The female lays her eggs inside developing whitefly nymphs, and the parasitized nymph turns a darker golden color as the wasp develops inside. These hanger cards deliver the pupae at 100 per card, ready to separate and hang where whitefly are building.

It can also sting and host-feed on nymphs without laying an egg, drinking the pest’s fluids for nutrition. It works best in a window of 68–77°F with relative humidity of 70% or less, and needs whitefly nymphs present to complete its life cycle. It pairs well with \u003cem\u003eEncarsia formosa\u003c\/em\u003e when both greenhouse and silverleaf whitefly are present.\u003c\/p\u003e\n\n\u003ch2\u003eRelease Rates\u003c\/h2\u003e\n\u003cdiv class=\"gm-table-wrap\"\u003e\n\u003ctable class=\"gm-release-table\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eClassification\u003c\/th\u003e\n\u003cth\u003eRelease Information\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLow\u003c\/td\u003e\n\u003ctd\u003e0.5 to 2 per 10 sq. ft.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMedium\u003c\/td\u003e\n\u003ctd\u003e5 to 20 per 10 sq. ft.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cp style=\"text-align: left;\"\u003ePreventive releases may need to be made weekly instead of bi-weekly if the crop is a “whitefly magnet.”\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cstrong\u003eCannabis Alert:\u003c\/strong\u003e Release rate suggestions on these pages are usually not sufficient for cannabis growers.

If that is not possible, avoid the hot, dry times of day. Until release, keep the strips of cards in a cool, dark space so the wasps can maximize their remaining development time.\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cstrong\u003eRelease method:\u003c\/strong\u003e Separate the cards at the perforations by gently folding them back and forth — don’t tear them, which can knock the delicate pupae loose, and avoid touching the pupae. Hang the cards within the canopy, protected from sun and water, distributed evenly through the crop or next to the pest’s preferred hosts. Place them in shaded areas and leave them undisturbed for about 21 days to ensure emergence. Blister packs are released the same way, with the plastic bubble giving extra protection in overhead-watered crops.\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cstrong\u003eStorage:\u003c\/strong\u003e Do not cold store. It is best to apply the parasites as soon as possible upon receipt. If storage is unavoidable, keep them between 45–50°F in the dark, up to 18 hours after receipt.\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cstrong\u003eMonitoring:\u003c\/strong\u003e Parasitized whitefly nymphs take 10–14 days to start appearing and often show a wound where the ovipositor contacted them. For Eretmocerus, look closely inside the nymphs for developing larvae; parasitized nymphs are left with a round, submarine-style exit hole, whereas an emerged adult whitefly leaves a T-shaped slit.\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cstrong\u003eAdvisories:\u003c\/strong\u003e Yellow sticky cards will catch these adult wasps as they emerge, so removing yellow cards at the time of release is ideal.\u003c\/p\u003e\n\n\u003c\/div\u003e","brand":"Beneficial-Insectary","offers":[{"title":"Pack of 5,000","offer_id":46950952763548,"sku":"EE5","price":62.95,"currency_code":"USD","in_stock":true},{"title":"Pack of 10,000","offer_id":46950952796316,"sku":"EE10","price":121.95,"currency_code":"USD","in_stock":true},{"title":"Pack of 15,000","offer_id":46950952829084,"sku":"EE15","price":167.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/0403\/6764\/files\/ERETforce_whitefly_parasite_100_per_card_5_000__10_000__15_000_pack_of_5000.webp?v=1779310527","url":"https:\/\/greenmethods.com\/products\/eretmocerus-eremicus-whitefly-parasite-on-hanger-cards-10000","provider":"Green Methods","version":"1.0","type":"link"}
