| Abstract | ||
| This present study was conducted, in potato fields at Kalubia region during 1997 and 1998 seasons. Weekly number of Phthorimaea operculella (Zeller) male moths captured in sex pheromone traps were recorded. Results indicate that the most effective level for the sex attractant traps was 40 cm above the end of the height of the plant level, followed by 20 cm for funnel and water plastic traps. Accordingly, the results indicate that the funnel traps, generally, captured more moths than the water plastic traps. In the meantime, the sex pheromone traps were instrumental in detecting and monitoring the first occurrence and population fluctuations of potato tuber moth, thus could be helpful in determining the proper time of insecticides use, and then B.t. insecticide use became necessary. Data also indicate that the weekly means of male moths catch/trap in funnel trap and water trap were 101.42 & 76.57 in 1997 against 77.92 & 64.57 in 1997 and 1998 seasons, respectively. So, it is useful to use the funnel trap more than yellow water trap. That's for funnel trap is cheaper and its way of catching is easier. | ||
