Ballal, C. R. and Pradyumn Kumar (1989). Performance specifications of an introduced parasitoid, Allorhog aspyralophagus (marsh) on different laboratory hosts. Entomon 1989 Vol. 14 No. 1 & 2 pp. 63 to 66.

The performance of a Mexican parasitoid, Allorhogas pyralophagus (Marsh) (Hymenopera : Braconidae) was studied in the laboratory on five different host insects. The percent parasitism obtained on three pyralids, Chilo partellus (Swinh), C. auricilius (Dudg.) and a noctuid Sesamia inferens (Wlk.) were statistically similar while significant reduction in percent parasitism was observed on Corcyra cephalonica (Staint.) (Lepidoptera: Galleridae). Among the four well preferred hosts, C. partellus was observed to be most suitable for rearing A.pyralophagus, as developmental time of the parasitoid was minimum and longevity and fecundity were maximum when reared on this host insect.
