Pine Processionary - Natural Controls

Natural Controls

The Pine Processionary is an economic pest in coniferous forests in southern Europe. It is controlled to some extent by predators, parasites and viruses which attack the moth at different stages of its life-cycle:

  • Eggs may be eaten by the orthopteran Ephippiger ephippiger.
  • Larvae may be eaten by birds such as Great Tit (Parus major) and Great Spotted Cuckoo (Clamator glandarius).
  • Larvae may be parasitised by solitary wasps (Ichneumonidae, Braconidae) and some species of horse-fly (Tachinidae).
  • Pupae may be eaten by Hoopoes (Upupa epops).
  • Adults may be eaten by bats.
  • Larvae may be infected by the processionary moth virus Smithiavirus pityocampae.

Famous quotes containing the words natural and/or controls:

    I wish more and more that health were studied half as much as disease is. Why, with all the endowment of research against cancer is no study made of those who are free from cancer? Why not inquire what foods they eat, what habits of body and mind they cultivate? And why never study animals in health and natural surroundings? why always sickened and in an environment of strangeness and artificiality?
    Sarah N. Cleghorn (1976–1959)

    The confusion of emotions with behavior causes no end of unnecessary trouble to both adults and children. Behavior can be commanded; emotions can’t. An adult can put controls on a child’s behavior—at least part of the time—but how do you put controls on what a child feels? An adult can impose controls on his own behavior—if he’s grown up—but how does he order what he feels?
    Leontine Young (20th century)
