plant infected with this fungus presents as primary symptoms the darkening of the vascular system and as secondary symptoms wilt, dryness ...
Silicon and acibenzolar-s-methyl to induce resistance against Bemisia tabaci biotype B and the effects on common bean plants
(2018-03-01)
Present study is aimed to evaluate the effects of silicon and acibenzolar-s-methyl (ASM) application on the oviposition/feeding preference of the whitefly, Bemisia tabaci biotype B during development of bean plants. A ...
Possible involvement of the phloem sealing system in the acceptance of a plant as host by an aphid
(Birkhauser Verlag AG, 1996)
Possible reasons for the rejection of some lines of Triticum monococcum (Tm44 and Tm46) by the aphid Sitobion avenae were explored. In all T. monococcum lines studied, whether unfavourable (non-host/resistant plant) or ...
Plant Silicon Amendment Does Not Reduce Population Growth of Schizaphis graminum or Host Quality for the Parasitoid Lysiphlebus testaceipes
(2020-01-01)
Interactions between different pest control methods can affect Integrated Pest Management efficiency. This study sought to evaluate (1) if Si accumulation is related to the level of constitutive resistance in sorghum ...
Protein identification before and after glyphosate exposure in Lolium multiflorum genotypes
(Wiley-Blackwell, 2018-05-01)
BACKGROUNDWeeds reduce crop yields, and among the methods used to control these plants, the use of chemicals is preferred. However, the repeated application of herbicides with the same mechanism of action selects for ...
Screening of plant growth-promoting traits in arsenic-resistant bacteria isolated from the rhizosphere of soybean plants from Argentinean agricultural soil
(Springer, 2012-12)
Aims: The purpose of this study was to investigate plantgrowth promoting traits in native and arsenic (As) highly-resistant bacterial strains isolated from the rhizosphere of soybean (Glycine max) plants grown in an ...
Effect of storage temperature and bean genotypes on the resistance to Acanthoscelides obtectus (Say) (Coleoptera : Bruchidae)
(Entomological Soc Brasil, 2004-05-01)
Aiming to evaluate the effect of different temperatures of storage and bean genotypes, Phaseolus vulgaris L., on the expression of resistance to the bean weevil, Acanthoscelides obtectus (Say), tests were carried out with ...
Characterization of resistance to the bean weevil Acanthoscelides obtectus Say, 1831 (Coleoptera: Bruchidae) in common bean genotypes
(Springer, 2017-12-01)
The bean weevil Acanthoscelides obtectus (Say, 1831) (Coleoptera: Bruchidae) is one of the most serious pests of stored beans worldwide because of the damage it causes to grains within warehouses. The use of resistant ...
Influence of plant resistance at the third trophic level: Interactions between parasitoids and entomopathogenic fungi of cereal aphids
(1998)
Host-plant resistance can affect herbivorous insects and their natural enemies such as parasitoids and entomopathogenic fungi. This tritrophic effect acts on interspecific interactions between the two groups of natural ...
