I have been raising Hawaiian bamboo for 4 years and have a lot of bugs on it? 5

There are a lot of small insects growing on the Hawaiian bamboo, which may be caused by scale insects. Here's how it can be handled:

1.Use liquor to water, the share is 1 2, and water the surface layer of potting soil when treating insects. Scale insects begin to move at room temperature 7 in spring. It can be watered once in April, and then once every half month or so, and it is effective for 4 times in a row.

2.With 50 ml of vinegar, put a small cotton ball into the vinegar and soak it, and gently rub it on the stems and leaves of the damaged flowers and trees with a wet cotton ball, and the scale insects can be wiped off and killed. This method is convenient and safe, which can not only achieve the purpose of insect removal, but also make the damaged leaves green and shiny again.

3.Gently rubbing the diseased plant with alcohol can remove the scale insects, and the removal is very clean and thorough. For example, when the diseased leaves of orchids are scrubbed with alcohol, not only can the scale insects be removed, but the larvae that are not visible to the naked eye can also be completely killed.

4.Spray with smoke infusion, or irrigate with 200 to 300 times the dilution of laundry detergent. In the oviposition and larval hatching period of each generation of adults, one treatment should be carried out every 7 to 8 years, and two or three times in succession should be carried out, which can basically control the harm of contemporary scale insects.

If the above methods do not work well, or if the situation of bugs worsens, it is recommended to consult a professional botanist or horticultural expert for further diagnosis and guidance.

It is a kind of insect that likes shade and dampness, not phoenix bamboo.

Like to give birth to this kind of insect, but when the potting soil is not exposed to the sun and the drug insecticidal eggs are caused (if the place where you place the anchovy bamboo is dry), the killing method can only be killed with drugs, because you can't pour out the entire potting soil and replace the anchovy bamboo that has been potted, which will cause great damage to the plant. Go to the flower and bird market and buy killing drugs, such as carbofuran.

Trichlorfon and Avi nematode elixir can be used, just follow the instructions at the back of the bag. Of course, it is also important to keep the breeding environment dry and clean.

Whitefly is also known as greenhouse whitefly and small white moth. It is an important pest for flowers, and there are more than 200 kinds of flowers and plants in 16 families.

Morphology: Adult: body length mm, wingspan mm, body light yellow, wings white covered with white waxy powder.

The beak is well developed. The antennae are short filamentous. Eggs:

Oblong in shape, pale yellow at birth. Brown after that. Larvae:

Body length mm, oblong, oblong, flattened, pale green. There are white radial wax filaments around the body. Chrysalis:

Oval, slightly raised, pale yellow, or light brown, the back of the pupal shell is covered with white wax filaments.

Occurrence law: perennial damage in the south and perennial damage in the northern greenhouse. 9-10 generations occur in a year, with overlapping generations.

During the same period, there were various insects. Adults are generally inactive. However, when the temperature is high and the sun is sufficient, it can fly between the plants, and it can also fly in groups if it is slightly alarmed, and it often gathers on the back of the leaves, and has a tendency to yellow and white.

Whiteflies generally suck sap on the back of the upper leaves, causing the leaves to turn yellow and wilt.

Control methods: It is very important to control whiteflies in the northern greenhouse in winter, which is related to the density of the insect population in the following year. Use deltamethrin 2000 times or 10 xylphate EC 1000-1500 times; 40 dimethoate 1000 times liquid or 50 pine borer 1000 times liquid spraying.

Spray 1 time in 7-10 days, 3-4 times in a row. Taking advantage of its yellow tropism, yellow plastic plates can be hung between the rows of plants, and a layer of heavy engine oil can be brushed on the plates, and the plants can be shaken appropriately to make them fly away to increase the sticky killing effect. Biocontrol.

The use of aphid wasps can control the base number of whiteflies.
