Lily bee­tle’s de­struc­tive days are num­bered

Amateur Gardening - - Your Gardening News -

TIME may be up for the scar­let lily bee­tle (Lil­io­ceris lilii), a com­mon pest that is a vo­ra­cious preda­tor of lilies and frit­il­lar­ies, de­stroy­ing their leaves and flow­ers.

The bee­tle lar­vae hide un­der­neath plant leaves and cover them­selves in their own poo for pro­tec­tion.

Re­searchers at BASF’s ne­ma­tode fa­cil­ity in West Sus­sex be­lieve that Ne­masys Fruit and Veg Pro­tec­tion treat­ment may kill off the dam­ag­ing pest.

Sci­en­tists think that the ne­ma­todes (par­a­sitic worms) in the prod­uct kill the lily bee­tle lar­vae and pu­pae.

A Ne­masys spokes­woman said: “A sin­gle treat­ment may be suf­fi­cient to con­trol the pest through­out the sea­son, but as the ma­ture lar­vae and pu­pae are found in the top few inches of soil it is best to re-treat, en­sur­ing the soil re­mains moist in sum­mer.”
