非洲菊斑潛蠅繁殖時同齡幼蟲與成蟲在菜豆本葉上之種內競爭

Abstract

非洲菊斑潛蠅［Liriomyza trifolii（Burgess）］（Diptera：Agromyzidae）為世界性重要之園藝與蔬菜作物害蟲，進行該蠅生物防治與藥劑防治研究之前，必先建立其適當繁殖方法。本文利用菜豆（Phaseolus vulgaris var. communis Aeschers）苗飼育非洲菊斑潛蠅，希冀瞭解在菜豆苗本葉（primary leaf）不同葉寬下，該蠅同齡幼蟲與成蠅各在不同密度繁殖時之種內競爭，以提供該蠅及其寄生蜂較優之繁殖方法。 The agromyzid leafminer, Liriomyza trifolii (Burgess), is a major pest of vegetables and ornamentals throughout the world. For its biological and chemical control studies, the suitable rearing methods of this leafminer must be established. This study investigated the intraspecific competition among same-aged larvae and adults in three width grades of field bean primary leaves (Phaseolus vulgaris var.
