PRODUCT AND APPLICATION: 

Feltiella is delivered in a biodegradable tray from which at least 250 adult midges will emerge. The product is shipped with a bottle of a natural stimulant spray called Ovistim, which can be applied to foliage to encourage Feltiella to lay more eggs in a desired area. Feltiella requires little effort to use; it will spread fast throughout the greenhouse thanks to its flying ability. Open the release unit and hang it close to the spider mite hotspot.  Protect it from direct sunlight and water. Apply Ovistim to plants around areas of infestation. Although Feltiella is less sensitive to low humidity than other predators, high humidity will make it easier to get established in the crop. Introduce the beneficials as soon as possible after receipt. If storage is necessary, keep them at 8–10 °C (46–50 °F).

The cotton aphid (Aphis gossypii)
The cotton aphid (Aphis gossypii) is a 0.9-1.8 mm small, round aphid with typical black spiracles. The colour varies from light yellow to dark-green, or sometimes almost black. It has a short cauda, no head front knobs, and antennae shorter than the body.

The cotton aphid originates from warmer regions where it is a pest on cotton and Cucurbitaceae. Thanks to the warm climate in greenhouses it can also survive northern winters. The cotton aphid is mainly a pest on greenhouse vegetables such as cucumber and melon, and on ornamentals such as chrysanthemum andhibiscus. Greenhouse strains do not change their host plant. After hibernation in the greenhouse this aphid can become a pest early in spring.

More than other aphid species, populations of cotton aphids can grow very fast. There exist several strains of cotton aphids, each with a specific preference for a certain host and resistance against pesticides.

ABOUT: Feltiella acarisuga is a predatory gall midge for the control of spider mites. Adults are excellent flyers and will easily spread throughout the entire crop. Adult Feltiella is about 2 mm long and is pink-brown. The eggs are yellowish and 0.25 mm long. The larvae are creamy-yellow-brown and 0.25 -2 mm long. The pupae can be found inside the white cocoons along the veins of the leaves. The female adult lays her eggs inside spider mite colonies and the larvae begin to prey voraciously on the spider mites immediately after hatching. Feltiella is most effective if introduced curatively, around spider mite hot spots, rather than preventatively.
