Abstract

Scales have attacked 9 hectares of apple land spread in 8 villages of Bumiaji sub-district such as Giripurno village, Tulungrejo village, Pandanrejo village, Sumbergondo village, Bulukerto village, Punten village, Gunungsari village, and Bumiaji village. This pest is a perennial pest on apple crops and difficult to control. The current way of control has not been able to overcome this pest problem. Therefore, research is needed to get effective control technology and easy to implement. The use of colour traps in addition to control needs, and also expected to needs of monitoring and identification of existing problems that make this pest difficult to control. This research was conducted to find out the effect of colour trap to community structure at Junggo, Tulungrejo Village, Bumiaji Sub-district, Batu City. Colour traps are fitted with 10 types of treatment colour with 3 replication. The observational data were analyzed by using community test. The results showed that the community analysis on the colour trap indicating that the index of diversity (H') and the dominance index (C) all treatments and families were small but the uniformity index (E) belonged to the stable community was owned by treatment B8 white colour with height 1.5m) and B9 (clear colour with height 1m). The largest dominant index (C) data of Diaspididae family (scales) is owned by B7 treatment (white colour with height 1m) of 0.18. The natural enemy species of scales found on apple plants is Encarsia strenua (silvestri) : Famili Aphelinidae.Key Words: Apple, Colour trap, Scales

Abstract

Abstrak Tikus sawah merupakan hama utama dan penyebab kerugian terbesar pada tanaman padi di Indonesia. Cara pengendalian hama yang ada sampai saat ini belum sepenuhnya dapat mengatasi masalah hama tikus. Oleh karena itu diperlukan penelitian untuk mendapatkan teknologi pengendalian yang efektif dan mudah dilaksanakan dengan menggunakan gelombang ultrasonik jangkrik. Penelitian ini dilakukan untuk mengetahui pengaruh gelombang ultrasonik jangkrik terhadap pola perilaku makan pasif dan gerak pasif tikus. Gelombang ultrasonik jangkrik dipaparkan langsung terhadap tikus sawah dan diamati melalui pola perilaku makan pasif dan gerak pasif yang ditunjukkan oleh tikus sawah. Data  hasil  pengamatan  pola  perilaku  makan  pasif  dan  gerak pasif tikus dianalisis dengan analisis  variansi rancangan faktorial. Faktor yang diamati meliputi frekuensi, jarak sumber, dan lama pemaparan gelombang ultrasonik jangkrik serta  kombinasinya. Frekuensi gelombang ultrasonik jangkrik pada jarak 100 cm dan lama pemaparan 45-60 menit dapat menimbulkan  perubahan  pola perilaku makan pasif dan gerak pasif  tikus. Perubahan tersebut terjadi akibat efek termal, efek kavitasi dan efek  mekanik  yang  terjadi  pada  struktur  jaringan sel  tikus. Kata kunci : gelombang ultrasonik, jangkrik, tikus sawah Abstract Over the last decade, paddy field rat cases in Indonesia still become problem cultivation rice plant. The control method be present now is not yet get exceed  rat wet rice pest. Because that, need straight away research for get technology control that effective and easy to applicate. The control rat wet rice pest with cricket ultrasonic waves we hope that can become alternative that problem solving. The aim from this research is for knowing the influence of cricket ultrasonic waves toward the passive feeding and passive motion rat wet rice field. Cricket ultrasonic waves direct flat to rat rice pest. The data on the observation of response and change of behavior patterns that covered the patterns of passive movement and of passive feeding of  rat wet rice field brought  about  by  ultrasonic  wave  disturbances were analyzed and employed to determine which parameter  were the most dominant among variations exposure distance  and  exposure time of the ultrasonic waves. The result of research gave significant differences (P<0.05) of the effect of ultrasonic wave frequency, source distance and exposure time. At cricket frequency, it  already  gave  effective impact  toward  behavior  patterns that covered  the  patterns  of  passive  feeding  and  passive  movement  of  the migratory locusts. At this cricket frequency, with exposure time of 45 to 60 minute at 100 cm  distance  it  has  already effective impact  toward the  behavior patterns  of rat wet rice field compared  to the change of  source distance longer  than 100 cm at other time too towards passive feeding and passive motion pattern of rat wet rice field.
