Leaf miners

In (s [...] lost before the harvest is affected. The size of a leaf tunnel depends on the stage of development of the leaf, the species of host plant and the species of [...] various crops in temperate parts of the world. Under natural conditions, the larvae of these species are parasitized by parasitic wasps and so cause few

Bugs

[...] leaves and growing points with their piercing-sucking mouthparts and extracting nutrients from them, resulting in deformations and puncture holes. The most [...] harmful and beneficial species. Heteropteran bugs are insects which have flattened bodies and fold their wings flat over their body when at rest. The wings

Aphids

In greenhouses [...] damage to plants in several ways, and the damage can vary depending on the species of aphid and the type of plant being attacked. The following are common [...] leaves, stems, and flowers by piercing the plant tissue and sucking out the sap. This can result in stunted growth, curling or distortion of the leaves, yellowing

May beetle

From the third stage onwards, the impact of this pest increases. Damage symptoms Initial damage is not visible in the aerial [...] of the plant, as the larvae only feed on root hairs and organic material during the first and second instars. When they move to the next stage, the larvae

Aphidius colemani

typical of the Aphidiidae. First the host is examined by drumming with the antennae. This gives the wasp the information about whether the aphid is the right [...] Aphidius colemani The parasitic wasp is available in a bottle ( Aphipar ).

The bacterium Candidatus [...] solanacearum which is transmitted by potato psyllid amplifies the feeding damage and causes ‘zebra chip’ in potatoes Indirect damage causes the most harm, since [...] potatoes and permanent yellowing disease in tomatoes, both of which are very harmful to the affected crops.
