For many years, the parasitic wasp Encarsia Formosa was the only natural enemy used against whitefly. It is capable of using various species of whitefly as hosts. The female deposits her egg in older stages of the whitefly larvae.

The predatory mite Amblyseius swirskii feeds on a wide range of prey. It can develop and reproduce while feeding on non-prey food sources such as pollen. This allows the predator to build up populations before the pests are present.

Gall midges are found almost worldwide. The Feltiella larvae feed exclusively on spider mites.They are often introduced but from May to September also occur spontaneously in numerous crops. Feltiella creeps up on its enemy and uses its mouthparts to immobilize it.

This parasitic wasp is well-known for its use in the biological control of mealybugs. Anagyrus parasitizes different stages of mealybugs. The wasp actively searches for its prey. Anagyrus stings the mealybug with its ovipositor to paralyze it.

Parasitic wasps are very often used to control populations of agricultural pests. Aphelinus first searches its prey with its antenna. Then it swings around and curls up the tips of the wings. The female stabs her ovipositor into the aphid, to paralyze it.

Parasitic wasps are very often used to control populations of agricultural pests. Aphidius has very effective searching behaviour. Once the female has made contact with its host she stabs her ovipositor into the aphid to deposit an egg. All larval stages of Aphidius grow inside the aphid.

Amblydromalus limonicus is widely used for the biological control of thrips. It is capable of controlling high infestations quickly and effectively due to its great reproductive capacity. Limonicus pierces its prey with its mouthparts and then sucks out the contents.

R&D departments at several Koppert locations have been researching foliar applications of our nematodes for several years. Senior Researcher Dr. Magda Galeano (R&D Micro - Koppert Spain) explains the steps taken.

There are different mode of actions by which Trianum can affect a plant pathogen. In this video you can see a direct effect of Trianum (Trichoderma harzianum T22) on a severe soil-born pathogen Pythium ultimum.

This video shows the effect of Trianum (Trichoderma harzianum T22) on Fusarium wilt disease of tomato. Fusarium-infected seedlings struggle to emerge, get rotten and die. Application of Trianum combats Fusarium, protects the seedlings and stimulates their growth.

A healthy plant starts with a healthy root system. Trianum (Trichoderma harzianum T22) is well-known for its ability to control disease-causing soil-born fungi such as Fusarium graminearum.

Tuta absoluta is a very harmful leaf mining moth. It occurs on eggplants, sweet peppers as well as potatoes and various other cultivated plants, but has a strong preference for tomatoes. Tuta absoluta can cause 50-100% yield reduction on tomato crops. Adult females lay eggs on host plants.
