Treatment of male larvae in ants of the genusMyrmica

Traitement des larves mâles chez les fourmis du genre Myrmica

Summary

  1. 1.

    Unlike female larvae, male larvae are not attacked by workers under queen influence during spring growth in the third instar.

  2. 2.

    Though they are underfed in these circumstances and mature at a smaller size, than they would if queens were absent, there is no evidence that they die, at least in the third larval instar.

  3. 3.

    It follows that control over male number, but not size, relies on the oogenetic switch from reproductive to trophic, that laying queens and their egg masses effect.

Resume

  1. 1.

    Contrairement aux larves femelles, les larves mâles du troisième stade ne sont pas attaquées par les ouvrières, lorsque les reines sont présentes.

  2. 2.

    Bien qu'elles soient sous-alimentées et qu'elles deviennent moins grosses en présence des reines qu'en l'absence de celles-ci, elles ne montrent pas un taux de mortalité plus élevé.

  3. 3.

    En effet, le facteur responsable du contrôle du nombre de mâles réside dans le contrôle de l'ovogenèse des ouvrières par les reines et leurs œufs.
