What do nun moths do?
The nun moth is the most serious defoliating insect pest of the Scots pine, Norway spruce and some other tree species. One caterpillar can damage about 300 Scots pine needles or 1000 Norway spruce needles during its development. The spruce tree defoliated more than 50% usually dies.
Why are nun Moths invasive?
Its establishment in North America would be disastrous because of its polyphagous feeding habits, ability to colonize new habitats, and capacity to be spread rapidly by vagile adults. Adults are readily attracted to artificial lights and have been observed in Russian Far East ports.
What eats nun moths?
Many natural enemies have been recorded attacking nun moth, usually during outbreaks or in the decline phase as populations collapse. These include many species of parasitoids (mostly tachinid and sarcophagid flies and braconid wasps).

How can we control invasive species?
Chemical control includes the use of pesticides, herbicides, fungicides, and insecticides. Cultural control includes manipulation of habits to increase mortality of invasives or reduce it’s its rate of damage (selection of pest-resistant crops, winter cover crops, changing planting dates).
How do you control invasive species of animals?
10 Ways You Can Prevent the Spread of Invasive Species

What is biological control of invasive species?
Biocontrol, short for biological control, is the management of a pest, typically invasive species, by introducing a natural predator into the environment. Biocontrol reduces the pest population and their impacts on the environment.
Is Lymantria monacha a tree species?

When did the outbreak of Lymantria monacha occur in Poland?
Occurrence and control of important foliophages in Scots pine [Pinus sylvestris] stands in 1946-85. Sylwan, 131 (11-12):49-59 Sliwa E, Sierpinski Z, 1986. Outbreak of Lymantria monacha in Poland from 1978 to 1984. Anzeiger fur Schadlingskunde, Pflanzenschutz, Umweltschutz, 59 (5):81-86 Steinfatt O, 1942.
Is it monacha or Lymantria minomonis okinawaensis?
Lymantria minomonis okinawaensis found on Okinawa and Lymantria minomonis sugii in Taiwan have previously been misidentified as L. monacha because they look like the lighter form ( Kishida, 1987 ).
What does a Lymantria larva look like?
The larvae of Lymantria species have a full complement of low, rounded verrucae, without dense hair tufts, and usually without hair pencils. The dorsal verrucae bear needle-like setae and sometimes longer hairs. Newly hatched larvae are approximately 4 mm long. At first, they appear tan-coloured but within several hours they turn black.
