Control of termites in pineapple

Termites are also called worms, commonly known as termites, big water ants, rising water ants and shed insects. It is an insect of Insecta and Isoptera. It is one of the five major pests in the world.

Symptom termites are harmful to roots, stems and leaves, which often live on them, which can induce pineapple wilting and soot disease, resulting in irregular growth of orchard plants, weakening of trees and postponement of fruiting period.

The head can rotate freely and has chewable mouthparts. There are three segments in the chest, each bearing a pair of feet. The middle and posterior chest of winged adults have a pair of wings, and the shape, size and vein phase of the anterior and posterior wings are almost similar, so they are called Isoptera. There are 10 segments in the abdomen, with a pair of segmented tail whiskers at the end, and a pair of unsegmented abdominal spines in the middle of the posterior edge of the 9th web of most species.

Termites are social insects and are composed of various grades. Ant nests are generally in secluded places with small holes up and down, queens specializing in spawning and males specializing in mating. The speed of egg piercing is fast. Long-winged adults can fly in groups when the environment is suitable in a year. The grouping period varies according to the species and environmental conditions of termites. In dry areas, the clustering period is mostly in the rainy season or before and after showers, which is closely related to atmospheric humidity. Termites can not do without water, generally live in dark and wet places, leaking rain is often its gathering place, non-mating period mainly depends on crawling movement. The main natural enemies are big black ants and small black ants.

Prevention and cure method

The main results are as follows: (1) strengthen orchard management, increase rotten organic fertilizer, reasonable irrigation, maintain proper temperature and humidity of orchard, and pay attention to drainage measures. Improve the disease resistance of the tree. Combined with pruning, clean up the orchard in time to reduce the source of insects.

(2) protect and utilize natural enemies. The main natural enemies are big black ants and small black ants.

(3) the ant colony can be killed by spraying plants with 40% trichlorfon 600 times after chemical control, or spraying termites on the ant road.

Trichlorfon is commonly used.
