Abstract

Patasson lameerei Debauche development from egg to adult emergence onSitona hispidulus (Fabricius) eggs at 7.2, 10.0, 15.6, 21.1 and 26.7°C required 154.1, 75.4, 24.3, 17.6, and 12.9 days for females and 147.3, 61.0, 23.4, 15.4, and 11.6 for males, respectively. At 21.1°C the optimal age ofS. hispidulus eggs for parasitism byP. lameerei was 2 days, with effective parasitism occurring on eggs ranging from 1 to 4 days old.

Résumé

Le développement dePatasson lameerei Debauche de l'œuf à l'émergence de l'adulte sur des œufs deSitona hispidulus (F.) à 7,2, 10,0, 15,6, 21,1 et 26,7°C a nécessité 154,1, 75,4, 24,3, 17,6 et 12,9 j pour les femelles et 147,3, 61,0, 23,4, 15,4 et 11,6 j pour les mâles, respectivement. A 21,1°C, l'âge optimal des œufs deS. hispidulus pour le parasitisme deP. lameerei a été de 2 j, un parasitisme effectif ayant lieu sur des œufs âgés de 1 à 4 j.
