Abstract: The potato tuber moth, Phthorimaea operculella, (Zell.), is recognized as the most serious and destructive pest of the potato in the Republic of Yemen. Its larva mine the aerial parts of the potato plant, the subterranean and the stored tuber. Laboratory studies were done at 26±1°C, under natural humidity (45±5%) and with 12h of light and 12h of darkness. Sumithion (Fenitrothion, 40 EC) at the rate of 10 ml/10 l, as a standard insecticide and aqueous extracts of the outer pulp of Melia azedarach L. and Allium sativum L. at the rate of 100g/10l were used for the control of potato tuber moth larvae. Separate batches of 30 third-instar larvae were treated. The control batches were treated with plain water. Mortality was assessed after 24 h and later at daily interval until the emergence of the moth. The applied chemical and natural insecticides were considerably effective. The mortality amounted to: Sumithion =100%, M. azedarach =91.7% and A. sativum =85%. In regard of controlling the potato tuber moth the results show the possibility of killing the pest with help of natural insecticides instead of environment-damaging chemical insecticides in the Republic of Yemen.
