Efficacy of Different Rates of Sexual Pheromoneof Phthorimaea operculella (Zeller) (Lepidoptera: Gellechiidae) in Maleso of PotatoTuber Moth Captures

Potato tuber moth (PTM), Phthorimaea operculella (Zeller), widely world distributed, is one of the most serious insect pest attacking potatoes (Solanum tuberosum L.). Larvae develop in foliage and tubers of potato causing direct losses of edible product. Chemicals treatment to control this pest have...
