  abstract = {{T}he extent of damage to crop plants from pest insects depends on the foraging behaviour of the insect's feeding stage. {L}ittle is known, however, about the genetic and molecular bases of foraging behaviour in phytophagous pest insects. {T}he foraging gene (for), a candidate gene encoding a {PKG}-{I}, has an evolutionarily conserved function in feeding strategies. {U}ntil now, for had never been studied in {L}epidoptera, which includes major pest species. {T}he cereal stem borer {S}esamia nonagrioides is therefore a relevant species within this order with which to study conservation of and polymorphism in the for gene, and its role in foraging - a behavioural trait that is directly associated with plant injuries. {F}ull sequencing of for c{DNA} in {S}. nonagrioides revealed a high degree of conservation with other insect taxa. {A}ctivation of {PKG} by a c{GMP} analogue increased larval foraging activity, measured by how frequently larvae moved between food patches in an actimeter. {W}e found one non-synonymous allelic variation in a natural population that defined two allelic variants. {T}hese variants presented significantly different levels of foraging activity, and the behaviour was positively correlated to gene expression levels. {O}ur results show that for gene function is conserved in this species of {L}epidoptera, and describe an original case of a single nucleotide polymorphism associated with foraging behaviour variation in a pest insect. {B}y illustrating how variation in this single gene can predict phenotype, this work opens new perspectives into the evolutionary context of insect adaptation to plants, as well as pest management.},
