Growth curves were studied for the egg, larva, and pupa of the secondary screwworm, Cochliomyia macellaria (F.), under mean cyclic temperatures of 15.6,21.1,26.7,32.2, and a constant 25 0°C. Development from egg to adult under all regimes ranged from 170 to 588 h. A constant temperature regime of 25°C produced a range of pupation times from 92 to 142 h, with adult emergence ranging from 196 to 261 h. The maximal preferential temperature of 39°C was determined for maggots by using a gradient system.
The minimal variation in the range of larval lengths and development time makes this species suitable for establishing relatively narrow confidence intervals when constructing a postmortem interval estimate for use in legal investigations.
