1960年至1963年，在北卡罗来纳州的利兹角，用稀释的林丹杀幼虫剂将盐沼绿头马蝇的幼虫大量收集到割草地的表面，产生了900多只幼虫。其中包括T。黑条藓T. lineola F.，第三种形式在这里叫做T sp.3，是T. nigrovittatus。这些地块附近的沟渠银行和开放的盐沼产生了高达20.6幼虫每平方码，但所有死亡。对于生活史研究和饲养成人，干燥盐水线草丝网底架产生了许多未受污染的幼虫。T. sp. 3的收集挖掘与园艺手除草机的速率高达17幼虫每工时的沟渠银行栖息地。通过漂浮法收集每平方码产生7至11只幼虫，但对幼虫的伤害是明显的。在1 × 10码长的梯状断面上，通过对开阔盐沼上的杀幼虫试验表明，T. sp.3在沟岸的优势种群为T. nigrovittatus主要生活在开阔的、草较短的盐沼中。
Mass collections of larvae of salt marsh greenhead horse flies brought to the surface by applications of dilute lindane larvicide to mowed plots produced over 900 larvae between 1960 and 1963 at Leeds Point, N. J. These included T. nigrovittatus Macquart. T. lineola F., and a 3rd form here called T. sp. 3, a variant of T. nigrovittatus. These plots near ditch banks and on the open salt marsh yielded up to 20.6 larvae per square yard but all died. For life history studies and rearing to adults, drying salt-water cord grass on wire mesh-bottom racks yielded numerous uncontaminated larvae. Larvae of T. sp. 3 were collected by digging with a horticultural hand weeder at rates up to 17 larvae per man-hour in the ditch bank habitat. Collections by a flotation method produced 7 to 11 larvae per square yard but injury to larvae was evident. Larvicide plots as 1 × 10-yard ladder transects across ditch banks onto open salt marsh showed that T. sp. 3 dominated the ditch banks and that typical larvae of T. nigrovittatus arc primarily inhabitants of the open, shorter-grass salt marsh.
