The greenhouse whitefly, also known as the white moth and whitefly, is capable of killing more than 100 vegetables and flowers, which can occur in Beijing for an annual anniversary. Its adult wings can migrate, other insect states can also spread with the air flow and agricultural production, combined with rapid reproduction, generation overlap, population growth is extremely fast, easy to produce drug resistance, prevention and control is more difficult. Based on the prevention and control of agriculture, comprehensive prevention and control measures should be taken to control the source of insects, reduce the population in the field, and reduce the damage.
Agricultural control
Clean pastoral. After removal of the old leaves and harvesting, clean up the plant debris as soon as possible, harmless treatment according to local conditions; timely remove weeds in the vegetable park, especially around the shed.
No pests are cultivated. When growing seedlings, separate the seedbed from the production greenhouse. The surface of the greenhouse should be disinfected before nursery. During the nursery period, a small amount of yellow plates were hung to monitor the whitefly and timely control. The air outlet was isolated with a 40-mesh insect net. Make sure the transplanted seedlings are free of insects when planting.
Arrange your mouth properly. Implementation of greenhouse whitefly breeding and non-food crop rotation, to avoid eating host cucumber, tomato, eggplant, pepper, beans and other vegetables mixed interplanting, protection of autumn and winter wolfberry can be cultivated leeks, rape and celery greenhouse whitefly do not like to eat vegetables.
Physical control
Cover insect nets. In the planting shed, 30-40 mesh insect screens are used to close vents or to set up isolation doors. Insect nets should be regularly inspected and repaired in a timely manner. The insectproof doors should be sealed. There is a condition that two buffer doors can be used to set up a buffer room, and 3-4 yellow boards can be suspended in the middle for better results.
Yellow plate or yellow pot trap. The initial use effect is good. Place 25 centimeters, 40 centimeters per mu, and 20-25 yellow boards. The lower end of the board is about 5 centimeters higher than the top of the plant. Change the amount of the insects as soon as possible. Yellow pots can be used to fill the water, and a certain amount of laundry can be put inside. The powder was placed at a height slightly lower than the growth point of the plant. About 15 cm in diameter and about 10 yellow pots were placed per acre, and surface floating insects and water changes were promptly removed.
Biological control
Use broad-spectrum insecticides with caution to protect and use the natural enemies of whiteflies in the greenhouse, including grasshoppers, small-flowered locusts, and lisianthus. When low density occurs, larvae can be released by artificial control. When the adult population is below 0.5 per plant, the density of the larva is 15 animals/plant, and when the amount is large, the release density is appropriately increased, and the larva is released once every 10 days, or 3-4 times depending on the situation, which is conducive to control. Pest population growth.
Chemical control
The greenhouse whitefly needs to be controlled when spotting occurs in the field. Spray control optional insecticides include 25% thiamethoxam water dispersible granules, 200 g/l imidacloprid solution, 20% high-chlorobuprofezin EC, 25 g/l bifenthrin EC, 10% chlorothiazide The morpholine wettable powder, 20% acetamiprid solution and 22.4% spirotetramat suspension agent, etc.; smoke prevention and control can use 3% beta cypermethrin smoke agent and 22% dichlorvos smoke agent.
Precautions
The greenhouse whitefly is not good at night, and it should be applied in the early evening or early morning. The back of the leaves should be the main application site. Spray from top to bottom in sequence. Conditional smoke application should be applied at room temperature. The greenhouse whitefly is present at the same time in the field, and currently lacks all the insecticides that can kill all insects. Chemical control should be used for 2-3 consecutive times to achieve ideal control.
