Abstract

The effectiveness of the phytoseiid predator Neoseiulus fallacis in controlling population growth of the spruce spider mite, Oligonychus ununguis was examined in the laboratory. Development and fecundity of N. fallacis under various relative humidity levels were also studied. Under controlled conditions, N. fallacis significantly limited population growth of O. ununguis on Fraser fir seedlings. Survival, development, and fecundity of N. fallacis were similar for all relative humidity ranges tested, except at the lowest range (60–65%), in which none of the individuals survived to maturity.

Résumé

L'efficacité du prédateur phytoseiide Neoseiulus fallacis à régler la croissance de population du tétranyque de l'épinette, Oligonychus ununguis a été étudiée au laboratoire. Le développement et la fécondité de N. fallacis à différents niveaux d'humidité relative ont aussi été étudiés. En conditions contrôlées, N. fallacis a significativement limité la croissance de population de O. ununguis sur des pousses de Abies fraseri (Pursh) Poir. La survie, le développement et la fécondité de N. fallacis étaient semblables pour toutes les classes d'H.R. testées, excepté la classe la plus basse (60–65%) pour laquelle aucun individu n'a survécu jusqu'à maturité.
