Farmers’ practice describes releasing the predator Cryptolaemus montrouzieri, bred with support from local governmental advisors in Spain. Combined measures that strengthen predator performance can lower pest populations year after year. The approach involves farmer collaboration as insectary contributors, a 3–4 month breeding cycle, and inoculative field releases timed to the mealybug life stages (May–October).",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":40,"@type":76,"position":81},"https://docshare.wps.com/document/research-report/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/breeding-natural-enemies-successful-farmers-experiences/608298/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/breeding-natural-enemies-successful-farmers-experiences/608298.png","ImageObject",300,407,{"name":92,"@type":93},"Rhys","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-01","2026-10-17",true,{"@type":102,"interactionType":103,"userInteractionCount":24},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"Why do farmers release Cryptolaemus montrouzieri in Valencian citrus?","Question",{"text":112,"@type":113},"Mealybugs are a major problem in Valencian citriculture, aggravated by new invasive species.

The process consists of the following:  \no Germinating potatoes on the substrate (sand or peat) in the dark, at 22°C, with air renewal and regular watering for one month (Picture 1) .  \no The pest (Planococcus citri) is provided to them on fake pepper leaves, and they are released into the brood, which is then kept at 26°C for one month (Picture 2) .  \no The adults of the predator are introduced (35 days) . The predator is collected for three weeks. They are attracted to the point of light, and with food (a mixture of water, agar, honey and sugar), and collected manually (Picture 3)  \n• They are released in the plots at inoculative doses (2,000 adults/ha) . Release time: for Planococus citri (June), for Delottococcus aberiae (June to September), for Pulvinaria polygonata (May to October) . They are also released in other crops, such as persimmon and pomegranate (from June to September) .  \nPicture 1: Breeding room with potato sprouts.  \nPhoto: Deval, I.  \nPicture 2: Release of Panococcus citri in the  \nbreeding chambers.
