Therefore, this study aimed to describe these structures in detail, which could provide insights into potential control methods. Ten individuals were collected and histologically processed, with observations made using stereo, light and electron microscopies. The alimentary canal is divided into three sections: the foregut, midgut and hindgut. The foregut comprises the pharynx, oesophagus, crop and proventriculus. A gastric caeca pair lies at the proximal anterior end of the midgut. The midgut is the longest portion. The Malpighian tubules, whose proximal ends open into the midgut and hindgut, have distal ends that connect to the colon wall. The hindgut is further subdivided into the ileum, colon and rectum. The rectum, the final segment of the alimentary canal, has a thick muscular wall and a more pronounced intima layer than the other hindgut regions. Cross sectional SEM images show six rectal pads where the final absorption of nutrients occurs. These findings may lead to new strategies for controlling this agricultural pest.

The Lactin-2 non-linear model was considered best, as it estimated thermal thresholds (<i>T</i><sub>min</sub>, <i>T</i><sub>max</sub> and <i>T</i><sub>opt</sub>) similar to those of the observed values. Analytis model also computed the accurate estimations of <i>T</i><sub>max</sub> and <i>T</i><sub>opt</sub>, but failed to compute the correct estimations of <i>T</i><sub>min</sub>. In a nutshell, Ikemoto and Takai and Lactin-2 are useful and effective models for describing temperature-dependent development and estimating the temperature thresholds of male and female pupae of <i>C. partellus</i>.</p>\u0000 </div>","PeriodicalId":50945,"journal":{"name":"Acta Zoologica","volume":"107 2","pages":"243-254"},"PeriodicalIF":1.3,"publicationDate":"2026-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147568808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
