국문 초록 (Abstract)

감나무애응애의 생활사를 27℃에서 조사한 결과, 난기간은 11.1일, 유충기간 6.9일, 전약충기간 5.6일, 후약충기간 8.0일이었다. 성충수명에서 산란전기간은 5.3일, 산란기간 18.3일, 산란후기간은 14.3일이었다. 평균 산란수는 15.4개, 성비는 1.2 : 1(암 : 수)이었다. 감나무애응애의 내적자연증가율은 0.0484, 개체군 배가기간은 14.3로 나타났다.
감나무애응애의 혼합태에 대한 약제효과 시험에서 azocyclotin 25WP, chinomethionat 25WP의 효과가 매우 우수하였으며, flufenoxuron 5DC, tetradifon+pirimiphosmethyl 33EC, hexythiazox 10WP, abamectin 1.8EC의 약효도 기대되었다.

The life history of Tenuipalpus zhizhilashviliae was investigated at 27℃. The average durations of egg, larval, protonymphal and deutonymphal stages were 11.1 , 6.9, 5.6 and 8.0 days, respectively. The periods of preoviposition, oviposition and postoviposition were 5.3, 18.3 and 14.3 days, respectively. The average eggs laid by female was 15.4 and the sex-ratio was 1.2 : 1(female : male). The intrinsic rate of increase and population doubling time of Tenuipalpus zhizhilashviliae were 0.0484 and 14.3 days, respectively.
As a result of chemical control, azocyclotin 25WP and chinomethionat 25WP were good effective against mixed developmental stages of Tenuipalpus zhizhilashviliae, followed by flufenoxuron 5DC, tetradifon+pirimiphosmethyl 33EC, hexythiazox 10WP, and abamectin 1.8EC.
