Efficiency of traps for Stomoxys calcitrans and Stomoxys niger niger on Reunion Island

Abstract

The main objective of this study was to compare the trapping efficiency of two Alsynite sticky traps (modified Williams and modified Broce) and two phtalogen blue cloth traps (Vavoua and Nzi) to be used in an integrated control programme of Stomoxys spp. (Diptera: Muscidae) on Reunion Island. Mean daily catches of these flies on two dairy farms differed significantly between the four types of trap. The Broce trap was the least efficient and had the lowest specificity for Stomoxys spp. The Vavoua, Nzi and Williams traps performed significantly better but could not be ranked on the basis of the numbers of Stomoxys caught because their respective performances differed between farms. Given the various practical criteria, it is concluded that, as control tools, blue cloth traps (Vavoua and Nzi) have practical advantages over the Williams trap. The Vavoua trap, which is less expensive and easier to use for farmers, seems adequate to complement other methods of fly control on Reunion Island.

“…Cependant, les faibles captures enregistrées pourraient s'expliquer par l'utilisation de ces deux types de piège. En effet, bien que l'efficacité de ces pièges pour la capture des stomoxes, tabanidés et glossines soit avérée (Djiteye, 1992 ;Djiteye 1994 ;Mihok et al, 1995b ;Mihok, 2002 ;Gilles 2005 ;Gilles et al, 2007 ;Mavoungou et al, 2012), l'association de plusieurs types de piège (Nzi, grand Tetra, petit Tetra, Vavoua) et l'adjonction d'attractifs olfactifs comme l'octénol seul (Jaenson, 1991 ;Mihok et al, 1995b) ou en association avec des phénols (Mihok et al, 1995b) auraient peut-être permis d'augmenter les captures (Djiteye, 1992 ;Amsler and Fillerdier, 1994).…”

A longitudinal study of Besnoitia besnoiti infections and seasonal abundance of Stomoxys calcitrans in a dairy cattle farm of southwest France

“…The six locations of Vavoua traps were chosen to cover all grazing pastures around the cowshed and to be as close as possible to the dairy herd. The distances between different traps were at least 50 m to avoid competition between traps (Gilles et al, 2007). Captured insects were killed by freezing at −70 • C, identified and counted trap by trap.…”

“…According to Gilles et al (2007), the Vavoua trap was used to monitor the dynamics of blood feeding insects including stable flies and Tabanids. Six Vavoua traps were installed at 8:30 a.m. and were removed at 6:00 p.m. once a month, between May 2008 and May 2009.…”

“…Others non-hematophagous flies including horse fl ies (Tabanidae) 9 and stable fl ies (Muscidae: Stomoxyinae) 10 . The trap was placed within one of the camel farms located in the affected area, and was maintained for 12 months (July, 2010 through June, 2011).…”
