These small, almost invisible insects (approx. 1 mm) are specialists in parasitizing whitefly larvae and stopping the infestation exactly where it starts.\u003c\/p\u003e\n\u003cp\u003eThe product is delivered as cards with pupae, which are hung on the plants. From there, the parasitic wasps hatch gradually during the first week and fly out to find whitefly larvae. Once they have found their prey, they lay an egg in the larva, which dies and later turns black – a clear sign that the control is underway. Over time, new parasitic wasps hatch from the black larvae and continue the work, keeping the population down.\u003c\/p\u003e\n\u003ch3\u003eSigns of whiteflies\u003c\/h3\u003e\n\u003cp\u003eWhiteflies are small plant-sucking insects that can cause particular problems on houseplants and in the greenhouse. The adult whiteflies are only a few millimeters in size and have white, powdery wings. They typically stay on the \u003cstrong\u003eunderside of the leaves\u003c\/strong\u003e, where eggs and larvae are also found.\u003c\/p\u003e\n\u003cp\u003eA very characteristic sign of whiteflies is the small \u003cstrong\u003ecloud of white insects that fly up\u003c\/strong\u003e when the plant is touched or the leaves are shaken gently. After a short time, the adult whiteflies usually settle back on the plants.\u003c\/p\u003e\n\u003cp\u003eWhiteflies suck plant sap, and with major infestations, the plants can become weakened. The leaves may begin to \u003cstrong\u003eyellow, look dull and fall off\u003c\/strong\u003e, while the plant's growth is inhibited.\u003c\/p\u003e\n\u003cp\u003eLike aphids and mealybugs, whiteflies secrete \u003cstrong\u003ehoneydew\u003c\/strong\u003e. Sticky leaves can therefore be one of the first signs of an infestation. Sooty mold can subsequently develop on the honeydew, forming a dark coating on the leaves.\u003c\/p\u003e\n\u003cp\u003eIt is also important to examine the \u003cstrong\u003eunderside of the leaves\u003c\/strong\u003e. Here you can find the adult whiteflies as well as the much less conspicuous eggs and larval stages.
