감귤해충 종합방제 확립을 위한 기초자료를 얻고저 제주도 서귀포에서 1973-1976년까지 4년간 실시한 결과 다음과 같은 결과를 얻었다. 1. 귤응애는 7철 중순에서 8철 중순 사이에 11회의 큰 peak를 나타냈다. 2. 한편 관행살포구에서는 7,8월뿐 아니라 9-11월에도 높은 밀도를 나타냈다. 3. 귤응애의 천적으로 Oligota yasumatsui K., Anysits baccarum L., Hemerobiid sp. Semidalis albate E., Orius sp., Agistemus terminalis Q., 무당벌레류 3종 포식응애 1종등 10종이 발견되었다. 4. 귤응애의 년도별 발생경향을 보며 무살포구에서는 매년 감소하는 경향이고 관행살포구에서는 계속 증가하는 경향이었다. 5. 살균제로서 석회볼드액과 동수화제 처리구는 귤응애밀도가 높았으나 항생제인 Streptomycin은 낮은밀도였다.
Experiments were conducted to study the integrated control of one of the major pests of citrus, the citrus red mite, Panonychus citri (McGregor). Studies were conducted in Seogwipo, Cheju Island, 1973-1976. Results obtained were: 1. The major peak of citrus red mite occurrence was mid-July to mid-August. 2. Standard field populations of citrus red mite were also high in September, October, and November. 3. A total of 10 species of natural enemies of citrus red mite were found. These included; Oligota yasumatusi Kistner, Anystis baccarum L., Hemerobiid sp., Semidalis albate E., Orius sp., Agistemus terminalis Q., 3 species of lady beetles (Coccinellidae), and one unidentified species of predacious mite. 4. Annual occurrence of citrus med mite tended to decrease in unsprayed fields, but increased in fields receiving standard treatments. 5. With fungicides, there was an increase in mite populations associated with use of Bordeaux mixture and copperpowder sprays. Streptomycin, however, did not effect on increase in mite numbers.
