Effect of accumulative temperatures on the development of tuber moth Phthorimaea operculella Zeller


, : Effect of accumulative temperatures on the development of tuber moth Phthorimaea operculella Zeller. Journal of Biological Sciences Research, Iraq 15(2): 1-11

In laboratory rearing of the potato pest Phthorimaea operculella in Iraq, the thermal development threshold was calculated to be 10 degrees C. An average of 437.8 effective day-degrees C was found to be required for the appearance of peak populations causing severe economic damage to potato.
