  本試驗主要進行臺南地區水稻稻細蟎發生調查與防治研究。水稻稻細蟎自一期作末期開始出現於葉鞘內,平均密度為每分蘗2.3與3.2隻。二期作水稻之稻細蟎於抽穗前開始發生,密度於抽穗後四週達每分蘗141.0隻。二期再生稻田於整個生育時期皆可觀察到稻細蟎,乳熟期達513.3隻每分蘗。7鄉鎮36處水稻田之調查結果顯示,稻細蟎在臺南地區一期作收獲後稻樁上發生率為100%。藥劑試驗以10%芬殺蟎乳劑1000倍效果最佳,死亡率達99.1%,1%密滅汀乳劑1500倍次之,為89.0%。粒劑試驗以4%培丹、10%托福松、3%加保扶防治效果較佳,防治率分別為96.1%、91.3%、90.2%。

Study on Occurrence of the Panicle Rice Mite, Steneotarsonemus spinki Smiley
in Tainan District and its Control

Chun-Chun Chang

Abstract

   Survey on the 2 rice fields revealed that panicle rice mite Steneotarsonemus spinki Smiley was first observed in the leaf sheath in late growing stage of the 1st crop. Average mite numbers were 2.3 and 3.2 mites per tiller, respectively. In the 2nd crop, mite population of transplant rice field was observed before heading stage and density reached to highest level 4 weeks after heading with an average number of 141.0 mites per tiller. In the ratoon rice field, mite can be observed in all growth stage. The population increased to highest level at milky stage with an average number of 513.3 mites per tiller. Survey on 36 rice fields of 7 townships revealed that the 100% of panicle rice mite occurrence observed in the ratoon rice after 1st crop. Screening of miticides tested that 1000 dilution of 10% fenazaquin was the best with 99.1% of mortality followed by 1500 dilution of 1% milbemectin with 89.0% mortality. Granule tests indicated that 4% cartap, 10% terbufos, and 3% carbofuran were promising with 96.1%, 91.3% and 90.2% of mortality, respectively.
