Abstract

The attraction of Tropinota squalida adults to coloured plastic wa­ter traps in the newly reclaimed area of Nubaria was studied during 1988 and 1989. Results obatined revealed that the adults were attracted in relia­ble numbres to blue, white , yellow and green coloured traps . Few num­bers of adults were attracted to red ones. The mass trapping trials showed that a trap density of 90 blue plastic bassins / feddan captured the highest number of adults . This procedure seemed to be promising in mass trapping the adults of I. squalida in apple orchard.
