Abstract

Hay bales from areas of high skipper densities contained an estimated 5000 viable eggs/bale underlining the importance of passive transport of Thymelicus lineola (Ochs.) eggs in hay as a means of dispersal for this insect pest. While eggs ingested by cows did not survive it is believed that, in view of the number present in each bale, some would not be eaten and could be the source for a new infestation.

Résumé

Les oeufs de Thymelicus lineola (Ochs.) présents dans les balles de foin provenant de régions fortement infestées ont été estimés à 5,000 oeufs viables/balle, qui montre clairement l’importance du transport passif des oeufs de l’hespérie des graminées dans le foin. De la quantité relativement élevée des oeufs dans les balles de foin, un certain nombre est mangé par les vaches et ne survit pas; les autres deviennent donc une source potentielle d’infestation.
