Disturbed state concept (DSC) theory maintains that the observed actual response (AR) of material under loading effects is composed of and determined by two reference state responses, namely relative intact (RI) state response and fully adjusted (FA) state response. Hardening material shows macroscopic behavior characteristics of RI response and shows negligible mesoscopic structure changes. Pore water pressure dissipation in macroscopic experiment or variance of computerized tomography (CT) value in mesoscopic experiment, as chosen characteristic parameters, can be introduced to the evolution function of disturbance factor to revise response of hardening to be response of softening. RI behavior is constituted via using hardening model. The characteristic parameters are extracted from regulations which exist in macroscopic or mesoscopic experimental data of softening material. DSC approach strategy on response prediction is presented through the combination of characteristic parameters and hardening constitutive model within the procedure of softening response prediction.

“…For reproductive development, longhorn beetles obtain supplemental nutrition by feeding on special host plants after eclosion. In addition, suitable host plants for oviposition are selected for the survival of offspring (Allison et al., 2004; Zheng et al., 2022). During host selection, adults are attracted by the odorous compounds produced by appropriate host plants (Yang et al., 2011b; Zheng et al., 2022).…”

Batocera horsfieldi (Hope) (Coleoptera: Cerambycidae) is an important pole borer pest. It causes serious harm to various hosts, particularly Juglans regia L. (Juglandaceae). In this study, headspace solid‐phase microextraction (HS‐SPME), gas chromatography–mass spectrometry (GC–MS), and electroantennogram (EAG) responses were combined to examine the mechanism by which B. horsfieldi adults locate their host, J. regia. The results showed that J. regia contained 65 volatile compounds in all, with 36 and 42 volatile substances in bark and leaves, respectively. Moreover, terpenes accounted for the largest relative content among the volatile compounds of bark and leaves, 43.4 and 78.9%, respectively. Ten of 19 selected volatile components elicited significant EAG responses in adult B. horsfieldi, which indicated that the pest may prefer certain volatile compounds when selecting a host. Sex and volatile concentration affected the responses of B. horsfieldi. Male adults had the strongest EAG responses to 1‐octen‐3‐ol, whereas female adults had the strongest EAG responses to linalool. Host selection in B. horsfieldi was somewhat positively associated with the concentrations of the effective volatile compounds in the host. Furthermore, B. horsfieldi showed varying preferences for isomers. This work provided data support for the development of insect attractants, and laid a theoretical foundation for the ecological protection of local forestry.
