Spider mites and other mites

Biological control of spider mites and other mites uses a range of natural enemies that target different developmental stages of the pest: Predatory mites [...] on the leaves affect the appearance of the crop. This is of particular concern in ornamental crops. Life cycle of spider mites Spider mite control videos [...] are capable of causing severe damage very rapidly due to their great reproductive capacity. There are more than 1200 species worldwide, many of them are common

Caterpillars

addition to consumption of the plant, caterpillars also spoil the plant with the large quantities of frass they leave behind. Life cycle of caterpillars Caterpillar [...] crops. Biological control of caterpillars combines monitoring and control strategies that target different life stages of the pest: Beneficial nematodes [...] damage crops. Most of them feed on nectar. In contrast, the caterpillars have biting and chewing mouthparts and can devour large amounts of plant tissue. Many

Aphids

for maintaining healthy, productive crops. Biological control of aphids uses a combination of natural enemies that attack aphids in different ways: Parasitic [...] Aphids can be a variety of colors, including green, yellow, black, brown, pink, or red, depending on the species and their stage of development. Some species [...] lead to the growth of a black sooty mold. Aphids life cycle Aphid damage Depending on the species, aphids can inflict various types of damage to a crop:

Macrolophus pygmaeus

Consumption of plant sap, however, can cause damage to crops such as certain varieties of tomato, and gerbera. Conditions that promote the onset of such problems [...] problems include a shortage of prey, a high population of bugs (more than 100-150 per plant), and a weak crop. More delicate types of tomato are more susceptible [...] conditions for use of Macrolophus pygmaeus Optimal temperatures for Mirical are above 20°C/68°F, lower temperatures slow down the development of Macrolophus pygmaeus

Direct damage is the immediate result of larvae feeding on root hairs and [...] nuisance, are particularly small flies of the families Sciaridae (sciarid flies) and Ephydridae (shore flies). The larvae of these insects generally live on rotting [...] to plants, they are often a problem due to their large number. Larvae of flies of the family Keroplatidae (mainly Lyprauta sp.) can cause damage in potted

Onion thrips

The excess sugar is secreted in the form of honeydew, making the crop and its fruit [...] they are also capable of dispersing through the crop by walking. The tobacco aphid tends to form denser colonies, closer to the top of the plant, than the [...] viruses. Life cycle and appearance of Tobacco aphid Aphids have a complex life cycle, with both winged and wingless forms of adults and a great variety in colour
