中文摘要 | 於1991-92,利用黃色水盤調查柑橘萎縮病毒媒介蚜蟲之季節消長,及蚜 蟲數量與環境因子(雨量、溫度)之關係。蚜蟲數量與雨量之間存在顯著負相關 (b=-0.52,p<0.05)。雨量最高(1991年6-7月:1992年7-8月)及最低(1991年1-4月;1992年 10-12月)之月份,分別與誘集之蚜蟲數量最少及最多相對應。病毒媒介蚜蟲(A. citricola,M. percicae及A. gossypii)之數量於1991年1月或2月份達到最高點之後,漸 減。病毒媒介蚜蟲約佔全部誘集蚜蟲數量之50。此外,本文尚探討了柑橘萎縮病 病毒媒介蚜蟲之綜合防治。 |
英文摘要 | This paper investigates the seasonal changes of the citrus tristezavirus(CTV)-vector aphids in 1991-92 using the yellow water tray and the relationships between aphid number and such environmental factors as rainfall andtemperature. A significant negative-correlation was found between the numberof aphids trapped and rainfall (b=-0.52, p< 0.05). The highest (June to July in1991; July to Aug. in 1992) and lowest (Jan. to Apr. in 1991; Oct. to Dec. in1992) amount of rainfall corresponded to those months in which the numberof aphids trapped were at a minimum and a maximum, respectively. The number of A. citricola, M. percicae and A. gossypii (CTV-vector aphids) trappedreached a maximum in Jan. or Feb. of 1991, and decreased afterwards. Theaverage percentage of CTV-vector aphids among all trapped individuals wasapproximately 50. In addition, integrated control of CTV- vector aphids is alsodiscussed. |
