摘要

於台灣高、屏地區玉荷苞荔枝主要產地調查害蟲種類，共發現22種害蟲及葉蟎與蝸牛各一種，其中開花期以毛管蚜(Greenidea mangiferae)發生最多，危害率爲15.14-22.47%，平均18.52%，結果期以荔枝細蛾(Conopomorpha sinensis)及東方果實蠅(Bactrocera dorsalis)爲害果實最多，前者爲害植株上鮮果率爲9.74-20.76%，平均12.75%，落果被害率64.93-85.13%，平均73.24%，後者爲害果率爲6.45-12.15%，平均9.51%；嫩葉生長期則以捲葉蛾與荔枝尖細蛾(C. litchielle)發生較多，其爲害新芽及幼葉率分別爲8.23-35.27%，平均21.27%及16.17-46.75%，平均25.88%，老葉則以黃綠綿介殼蟲(Chloropulvinaria psidii)發生較多，危害葉率5.28-18.69%，平均9.52%。比較不同材質作果實防蟲套袋試驗結果，以套白色紙袋防蟲效果最佳，採收前10天及當天調查對荔枝細蛾之防治率分別爲88.44%及100%，對東方果實蠅防治率均爲100%。

Surveys of insects and other pests on yuh-heh-bau litchi were carried out from 2002 to 2007 in southern Taiwan. A total of 22 species of insects, one species of mite and one species of snail were found in southern Taiwan. Among them, the mango aphid (Greenidea mangiferae), litchi fruit borer (Conopomorpha sinensis), leaf borer (C. litchielle), cottony mealybug (Chloropulvinaria psidii), leaf roller (Ehola celligera) and oriental fruit fly (Bactrocera dorsalis) were considered of economic importance. This report described the symptom of their injuries and percentages of infestation. Paper bag used for wrapping fruit was more effective than nylon net to protect litchi from the infestation of litchi fruit borer and oriental fruit fly.
