The base of propolis is a natural resin which is collected by honeybees, from buds or damaged areas on various trees, and is then processed and enriched.
As bees need a temperature of around 35 degrees Celsius to live together in the hive, good conditions prevail for the spread of diseases. Propolis is a plastic material and is therefore... | | |
| | ...ir, they are mainly encountered in greenhouses. After hatching from pupae, the females start feeding immediately. They drill small holes in the top surface of plants’ leaves using their ovipositors and suck up liquid with their mouth parts. The damaged areas on the leaf tissue (which also enable bacteria and fungi to penetrate into the plant) are clearly visible as yellowish stains.
The males live on nectar or honeydew but they can live without nutrition until they mate. The females lay their ... | | |

Lace bugs feed on plant juices, which they remove from the epidermis layer of the leaf undersides with their piercing and sucking mouth parts. When the leaf cells are empty, the damaged area is discoloured bronze or silver. Each individual spends its entire life on the one plant, if not on the same plant part.

| | Acorn weevil larvae are 9 - 10 mm long. Their bodies are yellowish-white in colour and without legs. The head is reddish-brown and lacks eyes. The larvae eat out the core of the acorn. In autumn, when the damaged acorns fall from the tree, the larvae, which have now reached their full size, bore their way out and dig into the ground, where they settle themselves in small chambers about 250 mm beneath the surface of the ground for the purpose of overwintering... | | |
