Abstract:
Insects
and microbes have established complex symbiotic relationships during their long
co-evolutionary history. Host-associated microbiota can affect the spread and
outbreaks of their hosts by manipulating host phenotype or ecological
adaptation, especially in invasive pest species. In turn, both host genotypes
and environmental factors shape the structure and function of host-microbiota
during the invasion process. Thus, understanding the processes that drive the
leaf miner microbiotic assembly is imperative for understanding the invasion
process and potential for damage of this invasive species. Leaf miner Liriomyza flies cause severe damage to
numerous ornamental and vegetable crops. Three highly polyphagous leaf miner
species, L. trifolii, L. sativae and L. huidobrensis, have now spread to multiple regions of China and
have become the dominant pest of numerous ornamental and vegetable crops,
posing a major threat to agricultural production. In this paper, we summarize
current research on the status, diversity, composition, community assembly and
function, of the bacterial microbiota of invasive leaf miners. This information
provides a foundation for understanding interactions between leaf miners and
their bacterial microbiota, and for designing environmentally-friendly,
efficient pest control strategies by targeting these endosymbionts.
