Imidacloprid is a neonicotinoid insecticide used for managing the Asian citrus psyllid, Diaphorina citri Kuwayama, which serves as vector of phytopathogens causing citrus greening. However, development of resistance to neonicotinoids among populations of D. citri has coincided with occasional control failures in the field.

Gram-stain-negative cells of both strains were motile, chemotactic rods. Phylogenetic analysis of the 16S rRNA gene and predicted amino acid sequences of ribosomal proteins, average nucleotide identities, and alignment fractions suggest the strains HH1 and HH3 represent novel species belonging to the genus .

- Autotrophic organisms have developed various strategies to raise intracellular dissolved inorganic carbon (DIC) levels to enhance CO fixation, particularly in environments where DIC is scarce.
- Recent studies identified new multisubunit membrane complexes in three bacterial species that can effectively elevate intracellular DIC, with homologs found across 17 phyla.
- Research involving a modified strain of E. coli demonstrated that seven different complexes from multiple phyla could rescue the bacteria's growth under low CO conditions and enhance DIC accumulation, indicating the importance of specific subunits for this process.
Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), transmits the causal pathogen of huanglongbing and is a global pest of citrus. D. citri populations exhibit resistance to multiple insecticide modes of action in areas where these chemicals have been overused.

The stability of thiamethoxam resistance was investigated in the laboratory by establishing populations of field-collected, resistant D. citri and rearing them under no insecticide exposure.
