Cotesia ruficrus (Hal.) took a period of 16.1 days from oviposition to adult emergence. Oviposition to larval egression took 1 ].9 days and pupal period for 4.1 days. Adults survived for 12.26 (females) and 8.1 (males) days with food. Without food they did not thrive beyond 2.2 days. Sex-ratio with male dominance was 1.0: 1.4 (F: M).
