Abstract
Some experiments were conducted to evaluate the aphidivorous activity of coccinellid beetle, Harmania axyridis Pallas. Experiments were carried out using with laboratory reared beetles and two aphid species(Aphis gossypii and Myzus persicae). Factors referred in the study of aphidivorous activity were the age of beetle, aphid species, temperatreu and illumination time. The aphidivorous activity was greatly different in relation to aphid species, developmental stages of the beetle, and the temperature. The 3rd and 4th instar larvae consumed more aphids than the 1st and 2nd instar larvae. Though the beetles consumed more number of cotton aphid, total weight of aphids consumed the more or less the same. Aphidivorous activity of the 1st to 4th instar larvae increased with a rise in temperature and adult activity was relativel high at
진딧물 포식성(捕食性) 천적(天敵) 무당벌레(Harmonia axyridis Palls) 의 포식능력(捕食能力)을 평가(評價)하고 진딧물 포식능력(捕食能力)에 미치는 진딧물의 종(種), 무당벌레의 영기별(齡期別), 온도별(溫度別) 및 광조사조건(光照射條件)의 영향(影響)을 비교((比較) 검토(檢討)한 결과(結果)는 다음과 같다. 1. 무당벌레의 진딧물 포식능력(捕食能力)은 유충(幼蟲)의 영기(齡期)가 진행(進行)됨에 따라 크게 증가(增加)하였는데,
