The boxwood tree moth has caused severe damage to this popular tree / hedging since it was first find in Europe in 2007 . Capsanem , an effective environmentally sustainable result based on entomopathogenic nematodes , has rise to control this destructive cat which has left a lead of destruction through timberland , parks , tree nurseries and garden in France , Germany , the Netherlands , Switzerland , Austria and the United Kingdom these retiring few years .
Lab and field trial have proven that Capsanem , containing Steinernema carpocapsae nematodes , can effectively see the Box tree moth which attacks the coarse box tree ( Buxus sempervirens ) as well as Buxus microphylla , Buxus sinica and Buxus colchica . The first sighting of the moth from the Crambidae family , a native to South - East Asia , was made in Germany in 2007 .
‘ In the past we could only place traps and monitor the boxful tree moth by using pheromones , but we now have a new curative method to control them , in addition to Bt based products or mat commotion and Trichogrammas ( which are only usable in a few countries ) ’ , say Koppert Product Manager Cyrille Verdun . Several cities in France are already using nematode against this pests , and with succeeder . Most of the time they are used as a complementary root to Bts which are often difficult to handle in public space due to their position as crop protection products .
Box tree diagram Caterpillar can develop in large routine and in hard cases kill box tree works . The caterpillars will defoliate flora and will skeleton like leaves with net that can treat the entire Sir Herbert Beerbohm Tree . They can even bore into the barque of more mature box flora . Box tree caterpillars are green with classifiable black stripes and white superman .
Control methodsAs a preventative measure , the cocoons of hibernating larvae need to be key out and absent from November to March . It is then important to detect the other signs of an attack in spring . The first step is to place boxful tree moth trap ( Buxatrap ) , pheromone traps take the sex pheromone Pherodis Cydalima perspectalis , to lure the moth . This pull in the male moths to the traps . Not the females that lay egg and spread out the plague . The second footmark is to use Capsanem ( entomopathogenic roundworm ) to control the larvae of the box tree moth . Evening sprays of these predatory nematodes are recommend .
Pherodis Cydalima perspectalis
roundworm provide solutionAlthough Koppert Biological Systems has been rearing nematode worm since the 80 ’s , they have principally been used in soil software against ground pests , like thrip larvae or vine weevil larvae . More latterly Koppert ’s R&D Department has carried out extensive inquiry into nematode with specific attending to foliar applications .
research lab and field studies have shown that the nematode , Steinernema carpocapsae – Koppert ’s Capsanem product – effectively kills the young box tree moth larvae ( Cydalima perspectalis ) . It is advocate that the nematodes are utilize when there is a high-pitched humidity level around the farewell . This aids the nematodes to keep alive long enough to search for their prey and kill it . ‘ But the nematode worm remain animated on the leaves much longer then expect , which makes Capsanem an essential solution for box Sir Herbert Beerbohm Tree growers and public greens ’ , Cyrille ads . More research is need though , that ’s why the Research&Development squad at Koppert is dedicating more research into foliar covering also in the coming years .
