METHOD: Life Cycle CONDITIONS: Lab - 16h light at 21-28C METHOD NARR: CPB's were raised and egg masses were collected. Eggs from each parent were divided and placed on tbr and ber. Larvae were grown and assessed for development emerged as adults they were fed with the same species. Fecundity was measured as total number of eggs produced during first 15 days of adult life. Developmental time and survival for each instar and the pupal stage were restical differences were found in the developmental time of all stages of beetles grown on ber compared with tbr. Survival rates were lower on ber than tbr except for the pupal stage. Fecundity was higher and preoviposition timr. A variety of analyses were performed to determine variance according to sex, sire, dam, host and combinations thereof. AUTHOR EXPLANATION: Results indicate that a portion of the CPB population could utilize ber. However, the dimeters were not equally effected by the plant species. Survival and fecundity were reduced and more variable on ber than tbr, but development time, prepupal weight, and egg weight varied less between plant species.
