中文摘要 | 在本所73/74至82/83共10個年期之春植調查田,每年期均自甘蔗萌芽整齊採收前為止,每兩週一次在10畦固定與10畦變動調查畦合計208 面積上,自最基部割取每支枯心,縱剖後辨認枯心與被害節間之種類,採集其內之蔗螟幼蟲與蛹。結果在203次調查中,自6,218支螟害枯心採獲2,062隻5種蔗螟之幼蟲與蛹,採獲率為33.2%。以二點螟之1,461隻最多,佔採獲蟲數之70.9%,其次為白螟之376隻,然後依序為條螟之113隻,黃螟之77隻與紫螟之35隻。自未形成節間之幼蔗上採獲之白螟、二點螟與紫螟幼蟲與蛹數,各佔其全年期採獲數之82.1%以上;相反的,77.9%之條螟幼蟲與蛹係在七月以後已形成節間之枯心上採到;自未形成節間之枯心採獲之黃螟幼蟲與蛹數佔48.1%,其餘之51.9%則自已具節間之枯心上採獲。本文並討論每種蔗螟幼蟲與蛹周年採獲數之消長情形。 |
英文摘要 | The borer larvae and pupae were recovered from dead hearts collected every 2 weeks from a 208 M area in 1984/85 to 1993/94 spring cane at Taiwan Sugar Research Institute experimental farm. In 203 surveys, 2,062 larvae and pupae were obtained from 6,218 dead hearts caused by 5 species of borers. Among them, 1,278 larvae and 183 pupae were Chilotraea infuscatella, 374 larvae and 2 pupae were Scirpophaga nivella, 110 larvae and 3 pupae were Proceras venosatus, 69 larvae and 8 pupae were Argyroploce schistaceana, and 34 larvae and one pupa were Sesamia inferens. More than 82% of the larvae and pupae of S. nivella, C. infuscatella, and S. inferens were obtained from dead hearts of young tillers, while 77.9% of the P. venosatus were collected from dead hearts of growing cane with internodes, which appeared after July. In the case of A. schistaceana, 48.1% of the collection were from damaged stems without internodes and 51.9% from dead stems with internodes. The collection of larvae and pupae in the entire crop year is discussed for each borer species. |
