Abstract

In Korea, six mealybug species have been reported on pears. This study investigated the occurrence of mealybugs in 19 pear orchards from 2013 to 2014. Two species, Crisicoccus matsumotoi Siraiwa (Hemiptera: Pseudococcidae) and Pseudococcus comstocki Kuwana were mainly found. The dominant species was C. matsumotoi identified on 73% of infested fruit. Toxicities of 14 registered insecticides (Buprofezin+Acetamiprid EC, Buprofezin+Amitraz EC, Buprofezin+Clothianidin SC, Buprofezin+Dinotefuran WP, Buprofezin+Etofenprox WG, Buprofezin+Thiacloprid SC, Buprofezin+Thiamethoxam SC, Benfuracarb WG, Acetamiprid WP, Clothianidin SC, Dinotefuran WG, Thiacloprid SC, Thiamethoxam WG, Sulfoxaflor SC) commonly used to control P. comstocki were evaluated to C. matsumotoi nymphs and adults at the recommended concentration. As a results, all insecticides exhibited strong insecticidal activity with 100% mortality of both nymphs and adults. These results indicate that the 14 insecticides can be used in control for C. matsumotoi in field.

국내에서 배에 발생하는 가루깍지벌레는 6종이 보고되어 있다. 본 연구에서는 배 과원 19곳에서 2년간(2013년, 2014년) 가루깍지벌레류의 분포를 조사하였다. 그 결과, 버들가루깍지벌레와 가루깍지벌레가 주로 발견이 되었다. 우점종은 73%를 차지한 버들가루깍지벌레였다. 배 가루깍지벌레에 등록된 14개 약제(Buprofezin+Acetamiprid EC, Buprofezin+Amitraz EC, Buprofezin+Clothianidin SC, Buprofezin+Dinotefuran WP, Buprofezin+Etofenprox WG, Buprofezin+Thiacloprid SC, Buprofezin+Thiamethoxam SC, Benfuracarb WG, Acetamiprid WP, Clothianidin SC, Dinotefuran WG, Thiacloprid SC, Thiamethoxam WG, Sulfoxaflor SC)를 대상으로 버들가루깍지벌레의 방제가 가능한지 약충과 성충에 추천농도로 처리하였다. 그 결과 14개 모든 약제가 100%의 높은 살충활성을 나타내었다. 따라서 이들 약제는 버들가루깍지벌레의 방제에도 이용될 수 있을 것으로 생각된다.
