Six individual different terpenes these are: (\u00b1)-menthol, B-citronellol, (\u2009+\u2009)-3-carene, (R)- (\u2009+\u2009)- limonene, citronella oil and orange terpenes. The results revealed significant differences between the terpenes used on the olfactory response on this insect, in that half of the compounds were very attractive while the other half were repellant to them. This behavior study results with olfactometer citronella oil exhibited an 80% attraction response rate for both sexes, while menthol exhibited a 60% attraction response rate for females and 100% for males. By contrast, menthol had a more significant effect on adults than citronella, lethal concentration at 50 scale (LC\n                    <jats:sub>50<\/jats:sub>\n                    ) values of 1.03, 0.89, and 0.9\u2005mg, and LC\n                    <jats:sub>95<\/jats:sub>\n                    values of 5.09, 2.01, and 1.59\u2005mg, after 24, 48 and 72\u2005h, respectively. For citronella oil, the LC\n                    <jats:sub>50<\/jats:sub>\n                    values were 2.09, 1.76, and 1.70\u2005mg after 24, 48, and 72\u2005h, and the LC\n                    <jats:sub>95<\/jats:sub>\n                    values were 5.5, 3.7, and 1.5\u2005mg after 24, 48 and 72h, were noted. In the present study, the effects of citronella and methanol insecticides were observed on six types of hemocytes namely prohemocytes, granulocytes, plasmatocytes, oenocytes, coagulocytes and spherulocytes. Both citronella oil and menthol had a histopathological effect on the hemocytes of the adult red palm weevil, specifically, on the cell membrane, cytoplasm, and nucleus. The findings also revealed that the vacuoles in some hemocytes, specifically, the prohemocytes, plasmatocytes, and granulocytes were more sensitive than those in other hemocytes, which remained unaffected by the treatment.\n                  <\/jats:p>\n                  <jats:p>The effects of citronella and menthol on RPW immunity were demonstrated in this study, and this information may be
