Age 2 and age 3 are in green. Age 4 and age 5 are golden brown and 2 small wing sprouts.

Green bugs specialize in the fruit of citrus groups (oranges, tangerines, lemons, grapefruits, kumquats...), some people call them orange bugs, or orange suckers. Their scientific name is Rhynchocoris poseidon or Rhynchocoris humeralis.

 In Vietnam, yellow leaf curl disease is very common on papaya trees, especially the disease is often severe in areas of high and continuous planting, areas with hot and arid climates. The disease has significantly reduced the yield and quality of papaya. Gardens that are infected early when the plants are young may not yield. However, up to now, many gardeners still do not know the cause and how to fix it.

 Spider mites are common pests on citrus trees, especially in hot and dry climates that are suitable for spiders to grow and cause severe damage.The group of harmful spiders is usually very small in size, unlike the natural enemy spiders.Spiders have a very short life cycle, high reproductive ability, create many generations in a year, so it is easy to break out into epidemics in a short time.

 This group includes species that are generally very small in size, causing damage by sucking plant sap (on leaves, fruits, branches, stems).

There are many species of mealybugs present on the group of Oranges,Tangerines,Grapefruits and Lemons (Citrus), which can be divided into 2 groups:

+ Group of sticky mealybugs with common varieties such as Lepidosaphes, Aonidiella, Coccus and Saissetia.

+ Group of flower mealybugs with common genera and species such as Pseudococcus, Planococcus and Icerya purchasi.

 In general, insects, spiders and plant pests are divided into the following groups:

1. The group of leaf-eating caterpillars

Harm by using mouth to eat parts of plants, especially leaves, because the caterpillars are missing, the plants grow and develop poorly, leading to reduced yields, In addition, wounds caused by pests are also a gateway for fungi and other bacteria to enter and cause harm.

The disease usually affects lemon and grapefruit, the disease affects all parts of the tree. On oranges, tangerines are less affected. On lemons, the disease usually affects leaves. The disease attacks anywhere on the leaves, but usually affects the tips of the leaves and the edges of the leaves.Anthracnose lesions are yellow-brown, then grow larger, slightly rounded, surrounded by dark brown borders.
