Brownheaded leafrollers - Fecundity

The number of eggs produced by brownheaded leafrollers is highly variable.

Average fecundity in the laboratory (freeze-dried apple leaves)   58 - 429 eggs/female
Average fecundity in the laboratory (artificial diet)   739 eggs/female
Range of fecundity (apple leaves)   not available*
Range of fecundity (artificial diet)   200 - 1223 eggs/female

Variation in fecundity is determined primarily by weather conditions, and probably the quality and succession of host plants. *Brownheaded leafroller females which had been fed freeze-dried apple leaves as larvae produced an average of 193-429 eggs at 11.5oC, an average of 58-143 eggs at 18oC , and an average of 69-182 eggs at 22.5oC.
