Here's an overview of the life cycle of plant mites: Egg: The life cycle begins with the female mite laying eggs. The eggs [...] eggs are usually spherical and laid on the underside of leaves or on other parts of the plant. The number of eggs laid by a single female can vary, and they

The first three instars make small holes, while the following stages feed on the tissue between the veins [...] to 300 eggs on the underside margins of the upper leaves of plants. The eggs have a spherical shape, with the flattened part attached to the leaf, and are [...] green with a white band on both sides of the body. Pupation takes place in webbed cocoons often on the underside of the host plants. The pupae have a green

The damage is first seen on the lower part of the plant and moves upwards as the mites ascend. Life cycle and appearance [...] appears to be divided into two parts: the head with the mouthparts, and the rest of the body. All mobile stages have only two pairs of legs, whereas other mite

The adult [...] sucking out the sap from the plant leaves and secreting honeydew. This can have the following consequences: If the population is very large, feeding on plant [...] influence the development of fruit and lead to a reduction in yield. The honeydew deposited on fruit makes it sticky. Dirt adheres to the fruit, and the growth

The pupae do not make a cocoon [...] damage by feeding on fruits, flower buds and leaves depending on the species.

Damage symptoms The caterpillar is a surface feeder. They feed from the lower leaf surface, leaving the wax layer on the upper surface intact, thereby [...] destroyed, leaving only the veins. The larvae feed also on the chlorophyll-rich green areas of stems and pods causing whitening of the crop. Heavily damaged

Mealybugs inflict damage on the crop in various ways: nymphs and females extract the sap from the plant, stunting growth and causing deformation [...] honeydew, which, as well as the white, waxy secretion of the mealybugs, reduces the ornamental value of the affected plants. Fruit and flowers are also fouled

Damage is caused by the mites sucking out the contents of plant cells.

This results in smaller leaf size and suppressed bud

The pinkish red eggs [...] caterpillars often stay in the lower strata of the crop, sometimes attacking the stem of the plant as well as the leaves. Late instar larvae burrow into soft [...] low in the crop, often in decaying organic material on the ground or substrate. They feed on detritus as well as life materials. Young larvae feed on the
