摘要: We measured the effects of oviposition by spittlebug Aphrophora pectoralis on shoot growth and bud production in two willow species, Salix miyabeana sachalinensis. In autumn, adult females A. pectoralis insert their ovipositor into apical region 1-year-old shoots, resulting death most tips within 1 week. Consequently, an increase number dead buds a decrease vegetative shoots was recorded. following spring, current-year greatly increased damaged oviposition. Furthermore, rate both S. miyabeana S. sachalinensis. However, no impact reproductive detected either willow. conclude that compensatory species caused A. pectoralis.
