Interspecific Competition between <i>Anisopteromalus calandrae</i> (Howard) (Pteromalidae) and <i>Dinarmus basalis</i> (Rond.) (Pteromalidae) on <i>Callosobruchus chinensis</i> (L.)

The effects of interspecific competition between parasitoids Anisopteromalus calandrae (Howard) and Dinarmus basalis (Rond.) for their host, Callosobruchus chinensis (L.) have been conducted at a constant temperature of 30±1°C and 75±5% r.h. A number of 40, 80, 120, 160 and 200 4th instar larval host containing seeds of C. chinensis were confined to 24,48,72,96 and 120 hours egg laying of both the parasitoids respectively. Total number of progeny produced by the two parasitoids were 16.9 ± 2.76, 20.7 ± 5.69, 31.1± 7.47, 38.6 ± 5.87 and 56.7 ± 9.86 at 24, 48, 72, 96 and 120 hours duration respectively. The parasitoid, D. basalis showed higher parasitism than A. calandrae in competition of host choice in all the egg laying periods observed. The individual highest parasitism of D. basalis was 50.0, 33.75, 36.66, 30.0 and 32.0 and that of A. calandrae was 25.0, 15.0, 18.33, 16.25 and 21.0 % respectively in 24, 48, 72, 96 and 120 hours duration respectively.

Functional Response of <i>Dinarmus basalis</i> (Rond.) (Hymenoptera: Pteromalidae) Parasitizing <i>Callosobruchus maculatus</i> (F.)

The functional response of the parasitoid Dinarmus basalis (Rond.) (Hymenoptera: Pteromalidae) is determined to evaluate its potential as a biological control agent. Four female wasps in the presence of males parasitoids, were allowed to oviposit during their life span or hosts at different densities. The data were fit by Rogers? (1972) parasitoid model. The rate of parasitoid search was a?= 0.123 ±0.005 life span-1, and handling time Th = 0.056 ± 0.002 life span-1. Volume of grain had no significant (P>0.001) effect on number of parasitoids emerging.
