“…Such climate changes present a major challenge for poikilotherms such as insect herbivores [ 3 ]. Most previously published studies have found that increases in atmospheric temperature directly affect life cycles, phenology, behavior, and distribution of insect herbivores, or indirectly affect insects through other factors that respond to temperature-induced changes [ 4 , 5 , 6 , 7 ]. For example, even moderate increases of ambient temperature can enhance the population growth rates of some insect herbivores, resulting in more generations per year [ 8 , 9 ].…”

Aphid performance is sensitive to temperature changes. Previous studies found that Acyrthosiphon gossypii (Mordviiko) was more sensitive to high temperature than Aphis gossypii (Glover). However, the effects of high temperatures on the survival, fecundity, and feeding behavior of these two aphid adults are not clear. This study examined the effect of different temperatures (29 °C, 32 °C, and 35 °C) on the adult survival rate, fecundity, and feeding behavior of these two aphid species. Our results showed that the adverse effects of high temperatures (32 °C and 35 °C) on aphid adult survival and fecundity were greater for Ac. gossypii than Ap. gossypii. The electrical penetration graph (EPG) data showed that Ac. gossypii spent more time feeding on xylem than phloem under all temperature treatments, which contrasted with Ap. gossypii. The time of phloem ingestion by Ap. gossypii at 32 °C was significantly higher than at 29 °C, while for Ac. gossypii, this value significantly decreased when temperature increased. These feeding patterns indicate that Ac. gossypii obtains less nutrition from phloem in support of its development and fecundity. Data generated in this study will serve as the basis for predicting the effects of increased temperature on these two cotton aphids.

“…We found no significant difference in glycogen content and trehalose content between ZK-PI-5 and ZK-PI-9 treatment and the group in this study. While past studies have shown that trehalose is hydrolyzed by trehalase to produce glucose ( Li et al, 2021 ), and glucose on uridine diphosphate glucose completes the last step of glycogen synthesis under the action of glycogen synthase ( Wang et al, 2020 ; Liu et al, 2022 ). Through past experiments, we also found that trehalase activity inhibition have prevented trehalose from converting to glucose, and glucose content has been decreased.…”

“…As an immediate energy source, it plays a vital role, such as providing energy during flight ( Elbein et al, 2003 ; Shukla et al, 2015 ). Trehalose is hydrolyzed glucose to provide energy for the biological organism ( Wang et al, 2020 ). In this process, due to high specificity for trehalase, it is competitively inhibited by most glycosidase inhibitors ( Shukla et al, 2015 ; Tang et al, 2018 ).…”

Introduction:Spodoptera frugiperda is an omnivorous agricultural pest which is great dangerous for grain output.Methods: In order to investigate the effects of potential trehalase inhibitors, ZK-PI-5 and ZK-PI-9, on the growth and development of S. frugiperda, and to identify new avenues for S. frugiperda control, we measured the content of the trehalose, glucose, glycogen and chitin, enzyme activity, and gene expression levels in trehalose and chitin metabolism of S. frugiperda. Besides, their growth and development were also observed.Results: The results showed that ZK-PI-9 significantly reduced trehalase activity and ZK-PI-5 significantly reduced membraned-bound trehalase activity. Moreover, ZK-PI-5 inhibited the expression of SfTRE2, SfCHS2, and SfCHT, thus affecting the chitin metabolism. In addition, the mortality of S. frugiperda in pupal stage and eclosion stage increased significantly after treatment with ZK-PI-5 and ZK-PI-9, which affected their development stage and caused death phenotype (abnormal pupation and difficulty in breaking pupa).Discussion: These results have provided a theoretical basis for the application of trehalase inhibitors in the control of agricultural pests to promote future global grain yield.

“…Laboratory measurements of life parameters usually take place under controlled conditions at single constant temperatures, while field conditions are much more complex with climatic conditions fluctuating over time and space [53,68]. As insects are ectothermic organisms, their responses to constant and fluctuating temperature can vary widely [69][70][71][72][73]. Under controlled conditions in a laboratory, Mu et al [74] showed that the development of C. pallens larvae was 10 to 12 days.…”

Banker plant systems can be used to sustain a reproducing population of biological control agents (BCAs) within a crop, thus providing long-term pest suppression. The founder population of natural enemies in banker plant systems is usually mass-reared on factitious hosts. Thus, a better understanding of the population fitness and pest control performance of mass-reared BCAs in the field is crucial when developing integrated pest management (IPM) strategies. In this study, we determined the fitness of the generalist predator, Chrysopa pallens (Hemiptera: Chrysopidae) ever cultured on different food sources (i.e., mass rearing food, Corcyra cephalonica eggs, and aphid food, Megoura japonica) preying on Aphis craccivora in a banker plant system in a greenhouse based on Chi’s age-stage, two-sex life table analysis method. The life tables and predation rate parameters of C. pallens were not significantly different between both treatments under fluctuating temperature conditions. Corcyracephalonica eggs did not significantly weaken the performances of C. pallens in a Vicia faba–A. craccivora banker plant system compared to aphids. In conclusion, C. cephalonica eggs can be used for the mass production of C. pallens as the founder population in a banker plant system. Moreover, linking the life table data with the predation rate is an effective strategy for evaluating mass rearing programs in establishing banker plant systems.
