Management of Coconut Diseases and insect pests: diseases, hazards and Control methods of Coconut scale insects

What is the harm of coconut diseases and insects? How to prevent and cure it?

Ecological habits: there may be 10 generations per year, and one generation takes about 33 days. Parthenogenesis is usually carried out, and the mother lays eggs under the shell around the mother. The spawning period is 8-10 days, and each female can lay 40-155 eggs. Overwintering as adults. In recent years, it mostly occurs in the dry season, mostly from September to May of the following year, but it may also be rampant when it has not rained for a long time in summer. The diet is miscellaneous and there are many hosts. Newly hatched larvae can crawl on their own and can be spread to other places by wind, birds, insects and human factors, and their distribution and damage will be affected by rainfall, wind, temperature and coconut development.

Damage: the leaves of the injured plants were damaged due to chlorophyll and tissue, and the moisture was absorbed, showing a withered and yellow phenomenon, and the serious ones were on the verge of dying, resulting in an unprecedented disaster of cocoa coconuts in Taiwan.

Prevention and control methods:

First, improve management so that coconuts can develop well. in addition, they can be used as other crops or improve the ecosystem in the coconut cultivation area, so that natural enemies can get a good environment and reduce the damage.

Second, predatory Coccinellidae natural enemies can be introduced, among which Cryptognatha nodiceps and C. politus are more promising.
