Common Pests of Aloe Vera
As a widely popular succulent plant, aloe vera often faces pest threats during its care. This article systematically sorts out the characteristics and scientific control methods of three major aloe vera pests, accompanied by high-definition real shot identification, to help you protect the health of your green plants.
Aloe Vera Bollworm Control System
Pest Characteristics and Hazards
The bollworm larvae cause perforations and defects by eating the tender leaves, which can severely lead to plant growth stagnation. The adult moths are 14-18mm in length and have a wingspan of 30-38mm, with phototactic characteristics, and can breed 3-5 generations per year.
Comprehensive Management Plan
1. Physical Control: Hang black lights (wavelength 365nm) to attract and kill at night, with 2-3 lamps set per mu. 2. Biological Control: Release natural enemies such as Trichogramma, with 5000 heads per mu. 3. Chemical Eradication: Spray 40% omethoate 800 times solution during the larval stage, focusing on the back of the leaves.
Aloe Vera Scale Insect Control Strategy
Pest Identification Points
Mainly affects varieties such as soap aloe, with female insects 1-3mm long and elliptical in shape, secreting wax to form a protective shell. Affected leaves show yellow spots, and honeydew induces sooty mold disease.
Step-by-Step Treatment Process
1. Initial Treatment: Use 75% alcohol cotton swabs to physically remove the pests. 2. Pesticide Spraying: Spray 50% trichlorfon emulsion 1500 times solution, focusing on the leaf axils. 3. Environmental Regulation: Maintain ventilation and light, and control air humidity to ≤65%.
Aloe Vera Red Spider Mite Eradication Plan
Seasonal Outbreak Patterns
The optimal breeding temperature is 25-30°C, and it completes the generation alternation in 7 days in a dry environment. Initially, the leaves show needle-like chlorotic spots, and in severe cases, web formation affects photosynthesis.
Comprehensive Control Measures
1. Preventive Measures: Clear surrounding weeds in winter and spray lime sulfur solution to enclose the garden. 2. Chemical Control: Alternate between 40% omethoate and 20% pyridaben 2000 times solution. 3. Ecological Regulation: Regularly spray the leaves to maintain environmental humidity ≥70%.
By establishing a four-dimensional control system of pest monitoring, physical control, biological regulation, and precise medication, combined with maintaining environmental cleanliness and reasonable fertilization to enhance plant resistance during daily maintenance, the occurrence of aloe vera pests can be effectively controlled. It is recommended to conduct systematic inspections monthly, to detect and handle issues early, ensuring the healthy growth of aloe vera.
