  abstract = {{T}he cotton aphid ({A}phis gossypii), is a polyphagous species that transmits phytoviruses. {I}t is one of the most damaging and widespread insect pests in pomegranate orchards worldwide, including countries of the {M}editerranean basin such as {A}lgeria. {T}he control of its populations mainly relies on synthetic pesticides although safer alternatives, such as botanical insecticides, warrant further exploration. {T}his study investigated the aphicidal potential of the essential oil ({EO}) of {S}antolina africana leaves ({A}steraceae), widespread {N}orth {A}frican shrub, against {A}. gossypii populations under laboratory conditions. {T}he {EO} phytochemical profile was determined by {GC}/{MS}. {T}he 49 compounds identified were mainly oxygenated sesquiterpenes and monoterpenes, with artemisia ketone (22.69%) and longiverbenone (16.55%) as the dominant compounds. {T}he toxicity of the {EO} was tested at five concentrations (0.1-1.6%, v/v) through topical contact and fumigation bioassays across seven exposure times (2-72 h). {E}ach bioassay involved a population of 25 aphids with five replicates, totalling 750 individuals per method. {M}ortality was both concentration- and time-dependent, reaching 100% within 12 h under fumigation. {A}fter 24 h, fumigation required {EO} concentrations 3.6 and 36 times lower than topical application to achieve {LC}50 and {LC}90 values, respectively. {T}his study provides the first evidence of the strong biocidal activity of {S}. africana leaf {EO} against {A}. gossypii populations, highlighting its potential for pest populations and for reducing the spread of the phytoviruses transmitted by this aphid.},
