스트레스 음파 처리에 따른 아메리카잎굴파리 [Liriomyza trifolii]의 생리 변화와 프로테오믹 분석


Effects of Sound Stress on Physiological Processes of the American Leafminer, Liriomyza trifolii, and Proteomic Analysis

  This study investigated the adverse effects of sound treatment on physiological processes of the American leafminer, Liriomyza trifolii, during several developmental stages. Larval feeding activity was analyzed by measuring feeding tunnel length. It was significantly suppressed by sound treatment (5,000 Hz, 95 dB). Sound treatment delayed the pupal period at 315 - 5,000 Hz and prevented adult emergence at 1,000 - 5,000 Hz. Female oviposition was also inhibited by the stress sound treatments. However, phototactic adult movement was not affected by sound treatment. Pupae treated with 5,000 Hz showed marked changes in protein pattems analyzed by two dimensional electrophoresis. MALDI-TOF analysis of specific protein spots indicated that trafficking protein particle complex I, triosephosphate isomerase, hypothetical protein TcasGA2_TC013388, polycystin-2, paraneoplastic neuronal antigen MAl, and tropomyosin I (isoform M) were predicted in the control insects and disappeared in the insects treated with sound. By contrast, DOCK9, cytoskeletal keratin II, and F0F1-ATP synthase beta subunit were predicted only in the sound-treated insects. Furthermore, stress sound significantly increased the susceptibility of L. trifolii to insecticides. These results suggest that physiological processes of L. trifolii are altered by sound stress, which may be exploited to develop a novel physical control tactic against L. trifolii.
