摘要

於5～30℃六種定溫下，桃蚜(Myzus persicae(Sulzer))各齡若蚜之發育時間在蘿蔔及馬鈴薯上有顯著差異，皆以5℃為最長，25℃為最短。成蟲壽命以5℃時最長(在蘿蔔及馬鈴薯上分別為56.9天及29.7天)，而以30℃時最短(分別為7.6天及6.2天)。自5℃始，生殖力隨溫度增高而加大，在蘿蔔上之生殖力以22℃時達到巔峯(66.0若蚜/雌蚜)，在馬鈴薯上則以15℃時最大(59.5若蚜/雌蚜)。顛峯之後，生殖力隨溫度升高而降減，以30℃時最低(在蘿蔔上0.5若蚜/雌蚜，在馬鈴薯上0.44若蚜/雌蚜)。以直線迴歸求得之總積溫在蘿蔔上為152.70°D，在馬鈴薯上為117.66°D，經三次多項式迴歸分析得知，在蘿蔔上之發育適溫為22～25℃，在馬鈴薯上為25～27℃。

Development times of each stadium in Myzus persicae (Sulzer) reared on radish and potato at six constant temperatures varying from 5-30°C were significantly different. Development time was longest at 5°C and shortest at 25°C. The greatest adult longevity were observed on both radish and potato at 5°C, which were 56.9 and 29.7 days, and the shortest at 30°C, which w e 7.6 and 6.2 days, respectively. Fecundity increased proportionally with temperature above 5°C, with maxima of 66.0 offsprings/female at 22°C and 59.5 offsprings/female at 15°C, when reared on radish and potato, respectively. Reproduction began decreased at temperatures over 22°C and 15°C on radish and potato, respectively. Among the temperatures tested, the lowest fecundity was observed at 30°C, 0.44 and 0.5 offsprings/female, on radish and potato, respectively. The thermal summation on radish (152.70°D) was greater than that on potato (117.66°D). However, the thrid order polynomial regression curve gave more satisfactory conclusions than linear equation in this study, indicating an optimal temperature for rapid development of 22-25°C on radish and 25-27°C on potato.
