| dc.description.abstract | n 2008, the invasive tomato red spider mite Tetranychus evansi (Acari: Tetranychidae), a pest of sola-
naceous crops, was identi
fi
ed for the
fi
rst time as the cause of serious damage on tomato (
Solanum
lycopersicum
L.; Solanaceae) crops in Benin. Since then, frequent outbreaks have been observed on
Solanaceae and other leafy vegetables such as purple amaranth (
Amaranthus cruentus
L.; Amaranthaceae)
and bitter leaf (
Vernonia amygdalina
D.; Asteraceae) in all growing areas in southern Benin. The objective
of this study was to evaluate the intensity of damage by this invasive pest and the impact of farmers'
control practices on purple amaranth, African eggplant
(Solanum macrocarpon L.
; Solanaceae) and tomato
crops. A survey was carried out in January 2013 among 150 farmers in the three major growing areas in
southern Benin: S
em
e-Kpodji, Grand-Popo and Pahou.
Tetranychus evansi
was the only mite observed,
causing production losses estimated at 65% for African eggplant, 56% for tomato and 25% for purple
amaranth. Previously encountered species such as
Tetranychus urticae
Koch,
Tetranychus ludeni
Zacher
(Acari: Tetranychidae) and
Polyphagotarsonemus latus
Banks (Acari: Tarsonemidae) were not observed in
any of the 45 samples. To protect the infested crops, growers sprayed various synthetic pesticides at high
frequencies according to crop phenology 3, 6 and 12 times per month, respectively, on purple amaranth,
African eggplant and on tomato, on average. The most frequently used pesticides were pyrethroids and
organophosphate compounds. Farmers reported that these compounds were largely ineffective against
T. evansi
. The risks posed to human and environmental health, as well as existing alternatives to chemical
pesticide use, are discussedn 2008, the invasive tomato red spider mite Tetranychus evansi (Acari: Tetranychidae), a pest of sola-
