(Potato), eggplant fruits, <em>Solanum melongena<\/em> L. (Aubergine) and green tomatoes, <em>Solanum esculentum<\/em> Mill (Tomato), to evaluate the preferred host plant for feeding <em>Ph. operculella<\/em> larvae. The calculated biological parameters were: Net reproductive rate of increase (R<sub>0<\/sub>), generation time (G<sub>t<\/sub>), intrinsic rate of increase (<em>r<\/em><sub>m<\/sub>), finite rate of increase (\u03bb) and population doubling time (D<sub>t<\/sub>). Obtained results indicated that potato tubers proved to be the quite favorable for achieving the highest developmental and multiplication rates of <em>Ph. operculella<\/em>, followed by eggplant meanwhile tomato was the least favorable. The natural mortality figures; Apparent Mortality (AM), Real Mortality (RM) and Indispensable Mortality (IM) for larvae reared on potato tubers were 20.73, 17.00 and 13.34%, respectively. Meanwhile, the highest mortality rates were 32.58, 29.00 and 18.36% when larvae were fed on eggplant fruits. It is quite worth to mention out here that potato tubers are considered as the most attractive for feeding and rearing <em>Ph. operculella<\/em> for research purposes followed by egg-plant. Tomato seem to be the least acceptable host plant.<\/p>\n<p><strong>Key words: <\/strong>Host plants, Life tables, Potato tuber moth, <em>Phthorimaea operculella.<\/em><\/p>\n<p>Full paper in English: <a href=\"http:\/\/agri-research-journal.net\/sjar\/wp-content\/uploads\/2019\/09\/v6n3p39.pdf\">PDF<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Gassan Youssef*(1) (1).
