Abstract

The average catches of Bactrocera invadens obtained from home-made open-bottom dry traps of mineral water translucent plastic bottles of 1.5 L, 5 L, and "Sentrap" Open-top Dry local Trap (plastic prototype improved by SENCHIM, an agrochemicals industry based in Senegal) were compared to the conventional trap "Multilure" (Better World Manufacturing, Inc.., Miami, FL). Results show that no significant difference was found when "Multilure" was compared to the 5 L plastic bottle trap. The study of the relationships between catches and type of trap was significant for all of them. Sentrap, "Multilure" and 1.5 L bottle trap exhibited a very high significant dependency relationships (r = -0.969**, r = -0.903** and r = -0.801**; respectively and p< 0.01). And the 5 L bottle trap was significant with r = -0.801* and p< 0.05. Thus, in case of absence of conventional traps, the plastic bottle of 5 L could, therefore, be used as an alternative and its basal part painted in yellow should increase its efficiency. Also, due to simple design and less time needed for servicing "Sentrap", increasing its volume and openings and fixing firmly the upper part with a lid screw might improve its efficiency.

Key words: Traps, catches, Bactrocera.
