Advances in Mass Rearing of Chrysoperla carnea (Stephen) (Neuroptera: Chrysopidae) Ashfaq, Muhammad 106916 Nasreen, Abida 106917 Cheema, Ghulam Mustafa 106918 486 Chrysoperla carnea mass rearing larvae rearing in gelatin capsule newly designed adult rearing chamber Rearing techniques for Chrysoperla carnea Stephen (Chrysopidae: Neuroptera) have been improved to have its mass rearing in laboratory and to make releases in fields in a very simple and economical way. In this technique hard gelatin capsules (500 mg) were used for larval rearing. Out of 100 test capsules, 140 pupae were recovered by this technique. Of all 62 % of the test capsules contained single, two % capsules found without pupae. Adult emergence was found to be 99 % and none of the adult was deformed. Sixty seven mg of frozen eggs of Sitotroga cereallela per larva were offered in a single feed per capsule to complete its larval growth. A rectangular (35 x 20 x 35 cm) adult rearing chamber made of transparent plastic sheet with removable top was designed, to allow proper illumination and ventilation inside the chamber. Handling of the adult green lace wing i.e., Chrysoperla carnea (sanitation, cleaning, feeding and harvesting of eggs) in the newly designed rearing chamber proved very easy and it eliminated the use of vacuum sucker, anesthesia and chemicals like Sodium hypochlorite, Potassium hypochlorite etc. The eggs of C. carnea were harvested efficiently without initiation of diapause because of the microenvironment developed inside the cage with high relative humidity. journal article 鹿児島大学 Kagoshima University 2004-02-27 VoR application/pdf 南太平洋研究 2 24 47 53 South Pacific Study 09160752 AN10088628 https://ir.kagoshima-u.ac.jp/record/12989/files/AN10088628_v24n2_p47-53.pdf http://hdl.handle.net/10232/17380 https://ir.kagoshima-u.ac.jp/records/12989 eng open access
