Three strains of Spalangia drosophilae Ashmead, ectoparasitic on Hippelates collusor (Townsend) pupae, from California, Jamaica, and Puerto Rico, are compared for fecundity, longevity, minimum survival temperatures, and ability to reproduce as host densities increase. The California strain demonstrated greatest cold tolerance and highest capability to increase progeny production at high host densities. The Jamaica strain had the greatest fecundity and longevity. Each of the 3 strains showed a… 
DISTRIBUTION PATTERN OF HOSTS AND PARASITIZATION BY SPALANGIA DROSOPHILAE (HYMENOPTERA: PTEROMALIDAE)
TLDR
It was concluded that maximum host destruction resulted when completely random behavior was involved and host destruction was, nevertheless, greater in an all-clumped distribution, with the greater acceptance of clumped groups resulting in a greater number of progeny.
Variation du potentiel biotique de l'auxiliaire parasite Encarsia formosa G. (Hym., Aphelinidae) en fonction du stockage au froid 2. Du point de vue de la fecondite journaliere et de la longevite
TLDR
The study shows that, on the one hand, minor variations in biotic potentialities exist due to differences in, for example, photoperiod, but that on the other hand, the stress due to the cold storage removes this variation.

TLDR
Host destruction wrought by host-feeding and parasitization was often proportionally greater than progeny production at the lower depth, indicating that parasites searched there without finding conditions suitable for oviposition.
