Comparative efficacy of different traps in Attracting males of fruit fly, Bactrocera invadens

The average catches of Bactrocera invadens obtained from home-made open-bottom dry traps of mineral water translucent plastic bottles of 1.5 liters and 5 liters, 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 showed that no significant difference was found when “Multilure” was compared to the 5-liters plastic bottle trap. In the relationship between catches at different periods and type of trap, the coefficient of correlation was significant (P <0.05) for all traps. In the absence of conventional traps, the plastic bottle of 5 liters could, therefore, be used as an alternative. 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. This trap can also be manufactured at an affordable price for different categories of fruit producers.
