Root rot disease significantly reduces the medicinal quality of Coptis chinensis . In present study, results found that C. fibrous and taproot have different tactics in response to pathogen infection. Diaporthe eres , Fusarium avenaceum solani were isolated identified cause degrees root rot. These are helpful for researchers further explore mechanism resistance rhizoma
Abstract The small brown planthopper (Laodelphax striatellus (Fallén), Hemiptera: Delphacidae), is an important agricultural pest of rice, and neonicotinoid insecticides are commonly used for controlling L. striatellus. However, the sublethal effects thiamethoxam on remain relatively unknown. In this study, age-stage life table procedure was to evaluate biological parameters Additionally, activities carboxylesterase, glutathione S-transferase, cytochrome P450 monooxygenase in third instar...
Baculoviruses are insect-specific pathogens. Novel baculovirus isolates provide new options for the biological control of pests. Therefore, research into characteristics newly isolated baculoviruses, including accurate classification and nomenclature, is important. In this study, a was from Mythimna separata its complete genome sequence determined by next-generation sequencing. The double-stranded DNA 153 882 bp in length, encoding 163 open reading frames. virus identified as variant...
The Cydia pomonella granulovirus (CpGV) GP37 has synergistic effects on the infectivity of nucleopolyhedroviruses (NPVs), however, mechanism employed is unclear. In this study, in vitro and vivo binding assays indicated that efficiently bound to midgut peritrophic membrane (PM) Spodoptera exigua larvae. Treatment with led damage PM’s compacted structure generation PM perforations, enhancement permeability. qPCR results further demonstrated increased ability occlusion-derived virions (ODV)...
Outbreaks of leaf spot disease occurred in Rehmannia glutinosa fields Henan Province, China, 2019, with the incidence ranging from 20% to 40%. R. plants diseased leaves were collected, and 25 isolates obtained. Pathogenicity tests, morphological observations, phylogenetic analyses conducted identify pathogens, biological characteristics control agents pathogens studied. Five pathogenic fungi isolated. Three identified as Fusarium equiseti, which is a new pathogen causing disease; other two...
Abstract BACKGROUND Combined use can be an effective measure to improve pest control by viruses and parasitic wasps. However, not all combinations of natural enemies show improved effects. Helicoverpa armigera nucleopolyhedrovirus (HearNPV) Campoletis chlorideae Uchida are two important . This study aimed investigate the combined effects C. HearNPV against H. larvae impact on RESULTS The combination exerted increased mortality when parasitized one day after infection with HearNPV. could...
Abstract Root rot is a destructive soil-borne disease of Coptis chinensis , which depends on chemical control at present, and more attention should be paid to biocontrol disease. In the present research, isolate Y9 isolated from healthy root samples was identified as Bacillus cereus. Further screening pot experiments showed that B. cereus inhibited growth main causal agents coptis ( Fusarium solani F. avenaceum ) seven other phytopathogenic fungi. The application compatible Trichoderma...
Leaf blight outbroke in Rehmannia glutinosa plantation Wenxian county, Henan province 2019. R. plants with diseased leaves were collected from the plantation, and three strains isolated leaf samples. Pathogenicity test, morphological observation, phylogenetic analysis of ITS, EF1-α, Tub suggested that they respectively Fusarium proliferatum, F. oxysporum, F.acuminatum. Among them, acuminatum, as a pathogen disease, had never been reported. To clarify biological characteristics this study...
