How to Use Biological Controls of Whiteflies in your Greenhouse?

The existence of greenhouse whitefly is always bane , especially if you are growing poinsettias. As soon as you are getting poinsettias you can expect whiteflies to come along with them. The best thing is that this creature is a very predictable pest so managing them can be planned properly. Greenhouse whiteflies can dangerously attack down all the plants. Searching for the proper organic treatment for whiteflies is necessary.

Know your pest, the dangerous whiteflies

Most commonly, you will find whiteflies on vegetable plants. The common whiteflies found in greenhouses include the greenhouse whitefly (Trialeurodes vaporariorum) and the sweet potato whitefly (Bemisia tabaci). Greenhouse whitefly damages leaves initially before sucking the fluid present in the whole plant. They look to lay eggs on the undersides of the leaves of the plants they attack. They are tiny crawlers and hatch the eggs underneath the leaves to settle there. Then they moult into immobile nymphs. Their presence leads to leaves having yellow or green chlorotic spots. These spots appear on the tops while the nymphs are sucking fluid at the bottom of the leaves. Have you checked other phloem feeders? They produce honeydew that usually leaves shiny patches on leaves. It helps the black sooty mold to grow. The same happens when these whiteflies also attack.

Whitefly biological control

Organic treatment for whiteflies is always needed. While doing whitefly pest management, one needs to understand the importance. Generally, you can monitor the whiteflies and keep scouting to catch the attack in the early stage. Sometimes, you can have biological treatment as soon as the pests are found, or you can also prefer to use it as a preventive method.

Encarsia and Eretmocerus parasitoids

These two parasitoids are ubiquitous biological control agents. These tiny creatures lay eggs inside or just beneath whitefly nymphs. Then, these tiny wasp larvae feed and develop within the nymphs of the whiteflies and come up as adults to kill the nymphs. The most important thing you should keep in mind is that Eretmocerus is the specialist for the sweet potato whitefly, while Encarsia is the specialist for the greenhouse whitefly. These parasitoids are usually sold as pupae within the whitefly pupae that are glued to the cardboard strips and hung on plants. These parasitoids are typically used as a preferred organic solution for whitefly attacks.

Amblyseius swirskii

Amblyseius swirskii is a predatory mite. It is another biological control agent that attacks whiteflies on vegetable plants. It complements parasitoids in poinsettia production usually. This tiny predator does not only eat whitefly eggs and small nymphs but also attacks the thrips. These are strongly known for attacking the whiteflies, but they do not usually fly. As the flying stuff goes against them, a farmer doing greenhouse farming who wants to get rid of whiteflies should distribute it in small sachets to all the plants.

Delphastus Catalina

Have you seen the tiny black lady beetles? Their scientific name is Delhastus catalinae. They are just less than 2 mm long and are known to feed voraciously on whitefly eggs and nymphs. If you are looking to know how to get rid of whiteflies naturally, then these beetles can be the choice you should look at. The major drawback is that these beetles want to eat so many whitefly eggs and nymphs to survive that it is hard to sustain them. If your garden has too many whiteflies, then only these black lady beetles are optimal for you.

Beauveria bassiana

Pathogens like Beauveria bassiana are known to be the best biological control options for organic whitefly management. Spray them in the garden near the roots and leaves of the plants like an insecticide. The best thing about this pathogen is that it does not just kill the whiteflies but also kills thrips, mites, and aphids easily. They complement the complete whitefly pest management program well. It also strengthens the soil for future gardening purposes. It can also be used as a preventive measure very easily.
