It preys on all species and stages of whitefly but prefers eggs and nymphs. Delphastus pusillus is considered an effective biological control agent for whiteflies because of its high prey consumption rates, long adult survival, and high reproduction rates.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplication Rate Recommendations for Delphastus pusillu:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003ePreventative:\u003cspan\u003e \u003c\/span\u003e\u003c\/b\u003e1-2 beetles per square foot or at least 100 adults per whitefly “hot spot”, or 10 adults per infested plant, weekly, for 3-4 weeks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModerate Infestation:\u003c\/strong\u003e\u003cspan\u003e 2-4 beetles per square foot or 500 adults per whitefly “hot spot”, or 1-2 adults per 10 square feet, weekly, for 4 weeks\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy Infestation:\u003c\/strong\u003e 4-6 beetles per square foot or 500 adults per whitefly “hot spot”, or 3-4 adults per 10 square feet, weekly, until established in all infested areas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eHow-To Use\u003cspan data-mce-fragment=\"1\"\u003e Delphastus pusillu hesperus\u003c\/span\u003e For Best Results:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eStore them at 50-59 °F (10-15 °C).\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRelease them in the early morning or late evening.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eOpen the container, and gently shake beetles onto foliage close to whitefly infestations.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePlace the container upright among plants to release the remaining beetles.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDelphastus pusillus is most effective at high whitefly densities. Since adult female beetles must feed on over 200 eggs per day in order to reproduce, it may be of limited benefit in greenhouses where whitefly populations are low. Both adult and larval beetles avoid feeding on whitefly nymphs parasitized by wasps such as Encarsia formosa and Eretmocerus eremicus when the wasps are in the later stages of development\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures \u0026amp; Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh prey consumption rates\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLong adult survival\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHigh reproduction rates\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eEffective biological control agent for whiteflies\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eUsed to control whiteflies in tropical and semi-tropical plants as well as commercial greenhouses\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThe predators avoid feeding on parasitized whiteflies, therefore is compatible with whitefly parasites such as Encarsia and Eretmocerus species\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTends to feed in high-density whitefly populations, while parasites do best at lower densities\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePrefer feeding on whitefly eggs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eItem Numbers:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eDPUS1 \u003c\/span\u003e\u003c\/strong\u003e- 30ml vial\u003cstrong\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e- 100 adults - filter paper\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDPUS1K\u003c\/strong\u003e - 250ml bottle - 1K adults - filter paper\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0266\/5283\/5919\/files\/GHA-Delphastus-pusillus-2_480x480.jpg?v=1694805811\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0266\/5283\/5919\/files\/GHA-Delphastus-pusillus-1_480x480.jpg?v=1694805826\"\u003e\u003c\/p\u003e\n\u003cstyle\u003e\u003c!--\n.responsive-iframe-container {\n        position: relative;\n        overflow: hidden;\n        padding-top: 56.25%; \/* 16:9 Aspect Ratio (divide 9 by 16 = 0.5625) *\/\n        width: 100%; \/* responsiveness *\/\n    }\n\n    .responsive-iframe-container iframe {\n        position: absolute;\n        top: 0;\n        left: 0;\n        width: 100%;\n        height: 100%;\n        border: 0;\n    }\n--\u003e\u003c\/style\u003e\n\u003cdiv class=\"responsive-iframe-container\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/J2nhwHIcvq0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e","brand":"Growers House Auto","offers":[{"title":"30ml vial - 100 adults - filter paper","offer_id":45090265202824,"sku":"DPUS1","price":37.33,"currency_code":"USD","in_stock":true},{"title":"250ml bottle - 1K adults - filter paper","offer_id":45090265235592,"sku":"DPUS1K","price":352.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0717\/4648\/6408\/files\/Growers-House-Auto-4_8babb280-7a02-4194-b1b8-77dd1a1e0a18.png?v=1777600710","url":"https:\/\/www.natesgardensupply.com\/products\/growershouse-delphastus-pusillus-control-whiteflies","provider":"Nate's Garden Supply","version":"1.0","type":"link"}
