Aphid is an insect that causes major problems in horticulture. All types of aphids on plants occur throughout the year and cause fading of the young shoots in a crop. Royal Brinkman offers a wide range of biological products for aphids control in professional greenhouse horticulture.

The most common aphid species in greenhouse crops are the cotton aphid Aphis gossypii, the buttercup aphid Aulacorthum solani, the potato aphid Macrosiphum euphorbiae and the green peach aphid Myzus persicae. All aphid species need a different biological control. Some aphids transfer toxic substances to plants, causing an allergic reaction of the plant. Aphids can also transmit some viruses. Controlling aphids is very important to prevent damage. 

Aphid control can be achieved by using beneficial insects, such as the parasitic wasp. Biological control against aphids is increasingly done with natural enemies, because the resistance against allowed insecticides increases. 

The parasitic wasp is most commonly used to control aphids. The parasitic wasps find aphids in the crop even before the aphids can be seen with the naked eye, which makes these parasitic wasps very suitable as a preventive against aphids. Aphids cannot arm themselves against these parasitic wasps. But wich wasps against aphids are available? 

• Aphidius colemani: is used to control aphids. The adult parasitic wasps hatch and parasitize aphids by laying an egg in them. The parasitic wasps find aphids in the crop even before the aphids can be seen, which is why these parasitic wasps are very suitable for preventive use. Remark with these parasitic wasps is that empty mummies remain on the crop. In some crops this can be at the expense of the ornamental value. In vegetable crops this does not play a role. 
• Aphidius ervi: is used to control aphids. The parasitic wasp parasitizes the aphid by drilling a hole in the aphid and then laying an egg in the aphid. The laid egg grows in the aphid, mummifying it and eventually a new parasitic wasp emerges. 
• Aphelinus abdominalis: is used to control potato aphid (Macrosiphum euphorbiae) and buttercup aphid (Aulacorthum solani). The female injects the egg with her ovipositor into the aphid. 
• Aphidius matricariae: is used to control peach aphid (Myzus persicae), tobacco peach aphid (Myzus persicae var. Nicotianae) and peach potato aphid (Myzus persicae var. Persicae). This parasitic wasp also contributes to the disturbance of aphid populations as buttercup aphid (Aulacorthum solani). The female injects the egg with her ovipositor into the aphid.
