Non-targeted metabolomics reveals differences in the gut metabolic profile of the fall armyworm strains when feeding different food sources

Substantially altered bacterial diversity associated with developmental stages of litchi stink bug, Tessaratoma javanica (Thunberg) (Hemiptera: Tessaratomidae)

“…Developmental stages of insects, host plant associations, and associated ecological factors can all have an impact on the diversity and abundance of microorganisms [ 6 , [19] , [20] , [21] , [22] ]. Ultimately, relationships might continue over the necessary evolutionary time to permit the selection and establishment of true gut residents, which would not be possible due to the considerable diversity in the microbial community caused by host plants [ 23 ].…”

Influence of plant defense signaling and innate insect metabolic differences to the overall performance of fall armyworm (Spodoptera frugiperda) corn and rice strains on maize as a host

“…In accordance with its extensive spread, this pest has been documented on more than 350 plant species, although it is best known to feed on agriculturally significant grasses such as maize (corn), rice and sorghum. Interestingly, a marked level of genetic differentiation has been reported between FAW populations isolated from corn and rice fields (Kergoat et al 2012; Oliveira et al 2022), and these have accordingly been named as the corn strain and the rice strain. Corn strain larvae are often associated with corn, sorghum and cotton plants, while the rice strain association is more prominent in fields of rice and forage grasses.…”
