Summary
The chromosome number and karyotype of two wasp species of the genusPolistes were determined by a technique involving colchicine and sodium citrate pre-treatment, which permitted a more precise chromosome identification. The speciesPolistes (Aphanilopterus) simillimus, with n=28, 2n=56 chromosomes, andPolistes (Aphanilopterus) versicolor versicolor, with n=31, 2n=62 chromosomes, showed sharply characteristic individual karyotypes.
Resume
Le nombre de chromosomes et le caryotype de deux espèces de guêpes du genrePolistes ont été déterminés. Il a été développé une technique comprenant le traitement préalable à la colchicine et au citrate de sodium, lequel permet une identification plus précise des chromosomes. Les espècesPolistes (Aphanilopterus) simillimus avec n=28, 2n=56 chromosomes etPolistes (Aphanilopterus) versicolor versicolor avec n=31, 2n=62 chromosomes ont montré des caryotypes bien caractéristiques.
