OLD TYRES AND MILK MAKE BEST MOZZIE TRAPS

The Witness - Wheels - - FRONT PAGE -

Re­searchers with the Grand Chal­lenges Canada ini­tia­tive have com­bined mos­qui­toes’ love for old car tyres and their own chem­i­cal ex­per­tise to de­sign a highly-ef­fec­tive trap us­ing two halves of an old tyre. The rub­ber is ‘sig­nif­i­cantly more ef­fec­tive’ at at­tract­ing mos­qui­tos than plas­tic bot­tles or buck­ets. They call the trap the ovil­lanta, and use the mos­qui­toes’ habit of re­leas­ing pheromones in wa­ter con­tain­ing mozzie eggs against the in­sects. Users mix wa­ter and a milk­based non-toxic so­lu­tion, de­vel­oped at Sud­bury’s Lau­ren­tian Univer­sity to at­tract mos­qui­toes, and place the mix in the trap with a twig or piece of pa­per for the fe­male to lay the eggs on. Ovil­lanta own­ers burn these once a week, but re-use the wa­ter, as more pher­e­mones at­tract more mozzies to make the trap in­creas­ingly ef­fec­tive.
