【 摘 要 】

Thyrinteina arnobia, is one of the most important defoliating caterpillars of Eucalyptus in Brazil The objective of this work was to evaluate the development and the reproduction of feeding on leaves of guava (Psidium guajava) or Eucalyptus grandis in the 15th generation, after rearing this species for 14 genrations on guava leaves. T. arnobia showed shorter larval period, better viability of caterpillars and pupae, heavier pupae, higher number of eggs per female, better egg viability and shorter longevity of females in guava leaves than in Eucalyptus leaves. The better development and reproduction with P. guajava showed that this insect could be reared in laboratory with guava leaves.
