乌干达甘薯粉虱数量的季节变化及其对甘薯褪绿矮化病毒和甘薯病毒病发病的影响
摘要
Variation in whitefly numbers on sweetpotato and incidence of sweetpotato chlorotic stunt virus (SPCSV) and sweetpotato virus disease (SPVD) were studied. There were significant differences ( P < 0.05) in monthly whitefly numbers. Overall, whitefly populations increased with temperature and decreased with rainfall within a month. Peak whitefly populations occurred in the hot dry season, but whitefly numbers were generally greatest on crops 3- 4 months old. Incidence of SPVD increased with crop age. Planting date only affected incidence of SPCSV in the second season, and whitefly population was not closely related to SPCSV incidence.

研究了甘薯粉虱数量和甘薯褪绿特异病毒(SPCSV)和甘薯病毒病(SPVD)发病率的变化。每月粉虱数量差异显着(P 0.05)。总体来说,粉虱种群随温度升高,降雨量在一个月内下降。高温白粉虱种群发生在炎热干燥的季节,但在3-4个月大的作物上,粉虱的数量通常最多。随着作物年龄的增长,SPVD的发生率增加。种植日期仅影响第二季SPCSV的发生,而粉虱种群与SPCSV的发生率无关。
