Abstract
The fecundity, longevity and daily ovipositional rate of B. stenostigma in H. postica larvae were determined at constant 21.1°C and fluctuating 6.7°/18.3°C temperatures, while a 12:12 h photophase:scotophase was maintained under both regimes. Avg fecundities were not significantly different ( P >0.10) under the 2 temperature regimes. The higher daily ovipositional rate at 21.1°C, as compared with 6.7°/18.3°C, was offset by significantly greater ( P <0.05) longevity at 6.7°/18.3/C; hence, the similar fecundities. The dispersion pattern of the eggs among host larvae under both temperature regimes conformed to the Poisson, or random, distribution in more than 80% of the 195 data sets analyzed. Both the fecundity and ovipositional rate of B. stenostigma are lower than those reported earlier for B. anurus ; the fecundity of B. stenostigma is comparable to that reported for B. curculionis , but the daily ovipositional rate of the latter is greater.
