Tsetse flies are the sole cyclic vectors of African trypanosomes, which cause human and animal African trypanosomiases in Africa. Tsetse fly control remains a promising option for disease management. The sterile insect technique (SIT) stands as an environmentally friendly tool to control tsetse populations.

Article Synopsis
  • Endogenous banana streak virus (eBSV) integrants from Musa balbisiana can reactivate in AAB hybrids, leading to banana streak disease, but not in BB parent lines with similar eBSV loci.
  • Research utilized sequencing to analyze siRNAs, transcripts, and methylation levels in both eBSV-free and eBSV-infected banana plants.
  • The results indicate that eBSV regulation is epigenetic in BB plants, preventing viral activation and contributing to their resistance against viral infections.

Plants have powerful defense mechanisms and extensive immune receptor repertoires, yet crop monocultures are prone to epidemic diseases. Rice (Oryza sativa) is susceptible to many diseases, such as rice blast caused by Magnaporthe oryzae. Varietal resistance of rice to blast relies on intracellular nucleotide binding, leucine-rich repeat (NLR) receptors that recognize specific pathogen molecules and trigger immune responses.

This case report describes the effects of fecal microbiota transplantation (FMT) administered via enema in a 4-year-old spayed, champagne Domestic Ferret () with chronic diarrhea, maldigestion and weight loss. We aimed to establish a protocol for FMT as a novel therapeutic treatment for chronic diarrhea in domestic ferrets. We mapped the fecal microbiome by 16S rRNA gene amplicon sequencing to track the patient's fecal microbiota throughout the treatment and observation period.

The cocoa pod borer (CPB) Conopomorpha cramerella (Snellen) (Lepidoptera: Gracillaridae) is one of the major constraints for cocoa production in South East Asia. In addition to cultural and chemical control methods, autocidal control tactics such as the Sterile Insect Technique (SIT) could be an efficient addition to the currently control strategy, however SIT implementation will depend on the population genetics of the targeted pest. The aim of the present work was to search for suitable microsatellite loci in the genome of CPB that is partially sequenced.
