Antifungal Effect of Copper Nanoparticles against , an Obligate Symbiont of Ambrosia Beetle.

Copper nanoparticles (Cu-NPs) have shown great antifungal activity against phytopathogenic fungi, making them a promising and affordable alternative to conventional fungicides. In this study, we evaluated the antifungal activity of Cu-NPs against , the causal agent of dieback, and this might be the first study to do so. The Cu-NPs (at different concentrations) inhibited more than 80% of growth and were even more efficient than a commercial fungicide used as a positive control (cupric hydroxide).

Molecular evidence of the avocado defense response to infection: a deep transcriptome analysis using RNA-Seq.

is a novel member of the Ambrosia Clade (AFC) that has been recognized as one of the symbionts of the invasive Kuroshio shot hole borer, an Asian ambrosia beetle. This complex is considered the causal agent of dieback, a disease that has severely threatened natural forests, landscape trees, and avocado orchards in the last 8 years. Despite the interest in this species, the molecular responses of both the host and during the infection process and disease establishment remain unknown.

Characterization of the Exo-Metabolome of the Emergent Phytopathogen sp. nov., a Causal Agent of Dieback.

is the fungal symbiont associated with the ambrosia beetle , a plague complex that attacks avocado, among other hosts, causing a disease named dieback (FD). However, the contribution of to the establishment of this disease remains unknown. To advance the understanding of pathogenicity, we profiled its exo-metabolome through metabolomics tools based on accurate mass spectrometry.

Differential Susceptibility of Bagrada hilaris (Hemiptera: Pentatomidae) to Different Species of Fungal Pathogens.

Bagrada hilaris Burmeister (Hemiptera: Pentatomidae) is a pest of Palearctic origin. Its presence in the United States was first reported in 2008 and in Mexico in 2014; it affects brassica crops. There are practically no reports of natural enemies of B.

Impact of Rearing Conditions on the Ambrosia Beetle's Microbiome.

Ambrosia beetles, along with termites and leafcutter ants, are the only fungus-farming lineages within the tree of life. Bacteria harbored by ambrosia beetles may play an essential role in the nutritional symbiotic interactions with their associated fungi; however, little is known about the impact of rearing conditions on the microbiota of ambrosia beetles. We have used culture-independent methods to explore the effect of rearing conditions on the microbiome associated with , , and , evaluating different media in laboratory-controlled conditions and comparing wild and laboratory conditions.

Draft Genome Sequence of the Phytopathogenic Fungus , the Causal Agent of Dieback.

Here, we report the genome of strain HFEW-16-IV-019, an isolate obtained from Kuroshio shot hole borer (a sp.). These beetles were collected in Tijuana, Mexico, from elm trees showing typical symptoms of dieback.

Logrank test and Interval Overlap Test for Bactericera cockerelli (Hemiptera: Triozidae) under different fertilization treatments for 7705 tomato hybrid.

It is known that some nutrients can have both negative and positive effects on some populations of insects. To test this, the Logrank test and the Interval Overlap Test were evaluated for two crop cycles (February-May and May-August) of the 7705 tomato hybrid, and the effect on the psyllid, Bactericera cockerelli (Sulc.) (Hemiptera: Triozidae), was examined under greenhouse conditions.
