What does a pineapple worm look like (what kind of worm is as white as an egg in a pineapple)

Pineapple worm is also called pineapple powder scale insect. The scale insect's body is oval, 2 ~ 3 mm long, gray-white, covered with white wax powder, and has radial white wax filaments on its edge. When a female lays eggs, there are white cotton-like wax filaments in her abdomen. Generally, 2 ~ 12 eggs gather together and attach to parasitic plants gently.

The appearance of pineapple mealybug

The pineapple bug we often say refers to the pineapple mealybug, which is the most serious pest of pineapple. It has occurred in pineapple producing areas in Guangdong, Guangxi, Fujian, Taiwan Province and other provinces.

The body of the pineapple mealybug is oval, 2 ~ 3 mm long, grayish white, covered with white wax powder, and has radial white wax filaments at the edge.

Moreover, when the female of pineapple worm lays eggs, there are white cotton-like wax filaments in the abdomen. Its eggs are usually 2 ~ 12 together and gently attached to parasitic plants.

The onset time of pineapple worm

Generally, pineapple scale insects occur all year round in South China, with May-September as the main damage period.

Nymphs and female adults gather at the junction of leaves and stems. The low-lying, damp and cool planting areas in the garden are more conducive to the reproduction of scale insects.

Control method of pineapple mealybug

Step 1: Select seedlings.

Choose seedlings without mealybugs, and don't introduce seedlings to places with mealybugs.

The second step is to soak the seedlings.

In order to prevent the spread of mealybug, before planting, the seedlings were tied into bundles and soaked with chemicals. We used 40% dimethoate and 40% dichlorvos as 600 ~ 800 times solution to soak the roots of seedlings for 3 ~ 5 minutes. Then take it out and dry the roots upwards, so that there will be no more mealybugs on the seedlings.

Step 3: Spray.

We choose to spray turpentine mixture in pineapple orchards where a large number of scale insects occur. Prepare 20-fold aqueous solution in summer and 10-fold aqueous solution in winter. Spraying once in the diseased pineapple orchard has a good effect on killing mealybugs.

Step 4: Check regularly.

Regularly check whether there is any harm of mealybug in the garden, and use chemical agents to prevent mealybug from multiplying in large numbers before the high temperature and drought period in August-September.

If it is found that pests are expanding, it is necessary to spray 800 times dimethoate solution on the soil of plants and plant stems regularly in pineapple orchards where harm may occur.

Step 5: Centralized processing

The seriously damaged plants in the garden should be uprooted, dug out and burned centrally, and 40% dimethoate should be sprayed 600 ~ 800 times in the original planting hole to eliminate the residual scale insects in the soil.

Step 7: Eliminate communication channels.

Ants are the chief culprit in the spread of mealybug, so attention should be paid to eliminating ants in the spread soil. If ant holes are found, trichlorfon should be sprayed 800 times in time.
