Summary: In this study, the molecular and insecticidal characteristics of a Bt isolate T405 toxic against Spodoptera frugiperda were investigated. The presence of various Cry and Vip proteins in T405, as well as their corresponding genes, was confirmed. The whole genome sequencing and annotation of T405 revealed the presence of many insecticidal toxin protein coding genes and additional virulence-assisted factors. These findings provide important insights for the development of new strategies for controlling the maize fall armyworm.

Summary: This study investigated the composition and diversity of microbiomes associated with larval specimens of the S. frugiperda corn strain, finding Firmicutes, Proteobacteria, and Bacteroidota as the dominant bacterial phyla. No significant differences were found in bacteria species diversity and richness among the six treatments. Enterococcus spp. were detected in treatments with Bt and antibiotics, suggesting low susceptibility. Endosymbiont Arsenophonus was also identified in treatments with Bt and antibiotics. The results shed light on the little-known interaction between gut microbiota of this pest and Bt endotoxins.

Summary: The detection of fall armyworm in Western Australia in 2020 and the lack of government response may have a significant impact on the state's agriculture. A bioeconomic model estimates that over the next decade, the presence of fall armyworm could cost agricultural producers approximately A$14.2-39.3 million annually by year 10, with damage costs attributed to yield loss and increased variable production costs.

Summary: This study determined the lethal concentration of emamectin benzoate (EMB) on the fall armyworm (FAW) and assessed its sublethal effects on parental and offspring generations. Sublethal concentrations of EMB significantly influenced the life cycle and reproduction characteristics of FAW. These findings have important implications for the rational use of FAW insecticides.

Summary: The fall armyworm is one of the most destructive insect pests in the world, and it has invaded Africa and spread to Asia within two years. Glycerol has been found to play a crucial role in the rapid cold hardening process, and the genes GPDH and GK are associated with glycerol synthesis. RNA interference of these genes resulted in a decrease in survival rate in the fall armyworm larvae. After a cold period, an increase in glycerol accumulation was observed. This research highlights the importance of glycerol as a cryoprotectant for the survival of this quarantine pest during the cold period.

Summary: Fall armyworm (FAW) and southern armyworm (SAW) have become major threats to crops in Africa since 2016. This research identified different parasitoids associated with these pests in Cameroon, with T. remus showing higher parasitism on FAW and C. icipe having faster development time compared to other larval parasitoids.

Summary: The study revealed the presence of natural enemies of fall armyworm in Nigeria, including Euplectrus laphygmae, Telenomus remus, and Trombidium sp., which can serve as more environmentally friendly and cost-effective control methods. Due to the natural control effects of natural enemies on pests, it is recommended to incorporate them into integrated pest management strategies.

Summary: The application of silicon significantly increased mortality and developmental period of fall armyworm, while reducing larval and pupal biomass. It also decreased lipase activity of larvae and fecundity of adults, while prolonging adult longevity. Additionally, silicon had positive effects on plant parameters such as fresh and dry weight, stem length, chlorophyll content, and antioxidant activity.

Summary: The study aimed to determine if plant tissue overlays could detect resistance by using Bt proteins and Bt cotton plant tissue in diet-overlay bioassays. Results showed that overlays using lyophilized tissue from white flowers were most ideal, while tissue from non-Bt bolls and leaves affected larval health and behavior, affecting assay results.

Summary: Research has shown that fall armyworm prefer to oviposit on undamaged corn plants, and larvae that fed on damaged plants exhibited reduced weight and head capsule width. All larval feeding led to significantly increased metabolites and VOC concentrations, primarily driven by linoleic acid and tricarboxylic acids. Additionally, several VOCs with increased concentrations in damaged plants were identified as oviposition deterrents, suggesting potential for use in integrated pest management strategies.

Summary: This study investigates the inheritance of resistance to Cry1A.105 toxin in the corn earworm and finds that it is controlled by a single, autosomal, nonrecessive gene. The nonrecessive nature of the resistance may be an important factor contributing to widespread resistance in maize hybrids containing Cry1A.105 in the United States.

Summary: Maize is a crucial crop in China, but the invasion of fall armyworm (FAW) threatens its sustainable productivity. Various entomopathogenic fungi (EPF) were tested and found to effectively cause mortality in FAW larvae and eggs. Further research on the effectiveness of these EPF in the field may lead to their important role in controlling FAW.

Summary: Feline leishmaniasis (FeL) is now considered an emerging disease in Brazil, with an estimated prevalence of 8% and Leishmania infantum being the most prevalent species. Cats infected with Leishmania typically show skin lesions, mainly in the cephalic region, and diagnosis is primarily conducted through serological tools. However, further research is needed on the immune response and diagnostic methods for FeL in cats.

Summary: The efficiency of RNAi technology varies in insects. This study found that gene silencing can be achieved in the sugarcane borer through feeding with dsRNA, but effective knockdown requires high dosages and long exposure times. The activity of gut nucleases may be one of the factors contributing to the low efficiency of RNAi in this species.

Summary: Schistosomiasis is a neglected tropical disease mainly found in Brazil, where Kato-Katz (KK) thick smear is the recommended screening test. However, KK has limitations in sensitivity. Helmintex (HTX), a magnetic-based method, showed superior performance compared to KK in a moderate endemic area in northeastern Brazil. This study confirms the potential role of HTX in defining true-positive samples and certifying transmission interruption of schistosomiasis.

Summary: In this study, Bacillus thuringiensis (Bt) Cry toxins were screened for their activity against the sugarcane giant borer, Telchin licus licus. Cry1A (a, b, and c) and Cry2Aa showed high toxicity against the larvae of this insect, with Cry1Ac being the most potent. Molecular dynamics and docking analyses provided insights into the potential interactions between Cry1Ac and aminopeptidase N (APN) receptors. These findings contribute to the development of transgenic sugarcane plants resistant to this important agricultural pest.

Summary: Leishmaniases are parasitic diseases that need cheaper, safer, and more effective treatment options. The anti-fungal compound 3carene (3CR) has potential as a treatment for Leishmania, but its hydrophobicity limits therapeutic uses. In this study, micellar systems made from poloxamers were developed to carry 3CR and enhance its activity against Leishmania braziliensis.

Summary: This overview examines the influence of environmental factors, host-related risk factors, and control strategies on the prevalence of soil-transmitted helminthiasis (STH) in different regions of the world. The results showed that factors such as climate, temperature, soil moisture, precipitation, mass drug administration, lack of access to water and sanitation, and non-use of footwear are associated with the prevalence of STH. Socioeconomic factors, low educational level, and wearing shoes are universal factors related to prevalence, regardless of the location studied.
