Abstract:
[Objectives] To develop an artificial
feeding technology for Haptoncus luteolus,
an important pollinator of cotton and annonaceous crops, in order will
facilitate exploiting the pollination services of this species and assess its
vulnerability to transgenic Bt cotton. [Methods] The growth,
development of newly hatched larvae and adult fecundity of H. luteolus reared on artificial feed, rape pollen or luffa flower
were measured and compared. [Results] Survival curves of H. luteolus on these three diets were essentially the same.
Compared to those fed on rape pollen and luffa flower, H. luteolus reared on artificial feed had a shorter larval period
and longer pupal period. The cumulative number of eggs laid over 20 days by
females reared on the artificial feed was higher than that of females reared on
the other two diets. Females reared on artificial feed also maintained higher
fecundity for longer than those reared on the other foods. [Conclusion] With the
exception of higher fecundity, the biological
characteristics of H. luteolus reared
on artificial feed are essentially the same as when these insects are reared on
luffa flower. Using this artificial feed and related artificial breeding
technology could allow the long-term and large-scale feeding H. luteolus under laboratory conditions.
