  abstract = {{L}_objectif de ce travail est d_{\'e}tudier l_infl uence des temp{\'e}ratures hivernales sur la survie des {B}. tabaci adultes. {L}es individus sont soumis {\`a} un cycle de temp{\'e}ratures qui correspond aux temp{\'e}ratures observ{\'e}es pendant les 24 heures d_une des journ{\'e}es les plus froides de l_hiver du sud de la {F}rance ({P}erpignan). {L}_{\'e}volution de ces temp{\'e}ratures est reproduite en conditions contr{\^o}l{\'e}es, et les individus sont expos{\'e}s {\`a} un, trois ou quatre de ces cycles. {A}pr{\`e}s un cycle de 24 heures, le taux de survie moyen des individus est de 73,5% alors que celui du lot t{\'e}moin est de 85%. {A}pr{\`e}s une exposition {\`a} 3 cycles, le taux moyen de survie reste encore relativement {\'e}lev{\'e} (44,4%). {L}es chances de survivre {\`a} 4 cycles de 24 heures est de 7,4%. {L}e {N}ord m{\'e}diterran{\'e}en semble {\^e}tre une zone tampon pour le maintien en ext{\'e}rieur des populations de {B}. tabaci car ni les temp{\'e}ratures minimales r{\'e}guli{\`e}rement enregistr{\'e}es, ni leur dur{\'e}e, ne sont clairement limitantes.  {S}urvival of {B}emisia tabaci ({H}omoptera: {A}leyrodidae) on the winter conditions of the north zone {M}editerranean {S}ea. {T}he aim of this job was to study the influence of the winter temperatures on the survival of {B}. tabaci adults. {T}he individuals are subjected to a cycle of temperatures which corresponds to temperatures noticed during 24 hours by one of the most cold days of the winter of the south of {F}rance ({P}erpignan). {T}he evolution of these temperatures is reproduced in controlled conditions, and the individuals were subjected to one, three or four of these cycles. {A}fter a cycle of 24 hours, the rate of survival of the individuals is 73,5 % while that of the control is 85%. {A}fter an exposure of 3 cycles, the rate of survival remained high (44,4 %). {T}he probability to survive to 4 cycles of 24 hours is 7,4 %. {T}he {M}editerranean {N}orth seems to be a buffer zone for the establishment of the populations of {B}. tabaci because neither the regularly recorded minimal temperatures nor their length seem to be limiting factors.},
