Laboratory Selection and Assessment of Resistance Risk in (Diptera: Drosophilidae) to Spinosad and Malathion.

(Matsumura) is one of the most economically important pests of soft-skinned fruits worldwide. Repeated insecticide applications commonly used to prevent fruit infestations increase the risk of resistance development in . Assessment of resistance risk in using artificial selection can be valuable in developing proactive resistance management strategies to retain susceptibility in the field populations.

Sclerotinia sclerotiorum utilizes host-derived copper for ROS detoxification and infection.

Necrotrophic plant pathogen induces host reactive oxygen species (ROS) production, which leads to necrosis in the host, allowing the pathogen to absorb nutrients from the dead tissues. Sclerotinia sclerotiorum is a typical necrotrophic pathogen that causes Sclerotinia stem rot in more than 400 species, resulting in serious economic losses. Here, we found that three S.

Insecticide residue longevity for on-site screening of Drosophila suzukii (Matsumura) resistance.

Background: Preventative application of insecticides reduces marketable yield losses caused by Drosophila suzukii females that selectively lay eggs into ripe and ripening fruits. However, repeated applications of insecticides increase the risk of resistance development. It is therefore critical to test field-collected flies on-site to assess the level of sensitivity of D.

Simultaneous Transcriptome Analysis of Host and Pathogen Highlights the Interaction Between Brassica oleracea and Sclerotinia sclerotiorum.

White mold disease caused by Sclerotinia sclerotiorum is a devastating disease of Brassica crops. Here, we simultaneously assessed the transcriptome changes from lesions produced by S. sclerotiorum on disease-resistant (R) and -susceptible (S) B.

DNA Methylation Alterations at 5'-CCGG Sites in the Interspecific and Intraspecific Hybridizations Derived from Brassica rapa and B. napus.

DNA methylation is an important regulatory mechanism for gene expression that involved in the biological processes of development and differentiation in plants. To investigate the association of DNA methylation with heterosis in Brassica, a set of intraspecific hybrids in Brassica rapa and B. napus and interspecific hybrids between B.

Identification of genomic regions involved in resistance against Sclerotinia sclerotiorum from wild Brassica oleracea.

The lack of resistant source has greatly restrained resistance breeding of rapeseed (Brassica napus, AACC) against Sclerotinia sclerotiorum which causes severe yield losses in rapeseed production all over the world. Recently, several wild Brassica oleracea accessions (CC) with high level of resistance have been identified (Mei et al. in Euphytica 177:393-400, 2011), bringing a new hope to improve Sclerotinia resistance of rapeseed.
