摘要
采用田间网捕和室内外饲养等方法研究了关中大蒜根蛆葱地种蝇（葱蝇）Ｄｅｌｉａａｎｔｉｇｕａ（Ｍｅｉｇｅｎ）和灰地种蝇（种蝇）Ｄ．ｐｌａｔｕｒａ（Ｍｅｉｇｅｎ）的生活史与发生规律。优势种葱蝇一年发生３代，以围蛹在土中越冬。世代历期：室内３６．５～５９．５ｄ，田间３２～７４ｄ．其年生活史可分为春季为害、越夏、秋季为害和越冬４个阶段，以春季第１代为害最重，是造成大蒜减产的主要原因。混合种群为害程度受５ｃｍ土壤温度及含水量。
The life history and population dynamics of Delia antiqua (Meigen) and D.platura (Meigen) in garlic in Central Shaanxi were studied by means of indoor rearing and field survey. D.antiqua is the predominant species and has 3 generations a year,overwintering as puparium (coarctate pupa) in soil.The duration of each generation is 33.5￣66.7 d.The life history of D.antiqua could be divided into 4 periods:spring damaging,oversummering,autumn damaging and overwintering.The first generation causes the most serious damage to garlic in spring.Dynamics and damaging of the mixed population of the 2 species are deeply affected by the temperature and moisture of soil at 5cm deepth,by growth stage of garlic and by fertilizer.
