What is Xiaohei Fei?
During the process of home gardening care, a tiny insect known as Xiaohei Fei often troubleshoots plant enthusiasts. Although this pest, scientifically named Sciarid Fly, does not bite humans, its reproductive characteristics and activity patterns pose potential threats to the home environment and plant health. This article will delve into the living habits of Xiaohei Fei and systematically elaborate its true impact on flowering plants.
Biological Characteristics of Xiaohei Fei
Basic Insect Attributes and Habitat
The adult Sciarid Fly is about 2-3 millimeters in length, with phototropism and hygroscopy, and繁殖 fastest in a moist environment of 25-30℃. Its life cycle includes four stages: egg, larva, pupa, and adult, with the larval stage being the most harmful to plants.
Actual Harm of Xiaohei Fei to Flowers
Analysis of Root Damage Mechanism
Larvae feed on the new fibrous roots of plants, causing damage to the absorption function of the roots. This is particularly evident in succulents, orchids, and other fleshy-rooted varieties, with affected plants showing typical symptoms such as growth stagnation and wilted leaves.
Risk of Secondary Diseases Induced
Bite wounds are prone to fungal infections such as root rot, with data showing that the incidence rate of infected plants is 67% higher than that of normal plants. Complex diseases often lead to complete plant death within 3-5 weeks.
Three-dimensional Control Strategy System
Key Points of Environmental Control
Keep the surface of the cultivation medium dry and use inorganic mulching materials such as Akadama soil. Implement sealed fermentation of kitchen waste to eliminate breeding grounds for eggs.
Physical Control Methods
Hang yellow sticky insect boards (20×25 cm specification is optimal), combined with supplementary lighting for nighttime trapping, which experiments have proven can reduce the number of adults by over 85%.
Chemical Control Plan
Isofenphos 2000 times solution for root drenching, with a medication cycle of 7-10 days, continuous application for three times can eliminate larvae. During the outbreak of adults,配合 pyrethroid aerosol for spatial disinfection.
By establishing a complete protection system of prevention, monitoring, and governance, the population of Xiaohei Fei can be effectively controlled. It is recommended to check the potting soil condition regularly, and combine biological control methods (such as releasing nematodes) to form a long-term prevention and control mechanism to ensure a healthy growing environment for plants.
