Evaluation of the Efficiency of Probe and Indicator Device traps for Catch Adults of the Cowpea weevil Callosobruchus maculatus Fab. (Coleoptera: Chrysomeloidea)

Abstract

The Probe trap was tested with three types (empty, water, alcoholic extract of (Vicia faba) respectively and for three periods of time (1, 2, 3) days respectively to catch the cowpea weevil C. maculatus that infests the broad bean seeds prepared for cultivation. It gave a trap Probe catching percentage on the third day of placing the traps respectively (19.16, 62.5, 88.33)% respectively, and the lowest catching percentage on the first day was (5.83, 20, 41.67%) respectively, while the highest percentage of catch was for the Indicator device trap with three species (Grease as sticky material , water, Vicia faba flower extract) for the third day with placing traps (52.5, 70, 72.5%) respectively, and the lowest percentage of catching was on the first day, which was (27.5, 40, 47.5%) respectively. From the experiment, the efficiency of the Probe trap and the Indicator device trap, to which bean flower extract was added, in hunting C. maculatus adults for the same time period, where the extract increased the efficiency of the two traps, followed by water for the same period of time.
