Halys dentatus is well known sap sucker living under the bark and having the reputation of affecting nutritional supply oftheir host plants. Dichlorovos (2,2-dichlorovinyl dimethyl phosphate) is an organo-phosphorus compound previouslyused for controlling crawling and flying insect pests. In the present study dichlorovos has been tested as systemic poison for checking its lethalityagainst plant bug Halys dentatus. The oral application has found to be effective, as it disintegrates components of gastro-intestinal tract affectingvitality of test individuals. The adult plant bug when treated with dichlorovos, alteration in histological structures of ventriculus has beenobserved. In most of the cases alteration in shape of ventricular components has been noticed; basement membrane has found to be collapse whilelongitudinal and circular muscles layers were also disrupted. The cell boundaries of epithelial cells found to be busted and secretory cells becomedenatured; nuclei were found to be stained intensely as compared with untreated histological sections
