“…Amino acids are essential for the development of insects, although requirements differ with respect to insect species. Conversely, in some cases, individual amino acids can also show toxic effects for herbivores 29,30 . In our study, parasitoid performance correlated positively with www.nature.com/scientificreports www.nature.com/scientificreports/ β-cyano-L-alanine and arginine, with the later previously found to be an essential requirement for rearing different parasitoid species in artificial media 31 .…”

Plant nutritional quality can influence interactions between herbivores and their parasitoids. While most previous work has focused on a limited set of secondary plant metabolites, the tri-trophic effects of overall phenotypic resistance have been understudied. Furthermore, the joint effects of secondary and primary metabolites on parasitoids are almost unexplored. in this study, we compared the performance and survival of the parasitoid species Asecodes parviclava thompson on wild woodland strawberry (Fragaria vesca L.) genotypes showing variation in resistance against the parasitoid's host, the strawberry leaf beetle (Galerucella tenella L.). Additionally, we related the metabolic profiles of these plant genotypes to the tritrophic outcomes in order to identify primary and secondary metabolites involved in regulating plant potential to facilitate parasitism. We found that parasitoid performance was strongly affected by plant genotype, but those differences in plant resistance to the herbivore were not reflected in parasitoid survival. These findings could be explained in particular by a significant link between parasitoid survival and foliar carbohydrate levels, which appeared to be the most important compounds for parasitism success. The fact that plant quality strongly affects parasitism should be further explored and utilized in plant breeding programs for a synergistic application in sustainable pest management.

“…Glucose levels were elevated in mutant female adults; the reason for this may be that female mutants need energy to maintain normal life activities, such as mating and spawning [ 57 ]. Studies have shown that many insects need to use proteins and carbohydrates to synthesize sufficient lipids; as a result, insects can reach sexual maturity and lay eggs [ 58 , 59 , 60 ].…”

Global warming poses new challenges for insects to adapt to higher temperatures. Trehalose is the main blood sugar in insects and plays an important role in energy metabolism and stress resistance. The transmembrane transport of trehalose mainly depends on the trehalose transporter (TRET1). Plutella xylostella (L.) is a worldwide agricultural pest; however, the effects of the trehalose transport mechanism and trehalose distribution in tissues on the development, reproduction and temperature adaptation of P. xylostella have yet to be reported. In this study, PxTret1-like was cloned and analyzed regarding its expression pattern. It was found that the expression of PxTret1-like was affected by ambient temperature. The knockout mutation of PxTret1-like was generated using a CRISPR/Cas9 system by targeted knockout. The trehalose content and trehalase activity of mutant P. xylostella increased at different developmental stages. The trehalose content increased in the fat body of the fourth-instar P. xylostella, and decreased in the hemolymph, and there was no significant change in glucose in the fat body and hemolymph. Mutant strains of P. xylostella showed a significantly reduced survival rate, fecundity and ability to withstand extreme temperatures. The results showed that PxTret1-like could affect the development, reproduction and temperature adaptability of P. xylostella by regulating the trehalose content in the fat body and hemolymph.

“…Previous studies showed that the growth and survival rates of herbivorous insects were closely related to the quality of food . The abundance of amino acids, proteins, lipids, and carbohydrates in food are essential for growth of herbivorous insects . For example, free amino acids present in plants were the only source of these nutrients for phloem-feeding insects .…”

Aphis gossypii and Helicoverpa armigera are two important agricultural pests in cotton plants. However, whether early colonization of A. gossypii affects subsequent H. armigera is unknown. We implemented ecological experiments to reveal that A. gossypii-damaged cotton plants [Bacillus thuringiensis (Bt) and non-Bt] had a significant avoidance effect on the oviposition preference of H. armigera adults. However, A. gossypii-damaged cotton plants (non-Bt) increased the weight and pupation rate and reduced the mortality of H. armigera larvae. Transcriptomic and metabolomic analyses showed that 13 and 9 genes were significantly upregulated to be involved in salicylic acid (SA) and indole acetic acid (IAA) biosynthesis, and SA and IAA contents were significantly increased, respectively. However, 15 genes involved in jasmonic acid (JA) biosynthesis were significantly downregulated as a result of the antagonism of SA and JA. Moreover, there was significant upregulation in multiple genes involved in the biosynthesis of L-histidine, fructose, maltotetraose, melezitose, lecithin, stearidonic acid, and mannitol, in which metabolites were confirmed to promote the growth and development of H. armigera. Our study is a reference for investigating the evolutionary relationships and provides insights into implementing effective insect biocontrol between H. armigera and A. gossypii.
