Many flower lovers always find that the leaves of the month are inadvertently missing a large piece, and sometimes the leaves of the whole month are incomplete, resulting in the whole plant growth being affected. Most flower lovers do not carefully look for clues, and they have never found the reason? Today, [Youzhi Gardening] finally "guarded the plant and waited for the rabbit" to find the real culprit for everyone - leaf-cutting bees. Let's take a look at the "crime" scene of the leaf-cutting bee and get to know its super high skills!
The leafcuttering bee, also known as the rose leafcutter bee, is a species of bee in the genus Leafcutter in the family Hymenoptera.
When nesting, the leafcutter bee goes to its favorite plants (such as roses, rhododendrons, redbuds, etc.), uses the upper jaw to bite off the round leaves with a diameter of about 20 mm on the leaves, brings them back to the nest, rolls them into a cylinder and closes one end to form a nest chamber.
Q: How are leaf-cutting bees controlled?
A: If the amount of occurrence is large, it can be sprayed on the plant during the peak of adult or larval occurrence2. 5% cypermethrin emulsion 1500 times liquid or 80% dichlorvos emulsion 1000 times liquid or 50% borer pine emulsion 1000 times liquid.
I hope that everyone has a certain understanding of the leaf-cutting bees above, and strengthening daily management and protection can prevent leaf-cutting bees from frequently stealing leaves in the moon!
