I have 5 pots of roses in the balcony and all of them have had their leaves cut out by the leafcutter bee. The worst damaged plant has 70-80% of its leaves cut with holes. and the holes the bee cuts out aren't small either, about 1/2 to 2/3 of the leaf is cut away. quite a few of the leaves only left the center leaf vein part.

Is there anyway to shoo/chase/catch the bee? I know such bees are helpful in pollinating but im worried that the rose plant might go into shock from having large parts of nearly all its leaves cut out, and my plant dosen't have that many leaves to begin with. My plants are all starting to bud and bloom, will they start producing more leaves to replace the damaged ones at the expense of flowers??

i tried putting other plants like azaleas that the bee supposedly likes to cut around the roses to hopefully persuade the bee to cut the azaleas instead of roses but the bee still continues to cut my rose leaves everyday!! and the azalea plant does not even have a single leaf cut! the bee cuts out 4-5 new holes everyday, at this rate my rose plants would have no more full leaves left! :(/> :(/>

please help~~:(/>

Hi Wei - I'm curious - how did you conclude that the damage was done by leaf-cutter bees? Did you actually get to see them? The reason I ask is that I have had rose leaves in the past similarly cut, sometimes just as holes in the middle of the leaf, and found out that the culprit was small black beetles that come out only at night. The only way to get rid of them that I knew, was to do periodic inspections at night with a torch, and pick them off.

thx keling.

mm> i know it was a bee cos i saw a black insect buzzing around my plants. it didn look like beetles. i also check my plants at night cos im quite paranoid about insects in my balcony lol but i didn find any beetles. i actually tot it was a flying ant at first until i managed to look closer, but until now i never seen the bee actually cutting the leaves, only saw it flyign abt. but everytime i count got more n more holes and more leaves damaged. sumore the holes cut out of my rose leaves have perfectly round edges wich looked like those leafcutter bee damage. so im thinking it must be the bee=X

i hope it goes away soon though!! i've seen the bee in my balcony everyday since the 23rd :angry2:/>

According the webpage linked above. You can fix the problem by killing the one and only bee that you saw. Its nest should be very near the plant.

i would urge u to be more tolerable toward bee. As bee population has been declining alarmingly because of parastic mite, killing them at a very fast rate. After all it is just one or two bee. Good news is it does not harm the plant.
