Isolation of Microsatellite Loci from the Onion Thrips, Thrips tabaci
Thrips tabaci Lindeman (Thysanoptera: Thripidae), a cosmopolitan pest insect, is subdivided into at least three genetic lineages that have different biological characters, such as reproductive mode and resistibility to insecticides. Since the lineages are discriminated only by mitochondrial DNA, there is a possibility of gene flow among lineages at the genomic level. Nine polymorphic microsatel...
متن کاملfirst detection of pantoea ananatis, the causal agent of bacterial center rot of onion in morocco
pantoea ananatis is an important pathogen causing bacterial center rot in onion. isolated strains from onion soft rot bulbs based on morphological characteristics were tested for hypersensitivity reaction on tobacco. pathogenic strains underwent some biochemical tests which detected the presence of p. ananatis, based on rna16s sequencing, this result was confirmed. symptoms were reproduced by i...
متن کاملPyrethroid-resistant onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), infesting persimmon fruit
A total of 53 strains of onion thrips, Thrips tabaci Lindeman, were established, of which 14 strains were collected from persimmon fruit and 39 strains from a vetch weed, Vicia angustifolia, in commercial persimmon orchards in Wakayama Prefecture. Susceptibility to insecticides was evaluated by the Petri dish-spraying tower method. Pyrethroid-resistant strains and pyrethroid-susceptible strains...
متن کاملDraft Genome Sequences of the Onion Center Rot Pathogen Pantoea ananatis PA4 and Maize Brown Stalk Rot Pathogen P. ananatis BD442
Pantoea ananatis is an emerging phytopathogen that infects a broad spectrum of plant hosts. Here, we present the genomes of two South African isolates, P. ananatis PA4, which causes center rot of onion, and BD442, isolated from brown stalk rot of maize.
متن کاملDevelopment and Use of a Dynamic Sequential Sampling Program for Onion Thrips., Thrips tabaci (Thysanoptera: Thripidae)., on Onions
J. Econ. Entomol. 80(5): 1051-1056 (1987) ABSTRACT Data collected in 1983 from six commercial onion fields in upstate New York indicate that dispersion characteristics of onion thrips (OT), Thrips tabaci Lindeman, are precisely described by Taylor's power law (S2 = amb), with Ina = 0.517, SIn, = 0.059, b = 1.89, and Sb = 0.028 (n = 47; r2 = 0.99: P :$ 0.0001). Additionally, during the main peri...
