Pests| Aphids | Bulb mite | ||
| The population growth of aphids can be sometimes very fast, leading to great damage in several crops. It is therefore very important to locate the aphids and take necessary measures. Biobest offers a whole series of parasitoids and predators against aphids. |  |
Frequent pests in bulbous plants
Bulb mites can cause a lot of damage in the bulbgrowing industry. In particular during the multiplication of bulbs and their culture. Thanks to the predatory mite Hypoaspis aculeifer an effective biological control is recently possible. |
 |
| Caterpillars | Coddling moth | ||
| Voracious on several crops Caterpillar damage usually occurs in late summer and early autumn, but recently some caterpillars have been causing problems throughout the growing season. There are several biological control methods of caterpillar control. |
 |
Coddling moths can cause serious losses in apple and
pear cultures by infecting fruitlets which results in premature losses
or storage problems. |
 |
| Greenhouse Whitefly | Garden chafer | ||
| The greenhouse whitefly (Trialeurodes vaporariorum) is a typical greenhouse pest that affects many crops. |  |
Several kinds of beetle larvae can cause a lot of damage in grass fields and lawns. These larvae are also known as 'grubs'. The garden chafer is the most commonly occurring species. |  |
| Leaf hopper | Leafminer | ||
| For several years now the presence of Cicadidae (Hauptidia maroccana) has increased, especially in tomato culture. |
 |
Leafminers cause a lot of visual damage in different crops because the larvae eat mines in the leaves. Especially in ornamental plant cultivation crops a little infestation can cause already a lot of damage because then the product is not saleable anymore. |  |
| Mealy bug | Pear psylla | ||
| Mealy bug is one of the hardest pests to control. Its body is covered with white waxy threads, which often make a chemical pest control little successful. |  |
Honeydew stains pears black. This is a nightmare for
any pear grower. |
 |
| Sciarid fly | Shore flies | ||
| Sciarid flies are small, black insects (3-5 mm) with slender antennae and long legs. Especially the larvae cause a lot of damage. |  |
Shore flies are little, black insects. They do not have antennae like the Sciarid fly. The presence of shore flies decreases the marketability of finished products. |  |
| Slugs | Spider mite | ||
| Slugs can devour the equivalent of half their body weight within 24 hours. The damage they cause can occur both aboveground and underground. |  |
A population of spider mites can grow very rapidly, especially under dry and warm conditions. Fast action is recommended to keep the spider mite densities as low as possible. |  |
| Thrips | Tobacco whitefly | ||
| Adult thrips are small, elongated insects with typical fringed wings. They measure about 1 mm, and have a greyish or yellow to brown colour. The two most common harmful species are the onion thrips (Thrips tabaci) and the western flower thrips (Frankliniella occidentalis). |  |
In countries with a mild climate, the tobacco whitefly (Bemisia tabaci) is a common pest. | |
| Vine weevil | |||
Adult weevils feed at night producing telltale notches
around the edges of leaves and flowers. The damage is most severe
when caused by the voracious larvae, feeding on roots. Heterorhabditis-System
provides rapid and effective control of vene weevil. |
