“…This suggests that the composition of wax has a high degree of variability. In addition, we identified 157 different wax metabolites, which is significantly more than the 25 metabolites identified in a previous study [ 14 ]. Interestingly, we found naphthalene and isophorone were the two most abundant metabolites in the wax samples, which are two metabolites reported as being associated with insect resistance in plants [ 29 , 30 , 31 , 32 , 33 ].…”

“…Naphthalene is one of the ingredients of insect repellents [ 37 , 38 ], while isophorone can be found in an insect attractant [ 39 , 40 , 41 ], which may suggest that metabolites isolated, purified and formulated from sugarcane wax could be used to control sugarcane borers. In addition, Wartha (2022) reported that specific sugarcane wax metabolites were associated with insect resistance of sugarcane germplasm [ 14 ]. Thus, these metabolites could be used as parameters or indicators to evaluate the ability of the sugarcane resistance to insects.…”

“…Furthermore, some wax metabolites, such as alcohols and short-length chain aldehydes, have resistance to stalk borers [ 12 , 13 ]. More recently, Wartha et al (2022) identified some components of sugarcane epicuticular wax and used these metabolites to classify the genotypes susceptible or resistant to the initial attack of sugarcane borers ( Diatraea saccharalis ) [ 14 ]. Therefore, it is of prospect to study the composition of sugarcane epicuticular wax and its effect of insect resistance.…”

Sugarcane wax has the potential to be utilized as a novel natural insecticide, which could help to reduce the large yield losses caused by agricultural pests. By employing the gas chromatography–mass spectrometry (GC-MS) approach, we conducted a study to analyze the composition of epicuticular wax from the rind of the sugarcane variety YT71210. A total of 157 metabolites, categorized into 15 classes, were identified, with naphthalene, a metabolite with insect-resistant properties, being the most prevalent. The feeding trial experiment suggested that sugarcane wax is toxic to silkworms by impacting the internal organs. Intestinal microbial diversity analysis suggested that the abundance of Enterococcus genus was significantly increased in both ordure and gut of silkworm after wax treatment. The results indicated that the feeding of wax has an adverse effect on the gut microbial composition of silkworms. Our findings lay a foundation for the efficacy of sugarcane waxes as a valuable natural insecticide and for the prediction of promising sugarcane varieties with insect resistance.

“…Ordered predictors selection adapted for classification models (OPSDA) , was performed to find more interpretative variables and improve the classification methods, enhancing specificity and selectivity. The classification methods were evaluated regarding sensitivity, specificity, and classification error, as presented in eqs –. Sensitivity = TP TP + FN Specificity = TN TN + FP Error = FP + FN TP + TN + FP + FN Here, TP is the true positive, TN is the true negative, FP is the false positive, and FN is the false negative.…”

Oral squamous cell carcinoma (OSCC) is the prevalent type of oral cavity cancer, requiring precise, accurate, and affordable diagnosis to identify the disease in early stages, Comprehending the differences in lipid profiles between healthy and cancerous tissues encompasses great relevance in identifying biomarker candidates and enhancing the odds of successful cancer treatment. Therefore, the present study evaluates the analytical performance of simultaneous mRNA and lipid extraction in gingiva tissue from healthy patients and patients diagnosed with OSCC preserved in TRIzol reagent. The data was analyzed by partial least-squares discriminant analysis (PLS-DA) and confirmed via matrixassisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI). The lipid extraction in TRIzol solution was linear in a range from 330 to 2000 ng mL −1 , r 2 > 0.99, intra and interday precision and accuracy <15%, and absolute recovery values ranging from 90 to 110%. The most important lipids for tumor classification were evaluated by MALDI-MSI, revealing that the lipids responsible for distinguishing the OSCC group are more prevalent in the cancerous tissue in contrast to the healthy group. The results exhibit the possibilities to do transcriptomic and lipidomic analyses in the same sample and point out important candidates related to the presence of OSCC.

“…Resistance to borers in sugarcane manifests in leaves or stems, impeding or retarding larval ingress into the stalks (Kvedaras et al 2007). Traits linked to leave, such as narrow leaves, leaf shedding, erect leaves, long leaf spindles, low leaf senescence, and those related to stems, including high fiber content, light stalk color, heavy wax coating, thin stalks, high vigor, high juice content, and rind hardness and epicuticular wax composition, have served as criteria for ranking entries based on their resistance to borers (Long and Hensley 1972;Ngwuta 2015;Reagan and Mulcahy 2019;de Mello et al 2020;Wartha et al 2022;Penn and Read 2023). The selection of numerous resistant sugarcane cultivars has been facilitated by these pivotal resistance traits.…”

Lepidopteran borers stand out as the most destructive pests in sugarcane, leading to reductions in stalk weight, juice quality and sugar recovery. Presently, integrated pest management (IPM) systems are utilized for sugarcane borer management, employing diverse methods encompassing cropping system, chemical pesticides, behavioral manipulation, biological agents and the selection of resistant varieties. However, the effectiveness of this strategy remains controversial due to concerns about harmful residues, formulation limitations, environmental variability, labor shortages and increased input costs. Currently, multiple lines of transgenic sugarcane expressing insecticidal genes from the bacterium Bacillus thuringiensis (Bt) have been developed globally, offering the prospect of increases production with reduced pesticides application, thereby eliminating the negative effect of IPM. In Brazil, the first genetically modified sugarcane cultivars resistant to the sugarcane borer have been approved and released for commercial cultivation, shedding a bright light on a viable solution for sugarcane borers. This paper reviews borer species and distribution, the significant damage caused by sugarcane borers, current control approaches and the future effective control strategies. Additionally, this work provides comprehensive understanding on Bt sugarcane, serving as an additional tool to complement conventional sugarcane borers control resistance programs.
