Summary: The sugarcane borer larvae carry microorganisms that can inhibit the growth of fungi in sugarcane stalks, with some yeast and bacterial isolates showing significant inhibition rates against rot-causing fungi. DNA sequencing revealed the similarity of these isolates to bacteria and yeast species known for their potential in biological control and promoting plant growth.

Summary: Intestinal health relies on the integrity and functionality of the intestine, which is influenced by the evolution of absorptive capacity and the co-evolution of the intestinal immune systems and microbiota. Nutrient supply plays a crucial role in this process, with age affecting the efficiency of nutrient extraction by the microbiota.

Summary: This study investigated the chemical treatment of wastewater used for bioinsecticide production by the bacterium Photorhabdus temperata. The results showed that acidic pretreated wastewater performed the best in supporting P. temperata biopesticide production, with improved biomass production, culturable cell count, and oral toxicity against target pests. Acidic hydrolysis was demonstrated to be the unique promising chemical pretreatment for P. temperata bioinsecticide production.

Summary: Microbes in the digestive tracts of insects, such as Enterococcus spp. and Enterobacter spp., play a crucial role in the host's behavior and development. This study found that eradication of Enterococcus spp. in the gut of G. mellonella larvae accelerated the transition from larvae to pupae. The research also revealed the upregulation of immune response genes in pupae and the upregulation of hormone genes in larvae.

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: Brazil is the largest grower of sugarcane in the world and has faced significant challenges from the sugarcane borer. In 2017, Brazil introduced Bt sugarcane as a commercial solution to control the sugarcane borer. This study evaluated the resistance of different populations of the sugarcane borer in Brazil to Cry1Ab and Cry1Ac Bt sugarcane varieties, and found variations in resistance allele frequencies among different regions.

Summary: This study characterized the genetic structure of Diatraea saccharalis populations in Argentina and Brazil, using cytochrome c oxidase subunit I (COI) analysis and next-generation sequencing (NGS). The results revealed high genetic variation between Argentinean and Brazilian populations, but no clear trend based on distance or hosts. The study also identified key proteins related to reproductive traits. These findings provide important information for the development of management strategies for Diatraea saccharalis.

Summary: The study demonstrated that Na-ETS-4 is highly selective for Hg2+ and can exchange over 90% of mercury in the fluid phase. The system with Hg2+/Na+/ETS-4 required more time to reach equilibrium in the presence of Na+ compared to TPA(+). The modeling based on mass action law and Maxwell-Stefan formalism successfully described the kinetic curves of mercury removal.

Summary: The study found that certain species of parasitic flies belonging to the Phoridae attack Atta spp. workers, including excavators, soldiers, and foragers. There had been no previous research on parasitism of non-foraging worker ants. The low rates of parasitism and specificity for certain worker ant castes by different phorid species were discussed in relation to host-parasitoid interactions and size differences.

Summary: This study investigated the effectiveness of four insecticides for controlling Plutella xylostella and their effects on Cycloneda sanguinea. The results showed that spinosad and chlorfenapyr were highly toxic to P. xylostella, while chlorantraniliprole and methomyl were ineffective. Chlorantraniliprole was highly toxic to C. sanguinea, while methomyl and chlorfenapyr were toxic to C. sanguinea when ingested. Spinosad had low toxicity to C. sanguinea, but affected its flight behavior.

Summary: This study investigated the virulence of Metarhizium anisopliae blastospores against Aedes aegypti mosquitoes under laboratory and field conditions. The results showed that blastospores were more effective in killing mosquito larvae in the laboratory, but their virulence decreased over time in field simulations. However, formulating blastospores in vegetable oil could enhance their protection under adverse conditions.

Summary: The study found that compared to the semi-moist diet, the pelleted diet was more stable in water and had lower leaching. Both diets had similar effects on the growth, survival, feed efficiency and conversion rates of octopuses, but the semi-moist diet had higher protein and energy intake rates. The pelleted diet also stimulated higher digestive enzyme activity, promoting nutrient absorption and utilization.
