How to Prevent and Control玫瑰 Rosette Leaf-cutting Bees
Today's focus is on introducing how to prevent and control the leaf-cutting bees that harm rose Rosette, let's follow the editor to take a look!
The rose leaf-cutting bee (Scientific name: Megachile nipponica Cockerell) is an insect that specifically harms plants from the Rosaceae family such as roses, roses, and roses. They cut the leaves of plants to build nests and lay eggs, causing damage to the plants. Here are some effective control methods.
1. Manual Capture
Since leaf-cutting bees usually act alone, adult insects can be captured manually to reduce the source of pests. During the peak activity period of adults, use a net or electric fly swatter to capture them, which requires time and patience.
2. Remove Leaves with Eggs
During the egg-laying period, regularly inspect the plants and remove leaves with eggs in a timely manner to reduce the number of larvae that hatch.
3. Change Plant Location
Leaf-cutting bees have a preference and memory for the egg-laying location. By moving the pot or plant, you can confuse the leaf-cutting bees so they cannot find a place to lay eggs.
4. Use Insect Repellents
Leaf-cutting bees do not like pungent odors. You can apply insect repellents such as eucalyptus oil around the plants. Since eucalyptus oil is volatile, it needs to be replenished regularly.
5. Chemical Control
Chemical pesticides can be used for control during the peak period of adult emergence or the occurrence of larvae. For example:
50% fenvalerate emulsion 1000 times dilution80% dichlorvos emulsion 1000 times dilution
2.5% bromide emulsion 1500 times dilution
When using chemical pesticides, be sure to pay attention to safety, follow the product instructions, and alternate the use of different types of pesticides to delay the development of resistance.
6. Biological Control
Encourage and attract natural enemies of leaf-cutting bees, such as ladybugs and spiders, to reduce the number of leaf-cutting bees through biological control.
7. Preventive Measures
During the active season of the rose leaf-cutting bee, regularly inspect the plants, especially the upper middle part of the leaves, to detect and deal with leaf-cutting bees in a timely manner. Keep the plants healthy, as healthy plants are more resistant to pest invasion. Prune the plants properly to maintain good ventilation and lighting conditions, reducing hiding places for leaf-cutting bees.
Precautions
When using chemical pesticides, ensure the safety of humans and animals, and avoid using them in areas where children and pets are active. Follow local pesticide use regulations and use pesticides rationally. Protect the environment, minimize the use of chemical pesticides, and prioritize physical and biological control methods.
Through the comprehensive application of the above methods, the leaf-cutting bees can be effectively controlled, protecting the health and beauty of roses and other Rosaceae plants.
