Abstract

Dispensers made of different materials and loaded with the female sex pheromone, (Z)-7-tetradecenal, were field-tested for attractancy for males of Prays citri (Mill.) in Israel. Hollow fibres of low density polyethylene, low density polyethylene chips and natural rubber septa were better than hollow fibres of polypropylene, hollow fibres of a polypropylene-polyethylene mixture, solid fibres of low density polyethylene and PVC tubes. In other tests, funnels with wall angles of 60° were inferior to those with angles between 70 and 80°; polyester funnels were superior to polystyrene and polypropylene ones, which were better than those of PVC or opalin coated with aluminium foil. Kaolin or talcum powder dusted on the inside walls improved the efficiency of polypropylene funnels. The catches in traps consisting of several plastic funnels or tubes under a roof and with insecticide to prevent escape did not differ significantly from those in the sticky traps. A modified version of a new trap with a renewable sticky floor is described; this and the funnel traps are at present the most useful and practical for catching P. citri males.
