s are listed in alphabetical order by the last name of the first author. Impact of punctual mutations in the cap gene of Junonia coenia densovirus (JcDNV) on virus assembly and infectivity to Ld 652 cells and Spodoptera littoralis
Aeluropus littoralis belong to poaceae family. It often grows in salty soils. In this study reaction of A. littoralis to rice pathogens (Pyricularia grisea, Rhizoctonia solani and Bipolaris oryzae) was investigated at greenhouse and field conditions under artificial inoculation. These three mentioned fungi were isolated from rice plants and then propagated and separately inoculated on Aeluropus...
Five annonaceous acetogenins, rolliniastatin-1 [structure: see text], rolliniastatin-2 [structure: see text], laherradurin [structure: see text], squamocin [structure: see text], annonacin [structure: see text], and rotenone as a reference, differing in their NADH oxidase inhibition activity, have been evaluated for antifeedant, insecticidal, trypanocidal and cytotoxic effects on insect, mammal...
Spodoptera littoralis, cotton leafworm is a destructive pest for several economic crops. The more use of chemical pesticide the increase this resistance, that lead to discovering new natural pesticides from plant extracts and oils. present search targeted suggest alternative components sources safety ecosystem had ability reduce insect prohibition. experimental results exhibited highly signific...
Chromosomes of Cnemidophorus littoralis, a new species of teiid lizard recently described, were studied. The animals are from a restinga area in Barra de Maricá, RJ. The karyotype presents a diploid number of 2n = 46 chromosomes and a chromosomal sex determination mechanism of the type XX:XY. Nucleolar organizer regions, Ag-NORs, are at the sixth pair of chromosomes; there is variability of siz...
A crude acetone extract and oil of ripe fruits from Melia azedarach L. were evaluated against the 2nd and 4th instar larvae of Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae). Both oil and extract exhibited highly significant growth inhibition at all concentrations tested, while the oil of M. azedarach recorded higher insecticidal activity against both instars than the crude extract. GC...
To determine the possibility of plasmid transfer occurring between strains of Bacillus thuringiensis in infected lepidopterous larvae, Galleria mellonella and Spodoptera littoralis were infected with two or more strains of B. thuringiensis and the resulting bacteria from the dead insects were examined for plasmid transfer. Transfer rates of plasmids coding for crystal production and tetracyclin...
The genus Amphichorda has been recently re-erected as an independent lineage from Beauveria, circumscribed within Cordycipitaceae. However, its phylogenetic relationships with other members of this family remain obscure. In our ongoing efforts to expand the knowledge on diversity culturable ascomycetes Mediterranean Sea, we isolated several specimens Amphichorda. Preliminary sequence analyses r...
Cotton leaf worm, Spodoptera littoralis, is considered one of the most common arthropod pests that contribute to crop devastation cotton. Previously, agricultural were controlled through application chemical insecticides. However, insecticide-resistant insect populations emergence, as well increasing concerns about environmental and human health risks. Venomous animals introduce valuable source...
dna methylation as epigenetic mark plays a key role in normal differential and developmental processes as well as in dynamic gene regulation at the genomic level. to assess dna methylation pattern in different developmental stages of aeluropus littoralis, methylation sensitive amplified polymorphism (msap) was used. methylation and demethylation status at the ccgg recognition site were tracked ...
