Rose leaf sawfly pest control methods, absolutely effective
As the weather gets hotter, the pests on roses also increase. Recently, many flower enthusiasts have noticed small green caterpillars on the leaves of roses. What are these rows of small green caterpillars? How to prevent and treat them?
First, let's find out what these small insects are and where they come from. At first glance, these small insects seem to be quite organized and disciplined, lined up neatly on the leaves of rose flowers, eating the leaves.
Actually, these small insects are the larvae of rose leaf sawflies. In early spring, roses are most afraid of stem sawflies. Rose stem sawflies lay eggs in the tender plants of roses, causing the new branches of roses to suddenly wither.
As spring approaches summer, rose leaf sawflies are prone to appear. The sawflies lay eggs in the branches of roses, and after the eggs hatch, these small green caterpillars appear.

The destructiveness of rose leaf sawflies is immense. After the larvae hatch, a large number of sawfly larvae gather in groups and frantically eat the leaves of roses. Often, by the time we notice the sawfly larvae, the leaves of the rose branches have been eaten up.
How to prevent rose leaf sawflies?
It is really not easy to prevent rose stem sawflies. They can fly, coming and going without a trace, laying eggs and then flying away. Anyway, whenever you see something similar to a flying bee on roses, you should definitely kill it.
If you find a line-like scratch on the branches of roses, you should be careful, as it is basically the sawflies have laid eggs. At this time, you can apply insecticide to the wound to kill the eggs, but this initial stage is difficult to detect.
Usually, when rose leaf sawfly larvae are found, they have already hatched and grown a bit larger, and a lot of leaves have been eaten.
