열대 관상식물, 당종려나무를 가해하는 가루깍지벌레에 대한 신규 토착천적(Chrysoperla nipponensis (Okamoto))의 적용가능성 진단

다국어 초록 (Multilingual Abstract)

Biological control of Pseudococcus comstocki (Kuwana) with new indigenous natural enemy (Chrysoperla nipponensis (Okamoto)) was carried out on tropical plant (Trachycarpus fortunei (Hook)) from May to July in 2013. Control experiments were conducted at Tropical Plant Resources Research Center of Korea National Arboretum, Pocheon, Korea. Chrysoperla nipponensis was released once (20 larvae/m2) to control Pseudococcus comstocki on 11st May in 2013. We investigated the density of leaf-feeding P. comstocki at intervals of approximately 7 days after introducing their natural enemy, C. nipponensis. The densities of P. comstocki were suppressed 22.4% (after 4 weeks) and 8.2% (after 6 weeks) after introducing C. nipponensis.
