Summary
A cytogenetic study was performed on 2 waps species of the tribe polistini, including the determination of chromosome number and the detection of thterochromatin by C-banding technique.Polistes (Epicnemius) cinerascens presents n=27, 2n=54 chromosomes of the meta- sub- and acrocentric types; heterochromatin has a varied distribution: in and around the centromere in chromosomes: sometimes on one of the majority of the arms or on almost throughout the entire chromosomes.Poliste (Aphanilopterus) versicolor versicolor presents n=31, 2n=62 meta- and submetacentric chromosomes; heterochromatin is distributed on one of the chromosome arms.
Resume
Une étude cytogénétique a été développée chez deux espèces de guêpes de la tribu Polistini comprenant la détermination du nombre de chromosomes et aussi la détection de l'hétérochromatine par l'emploi de la technique de la bande C.Polister (Epicnemius) cinerascens possède n=27, 2n=54, comprenant des chromosomes des types meta- subet acrocentriques; l'heterochromatine a une localisation diverisifiée: dans le centromére au long du chrosmosome.Polistes (Aphanilopterus) versicolor versicolor possède n=31, soit 2n=62 chromosomes des type meta-et submétacentriques; l'hétérochromatine et distribuée sur l'un des bras du chromosome.
