New foci of Rhipicephalus microplus in West Africa
The invasive character of Rhipicephalus microplus was observed in Benin, the
second West-African country from which this ticks species has been collected after the
initial confirmed record in Ivory Coast in 2007. A cross-sectional study was carried out in
the Department of Mono to examine the presence of the tick R. microplus. The survey
covered 9 herds (villages) in an agro-ecological zone inhabited by agro-pastoralists,
including the State Farm of Kpinnou that imported Girolando cattle from Brazil. Almost
800 ticks were sampled from 36 cattle, on average four cattle per village. The morphological
identification revealed ticks of two different genera: Rhipicephalus and Amblyomma.
Rhipicephalus microplus was the only representative of the species previously
known as Boophilus or blue ticks. Its taxonomic identity was confirmed molecularly by
PCR–RFLP. A comparison was made with the situation of R. microplus in Brazil.The Belgian Development Cooperation (BDC) for the

West African Cattle Farmers’ Perception of Tick-Borne Diseases
Worldwide, cattle production is struggling to face the negative impacts caused by ticks and Rhipicephalus (Boophilus) microplus is one of the most harmful ticks for livestock. Most of the people in West Africa depend on cattle farming and subsistence agriculture. The presence of ticks on cattle is a major problem faced by smallholder farmers who fight for their livelihood. National and regional tick control programs could assist these rural communities in protecting their livelihoods against ticks and tick-borne diseases, but only if they take into account the targeted herders and their perception on cattle management and tick control. This paper aims to provide a better insight in the socio-economic characteristics of Beninese cattle farmers, and their perception on tick burden, as well as to document common tick control strategies. Different tick species and their seasonality are well understood by cattle herders. For tick control, many still use manual tick removal, especially in the north of the country. The high cost of acaricides, the lack of financial means of African farmers, and of the local stockbreeders in particular, limits the use of acaricides in livestock breeding in Benin. While aiming to increase the meat or milk production of their animals, stockbreeders who can afford it sometimes turn to an abusive use of acaricides, which might in time lead to an increase in tick resistance. This study remains one of the rare studies to report extensively on the perceptions of West African cattle herders

GROWTH PERFORMANCE UNTIL WEANING OF YOUNG RABBITS BORN IN FRANCE AND FOSTERED IN BENIN AT 3 DAYS OF AGE, IN COMPARISON WITH LOCAL RABBITS
[EN] A total of 80 two-day-old suckling rabbits of a selected
New Zealand White rabbit strain imported from a temperate country
(France) were suckled in a tropical country (Benin) by foster does of the
local population. The growth performance of the imported rabbits and of
81 native rabbits suckled by the same does was compared. No
morbidity was observed in both groups. Growth rate was identical in
both groups up to 21 days i.e. the end of the exclusive milk feeding : 10.2 and 10.5 g/day for imported and native rabbits respectively. During
the last period befare weaning (21 to 31 days) the group of imported
sucklings had a lower growth rate (13.0 vs 17.1 g/day). This period
corresponds to the beginning of salid food consumption. A genetic
adaptation of the local rabbits to the local feed and/or climate, or, more
probably, an effect of the early chemosensory experience (during both
gestation and first suckling) of the imported strain are discussed.[FR] Un total de 80 lapereaux de 2 jours provenant d'une souche de lapins
Néo Zélandais Blancs sélectionnée dans un pays tempéré (France), ont
été transportés et adoptés dans un pays a climat tropical (Bénin) par
des méres d'une population locale. La croissance des lapereaux
importés et des lapereaux autochtones a été comparée. Aucune
morbidité particuliére n'a été observée dans aucun des deux groupes.
La croissance fut identique pour les deux groupes jusqu'a l'age de 21
jours, soit jusqu'a la fin de l'alimentation exclusivement lactée des lapereaux : 10,2 et 10,5 g/jour pour les lapereaux importés et locaux
respectivement. Entre 21 et 31 jours (sevrage) les lapereaux importés
ont eu une croissance plus faible : 13,0 centre 17, 1 g~our pour les
lapereaux nés sur place. Cette période correspond au début normal de
la consommation d'aliment solide. Deux hypothéses explicatives sont
évoquées par les auteurs : soit une adaptation génétique de la souche
locale a l'alimentation locale eUou au climat, soit plus probablement une
différence entre les lapereaux importés et les lapereaux locaux dans
