Abstract

The tubercles present on the egg chorion of the carrot weevil, Listronotus oregonensis (LeConte), are described and their variability in density quantified between females. Tubercle density varied by a factor of six between females, from 19 000 to 115 000 tubercles per mm2. The average density of tubercles for a given female remained constant throughout its oviposition period. When isofemale lines were created, the average tubercle density remained constant from generation to generation, and crossing experiment suggested that tubercle density was transmitted by the female. Using isofemale lines with low and high densities of tubercles, no effect on egg survival in water or susceptibility to egg parasitism was found. Tubercle density and the heritability of this character suggest a probable reproductive advantage for females that produce eggs with this chorionic pattern even though the precise role of these traits remains to be determined.

Résumé

Les tubercules présents sur le chorion de l'oeuf du charançon de la carotte, Listronotus oregonensis (LeConte), sont décrits ainsi que la variabilité en densité de ces tubercules entre les femelles. La densité des tubercules varie par un facteur de six entre les femelles, passant de 19 000 à 115 000 tubercules par mm2. La densité moyenne des tubercules reste cependant constante pour une femelle donnée tout au long de sa période de ponte. Lorsque des lignées isofemelles ont été crées, le nombre moyen de tubercules est resté constant d'une génération à l'autre et des expériences de croisement suggèrent que la densité des tubercules est transmise par la femelle. En comparant des lignées isofemelles avec de basse et de haute densités de tubercules, aucun effet de l'immersion dans l'eau ou de susceptibilité au parasitisme n'a pu être démontré. Le haut niveau de variabilité observé et l'héritabilité de ce caractère suggèrent que les femelles produisant des oeufs avec une densité élevée de tubercules ont un avantage reproductif sous certaines circonstances.
