Golden tortoise beetle larvae
This article introduces topics related to the cultivation of flowers by golden tortoise beetle larvae, specifically as follows:
For large rose seedlings that have been growing for several years, the most feared pest in summer is the borer, because the damage caused by borers is significant, and it is not easily detected in the early stages. By the time it is discovered, the rose seedlings are often on the verge of death due to borer damage. Now is the right time to prevent borers.
Golden tortoise beetle larvae
Golden tortoise beetles are active at night and eat tender leaves, flower buds, and fruits. The adult golden tortoise beetles do not cause much harm to roses, but they lay eggs in May. If the roots of the roses are laid with eggs by the adult beetles, the larvae will hatch in June.
The larvae of the golden tortoise beetle will lurk underground for a long time, feeding on the roots of the roses. If they are not detected and dealt with early, the main roots of the roses will be bored through by the larvae, causing the roses to gradually show signs of slow growth, yellowing branches, and sudden withering. In severe cases, the entire plant will wither, especially the climbing roses, which, once bored by the larvae of the golden tortoise beetle, can result in significant losses.
Golden tortoise beetles prefer to lay eggs in the roots of roses that have been fertilized with raw manure. Therefore, if your roses have been buried with raw manure in winter, you should now pay attention to prevention and control.
Since the larvae of the golden tortoise beetle are active underground, they are difficult to detect in the early stages. Now is the stage of hatching and the best time for prevention and control. It is recommended that you can shallowly bury insect repellent granules or phoxim granules around the roots of the roses for prevention and control.
Longicorn larvae
The larvae of the golden tortoise beetle bore into the main roots of roses, while the larvae of the longicorn bore into the main stems, which is equally fatal to the roses. Especially for the 'Candy Cane' roses, once the main stem is bored by the larvae of the longicorn, the entire plant will be completely ruined.
Now is the season for the longicorn to lay eggs and for the larvae to hatch. If you see adult longicorns, you must kill them immediately. Do not show mercy to pests. In addition to shallowly burying insect repellent granules or acrinathrin granules around the roots of the roses, you should also pay attention to observations. If you see boreholes or sawdust-like material at the roots of the roses, it indicates that the larvae of the longicorn have bored into them, and you need to kill the pests immediately.
If you can find the boreholes of the longicorn larvae, you can bend a piece of wire into a hook and insert it into the hole to try to hook out the larvae. If you can't hook them out, you can use cotton soaked in insecticide and stuff it into the borehole, which can also poison and kill the larvae.
Whether it is the larvae of the golden tortoise beetle or the longicorn larvae, prevention is the main strategy. Early detection and treatment can avoid more damage to the roses. Act quickly and give your roses a comprehensive prevention against underground pests.
The above information about the larvae of the golden tortoise beetle and the longicorn larvae is hoped to be helpful to you!
